[Q] Android and WiFi with redirects

Posted this in another forum, but you all are the experts. Impossible for me to access my work WiFi because of redirects (splash screen to accept use parameters).
Wondering if a custom ROM fixes it or if there is another solution.
Having an issue connecting to WiFi with Evo updated via official release of 2.2. I couldn't access it via 2.1 either. It's an odd network designation.
However, the iPhone can connect once I okay the error message.
Is there a work around that you may know about? Web search basically told me that the protocol is old and useless and that it should be changed. That is not possible.
Network designation is 1.1.1.1. I was unable to add links clarifying this because I am a new user.

Well Android can not connect to 1.1.1.1 addresses / networks / redirects. However the iPhone can. Is it inherent to the Android, or is there an app or tweak to get it to work.
This message ends by saying it will be fixed with Froyo.
Still can't post links to show what I mean.

Steamliver I just did a Google search for "Android 1.1.1.1" and this was the top result: http://code.google.com/p/android/issues/detail?id=1597
I'm guessing this is the problem you are describing. Sounds frustrating and it has been going on for a long time. The newest post at the time I'm writing this recommends installing the Fennec browser (Firefox for Android, basically) and that worked for the poster.
If you have a laptop you could bring to work and tether via USB, I wonder if that would work? Just a temporary work around to use the phone to establish the wifi connection, then view the browser redirect on the laptop, accept, and then maybe you would be good to go?
Also, the simplest thing might be to call the IT department and ask them for help. Given Android's growing market share, one of them probably already have an Android phone and a fix for this problem. Good luck.

I have tried firefox and that did not solve the problem, does anyone have another ideas how to solve this.
It seems that 1.1.1.1 is locked in the android.

[Q] Wrong ARP WiFi annoucements with JB ROMs

I've got a significant problem with my DHD when running any of the latest JB releases I've tested -- the problem appears with the JellyTime, codefireX, pipelinerard's CM and also the AOKP ROM's I've tested, even on a clean install (complete wipe of everything but the radio, install only the ROM; gapps not needed to cause the issue). The problem is however not manifest in IceColdSandwich, so I suspect something is broken in the way JB uses the WiFi network compared to how ICS did it. Maybe that triggers a bug somehow in the radio or misses some important radio settings?
To some/many people, it may not be immediately visible, but if you have this problem and use your phone on a large network, you might get banned/kicked off the network if they use rules similar to what e.g. Princeton recently implemented. You may also experience this as intermittent network problems with some hosts being unavailable from time to time.
Here is what happens:
Whenever the phone sleeps (i.e. the screen is off), it sends out bogus ARP message every 15.1 seconds (give and take 10mS or so). The message typically announces "IP x.y.z.v is at MAC ii:ii:ii:ii:ii:ii:ii" where the MAC address is the one of the phone and the IP addresses seems to come from some predetermined list and/or the routers IP -- or it might be 0.0.0.0.
On my network, when using one of the AP's, it will send out seemingly "real" IP addresses that will clog up the main router, trigger additional traffic to poll the ARP addresses and eventually cause misfunction and loss of connectivity also for other clients on the network -- it will however heal itself after some minutes, when the ARP cache times out, just to reappear again later randomly.
On the other AP it will always announce an IP of 0.0.0.0, which is obviously incorrect -- but doesn't cause any direct malfunction.
From time to time, I've also seen incorrectly formatted ARP packages.
I've debugged this with wireshark and pcap's on my network (as I started to wonder about more frequent network problems after using this phone).
I've also tried running tcpdump on the phone itself, and have inspected the pcap from the locally captured file. That pcap does NOT contain the ARP messages, so somehow somewhere deep down the kernel or in the radio, ARP messages are triggered to be sent out (i.e. below the capture interface).
To see if you have this problem, you need to run wireshark on another device and check for traffic from your phone's MAC address. It is easy to see if you know what to look for. You cannot know if you have this problem unless you check for it -- but you might suffer weird connectivity issues from time to time also on other devices/PC's, depending on the rest of your network components, that are not immediately discernable as related to the phone.
Technically this looks similar to ARP spoofing/flooding, with similar symptoms.
Does anyone have any ideas how to fix this? I think this requires someone with kernel/network knowledge, and it is likely related to how parts of the legacy parts (binaries) are being used.
I'm initialy trying to figuring out what runs every 15 seconds on the phone, and would then like to start tracing/bisect ICS vs JB code here.
Would also be nice if someone else could confirm this -- even though the specific symptoms apparently depend on certain WiFi related parameters.
Any ideas?
For reference, I'm using the latest radio 12.69.60.29_26.17.14.11_M. But as ICS does not have this problem, it might not be related to the radio version directly.

[Q] android most annoying bugs

hi,
well i'm against that policy, not able to post at developer threads under 10 posts, else I would have question that directly,...
I've tried several roms and ended at slim beam, first to 4.2.1 which states at stable but also tested the new one 4.2.2 build 2.5
actually i'm fine with the roms, also slim bean but I do have a 3 major issues with all of them which may be related to S3 and asop/cm:
1.) problem using my apple iphone earbuds (yes I'm a iphone user too)
sometimes after mute the microphone, it won't work after de-mute, keep on muted !
microphone not working after re-connecting earbud on a running call, sometimes no audio on earbuds too, sometimes audio even do not work for the whole device -> reboot etc,...
I've found several possible solutions, non of them has worked.
why android doesn't work with that kind of TRRS earbuds, are they incompatible from hardware point of view, do I need special ones which will work on S3.
2.) problem with direct dialing from calendar, not respecting RFC2806
i really need this very often to join conference calls, sometimes the host creates an conf call and including a number with pin as the location.
well almost every mobile os recognizes this and i'm able to direct dial in on selecting the string: iphone, win, even blackberry, but not android.
i know there might be additional apps which can handle this, but it should be implemented into core apps as this is a well known standard and specified in a RFC.
3.) not recognize AP with highest signal strengh within same SSID
it seems that android devices are not able to seamless switch over to different AP within a wifi network with same SSID.
if moving out of range of AP1 and into range of AP2, android devices for some reason are not able to switch to AP2 (with higher signal strengh), therefore it states at AP1 without beeing able to establish any connectivity (because AP1 out of range). as workaround users needs to disable/enable wifi ;-(
this is also something where I have to find a workaround in my current project (creating huge wifi network over europe), because market share of androids is that high and it still have this serious annoying bug.
thanks,
nean

1. Headphones > Most likely thats just an issue with roms that are version > 4.1.2. Not all the bugs have been worked out, see if you can replicate it with another pair of headphones.
2. I suspect the same thing is going on here, or you would need some more powerful calendar sort of app.
3. This isnt because it doesnt recognize, its because Android is still connected to the last network and says to itself "no need to scan again, I'm already connected". This has to do with how the OS is implemented, not because its a bug with Android. I'm also fairly sure that most other devices do the same thing

thanks for the reply.
ad 1,2,3.) hmmm, is this working on googles stock os and eg on nexus?
ad 3.) this is only related to android devices, as tested in the lab with several other handheld devices with different kind of os'es. ios, blackberry, windows mobile, etc, all work and do seamless switchover except android. well the last known network and the new one is actually the same wifi network which is specified due SSID, so if android's rescan logic is related to that kind of info it may be wise to consider acces point strength as well, just like all the other os'ses,....

Did you test using stock os and not a AOSP rom like stated in the OP? You can't blame the OS for a issue if it is moded in any shape or form. Try using straight up stock TW and see if it works. AOSP and CM are not 100% designed to work on this phone flawlessly.

thats correct, but it doesn't work on galaxy stock os either, that's why I've tried custom roms just to find out if its related to samsung stock rom or if its a general android behavior. well the outcome was that it works on aosp/cm a bit "better" (shorter timeout) but not seamless.
my intention is not about to blame anyone, just like to find out where I can adress this issue, or do I need to get in contact with google?

SOS! Please HELP - XM10T5G Down[&up]grading..

Have the Xiaomi Mi 10T 5G, which comes with Android 10 / MIUI 12 [Sort of combination of them i think], and i wanna install an older version of android only, lower than 10 [Preferably 7.0], is it possible to do at all? If so, then how exactly can i do that? if possible with exact instruction or guide to it..
Thanks ahead..
PEACE AND LOVE!

Not possible. I am really curious why would you even want that.

For many reasons.. They changed it in some very bad way for my opinion.. like the auto turning on WiFi by some apps, like some apps that don't have widgets, the call recording issue and many more very annoying unreasonable changes they did on A10 on.. saw also they only allow FBE encryption instead of FDE which is much better [That i can see for huge 128, 256 or maybe 512 Gigs Storages but still it should be up to the user decision not forcing]
So you say it's completely impossible? even if flash universal / rooted ROM? no way at all?! cause man those are really annoying stuff especially to the tech Pros and/or savvy's like us, and i know that since i saw many threads and posts in other forums about those issues too.. Maybe some giving up or thinking it's advancements, but really, maybe big money involved, espionage, and many more possible reasons they doing it.. It's bad, really bad..
* BTW sorry for the multiplication threads didn't knew it's SPAMing and not very involved it forums world..

To be honest I don't understand none of your points.
1. Wifi can be still turned on by apps, you just need to enable the permission (allow always vs. allow only when app is running in foreground).
2. Call recording is working in regions where it's not forbidden by privacy laws.
3. FBE is much better because it allows you to start the phone with basic service without using the password. Not sure why do you consider FDE to be superior.
4. Well, you can try to build your own Android 7 ROM from old sources, but you're going to have a fun time adapting to vendor partition/proprietary files created for Android 10 or 11. Also using several years old code which is not supported or patched anymore is quite interesting approach to security.

Maybe it's regional or SROMs based issue, but the vendor of the app said it's not allowed on Android 10 and on, and i did confirmed the permission to turn on WiFi automatically, but maybe there's some other settings that i missed and that guy was wrong, i'd love if you can show how to enable it globally and/or to just the auto file sync i use, cause i tried many times even with manual syncing [by clicking the Sync button when WiFi is off, it started and turn it off automatically on Android 7.0.. Of course also for time interval based sync]..

Hi.. Thanks for your reply.. i did that already before, but still it doesn't work.. i use FolderSync, that currently in my old Android 7.0 device, does syncing when i click Sync from within the app, while i was totally offline [Data and Wifi] so it turned on the Wifi connection [Specific home network], and also on Scheduled i inserted the Allowed Networks SSID [Which BTW when i turn on WiFi manually and it does sync it with GDrive, it say on top 'Unknown SSID' for case it matters {Had the feeling that it very much does}], I also switced it on in Data and WiFI limit it does on that Security app, which i guess is kind of firewall, and BTW i remember like 5-6 years ago i had the Lenovo A8 "Golden Worrier" has that same kind of Security app built in with firewall and all that, but still manually at least, as i checked, it doesn't turn on the Wifi via FolderSync app.. Got a strong feeling it's due to that Unknown SSID stuff or that Security app.. Could it be?..

FolderSync doesn't turn Wifi On automatically, this feature seems to be missing in the app. But I've just tested with Tasker and it is able to turn Wifi On and Off, so it's not a problem of Android version.
For Allowed SSID feature in FolderSync you must enable permanent location access.
Btw. I see no point in turning Wifi Off at any point, it uses so little power that there is next to none benefit in doing it. If you insist on some kind of automation, use Tasker in a fully controlled manner.

Well your first argument is actually not tru, FolderSync does turns on Wifi automatically as i do for like 4 years with my older Galaxy s6 [Great dev BTW, Samsung's first 64 bit device i thinks] running now Android 7.0, and also the other day and im sure if ill try this right now it will actually turning on WiFi from off mode and also automatically closed it when done syncing, but no matter what i did it doesn't doing it on the XM10T5G, and it both updated to the latest FolderSync version the one with those tiles.. so it must be something with the operation system.. again it's some kind of Andro/MIUI OS so it has to do with one of them..
About the SSID, i did confirmed the location access all the time [not just when it's used] on the Security app, is there any other place that i should enable location or any other settings that may be relating to this?..
And really? you don't see the point in using Wifi? It's much more faster, secure, and reliable than data.. of course i don't care if it'll be 4G or 5G even better to sync, but obviously not any connection, but thanks for the Tasker Tip, i'll try that.. i've heared that somewhere i think from the gut of FolderSync..
And BTW, the call recording is legal in my country, so i did also many years but here only after trying several apps i found Cube ACR working good.. And also, some apps ask you if you confirm that Call recording is legal in your country but of course if you flash custom or different ROM, the system obviously can never tell..
Peace..

Again security and energy reasons.. Think about it..
Anyway i barely know how to flash ROM, so i'm very far from building a custom one.. But at start you said it's impossible to install / flash an older Android ROM to it [XM10T5G], so you say it's possible with custom ROM?

WiFi random connection issue?

Hi,
So, I just got my S20 5G from Google Fi a week ago or so. I've been noticing that it suffers from little to no connections at times when connected to WiFi. No issue when on mobile data. I did online search and saw someone saying if I change the randomized Mac to Phone Mac, it would fix the issue, but it didn't work for me. I see numerous reports of similar issues on S20 series on the net:
Archived - Samsung Community
us.community.samsung.com
Archived - Samsung Community
us.community.samsung.com
I'd like to know if any of you have faced this issue and if you found a working solution. Some say it's a software issue related to OS update, but some say it's hardware. I want to avoid having to send this phone in or to replace if it's an OS issue since that won't do anything until Samsung releases a fix. But, if it's a hardware issue, then I should. I'd love it if I can get some data points from other people's experience with this issue.

Thank you for sharing your experience. If you come across any possible fix, please share. I'll do that same.

As a possible fix, do this. First check the setup of the Router. You can not use Mac address filtering since the mac address is changing r Randomizing your Mac and the router can no longer depend on a fixed Mac. Second as one of the Randomizing Mac settings where you set up the SSID on the phone set to "Use Device Mac" and be sure no other settings like in developers settings is turn on for Randomization. I'm finding setting it this way and filtering Mac addresses lives together but only for the session be that one-hour or days you phone is connected to the router. This is usually only a problem when you are filtering with router access list or setting a device's mac address to a Specific IP in the router.
