This is a very peculiar issue I'm encountering here. When I have only Wi-Fi enabled, everything seems to work fine. When mobile data is on, it drops when (re-)opening Pokémon GO and sometimes does that a few times until I get a stable connection. When both Wi-Fi and mobile data are on, the same thing happens.
I've seen a few complaints about this particular issue, but haven't seen a solution.
Running OP7T stock ROM, just rooted through Magisk. Error is reproducible almost every time.
Found a fix in setting the APN to "default" only. IPv4 was already set, but might have to be set too, according to some posts on the OP forum.
Leaving this here for anyone with similar issues.

Hi all
A search of the forums revealed 5 potential threads similar to this but not quite (not same symptom, phone, modem ...)
Keep loosing mobile data connection...
I have installed X-note 3 and found that my mobile internet is intermittent particularly in Youtube where I frequently have to click "No connection , Retry" or "Connection to Server lost, Retry" and in Play Store and Gmail where the problem tends to occur on a screen unlock after it has been unused for a few minutes - about 3 to 5 mins.
I dont believe this is a ROM issue because I d/l various ROMS such as Revolution, Alliance, PacMan, Paranoid and still I get the problem.
I tried installing all 9 of these radios here: http://forum.xda-developers.com/show....php?t=2044937 to no avail.
Also notice that if I set Network Mode to "GSM only" then this makes no difference to the problem (the default is "GSM/WCDMA Auto" which is what I've set it back to)
WiFi works fine.
Any ideas?
same issue here.
a lot of time trying to know why this happen. and i think it is due to fast dormancy.
the phone usually stays in standby in 3g... when you request some data it will automatically turn h or h+. Here is when you will notice the internet moving.
But unfortunately if you have some.coverage issues you can have this problem and then the programs instantly report no conection. If you insist you will see you can obtain connection. 5 seconds later 3g will appear again
It does not mind you will see the bars of coverage at maximum... if there is no quality signal you will have this problem.
I just have this problem at work. Not in other places.
But if you want a constant connection I recommend to keep for example online music while navigating...this will avoid the issue...unfortunately you will increase your data plan..
Yes!! This is exactly what happens.
So it can't be my specific phone but perhaps a hardware design or software issue. I don't recall this I happening before I rooted
Weird
Fixed it - so far at least
Fast Dormancy is the problem. It was enabled by default and I have turned this off. The connection is now fine and seems to be "always on". For me this is okay because I do not have any data limits or pay per MB for data. I do notice that new connections take a little longer to start (for example, time taken to access internet when opening up an app that is not currently running) . This is not noticeable for apps already running (in the background)
This explains ....

I have a peculiar WiFi issue in my office where I can connect to the router, however, I immediately receive a message: "internet unavailable". I am using latest stock T-Mobile ROM. 5.01, Build 20E. Other phones have no problem like my Nexus 5 or other people's iphones. Also, I am running a dualboot partition with a nightly on the same phone and it works fine in Cyagenomod.
I've tried this app: WiFi Doctor, and it finally worked until I went out of the office for a few minutes. When I came back I was at square one and what's worse, WiFi Doctor couldn't cure it any longer.
Anyone? Hello? I'm pretty sure there are a few smart people out there.
T-Mobile G3 stock ROM, Android 4.4.2, build D85110m, encountered the same problem in my office. Likewise, no issue with an old Samsung or iPhones.
From what I've manged to find on the internet, IPv6 or the MTU setting might be a contributing factor.
This isn't a fix per se, but voodoo steps of forgetting the network, switching off wifi, switching on wifi, re-connecting to network (staying on the Wi-Fi screen and waiting to see that it connects) works sometimes. Sometimes it fails and tries to re-obtain an ip address and it works after it re-tries several times. All this while I would be on the Wi-Fi screen watching it.
Occasionally, rebooting the phone helped for a while.
All the boxes under Advanced Wi-Fi are unchecked for me.
My G3 is not rooted, so I've not tested to see if disabling IPv6 or changing MTU fixes it. If you (or anybody else) do test it, I'd appreciate it if you could post your results.
On different (clean) stock roms, both mm and ll, data doesn't work when I leave my wifi's range. I have to toggle airplane mode to get it to work again. Tried "switch automatically" in wifi settings and "aggressive handover" in developer section. I found g2 and g3 owners with 6th same issue, but u don't find a proper solution, besides managing this using tasker. The issue appeared suddenly and persists on every rom I try. H815
Snap.
Have the same problem with mine.
It seems to eventually pick up data, but this could be anything from 5-30 minutes are leaving the WiFi connection.
Airplane mode on/off fixes it sometimes, but others I have restarted the phone with no change.
Anyone have any ideas how to fix this?
LG G4 H815.
Android 6.0.
Software version V20g-EUR-XX.
Same issue here, which started suddenly with no obvious reason.
Anyone?
In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!
Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?
Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.

It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).
UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
Hey, I'm new on the Xiaomi Mi 9 SE and experienced some issues with the (not present) mobile data connection..I'm on T-Mobile in Germany with 4G but barely get any connection. If I'm turning off mobile data and on again it works for a short moment and then falls back to no connection. You can watch this in the Google Drive Video: Link.
I've tried nearly everthing, except wiping the device (I restored apps and settings from my old phone, could this be the fault?). Adjusting APN doesn't work, I tried every setting for mobile network, nothing solved this problem. There some other reddit users with similar problems, but they are old and solved by an update. Has anyone an idea what I could do?
