[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.

[Q] ATT S6 bootloops when near unsecured WiFi

Just got my S6 yesterday. I noticed that if WiFi is on but not connected and if there is an unsecured WiFi my phone will try to automatically connect to it and then start a bootloop process. If I park near a McDonalds or in a neighborhood it happens. Everything is fine with WiFi off. There is a minute before the WiFi auto connects and I can turn the WiFi off and that is the only way to stop the loops.
Any thoughts?

Based on how new the phone is, I'd have AT&T replace it with a new unit now and see if it's still happening. There's no excuse for that to happen on brand new hardware, but maybe it is a design flaw... confirm it with a replacement.

Did you Disable some Wifi / Hotspot / Smart WiFi related stock app?
There is an option in the WiFi settings about auto-connecting, you might try turning it off. My guess is you have "Auto Connect to AT&T Hotspots" turned on, but the Smart WiFi / Hotspot application disabled, so it is failing.

Yeah I tried turning all the att auto connect off and google location scans. I also factory restored it.
Can someone with an att varient try it and let me know? I don't want a hassle to return it if it's a software error on other units too.

I was googling around and found this thread, I am having the EXACT same problem with my AT&T S6

Signal issues?

Is anyone having signal issues with the axon pro? My phone keeps going in and out of signal, and while my status bar says that I have "no service" I will have full bars, but only when connected to WiFi. When not connected to WiFi, all the bars are lost.
Is anyone else experiencing these signal issues or bug of this sort? Just trying to determine the root of the problem.

When did you start having problems? After the latest update?
I think it is a problem with the Wifi calling feature. After trying wifi calling and having problems (the other person couldn't hear me), I decided to turn it off.
After turning it off I started having crazy issues - the wifi calling would turn on even though I had turned it off. After turning off wifi completely, data wouldn't work so I rebooted the phone. After rebooting the phone, I couldn't get a signal at all. I tried rebooting the phone multiple times but the signal wouldn't come back. I switched SIMs and it still wouldn't work. At this point I was thinking there was a hardware problem with the phone so I was considering calling ZTE to get a new one. But I tried one last thing - I turned wifi back on and made a wifi call - the signal came back! So it is a software problem.
So I turned on wifi calling again but configured for "cellular preferred". It seemed to work well for a while, but then a few days later went crazy notifying me every few seconds that wifi calling was turning on/turning off.
To keep the phone stable I have now unfortunately had to setup the phone with "Wifi Calling Preferred". Thankfully soon after I did this I started getting error "REG09: Missing 911 address" so it doesn't try to use wifi calling anymore.
No point calling ZTE support because their phone support is appallingly bad. They won't understand the issue, they won't give me a ticket number. All they will say is either "reset the phone" or try to send me a new phone which will just make me lose time and lose data. They had a website where you could raise tickets for a little while...but it looks like it has been blocked now as it could have been too useful .

Trying posting to their Twitter account and report the issue, that is how i got their attention. Also when you call them (here in the USA) tell them that you have already done a reset on your phone and that did not resolve the issue!!!

I got some signal issues too I only get 2 to 3 tower usually but at time its completely dead and until I reboot my phone signal doesn't Pop up ...and at times even though I have like 2 signal tower it shows emergency calls oly...I don't use WiFi calling as am on straight talk.but the WiFi calling feature suddenly pops up in the notification bar giving an error message u can't swipe that off the notification bar too u gotta go to MORE in settings and switch on and switch off the WiFi calling feature to remove the error msg from the notification bar .
Signal keeps fluctuating call clarity is a lil bit poor comparing it to my old lg g2 . macro focus doesn't work at all u can't focus a thing that's really close in auto. I dono what to do with this phone.it just doesn't satisfy the basic need of a phone voice calls and message(messages take a long time to send ).

Again, not worth my breath. If you check the new thread someone called up ZTE about the issue and they blamed it on T-Mobile (which is complete and utter BS). When I called about the camera issues they tried to blame it on Google. Why waste my time to be told lies? The support is completely s***.

Well hopefully ZTE will come out with a fix really soon, I don't think that they want to lose the users they have.......

Loss of at&t signal
In one location that I frequent I always sit there without a cellular signal while people around me are using their cell phones

LTE signal strength sporadic
My Pro shows a few bars for a couple seconds,then NO SIGNAL for a few seconds. ZTE is not fixing this problem? It has been going on since January. Now is September.

For those with this issue, does a factory reset change this behavior, or at least the frequency of it?

wi-fi calling preferences updated

Ever since I updated my Note 9 (Tmobile, stock OS) to Pie, I get the "wi-fi calling preferences updated" message numerous times throughout the day. There is no longer an icon in the status bar when Wifi calling is connected. The network switches even when I am on a call (and the call drops).
Are there others here having this issue? T Mobile staff appear to be surprised at this happening (though on their forum there are several threads about this with no solution). Any help will be much appreciated. Thanks!

I am having exactly the same issue, I really hope there is a solution to this because it's causing me tremendous connection issues when I am on my call.

would that be normal if on the go the location changes? just spitballin

using a system that has been updated versus starting from scratch on that new OS version is bound to cause issues. forum is riddled with users having weird issues post pie upgrade.
do your selves a favour and factory wipe and be done with it.

Your device is supposed to switch during a call to help keep the call going. You'll hear a beep which signifies your wifi signal is getting too weak to maintain the call. If you have a network connection, the device will switch to it, but if you're in a building where the is none, it will drop the call unless you stay within range of the wifi.
I went ahead and just adjusted the notification settings so that it doesn't even bother popping up. I think the wifi calling icon thing might be a Android Pie issue with Google knocking out certain permission allowances. I will have to do some digging into that.

I have, and have had for a long time, this very issue. I have had it over a few phones and Android versions. T-mobile is pushing down a change to 'WiFi Calling Preference' setting changing it to Cellular preferred. T-Mobile denies it but I have screen shots of the notification when they do it.
This is a problem for me since I rely heavily on WiFi calling with marginal cell signal strength. I am about to leave TMobile because of it.

Pixel 5 wi-fi calling on 3UK

Hi,
I'm seriously considering getting a good refurbished Pixel 5, but I would like to know if it's possible to set wi-fi calling preferences on 3UK.
To explain, I live in an area with very spotty cellular coverage so WiFi calling is a must have, but unless I can set the phone to prefer WiFi calling over cellular calling, I have to put my phone into airplane mode in my house because there is just enough cellular signal strength to prevent the phone from automatically using wi-fi for calls. Failure to use airplane mode results in many dropped calls because the signal isn't strong enough to support the call.
Any assistance gratefully received.
Thanks

So it's possible to set the preferences to use Wi-fi calling whenever there's a wi-fi connection, even if there's a weak cellular signal?
This is on the UK 3 network?
Thanks

It'll give you the option whether there's WiFi or not. It's either on or off.
Yes, 3uk

Thanks, but I don't think I explained my question very well.
What I'm wondering is, when you turn wi-fi calling on, is there another setting to prefer calling via wi-fi, or calling via cellular?
Cheers for your help.

I know this may not be what you're looking for but it may help..
I am on Pixel 5 Android 12L stock ROM
When turning WIFI Calling on, you get this menu option.
I'm imagining if have WIFI Calling options, then the menus would be the same, being the same phone/firmware.
But I obviously can't confirm.

Thanks!
That's exactly what I was looking for.
Which network are you on?

Just a shot in the dark, but changing your default language to US English might work. Here in Canada I had to do that to get "Hold for Me" working

Thanks for the suggestion but I think the availability of the wi-fi calling preferences options are based on the mobile network.
I'm currently using a Samsung Galaxy S20FE because it has Bixby Routines, which lets me disable the cellular radios when the phone connects to my home WiFi network. Obviously, this isn't as elegant as allowing me to set a wi-fi calling preference.
The point is that this is a dual SIM phone - I've noticed that it offers wi-fi calling preferences for my O2 UK SIM but not for my 3UK SIM.
I don't think I'm going to get any luck with this unless I change network.
Thanks to all for your assistance.

Very interesting.
Now I don't use it, I should start looking into it, but I just don't have any uses off the top of my head, like what I foresee could work to your advantage.
Instead of Bixby, why not give tasker a try? It should be able to allow you to do what Bixby does and probably more.
You should def. be able to set up a Tasker "Routine" that allow you to disable the cellular radio when you connect to WIFI network, and maybe even a Tasker for setting the WIFI calling preference?
I wish you the best of luck with everything!

I actually tried Tasker first (I've used it many times over the years) but it isn't able to toggle Airplane mode without having to either root the phone or grant specific permissions via ADB (each time the phone is rebooted).
In case you are wondering, I have configured Airplane mode to leave WiFi and Bluetooth untouched, so it actually only toggles the cellular radio on and off.
Since Bixby Routines are "baked in" on Galaxy devices, it has no restrictions on setting Airplane mode on/off. Obviously, this solution is only available on Galaxy devices, which is why I'm using this S20FE 5G as my daily driver at the moment.
With any other devices, I have to remember to turn airplane mode on when I'm at home to force wi-fi calling. The problem is that I often forget to turn airplane mode off again when I'm out and about.
Thanks again to everyone for your help and suggestions.
