T280 WiFi keps shutting down and restarting - Samsung Galaxy Tab A series Questions & Answers

Had this problem for a while, don't think it happened when new before I started messing with rooting. The tablet looses contection with WiFi then quickly reconnects. I have my modem set to a channel. It's annoying to me, do I need to change a setting? I've looked at WiFi settings.

Connection Dropping :(

Hi there
First time poster, shame it has to be a cry for help!!
I've got the touch HD, and I love it, however over the last week or so its started losing its HDSPA and 3G connection and dropping to phone only. At first I thought this maybe network related (T-Mobile), however it seems to do it in all locations.
I'ver noticed when it does it, the data connection slider in the settings tab, is switched to off, and as soon as I flick it back on, it picks up the signal fine (only to lose it again after a random amount of time). I've downloaded Tweak HD and set the internet to always on, however that doesn't make a difference.
I've not installed any custom roms, its the factory build, really hope someone can help
Thank you
Do you see the connection drop while the screen is on or is it after you have put the phone in standby (screen off)?
It seems to be random, I can be halfway through browsing the web and it'll drop or just coming out of standy.
The most common time seems to be when I do a send/receive on the email tab, it shows the 'H' icon then as soon as it starts syncronising, it drops out to radio then I have te re-send to get it to connect again.
I seem to recall the same thing happening to me back when I was using the stock rom. For the first week everything was fine, then the connection would drop when I turned the screen off or even when the phone was on. If you've tried setting the connection to "always on" and that does not fix the problem, then I would next try and download Schaps Advanced Config and enable/disable the different power management settings. I've suggested this to a few others for disconnect problems in standby and it seemed to work.

Bell JK4 - Wi-Fi Discussion

After upgrading to JK4 via Kies I've noticed some strange Wi-Fi behaviour. It seems to manifest at different times and for no apparent reason, so I'm starting a thread to see if a) anyone else has this issue and b) if so, how does it manifest for them.
First manifestation: after turning on Wi-Fi through Notifications the text switched to "On" but the Wi-Fi symbol did not turn green. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was showing "Error". A reboot of the phone fixed it, temporarily.
Second manifestation: after turning on Wi-Fi through Notifications the text switched to "On" and the Wi-Fi symbol turned green, but it did not connect to my wireless network automatically like it should. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was rapidly switching from a "Turning on" state to "Turning off". It did this about 10-15 times in a few seconds then went to "Error". Turning on and off the Wi-Fi again solved this issue.
Every time I solve this it seems to come back within a 24 hour period. I didn't have this problem (from what I can see) on JK3. I factory reset before and after flashing to JK4, and I flashed JH2 back just to be on the safe side beforehand.
Let the discussion begin!

I quickly tried out after reading your post, and I did confirm your first issue happening, but only when I turn my Wi-Fi on and off really quickly. Also my phone didn't lock up as you described either. Basically, I could only make that issue to surface once I turn off the Wi-Fi, and then turn it back on as soon as my phone reports it is disconnected. When I go into Wi-Fi settings, it does say "Error" there, but if I check the "Wi-Fi" there again, it connects automatically.
I almost never use Wi-Fi because I get 6GB of data, but I can see this becoming a very annoying issue if you have to use Wi-Fi frequently.
Edit: Actually, I ran into a different issue just now. I kept on playing around with my Wi-Fi, and confirmed this happening: Wi-Fi text turns to "ON" but the icon doesn't turn green. When I go into settings, it says "Turning Wi-Fi On.." or something similar and is stuck there. I wasn't able to turn on nor off the Wi-Fi. Reboot fixed issue...for now I guess.
I have also had this issue but I believe it has to do with trying to turn on wireless when your preferred network has a very weak signal. When I'm next to my router, I can turn wi-fi on and off rapidly with no issues. I have only had the issue in my room which has a much weaker signal.

i was having problems with my wifi today...i wasnt able to pickup any wifi signals and i couldnt manually turn the wifi on either...i got a few force closes on some apps and decided to reboot the phone, hopefully sovling the problem...instead i got stuck in the boot loop at the i9000m logo and now my internal sd card is done....hopefully i can return this pos at bell(im on rogers) and do a hup through rogers for the iphone4...at least thats a stable device.

I've never tested right beside the router, but my room is next to the room which has the router so I would think I'd have a fairly strong signal.
Interesting, though...

I tested my Wi-Fi pretty much right beside my router as well...like less than 3 feet away. My phone was reporting it was seeing an "excellent" signal.

I find my wifi on my phone to be pretty solid.
I have an occasional issue where it does not see my wifi router at work, but all I do is turn it off / on and off she does. Just happens with the work router. Never had an issue with my linksys at home.
I've experience this issue with JH2 and it was caused by a change to fast in the settings. Just give your phone some time to connect and get identified on the network before you turn it off ans don't torn it on right after you disconnect it and you should be fine.
Been having the same issues since upgrading to JK4. Wifi gets stuck in "enabling" state occasionally when it try to turn it on. Sometimes I have to go as far as restarting the phone to get it to work again. Not a huge deal but still a nuisance.
I have seen both of these situations occur once after applying JK3 from Odin. It was shortly after booting it up for the first time including the "ERROR" text. I attributed it to a one-time glitch and it has not come back since. When I am home I force WiFi on and leave it in that state until I leave the house for work the following day so I am not constantly messing with the settings.
I get a similar issue butt only when activating my mobile AP.

I've been having a similar issue with my wifi since upgrading to JK4. I've gotten the "error" message on enabling wifi, but as others have mentioned it may be because I'm re-enabling it too quickly after turning it off. However, in one instance yesterday I tried re-enabling it several times after turning it off via the control widget and was ultimately forced to reboot before it worked again. Also, this morning I found that after leaving home and coming to work, I was still only seeing the wifi hotspots near my apartment rather than the ones in my new location (one of which I have saved and automatically connect to). I had to reset the wifi to find the local hotspots. Other than these wifi issues, I'm really loving JK4 so I just hope they get sorted out.

WiFi turning on by itself

Hi,
My H990DS has been bothering me for a couple of days as WiFi turns itself on without any kind of intervention.
Turning it off manually or having the phone restart does not help. I made sure the latest apps installed make no impact.
Playing with Developer Options made no difference.
I am ready to Factory Data reset.
Anyone experienced something similar ?
Thanks,
My 918 always shows wifi active in GSAM's graph, even when set to "Never" under the "Wifi on while inactive" option in system settings. I ended up just downloading Leandroid from the play store and setting it to disable the wifi radio, and renable it periodically to check for push messages. Seems to work fine with doze and standby time has improved.
Under settings, location, three dots top right, scanning, turn wifi scanning off. It turns back on anytime you use wifi and you manually have to turn it back off each time.
Mine (918) does this all the time. Im thinking its a 7.0 thing. There has been a few exceptions where it has stayed off. In my case I drive through a busy section in town and it constantly connects to the 20 or so open wifi spots so I turn it off. Well once I pull into the garage at home its magically back on.
Maybe something to do with networks it recognizes, Xfinity wifi wreaks havoc on it as well.
As soon as I uninstalled the latest apps, the issue disappeared. Not a single exception in 24 hours.
I suspect a Sip Client had caused the problem.

What!?
That sounds utterly horific for the battery, nevermind privacy concerns. I thankfully haven't experienced anything similar myself, but I've only ever used custom ROMs so perhaps that's the cause. But that sounds terrible.

wifi seemingly ignores "keep wifi active on sleep" setting

has anyone else seen this with stock OOS? when i pick my phone up after not using it for a while, almost every single time it can't connect to anything until the screen is on for a few seconds...as if it's needing to reconnect to the wifi. after a few seconds, everything is fine (as if it had finished connecting and now works). i have it set to keep wifi on during sleep, but it seems to be ignoring that setting...at least that's the only thing i can figure as to what's going on. i'm stock unrooted on oos 4.5.15.
is there anything i can do here? i love this phone in every way EXCEPT for the god-awful wifi performance. the wifi in general has gotten much better, but this one bug in particular is incredibly annoying...also, before someone mentions it, i've already changed my router out trying to fix this. i was having other wifi issues, so i upgraded to ubiquiti gear...hasn't resolved this particular issue.
edit: of note, i've also tried turning doze off to help fix this...but doze mode in general on this phone seems completely unreliable in pretty much every way. that didn't help fix anything either.

Wifi connectivity issues

All day today I have been having Wi-Fi connectivity issues. None of the other devices in my home are experiencing this. It is just my OnePlus 8 Pro that keeps dropping Wi-Fi and refuses to load games. While I'm on Facebook or any other app it refuses to load. It doesn't matter what frequency I am on or what channel I am on. It is not my service provider I have already called and asked. I think something is messed up. So is anyone else having Wi-Fi problems on the OnePlus 8 Pro?
Do you have a private DNS active?
Same here

Mine will only stay connected for short periods. If I put it down and leave it for a while 9 times out of 10 it's swapped me back to mobile data. I've reached out to OnePlus to see if it's a fault or a known problem they're working on.
This is actually happening to me as well. 10.5.8 stock rooted. I see that exclamation point next to the wifi signal sometimes and nothing else in the house is having issues.
Okay so this is what you have to do to fix the problem. Click onto your Wi-Fi and let it go into the settings then swipe up on your screen and go into the app info. Clear your cache. Turn your Wi-Fi off and back on and it should work just fine
I have a much better fix. Change your MAC privacy setting to "Use device MAC" and change from default "Use randomized MAC". Wa la I haven't had a drop all day. This has been driving me crazy!
It might actually be a really simple problem with a simple solution, just i need to see a screenshot with the diagnostics, or the troubleshoot from the device why doesn't it want to keep the connection steady. You can actually learn all these things related to the wifi and some little programming things really easily, it is not that tough, trust me. I took the cisco programming course from SPOTOclub.com, during this pandemic, and in one month i was already an expert in the wireless connection and the LAN and so on and so forth.
If you're having Wi-Fi connection problems or see an Wi-Fi icon with an exclamation point Wi-Fi problem, try the solutions below:
Make sure Wi-Fi is on. Then turn it off and on again to reconnect.
Make sure Airplane mode is off. Then turn it on and off again to reconnect.
Press your phone's power button for a few seconds. Then, on your screen, tap Restart Restart.If you don't see "Restart," press and hold the power button for about 30 seconds, until your phone restarts.
