Network Vision and 1xRTT

So I noticed in downtown Milwaukee that I was stuck on 1x, but had full bars (on the sprint network). For fun I did a speed test, and was floored... 70KB (yes, bytes, not bits) down, 45KB up. I will upload a screenshot later when I can get to a PC.
I thought our phones wouldn't be able to take advantage of the upgraded data capacity of 1x?

That's what 1x is... It's far, far slower than 3G.

Yeah that's 2G lol

1x can't do 70KBytes/45KBytes
How are you determining your are on a 1xRTT connection?

The network icon in the status bar indicated 1x... I didn't believe it, so I checked Netmonitor (confirmed) and also did SpeedTest... See the screenshot of the details of the test.
Either funky things are happening with 1x, or my radio is reporting the wrong connection type. Although I know they are upgrading the 1x network somehow to accommodate the extra traffic Direct Connect is bringing... But as far as I know, the theoretical max of 1x is about 18KB.

With those ping times I can almost guarantee you are not on 1xRTT. Your data rates are even beyond the revised 1xRTT rates.
I am surprised they put the 1x notification back. Previous releases always said 3G regardless of whether you are on 1x or EVDO (on multiple sprint high-end phones)
What does ##DEBUG# say about your data connection?
When it asks for your lock code enter 777468 (SPRINT) (the equivalent #s from a phone dial pad)
BTW what is that 3rd notification icon (from the left) signifying?

Next time out drops to 1x, I'll check out debug and post here.
I'm running Calk's last gingerbread ROM. He has the 1x / 3g fix baked in. Until the last two weeks, I never noticed high speeds when it indicated 1x, but of course it's possible something on the code is reading the state wrong.
That third icon is the standard Android notification letting Mr know there is an open wifi signal.

I missed you were on GB, answering so many ICS questions today.
For ##DEBUG# on GB, enter your MSL which you can get using "getprop ril.MSL" in adb shell

Is Wi-Fi really problematic on Note2?

I see reports of problematic Wi-Fi for the Note2 & I've heard the multi-view update (for AT&T anyway) will also include Wi-Fi improvements so the question for current Note2 owners is just how problematic is Wi-Fi really at this time?
-Thnx

Not problematic at all

I personally haven't seen any hardware deficiencies on this device, and no major software issues. Wifi is stable, the hot spot is stable, bluetooth is stable, and I'm getting higher speeds and better connectivity then I've ever seen on tmo's network.

I also have no issues with wifi what so ever. Great phone! Everything works as it should; minus having the multi window update of course.

Good to hear about the Wi-Fi as I use Wi-Fi a lot & it could have been a deal breaker. I'm hoping T-Mobile will feel more pressure regarding the multi-view update when Verizon this week launches with it & AT&T who has worked on it for a while updates it. Sprint the first major carrier to get multi-view is my current carrier with the EVO which will see its 2 yr contract end Saturday so I ordered http://www.amazon.com/gp/product/B00A45SF7G last night-should arrive Friday. Would also like to see this white case when available as I'll likely be getting the Note 2 in grey & want to see it in these black & white kickstand cases like my black EVO. I'll also get http://www.amazon.com/Seidio-CSK3SSGT2K-BK-ACTIVE-Kickstand-Samsung/dp/B00A45SGKC when available again as my EVO & seen in Seidio Active and Surface Case Unboxing and Review for the Samsung Galaxy Note II .
I hope T-Mobile doesn't wait until the Note 3 to update to multi-view & what ever happened to the screen recorder function?

Wifi connectivity is awesome no issues.

So do you all think the reports of Wi-Fi issues are just isolated issues then?

"WiFi
The Note 2 uses BCM4334 for WiFi and is enabled for both 2.4 and 5 GHz. Just like the Galaxy S 3 that means 40 MHz channels on 5 GHz for a maximum physical layer speed of 150 Mbps. I did have some weird issues here, no matter what I did I couldn’t get the Note 2 to go on the 5 GHz AP, or get up to 150 Mbps.

Curiously enough there isn’t any 2.4 or 5 GHz priority toggle under the advanced tab in WiFi settings, yet the Galaxy S 3 models have this toggle and the same WiFi hardware stack. I suspect there’s some software or configuration issue here.
As a result we see iPerf performance out of the Galaxy Note 2 along the lines of what you’d expect for just 2.4 GHz operation. I’m puzzled as to why this is the case quite honestly."

My wifi sometimes disconnect and reconnect a few times a day. Never had any problems on my sg3. Don't think it's my router. I passed my returning window.

I did have that problem when I first bought it actually. I tried disabling the wifi sleep option by doing these:
*#0011# > press menu key on phone > WiFi > click the "ON" button so it does't light up (basically turn it off).
It seemed to have solved the problem but still seem to happen rarely. I thought i had a dud but after I did a factory data reset and all wifi problems were since solved.
My friend did a factory reset before he even used his phone and he never experienced any Wifi problem. Hope this helps...

Thanks. Just turned off the wifi sleep mode in phone setting. Hopefully this will help with wifi dropping.

FWIW I've been a tad disappointed in the WiFi, performance seems okay but it's finicky about routers. I've got a mid range Cisco unit (500 series) at home and it will not connect to the 2.4ghz side at all, but will the 5ghz. At the office it's the other way around (Engenius business grade stuff). Once connected it's been fine, seems slightly slower over wifi than the original note but otherwise fine, it's just picky and takes some extra steps for me. I've upgraded to the latest firmware on my router at home with no change, not that I expected one as the release notes had nothing applicable.

any ideas what are the difference between the wi-fi power saving from this menu vs the "keep wifi on during sleep" in the phone settings? They seem to turn on and off independently.

I'd check the Wi-Fi sleep policy but curious why a factory reset before using the phone would help as shouldn't it already be in a factory reset state before using (i.e. what your friend experienced could have just been a coincidence)?
Good to see that this is not in fact a common experience..

Note 4 WiFi Speeds

What kind of speeds are you guys getting on your home wifi? For some reason I'm only getting about 7Mbps down, on a 12Mbps service. My PC confirms that I am getting 12Mbps when I run speed test from there, but my Note 4 won't do much more than 7 on the same connection.. Any ideas?

I don't see any problem. At 50 Mbps service i got over 60 Mbps

Definitely have issues since update
My WiFi seemed to work fine when I first got the phone. I took the OTA update and since then I'm getting about 25% of the speed I do on my PC. AT&T is ruining a great phone

I've also had some off wifi speeds since the update. Have 20mb/s at home from my ISP and will randomly drop to 5mb/s but the speed on my laptop will be fine. It's not consistently slow though so i'm not sure the issue.

Wifi slow since update
I'm also having a very similar problem. Everything works speedy over LTE, and it seems its fast on the wifi networks at my work, but my home wifi is incredibly slow. I notice it most with the Play Store, Google Now, and Maps. Images don't load, links/results load slow. Updating apps takes a bit longer.
I did a test and while on wifi, I used the stock Internet browser app and did some searches on google.com, which all returned immediately. Doing the same searches on the Google app took 3 times as long to get the same results.
I know this was an odd test, but I used OpenVPN Connect to VPN in to my home network while on LTE. The same problems occurred over VPN. At first I thought that it was my home wifi, but neither my Nexus 7 or Galaxy S3 have these problems. I'm hoping this gets fixed when the Lollipop update rolls out.

Yea, it's weird because my girlfriend and I have identical note 4s. She hasn't updated hers to the latest os version yet, and she is getting the same crappy speeds on her phone. When I test my speed on my PC I'm getting what I'm supposed to get. Idk, maybe it's this crappy dsl service we have. I'll have to run a test on someone's cable service and see how that goes.

True I prefer cable over DSL any day.

I've had this issue for a while,I use xfinity. I have the WiFi router built into the modem with telephone also.ever since they thought it was cool to make my WiFi a xfinity open hot spot for any customer that sits out side my house and wants to use my router they can,as long as the sign on with there xfinity account.I've had all kinds of wifi issues,my hardwired connections are fine.My WiFi speeds get so slow my phone goes to LTE until the connection gets better.I called and had them disable the hotspot from info I got searching google,they did.It seemed OK for a few days,then same issues.This has been going on for months I'm going to take the modem in a get a new one,but I've read people doing this and still issues.This has happened on my S3,S4,S5.On my note 4 same issues but I have a new one,even when my WiFi is strong and stable certain things won't load even tapatalk,if I toggle off WiFi on my phone and refresh on LTE no problem connects like it should.I disabled power saving that was recimended, but I don't see a change in anything.Even after it refreshes I don't see any stat changes in the dialer WiFi menu.What I does the WiFi power saving mode do anyway?

Yes, most definetly. Cable is far superior to dsl presently. We can't get cable where I live, and dsl is my only viable option. I read about a new technology that is being worked on, that when completed will enable data to travel up and down dsl infustructure several times faster than cable. I don't recall the exact numbers, but from the sounds of it, there's a good chance that dsl may become the preferred infustructure for ISPs in the future. Here's the link to the article that goes over it.. I thought it was really interesting.

4G not working on 1.80.401.3

S-OFF, LOCKED
Running 100% offical 1.80.401.3
4G does not work. It show 4g/4g+ and max reception in status bar but when i try and run speedtest it fluktuates from 2-5 bars and flip between 4g/4g+. Speedtest failes after 30 sec or so.
Same sim card and same location gives me 110/mbps (yes!) on a Samsung s6 so its not the network or the sim-card.
this is after a full factory reset.
any tips?

To add to this, 3G works just fine if i switch to it manualy.

custom rom or stock?
LTE+ works fine for me no drop in network or signal...same firmware and on custom rom here...

100% official 1.80.401.3 ..... says so in the first lines. So my guess would definitely be NO custom rom !

There have been many threads and complains about wifi and 4g reception. My wifi works fine (not the best, but its decent). However, 4g reception is pretty bad. Mainly in indoor places, 4g shows no bars. I guess the problem also lies in the phone not automatically switching to 3g when 4g is bad. Sometimes i get no signal when there is actually 3g service. If I force the phone to 2g/3g only i get full bars. It's probably a firmware/radio issue that will be fixed in the next update hopefully. Chek the threads about weak wifi and weak lte for updates
Sent from my HTC 10 using Tapatalk

FYI: reception is 100%, ie full bar. Same sim card in a phone laying 10 cm away gives me top 4g+ speeds.
Installed 1.80.401.1 firmware and 4g works as it should (ICE rom)
Ever since the 1.80 line of software came the phone has felt slow at bootup and generaly not as fluid as on on 1.30. For instance, the animation on initial setup (rotating planet etc where you pick language) runs 100% smooth on 1.30 but on 1.80 and later, its lagging and stuttering.
it's quite weard if you ask me, why would a later software version run worse?

after a bit of investigating I can notice that the problem is the phone keeps switching cel tower.
It changes every second - it goes to close one with 4g+ and 5 bars, to another with 2 bars and 4g and up and down.
If i go to dialer and enter *#*#4636#*#* and then go to phone information and under "location" it says "CID = somenumbers". the numbers after CID are the cell tower.
It changes all the time. Phone never sticks to one.
Same sim card in a SGS6 or N5X gives me 100+ mbps 4g+ speed in the same location, but the HTC 10 is unable to stick to one tower and just keeps switching.
If i force 3G it will stay on one tower.

Exactly whats happening to me. Sometimes I also lose signal completely and phone will not downgrade to 3g. If i force it to 3g only, no problems at all. I hope its firmware related. I know someone who escalated the problem to htc and waiting for a response. I also notices that due to this problem my clock is sometimes off, as i have selected "use network provided time" under time settings.

Tip would be,as you're S-OFF downgrade firmware back to 1.80.401.1

Running 1.80.401.3 as well. Can't confirm this problem on my end. So I'd not be sure if it got anything to do with the latest firmware.

It seems the issue has to do with somr network operators. I travelled back to my home country and the only problem I faced was a weaker LTE signal but no drops in signal at all. But now where I am located i get both weak lte and drops in signal.
Sent from my HTC 10 using Tapatalk

I've had the same issue on 1.80.401.3 running Viper10 rom,network will always connect to HSPA,just downgraded firmware to 1.80.401.1 and it connects to 4G straight away

If i go inside (*#*#4636#*#*) menu and force LTE, it shows as connected to LTE/LTE+. But when i look inside the program, it see it change CID every second - it is constantly is doing this every second, sometimes it stay long enough for a speed test to start but it will generaly fail
This is only on some locations and esp where there is lte+, at my apartment with regular LTE it works just as good as any other device i have tested with. But at work i get 100+ mbps with a S6 or N5X, but the HTC refuse to get a solid fix on a tower - it keeps switching.

UPDATE: I installed the latest firmware (from maximus), 1.90.401.3. New radio or something fixed my problems with 4g!
Now i connect to 4g and 4g+ like it should and gives me around 100mbps download speeds, like on other devices.

Android 10 5g wifi keeps dropping

Hi guys
I'm using a wifi repeater Netgear EX8000. These days my wifi is very unstable even though it's full bar. The internet keeps dropping
I've tested it out with static IP on my phone setting and yet the wifi is still dropping fast.
Next to my test is my old phone Samsung S8+ where the wifi is stable without any drops. Both are connecting to the same 5G network. Both have the same Gateway, DNS. Only the static IPs are slightly different. This leads me to think Android 10 have bad wifi issues.
Anyone else having this problem?
If yes, how do you solve it? or do you downgrade back to android 9?

I was having wifi troubles, would be connected but nothing coming through. What helped me was in Wifi check the settings symbol in the network you are connected to and go to MAC address type and select "use device MAC" especially if you are trying static IP on your router.

Thx for the reply. I tried that but doesn't help for my case.

Have the same problem here. I don't have the 5g model and so far the only wifi drops I get are on 5ghz. I have not tested the 2.4ghz to see if it does the same thing.
So far usually restarting the wifi (toggle off and back on) fixes it. Dynamic/Static IP/metered/unmetered settings have no effect. I have no wifi control programs and wifi power saving settings are disabled. I do have mobile data on all the time.
As for downgrading it's what ever you want to do. IMHO this is one of those quirks that comes with a new OS update, and it isn't just Samsung devices that have been reported as having the same issue. I would presume that a subsequent update would probably contain a fix. Seeing as we just got an OS upgrade a factory data reset might be of more help then not.
I myself haven't done and FDR yet, but then again I am perfectly ok with toggling off and back on the wifi connection. I may end up doing a FDR at another point in time, or I might just make a tasker routine (restart wifi when no internet detected).

I have the same problem with Public wifi that require you to sign in...

Don't take this the wrong way, but your throughput speed issue is not the same as a WiFi disconnect issue.
Also SMB can be a fickle like that and effected by things if your just downloading to the phone or streaming a video, app support (CX File Explorer's SMB support), video file format/conversion via software... In your case I'm betting on non WiFi related issues since your attempting to stream pirated movies (saw that in your other thread) that probably are not converted for your phone and range in 11 to 14 gigs in size.

In the local area network, continuous transmission and playback, there is no problem with movie format. The software I use is CX File Explorer's and mxplayer.
The reason why this problem is because the previous S6 S7 NOTE8 does not have this problem

I myself haven't done and FDR yet, but then again I am perfectly ok with toggling off and back on the wifi connection. I may end up doing a FDR at another point in time, or I might just make a tasker routine (restart wifi when no internet detected).

I had ran a tasker routine to check for internet connection, and upon none in restarts the wifi on the phone.
I also ended up doing a factory data reset and set the phone back up (not using a backup) to resolve the issue. Avoiding the use of a backup means that any corrupted settings that were in my phone (that would have been backed up) did not get back into my phone. This maybe about the only solution to try.. another would be to try and different router (use a friends internet or something, so long as it's not the same router as yours). If the connection is stable on a different router then it maybe time to consider an upgrade to the wireless router your using.
Ultimately I ended up getting a wifi6 router and have not had a single problem at all. I also migrated away from using a private dns setting and use a dns block list with a vpn app. I am not sure if an update released to the phone (or a combination of things) fixed it or not, but it's working without issue.

I found this to work. I have been struggling with this issue for a while and found that it is a conflict with the wifi ip settings. The router changes ip configuration changes everyday for your protection. Change ip in wifi -- sprocket--advanced -- change from dhcp to static then save. Issue resolved.

I use a vpn that seems to do the trick.

Hello Everyone it is 4th of February 2021. I have an ONE PLUS 6 i started having an issue with my 5ghz wifi after the upgrade to android 10 almost 2 years ago . Anyhows it would drop the wifi randomly or dissconnect me from it and when i turned it on the 5ghz network it would take over a minute untill it connects. I have finally found A BIG solution to this problem it's the Security in your Modem. On my modem it was on security WPA-WPA2PSL-AUTO. Now i changed it to ONLY WPA2-PSK Or depending on your device which one works better if u have the option of WPA PSK either one of these u can choose them but dont go for WPA-WPA2PSL-AUTO. It's a security-Bug issue that popped up on many android 10 devices after the update. So once i changed it to either one of those instead of WPA-WPA2PSL-AUTO ' my issue went away. I've been struggling with this problem since the android 10 update came to my ONE PLUS 6 . So there you have it FINALLY A FIX TO OUR PROBLEM
