[Q] Wifi Sharing on Tmobile Woes

I run CM7 nightlies on my Tmobile N1. Recently I killed my cable Internet/TV connection at home and have been using the built in WiFi tether for my home devices.
While it typically works great (for free), the data on my N1 will lock up. I have full 3G/HSDPA at my house. Using #*#*4636*#*# it states I am connected but fails to ping or load up any data on the phone or through its shared connection.
The only way to fix the problem is to toggle airplane mode and re-enable the WiFi Tether or sometimes a reset is required.
I've changed to several Gingerbread roms, flashed various radios, and even exchanged SIM cards.
Is this behavior normal or not? For regular web surfing I can live with it, but the main problem is that I cannot download anything without it getting interrupted (like updated nightlies or 50mb+ files).

No one has any problems with their WiFi sharing?

i used my phones internet as my regular home internet for a month. i used up about 25 gigs. i streamed videos, downloaded videos and podcasts with no interruptions. don't know what your problem could be. i was using cyan 6.1.1

I occasionally have experienced that issue, but it seems as if you have it much more frequently than I ever did. I would mainly get it when I tethered from areas with bad reception.
You state that you have full 3G/HSPA at your house. I am wondering how many bars of reception you happen to have. Also, try setting your phone to WCDMA Only in that 4636 menu. That seemed to decrease the frequency at which it happened for me.
I also found that once in a while, I could get tethered data working again by simply using the phone's native web browser to access any data. Good luck with the issue.

I typically have full bars of signal usually reading around -100dbm. When the internet drops, it drops completely; maps, browser, apps, etc all fail and I can't "jump start" it other then toggling airplane mode or resetting the phone. Typically a reset is best.
Perhaps I'll flash back to CM 6.1 and test it over the weekend. I'll do a backup of my current setup if things aren't fixed.
The purpose of this thread was simply to see if others have experienced the same issues and if it was worth "trying" to fix.

It might be a case of overheating device - it'll be good to test different ROMs and kernels.

I don't think the device is over heating at all rather then just a carrier issue. I flashed to CM 6.1.1 over the weekend and immediately found I was still having data issues (where it would work for like 5 minutes then drop out).
I did find that EDGE was a solid connection and stayed connected while I downloaded CM7 and GAPPS. I put a call into Tmobile and yacked at them for several hours. They escalated it up several times in their engineering department and so we'll see. I spoke to HTC a few times in there and they didn't think it was a handset problem either.
I guess we can close this thread as it doesn't seem to be a wide spread problem. I am running a stable version of CM7 now and we'll see.
@above: I have tested different radios, roms, and kernels. This thread started out as a issue with WiFi Tethering but ended up being the phone simply dropping its data connection. I originally was curious if this wifi sharing behavior was normal or not.

[Q] Wifi problems with multiple router networks

I seem to be having pretty severe wifi issues on networks that are composed of a large number of routers (i.e. campus/business networks) where going between routers will result in the phone believing it is connected, but not being able to send/receive data. This is evidenced both by the lack of notifications/apps working, as well as the wifi icon in the quick toggle panel being orange (which indicates no data being sent/recieved, I believe) despite having full signal. This means that without any external indication that anything is wrong, my phone essentially does not work anymore until I turn the wifi off and back on. Previous phones (galaxy nexus, droid) as well as computers did not have this issue on the same network.
Has anyone else noticed this problem, and if so, found any way to get around it other than remembering to reset the wifi power every time you move between areas?

It sounds like there are multiple WAPs all using the same SSID, and Android is not requesting a new IP address when it disconnects from one WAP and connects to another. You could probably work around the issue using Tasker, and have it toggle Wifi off and on again any time Wifi is disconnected. I you go that route I would recommend using the trial version available from the developer's site, or one of the many similar apps that are available in the Play Store for free.
There may be something more to this though. Hopefully someone else has another idea.

I'm having the same issues both out in public and at my home. This issue didn't seem to exist prior to 4.4 update. Now I'm constantly having to toggle my WiFi on and off or toggle airplane mode and also hitting the symbol down at the bottom left on my phone and on my router at the same time. If someone has any information to correct this would be great. Like I said I never had this problem prior to 4.4.

Thanks for the suggestion! One question though: does the wifi actually "disconnect" when there is a handover between two routers of the same network? Is a handover while constantly connected something tasker could detect?

As far as I know, Android doesn't "roam" seamlessly from one AP to another even when the SSIDs are the same. I'm pretty sure Tasker would see this as Wifi being disconnected (albeit briefly). You could then tell Tasker to turn off Wifi for 5 seconds and then turn it back on again.

I finally got around to making a tasker script to do this, and tried it out for a few days, but unfortunately it does not seem to detect the changing between the different routers on my institute network as having the wifi disconnected, and thus doesn't solve the issue. It was a good idea to try though!
I've cross-posted the issue at the link below in hope motorola will see this, but if anyone knows a better way to report this, please let me know.

Issues with wife's Turbo

My wife and I both have the Turbo on VZW (joint plan, etc). I generally perform any mods on my phone first, before doing the same to hers, so that I know what issues will happen and I can make sure the phone doesn't work any differently for her daily usage. So, aside from apps, we have the same phone in theory. Both phones are stock SU4TL-44, rooted, BL-unlocked (via Sunshine) states.
My wife's has been having rather poor battery life for the past many months. I can get a good 3.5+ hours of screen-on-time on my phone (as reported by GSam) but hers only gets like 1.5 hours on a good day. Her phone radio is what's reported as the largest load, so I started trying things there. We were both on the .49 radio (using the TWRP download by firstEncounter), so I thought maybe her phone doesn't like that radio, and put her back to the .44 radio. (Note, I have checked the hashes on these files, and they match. I also have used the same-exact files on both phones (via dropbox)... so it shouldn't be a radio/corruption issue.) Both
I'm not sure if the battery life has improved or not (only been a few days, but checking just now it looks like her max is now 2.5 hours in GSam, so that's a start I guess) but now another problem has come up - her phone keeps dropping the internet connection. Wifi appears to remain connected, but it shows an "!" which means it has lost internet connectivity. Checking the browser confirms that it is really lost for internet sites. (Next time, I plan to try going to the router IP and seeing if I can get to that, at least...) This drop happens sporadically, and doesn't self-repair... it is only fixed by disabling and then re-enabling Wifi. I "forgot" the wifi (2.4GHz, by the way), re-connected, and re-entered the password... this doesn't seem to fix the dropout either.
The wifi, itself, is working well. My Turbo has none of these issues, my work phone (Turbo2) doesn't appear to have issues, nor do our 2 laptops or wifi-Tivo... every other device works fine, just her phone has been giving issues.
Needless to say, the priority is to fix the dropping internet connectivity... if anyone can help me troubleshoot this further, I would appreciate it.
Longer term, I'd like to figure out the battery issues (health is reported as "good" by various battery apps... is there a way to see what the "real" capacity is, and not just "good/bad"?)... but the wifi is the primary issue. Part of me thinks of doing a factory reset (or maybe flashing SU4TL-49 and then re-rooting)... but I fear this may not fix anything.
Any help/ideas are appreciated. Thank you!
EDIT: One more difference - she has a Tile Gen2 along with the associated app. The app requires Bluetooth to be on, as it does some polling, I expect. I have turned this off for now (further testing) to see if it helps. She's had the Tile for a while, so it's not a new change... but I'm running out of ideas. Battery usage isn't significant, based on what's reported... but I thought maybe it has some effect on the wifi... I simply don't know, so I'm trying anything!

A little more info. I have left her bluetooth off for the past day, thinking that maybe Tile was the problem... it certainly seems to have helped the battery life (weird, since all the battery tools I've used don't seem to identify the app or BT as a large battery sink?)
Things were great for about 24 hours, but now the dreaded exclamation point is back. I tried getting to the router, but I get "ERR_ADDRESS_UNREACHABLE" from Chrome. Weird since I'm giving it an actual IP address (so no DNS should be involved). Phone has a valid IP address (same one it's had for a while now) and claims to have the interface "up" as well.
Any ideas, anyone?
EDIT: I see some UPNP activity in my router... I wonder if that has something to do with it. As a test, I have disabled UPNP to see if that helps (and what it breaks... which shouldn't be much, as I try to keep things explicitly configured)....

A further update in case others run into problems like this.... the issue may be caused by an interaction between my router and the bluetooth Tile app (which isn't on my phone but uses BT relatively often) - note that BT runs on the same 2.4GHz frequency as her wifi. I chose 2.4Ghz wifi (instead of 5Ghz) on her phone because it helps extend the range. Turning off BT on her phone seems to keep the connection stable and without issue... I have a little more testing to do to ensure it's the root cause before I consider it found.
There are a few potential solutions. One is to update the firmware on the router to a newer one which has an option to enable BT coexistence mode (disables some features in 2.4GHz wifi to improve compatibility). Another is to move her to 5GHz. I plan to test the coexistence mode, just to prove it's the problem... but my final solution will likely be to move her to 5GHz as the coexistence mode may reduce performance on 2.4GHz.

What about changing Wi-Fi channels on the router?
I also disable 5GHz on both our Quarks because the 5GHz range is shorter. I set our phones to ONLY connect to 2.4GHz and that's what I use for Wi-Fi router too (even routers with dual bands, I disable the 5GHz band).
But you can change 2.4GHz Wi-Fi router channels to mitigate interference, right?
http://www.goldtouch.com/stop-bluetooth-interference-messing-devices/
How to Stop Bluetooth Interference From Messing With Your Other Devices
Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel — specifically, a different channel than the one your Bluetooth devices are using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

I don't use anything Apple -- I just quoted from that article because it suggested what I was suggesting, changing Wi-Fi channels...

Yeah, I kept testing and found that the BT wasn't the only issue (may have been part of it, but it still dropped internet after a day or two even when BT was off).
Like you said, it's probably a 2.4GHz interference issue... and since I'm in an apartment building the spectrum is rather crowded. Plus, if anyone else bought a new phone/monitor/microwave/router that could be causing the issue, too. Bottom line, there's too much out of my control, so I switched her back onto 5GHz and the problem seems to have gone away (at least for the past few days)... so I'll leave it at that. I can't solve the entire area's problem, after all!
I am on the "cleanest" channel I can find, but that's only based on seeing other routers (via Wifi Analyzer)... interference won't be "seen" there, so we can only guess on those issues.
Bottom line, switching her phone to 5GHz is good enough for now, and solves the issue. I'll flip her phone back to the 49 radio as well.
In fact, this might have also helped her battery issue - when the phone lost internet, it would sit there and suck down power for "phone radio" doing who-knows-what. I don't see why it should do that, but it really killed the battery on one of the days. Putting her on 5Ghz prevents the loss of internet, and the battery drain from that, too... so that's better. Still, she gets much less SOT than I do on my phone, and she uses it less than I do... maybe the battery just needs to be replaced after all.
I wish there was a way to see what the "real capacity" is of the battery, instead of just assuming that 100% = original capacity (which we know it won't be). Do you know of a way to get that info?

Dodgy wifi

Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.

No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..

Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835

I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)

I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.

I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.

Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.

Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.

no problem here conecting to 5 and 2.4 wifis...

So far my wifi has been fine...

Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.

Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!

exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.

I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.

I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?

wifi dropping constantly

Any help appreciated, WiFi is dropping constantly for me. Only at home works fine while at my job and connected there. But at home WiFi is unusable. I have to use data. No other device on the WiFi has this issue. Issue is on every ROM I've tried. Here's a log if it helps but I'm out of ideas. Tried forgetting the network and rejoining multiple times but has not worked

Clearly an incompatibility between your home wifi and your phone, but I'm not smart enough to say what it is. You'll need to play around with wifi settings on your access point, and see if anything helps.
Some thoughts:
Your phone seems to be trying to connect to two nets, "living room TV" and "catch me outside". Try switching one of them off.
Your problem might be related to this post by @frov2017:
https://forum.xda-developers.com/nexus-7/help/connect-to-wifi-t3606319/post72575674
You log mentions Australia and America. It's important that your phone and your wifi is set to the same country, because different frequencies are allowed in different countries.
