Model iterations & WIFI Problem - T-Mobile, Samsung Galaxy SIII

I hope to benefit from someone's WIFI expertise.
Bought for my wife a T-Mobile branded SGS3 replacing her older SGS4G ["S 4G"] model for more power, memory, etc etc. I noticed from the beginning that, compared to all my other handsets, tablets, PC/laptops, this one was troubled on WIFI connections. Found lots of posts around the web, read up on fixes. Gathered the tools together, erased the ROM completely, started from scratch with stock T-Mo ROM, rooted and debloated it. Made some of the standard changes to WIFI options: stopped scanning, disabled power-saving, reset the home/office WIFI to channel 11 , "N" band only. Things improved in that stable, controlled setting.
but 'on the road' with multiple hotspots, hotels, offices, T-mo data service, etc it is still very difficult to use. It will drop otherwise good WIFI connections, and hang in the midst of operating on WIFI. To give a simple example: go somewhere new, find WIFI, connect to WIFI, check EMAIL, Facebook, Messages - find 10 or so messages unread unresponded, try to download/read/respond and the device will get maybe one or two, then simply stop responding. Wait a minute or two and you get the "WIFI Connected" notice again. repeat, repeat...
What I wonder: how many variants of hardware have there been for T-mo, USA, GS3? Is there a model version I can get that avoids this issue?

Is the phone running full MD5 firmware?
Hardware issue if no restoring was done between devices.

yes, in fact I made utterly sure because somebody else asked the same question, same issue. still very flaky. no odd modems or other custom 'wares, just rooted and a few unnecessary apps uninstalled. how many models of this are there, were they made in different locales?
I assume the SoC is the same, but what about antennae, internal connections, etc? any evil interactions between radios? we don't use Bluetooth, so that one stays off all the time assuming the softswitch works

Well, as far as how many there are? A LOT! LOL! I'd imagine a few hundred thousand US variants, and for the T999 and its variants, close to a hundred thousand maybe? I really don't know, and those numbers did not come from anywhere but my head!
But as far as manufacturing, I am pretty sure they are all built in the same place. But, this does not mean that all of the components are from one location. In fact, from batch to batch of the same part, it can vary by where it was made, but also by what company made it. This is unlikely when dealing with the critcal parts such as the SoC, but the WiFi chip is a Broadcom chip. I have no idea if there are multiple manufacturing locations for it, but it is possible. The memory in all devices often varies greatly by the manufacturer.
Anyway, I do agree with Aerowinder. It is most likely hardware related. I'd look into a Warranty or Insurance exchange.

Wi-Fi Settings?

Can someone please tell me how -- or point me to an existing thread that will provide instructions for how -- to get AT&T's Tilt 2 to use wi-fi?
My situation is that I'm new to the Tilt 2, and I'd like to be able to access wi-fi -- rather than the slower than molasses 3G network -- when I'm within range.
My network is wired with a WAP, and it uses static IP addressing. I have no problem accessing the network with my (old) 8525 and my (newer) iPhone or my PDA or my laptop (all configured by me) to use my network to access the Internet and email.
My network is pretty tight (I think, or hope) in that it requires a specific IP address that matches a specific MAC address to gain access.
I've configured my router & WAP to accept a specific IP address for the Tilt 2, as well as the Tilt 2's MAC. I've checked & rechecked too many times to count to make sure I didn't make any typos. I've assigned the IP address on the Tilt 2 by going to Settings > Connections > Wi-Fi > Wireless Networks > Network Adapeter, and I set the Boradcom 8-2.11 DHD Newwork Adapter (is that the right one?) to use the specific IP addy I've assigned.
However, while the wi-fi icon indicates it's connected, I'm unable to use either browser on the Tilt 2 to access the Internet -- all I get are error messages.
I have honestly tried to read here for tips, and while I've read that I need to disable the AT&T proxy, the threads I found were a little (or a lot!) over my head.
I would sincerely appreciate any guidance.
TIA,
Saundra
Please, Need Help with Wi-Fi Settings
Surely I'm not the only one having problems getting the settings right so my AT&T Tilt 2 can connect to a home network, am I?
Honestly, I'm not a moron, but I can't figure it out, and the AT&T store was no help today, either. I recall that I had a similar problem with my 8525, so I went back & looked at my notes from 2008-- the problem was the MEdia Net proxy settings. On the 8525, it was a simple matter to uncheck the "This network uses a proxy server to connect to the Internet" box.
On the Tilt 2, however, I can't see where to give that a try because all I see is a message that says, "This connection is pre-configured. It cannot be modified."
Am I looking in the wrong place, or what? Or is that unlikely to be a problem on the Tilt 2?
I will greatly greatly appreciate any suggestions to try!
TIA
My first question is, are your WiFi router and the wifil on the TP2/Tilt the same? If the router is g and phone is N, they won't communicate.
That's a good question, and one I'd not thought of. My WAP supports B, G, & N & is operating in B/G/N mixed mode-- I don't know what the Tilt 2 is, but I'd think one of the three would cover it, yes?
Try going to this thread and downloading the files in post #13. Run the remove hidden proxy cab and see if that works, that will remove the hidden AT&T proxy server setting that often can't be disabled otherwise. The Tilt2 supports 802.11 b/g, so a router in mixed mode should have no trouble with that. You might try playing around with the network adapters again; I'd personally take another stab at the DHD adapter you tried earlier, since that is the one used on wlan connections. Also, you should probably make sure that the box which says: "My network card connects to:" is set to The Internet, and not work (this setting can be found on the Network Adapters tab of the Wi-Fi applet.
And while a bit off topic, you might want to consider adding additional security on your router (such as WPA2 encryption) if MAC filtering and static IP addresses are your only security; it's quite easy to grab both using free tools like aircrack-ng.
I want to thank you for your suggestions, but I'm not having any luck so far.
Scratch that -- things seem to be working . . . kind of. All I did was keep redoing the same things over & over, and suddenly, things are working.
I'm starting to think, though, that there's something wrong with this particular phone. Seriously -- I did nothing different tonight to get wi-fi working . . . encouraged by your comments, I just kept doing the same things over & over & over that I did last night.
Last night, running the removeHiddenProxy4CWS cab (it's in the Tools folder) resulted in not being able to connect to the Internet via 3G or wi-fi. Tonight, the results are different: I'm able to connect to the Internet via both after having run for the umteenth time the removeHiddenProxy4CWS file.
Further, while I've read many comments that the Internet is really slow on the Tilt 2, I'm thinking mine is abnormally slow & seems to hang up even via wi-fi. Now, I'll admit that perhaps my expectations are different coming back from an iPhone, but I charged up my old 8525, turned off the phone on the Tilt 2 to make sure I was connecting via wi-fi, and we are talking agonizingly slow on the Tilt 2 -- I was able to browse to six different Web pages on the 8525 in the time it took the Tilt 2 to partially bring up the first page (I used the same starting page on both). And, I say "partially" because it seemed to hang up at only partially displaying the Web site until I eventually hit the little circle in the bottom right of the screen. It does that on lots of pages -- is that the way things usually work on the Tilt 2?
Also, after my last soft reset just before things started working, I got a memory error message after I turned on wi-fi & when I hit the Internet button -- I should have written it down, but it said something about being out of memory on line 2. Any suggestions about that?
If the above are normal experiences for the Tilt 2, then I'll start learning about the tweaks to improve speed & such. If not, then I guess I need to try to exchange this phone. <sigh>
I also really appreciate your a bit off topic comment because I'm a security freak but not sure I understand much! My WAP uses WEP 64-bit encryption in addition to the MAC filtering & static IP addresses, and my wired router has a firewall -- does that sound sufficient. None of my neighbors can "see" my network, and it can't be seen from the nearest public road -- does that sound relatively secure?
Most of your Tilt2 problems could be fixed by flashing a custom ROM. If the phone is a business phone (as in it belongs to your company) or you otherwise can't void the warranty, a custom ROM sounds about right. It will improve the device's speed on all fronts, and will also have more available memory on bootup (mine had 25% less RAM in use on startup with a custom ROM). On my Tilt2, using a custom ROM with the latest Manila 2.5 build, things are still quite snappy, and pages load quickly on 3G and EDGE. If you'd like to know how to put a custom ROM on your device, this link will tell you everything you need to know. If you decide to put a custom ROM on your device, keep in mind you'll lose all the data on your device if you don't back it up.
As for the wireless security: WEP is extremely insecure. It has been proven insecure for many years, and has been replaced with the WPA (okay but obsolete now) and WPA2 (best current router security) protocols. Cracking WPA/WPA2 is much more difficult, as it requires a password cracking program and a wordlist to crack downloaded traffic obtained from the network, which can take days of cracking, sometimes ending in failure regardless. Unlike WPA/WPA2, WEP is much more vulnerable to many different attacks, from programs like aircrack-ng, which are free and readily available. If you don't believe me, check out this video of WEP being cracked on a test router, with the Backtrack 4 Beta security Linux distro, in as little as 2 minutes. MAC addresses and IP addresses can also be grabbed with many readily available tools, and the MAC can then be spoofed quite easily with free programs. And even a hidden SSID can be grabbed with a program like Kismet, which scans all wireless network traffic in an area (regardless of the network it's on) and can grab the hidden router's SSID during the handshaking process (when a client computer connects to the router). If you're absolutely positive that your network can't be detected from any public road (as in, there's no signal whatsoever), you're probably okay and can probably sleep safe at night. But, unless you have old equipment/software which doesn't support WPA2 or WPA, I'd recommend upgrading to the latest WPA2 security (if you're really concerned about security/privacy).
I really appreciate your help!
The Tilt 2 is a week old -- it was a birthday present. Am I correctly understanding that I could flash a custom ROM & then flash back the original if I don't want to void the warranty?
If so, playing with different ROMs would be something I'd be interested in doing . . . I just don't want to void the warranty in case there is something wrong with the phone. I had lunch with a friend with an AT&T stock Fuse (I think) Thursday, and we were playing with each other's phones. I can't say that I noticed her Internet was any faster (I wasn't really paying attention), but she was quite surprised that both IE & Opera failed to display a complete page until the screen was touched. On my end with her Fuse, Web pages opened completely with no fuss.
So, the whole "hang" thing makes me very nervous, particularly with the "out of memory" error message with nothing other than Contacts on the phone yet -- I've not even bothered to configure email (my lifeline). I was hoping the Web interface (I have IMAP) would work OK since that was one of my big beefs with the iPhone -- the onscreen keyboard just didn't work for me. But, with The Tilt 2 taking over 60 seconds to even get to my web-based Inbox, the Tilt 2 is gonna be a problem unless I can get that resolved. Hence my concern about not voiding the warranty.
You are correct: I do have older equipment that only supports WEP. My PDA & my old 8525. If I can get the Tilt 2 working well enough for me, I can rotate the older stuff out and go with stronger wireless security. I know my neighbors can't "see" my network, but I've never tested from the street behind my house since the closest neighbor behind can't see the network. However, due to the configuration of my neighborhood, I'd best check that street. <gulp>
Thanks again -- I really appreciate the help.

Sure, I'm glad I can help. Well, you're partially correct about the whole ROM thing. The deal is, your warranty is only voided if they know you put a custom ROM on it. If they don't find out (ie, you restore the ROM and SPL to their stock counterparts) you're good to go. However, you do technically void the warranty because you put a third party ROM. However, you can take it from me when I say it's almost 100% safe when you follow instructions and it's completely worth it. You get more features and stability with less bloat while using an unofficial ROM. Keep in mind that if the USB port goes bad, you can't restore the device to stock configuration, and you'll have to pay full price for repairs (unless you dispute the warranty violation in court, and try to prove that there's no way an unauthorized ROM broke the USB port). Otherwise, a custom/cooked ROM is completely worth it, and will greatly improve your whole experience over the stock ROM.

Kaiser 110 problems

Greetings all --
I am posting this request for help because I've exhausted just about every other resource. The community support and documentation is great and I have learned quite a bit in a matter of days. You all are great!
Here's my situation. I have the HTC 8900 (KAIS110). Not the 8925 like most seem to have. It is my understanding that 3 versions of the "Kaiser" were made, or at least submitted to FCC for approval, and that the 8900 was to go to AT&T (branded on phone), but was canceled in lieu of the 8925. This is the non-camera version.
For reference, the following information is listed in the battery compartment:
HTC 8900
KAIS110
FCC ID: NM8KS
SKU: 64760
P/N: 99HCY091-00
Made in Taiwan
Currently:
HardSPL 3.56
Radio: 1.71.09.01
Myn's Warm Donut RLS5
kallt_kaffe's kernel 2010-06-06 (kaiser/240x320/donut/panel 2/tilt options used in LoserSkaters NBH Editor)
Problems:
1. Installing OS (Sys+Data on NAND), dmesg output shows "Block 711 is bad". Under normal circumstances, this wouldn't be a problem as the OS would remap to a new block. This could also be an issue with yaffs, or a few other things, and not even be bad. But the question remains, is this causing problems?
2. Attempting to run Calibrate Screen results in error with the following message: "The application Calibrate Screen (process org.isageek.dasbrennen.CalibrateScreen) has stopped unexpectedly. Please try again. [Force close]". I have not seen a recent post in response to whether this problem persists with all builds, or if I am just lucky like that.
3. GPS does not want to play nice. From the app store, I install GPS by Andrea Baccega. Sometimes I get a single satellite to display, once I saw 3 on screen. Unfortunately, none of the other fields (long/lat) were populated which tells me something is wrong.
Dmesg output:
GPS:env_mask=0
GPS:date=00002000
GPS:time=000000 hlat=0 llat=0 hlng=0 llng=0
GPS:speed=0 bearing=0
GPS: has been tickled!
4. Using the phone on T-Mobile, why can I not get 3G working? It keeps going back to EDGE. I have the Android data plan as well.
5. Voice search is quite flaky. Sometimes it works great once, maybe a few times in a row, and then it just stops working and presents me with the Try Again / Cancel screen, after which, there is no longer audio for phone calls. From what I can tell using Dev Tools, looks like VoiceSearch is hanging due to an issue with Mediaserver. I recall seeing this issue, or a similar one, surface in the forums but there was not much information pertaining to it that I could find.
6. The following errors appear in the dmesg output; I am posting the list just in case one or more messages are beyond the scope of normal operations:
mmc1: host does not support reading read-only switch. assuming ite-enable.
Init: cannot open '/initlogo.rle'
[RR] ERROR no local ept for prog 02000031 replying anyway!!
audio_enable()
audpp: DMA missed
audio timer expired
audio_disable()
audmgr: DISABLED
binder: send failed reply for transaction 5448 to 149:221
7. As stated above, this phone lacks a camera. The slot where the camera goes, just has a cover over it. Looks like I should be able to pop a replacement in the spot. Anyone know the part number of the rear camera, or where I might find one? I can only seem to locate the front-camera on various web sites.
Thanks all!
1. bad blocks are common, yaffs reports them, and marks them as unusable, they have no effect on running Android, ( one of my kais130's has about 10 bad blocks, works fine).
2. Thats normal also, not sure if calibration app has ever worked, although i think there is a console based one that does, never had to use it though.
3. GPS may or may not work properly depending on a number of factors, which build and NBH are used, also which gps software is used also, best combo I have found so far are the Kallt_Kaffe NBH's and Myn's warm Eclair, with GPS test (free or pro). Also note that initial fixes take some time, up to, or over 5 minutes, depending on conditions, etc.
4. Not sure, could be a number of factors again, build, local 3G coverage, APN setup, etc.
5. Never used voice search, but it is known to be pretty flakey, again build plays a large part.
6. I know that there are normally errors on boot, the audio ones are not normal however, could be due to using an older radio, or perhaps some rare kais110 issue, can't actually recall anyone reporting issues with kais110 hardware.
7. Not sure if it's possible to just add a rear camera, it'll depend if the supporting electronics were fitted to allow it to work or not, also unsure where to look for one, although you may be able to get a part number off the service manuals, ( should be in the xda-wiki pages ).
TMobile and AT&T use different 3G frequencies, so an AT&T phone such as your won't do 3G on TMobile. The EDGE will work fine, but slow of course.

Use GPS Test (chartcross ltd), free version from Market. Configure it to not turn off display (keep it from going to sleep). Plug in a charger (if you wan to) and leave it near a window.
Within 5-10 minutes you should have a fix. After that, getting a fix normally happens within seconds. Depending on how much time has passed since you last used your GPS and also the distance you moved it while having it turned off also affects the time to get a fix.
Also blocking the top of the phone with your hand is not a good idea as it seems to be an effective way of blocking the GPS signals.

Thanks for the response -- I had tried that over the past 2 nights, but it never took. It just did however, during the day, which is odd. I also switched to a 1.64.08.21 version of the radio today, and it worked. Previous attempts were under 1.71.09.01, 1.70.19.09 and 1.70.18.02 that resulted in failure. Odd.
Is there a way to view all roms installed, for everything? OS, kernel, radio, splash/boot, etc? I am wondering if something got hung up during flashing, or something didnt get wiped out.
Thanks!
purpleonyx said:
Thanks for the response -- I have done this several times (left it going for 10+ hrs at the max time), and it picks up 4-5 satellites, but nothing ever occurs. It sits there with the yellow light, and all of the numbers show in the 20's to very low 30's, which seems like it's a very weak signal, or a high signal/noise ratio. Could this be a radio issue?

20-30 actually should be enough. Anything above 40 is excellent and not seen very often. And I'm using the same Radio so that should be the problem. Don't know really. Does it work in WinMo?

I had no problem working under winmo before i flashed android to nand. It had no delay in picking it up either. I just rebooted the phone and launched google navigator, and it's taking forever again, searching for gps it says.
If you want to use me as a guinea pig, feel free. I ended up ordering the nokia n900, as i need something working now. I am considering keeping the kaiser 110 to screw around with though. It would make a good backup device anyways. I tried Myn's Warm Eclair on it, but it dragged its legs and had too many problems. Myn's Warm Donut however, functions near perfectly and is quite fast. I've oc'd the processor to 450 MHz which provides a noticeable speed boost. I'm using your latest 2010.06.06 kernel with it. I've been questioning whether or not display 2 and 3 are the same on this model -- sure behaves the same.
-update: Phone comes to a crawl, and then locks up when GPS is used. Both the GPS Test and Google Nav.

[Q] How to modify radio CDMA parameters?

I have been having a lot of trouble with my Epic's radio behavior since the EC05 radio update. It seems that the normal Samsung "radio stupidity" that I have seen in several of their devices is worse than ever now. The best radio for call performance I have used so far was DG27's (though not data). Essentially, what it is as far as I can determine by using utilities to monitor radio operation, is poor CDMA handoff configuration.
What it does is, for no good reason, switch from a cell site providing a good signal level, to one providing a bad signal level for no reason. Either this, or it holds onto a weakening set of towers while moving, until it goes out of their range and the call drops. The phone will then display the no service message for a few seconds, and then will pick up perfect signal from a different set of towers. I can even watch this happen by driving down a given road while on a call, with another phone in my cup holder. The Epic will start to break up and show very low signal levels, while the other is doing perfectly. Additionally, the direction you drive down this (2 lane) road also has an effect.
I have fixed this before on non smartphones by altering some of the CDMA radio values. T_Add, T_Drop, T_Comp, T_Tdrop. My solution is to increase the threshold on T_Comp a little bit, and drop the T_Tdrop also a little bit. The problem is that I cannot figure how to do this on this phone. Very little radio information seems to be available, and the utilities I have do not work completely on this model.
This issue with how they program their radios seems to be a common Samsung problem, to a much greater degree than with other manufacturers. Sanyo, Palm, and Motorola seem to do a much better job with this, even in cases where they use the same radio chipsets.
I am feeling like a lot of people will find this matter interesting and/or of benefit to resolve.
The only problem I see and I'm sure someone will correct me is the RIL is closed source. Also android was designed around gsm and not cdma. This makes the manufacture and carrier to design a "wrapper" to get the RIL to work on cdma. Now if samsung would release the source.code I'm sure making changes wouldn't be so hard
On a side note I know there's a dialer code ( I forget what it is ) that you can go and play with some settings. One of them being able to switch to cdma instead of cdma/gsm that it is by default.

My data does the same thing on ec05. I'll have perfect signal and then all of a sudden nothing for like a minute and then it comes back. Least im not the only one

It isn't the data driving me nuts. Data sessions pick up again quickly. It's the dropped calls. Either way, it is partially a symptom of the same problem. The phone is promoting weak towers, sometimes in favor of strong ones, to the active set - which it should not be.

No and yes. CDMA support was a hack in versions prior to 2.0. Android 2.0 (and later) has inbuilt features intended to support CDMA networks. Some of the companies are still using some legacy code, and some of nomenclature used within the system parameters still reflects GSM however.
This, however, is irrelevant in my belief. I do not think that these parameters are a function of RIL, as RIL is simply the intermediary between the "computer" and "telephone" components in a smartphone. I believe that these issues exist purely, or nearly so, within the "telephone" section of the device.

Not ###47852#. *#147852#. I don't know the name of the dialer. I call it the master meenu. It basically let's you access various front end user settings on the phone. I have used it to reset my 4g radio. Anyway, you may try the testing/phone information menu to change the cdma setting. I'm totally taking a shot in the dark on that, but it does seem to allow you to alter the radio preference.

Yes, totally misread that. Nothing seems to apply however, as I do not think it is a software parameter on the phone end. The WiMAX radio is software controlled, through a driver in the operating system. The combination of CDMA radio and baseband processor are more or less an independent device which essentially lives on its own, with its own configuration. It is told what to do through the RIL, which is a piece of software that allows the computer aspect of the phone to talk to the radio, passing it instructions which it then acts upon according to its own programming and configuration. The RIL also allows the radio to communicate its status to the rest of the system.
I am really thinking that this will not be a setting that can be modified from within the phone itself, but will require some external involvement, similar to QPST. On this chipset, however, QPST does not appear to be able to manage these parameters.
If you find out any more info please pass it along. Thank you.

Ah that's really interesting. Wish I could help.

is sprint store employee right? - horrible network problems

Took my Note 2 in for help today. Phone refuses to update Outlook data. hard reset, etc.
Duplicate results in store. Tech explains that this is in fact a Sprint problem. It is a by product of their efforts to upgrade their network and I will not have outlook data for the next 3-6 months. It may be spotty, one day yes, then nothing for a week. There is nothing they, or anyone else can do.
He suggested I call retention for a credit, but told me all carriers will be going through this soon.
So much there to digest...
First off - really this is all network trouble?
Second - ATT, Verizon etc are going to have this problem in the future?

The thread title should read:
Sprint store employee IS right - (Sprint has a) horrible network.
Well, sounds like you need to do trouble shooting because there are a number of things that can be causing your issue. Assuming you have internet at home through something like a cable or DSL provider, I would check to see if you can update Outlook when connected to your home network. If it doesn't work, assuming there isn't a firewall issue, then the issues is on the GN2, most likely.
If it updates, then the apps is ok, but it's something else. I would look into to make sure you have data connection. If you can use the web browser and load pages you haven't visited, Netflix, Pandora, or something that needs an internet connection to work, then it's within the app. If no data connection, then it's Sprint or device issue, and what the employee could be accurate to your situation.
I'm not familiar with Outlook, but if it's an app, I would look in it's settings. You may need uninstall and reinstall. Maybe relink your account or something.

Outlook data to a pc went through wireless tether yesterday. I cant imagine that is true, that would disrupt every corporate employee on the network... even their own.
Seriously?

I agree with your trouble shooting tips, but you don't know what Outlook is??
Sorry, I guess if you haven't worked in a corporate environment you may not have had to deal with Outlook before. Outlook is actually Microsoft's e-mail client for their Exchange (e-mail, calendar, contacts, to-do task list) Server and it only runs on Windows.
What he is really referring to is updating the Exchange Server which is supported by Android and several Android based e-mail clients. Exchange is used mostly in Corporate and Government environments but it is not exclusive to them.
As I said, your trouble shooting tips are exactly right. I have had a lot of trouble with updating Exchange over the years and it seems like it is hit-or-miss as to whether it is going to work from one day to the next.
However, I don't know of any reason why you would not have access to Exchange for weeks at a time due to Sprint upgrading the network. And even if you can't get to it through the 3G or LTE Sprint network, you should still be able to get to it through a Wi-Fi internet connection.

One of the things I checked, as it would not update the Exchange data over wi-fi in the sprint store.
Curiously every Samsung device I tried (tablet 10.2, Note 2 and S4) had the same problem. But HTC devices did not. So I now have a One.

LOL, yes I know what Outlook is. I have worked in the corporate world and used it. I didn't work in the IT department. I even used it at home for a while. I stopped using it years ago.
What I meant was that I wasn't very familiar with mobile version and how it is setup. I only mentioned it to let the person know the limits of the help I was able to provide. I'm pretty good with general trouble shooting and narrowing where the issue may lie, but if it was app related, I probably wouldn't be very helpful.

That is strange. My Note 2 works... most of the time. My Transformer Prime tablet works... most of the time. After you said that I realized that I didn't have any problems with my old HTC Evo either. I wonder what it could be about Samsung that Exchange doesn't like.
Exchange doesn't play well with others.

I kinda like Outlook on my desktop. It is very stable under Windows. I don't think there is an Android version of Outlook; if there was it would have to come from Microsoft.
Back to OP's notes. I mentioned this before and it was confirmed by an XDA user who's also a regional tech. There IS indeed a network issue and those affected should be on PRL 2000 to help mitigate that. It does suck because you don't get all of the towers - and as long as the N3 comes through with Tri-band why I'll be trading this one in for it.
Some of the things that may happen: No push notifications (async updates), inbound calls, etc to the device. Sounds very similar to what I had for a few months.

Is there a reason this would only affect Samsung? What you are describing is basically what was happening with the N2 and similar to the explanation given by the Sprint tech. It was quite maddening when it would actually load several days of data, then they would suddenly disappear while the tech was holding the device.
What is interesting to me is that the HTC is not affected by this. Though the general radio strength is weaker on that device, apparently it does not have the data problem.

S4 also isn't affected. At the time I was told this was related a new network feature - SO73.
http://wireless.agilent.com/rfcomms/refdocs/cdma2k/cdma2000_gen_encoder_oprtp.html
...and it was only in certain markets. Since they are saying every other carrier will face this it makes me think it's a data compression or VoLTE thing where not every phone was designed for the network upgrade and will take it well.
It would seem device specific if this was working or not. Beyond the N2 I heard some iPhone users also say they've been pushed to PRL 2000 - not sure if it was for the same reason. And if you're not on PRL 2000, get on it. I still have issues in a few remote locations but it is 90% or more less than what I was having and could re-create on demand.
All the more I'm eying the Note 3 as a possible replacement.
Have you tried using a different e-mail client for your Outlook sync? It may be an issue with the Samsung email client and your Outlook server config.
Personally, I have a Note 2 and Note 8 and have fine connection with my company's Outlook server, but I do note some issues with keeping the config settings up to date.
Does your exchange server require your phone to be encrypted. My Company requires this for the sync to work properly. Not sure why it would be intermittent though.

actually no, though it would make sense if that were an issue, however, as you point out, it would not be intermittent.
The final answer I received from Samsung technical support was that their latest email client does not support "older" version of Exchange and Outlook. We have 2010, which Samsung refers to as outdated.
Curiously, Sprint uses the same version of Outlook.
After switching to an HTC One, I have no problems at all.

Returned home from short trip, Wifi connects but does not function

As the title says, I didn't change anything about the phone's configuration when I was out, didn't download any new apps or change any settings that would interfere like this. No one else has changed my home network in my absence.
Nevertheless, most of my apps, such as Instagram, the Play Store, Twitter, Wikipedia, Chrome; almost all their requests time out. There seem to be short windows where data will load, and Instagram appears to load comments and post metadata, but no images. It's basically unusable. Occasionally an exclamation mark will pop up over my Wifi symbol in the notification center. Strangely, I can still reach my Steam and Battle.net authenticators, but the moment I try loading the Steam app, nothing comes up. It's like the device can only handle plaintext over Wifi.
All of the apps work fine over cellular data.
Also, there is a toast that appears whenever I restart my phone that says "Power On" that I've never noticed before. I was rooted using Xposed, the only modules I used were Snapprefs, Xinsta, Physical Button Music Control, and Greenify Experimental Features, all of which I uninstalled. The toast still appears with the latter two disabled. Only other rooted apps I had besides Xposed were Nova Launcher, Greenify, Busybox, and Root Checker Basic, all of which have been removed but Nova.
I am running 6.0.1 with the latest update.
Any ideas? I am still within 15 day warranty so I could theoretically return the phone (which I was contemplating doing anyhow since 10gb of functional storage is a bit too small for me), but would rather not have my hand forced, and eat into my cell data plan.
So far I have tried forgetting the network, wiping cache/dalvik with TWRP, removing the Google VPN, resetting all network settings, and a couple things I can't remember offhand now. Any suggestions will be appreciated.

First, if you want to return your device because the 16gb model doesn't have enough space, go ahead.
If it is mostly because of this WiFi issue, I wouldn't return the device, it is almost certainly the case this is some configuration issue (possibly in concert with some Android bug) which can be resolved.
Is it possible when you came home the device connected to a neighbor's AP and thus you couldn't use data, but it wasn't immediately obvious, so you ended up forgetting your own network and reentering the config, but the key was off by a little, and from that point on, it was just assumed the wifi config was correct?
When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?
Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.
Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I am 100% positive I am on my own home network and that I used the correct key. I'm not sure what you mean with regards to the rest of the 'config', I have always used the standard wifi configuration, just typed in my key and had it work.

I actually forget what it was called, it was under Settings>Wireless&Networks>More>VPN. There was one entry there with an icon. I forget the name of it, but the icon looked like a stock Google icon and I think it had google in the name. I am on Project Fi, not using any wifi assistant (at least not in Advanced Wi-Fi Settings), but when I tried to toggle that option on just now, something called "VpnDialogs" crashed, so I assume that VPN entry was that. But again, the assistant wasn't on.

I don't use Bluetooth, and trying to toggle it off/on from the control center just gives me a repeated "unfortunately, Bluetooth Share has stopped" error message.
I have decided to get the 32GB 5X since I do want more storage, but since I would like to be able to root my phone again and use Xposed, I would still like to hear any other ideas you have for troubleshooting this problem in case it reoccurs.
I reflashed the latest update to see if that would fix it, no dice. When I send the 16GB model back I have to factory reset it anyway, so I suppose I'll know if that does it.
What puzzles me is why I can load text from instagram posts that have been posted while I've been having this problem, but not images. Makes me think that maybe my connection is being super throttled somehow rather than non-functional, but my PC's speeds are normal. Perhaps some internal part is damaged? I do have a case and it hasn't taken any serious tumbles, but it has had one or two small falls from maybe 2 feet high.

It is easy to test if you have some network connection vs none.
In terminal or adb shell
ifconfig wlan0
ping www.google.com
1st command will tell you (among other things) if your wlan picked up an IP address.
2nd command will test whether you can send ping packets over your connection.
I'm sure there are millions of ways of doing the above, I just gave you one example.
Strangely, the solution seems to have come from factory resetting my router. I ruled this out initially because my other old phones were working fine on wifi, my phone is now getting WiFi again.
Now to figure out what the hell this "Power On" toast is about...

I've encountered something similar where the router runs out of NVRAM space because it has recorded too many DHCP clients, it won't hand out new IP addresses, but if you are existing or already have one, it is fine.
