WiFi *profile* keeps getting disabled?

I've noticed that the profile for my home wifi network keeps getting disabled. Usually, I'll leave for a bit, then come back and about half the time it never reconnects. When I go into the wifi list, it's marked as disabled. I enable it and it works fine from that point unless I leave again. It's my understanding a profile will get disabled when it cannot connect to a network for some reason, but clearly it can. My G2 and SGS never have this problem. Is this a setting somewhere? Thanks...

I am having this same issue. I dont know how to fix it

This is more serious than I realized! I just got disconnected randomly even while staying in perfect coverage. Not only does it disconnect, but it DISABLES the connection and won't reconnect again unless I manually tell it to. I rely 100% on WiFi calling while home and now I'm missing all kinds of calls and texts because WiFi is disconnected...
I'm hoping this is just is a software issue that can be resolved pretty quickly, officially or unofficially...

This phone has like 10 legit problems already. Tmobile needs to hurry up with the updates or the refunds will kill them.

It might help if you talk about the router you're using. I have a Netgear N600 and haven't had any Wi-Fi issues either connecting, staying connected, or automatically reconnecting. Bluetooth on the other hand...

It's a Linksys WRT610N. Very modern and very stable router. There's no reason this phone should have any problem with it. I literally have a G2 and SGS sitting side-by-side with the G2x and only the G2x has this problem. The SGS is Froyo and the G2 is Gingerbread. I also have a slew of other wireless (on both 2.4ghz and 5.8ghz bands) and wired clients connected that all have zero issues. I don't know why it would work on one router and not the next...
Are you using WPA2-AES encryption or something else?

Yes. And you're right, the phone is very temperamental across a number of areas.

Did you set up your wifi to never go to sleep? Cause if you havent - it disconnects every time you turn off the screen.
In order to do that, go to Settings=>Wireless & Networks=>Wi-Fi Settings=> click on the "menu" button on your phone=> Advanced=> Wi-Fi sleep policy=> and choose Never.
I did that, and my wifi calling is flawless ... and I rely on it pretty much all the time that I am at home (thanks for that stupid t-mobile signal)

I have the same issue and the setting I have by default to Never go to sleep... Also, has nothing to do with router as any of my other phones have this issue including Nexus One.

Did by any chance any of you with this issue restore some Titanium Back-ups? Because when I restored mine from a back-up of my 1st G2x (exchanged) I also restored the previous wi-fi settings and after that the wi-fi wouldn't work correctly. I did a factory reset and it fixed the problem.
Edit: If all else fails, then try a factory reset. I know it sucks, but it could fix everything.

I'm having issues with this as well. Wifi set to never sleep, I haven't restored any apps. I constantly lose connection. I've tried the factory reset thing etc. and it doesn't help.

I can connect to my wireless g Linksys access point but not my airport extreme ... my Linksys is open my ape is not(I realize I wrote ape LOL)

WiFi seems to be losing dns services
I have the same WiFi problems and while a factory reset clears the problem
temporarily and changing the WiFi sleep setting to never is an immense help
once it's gone off-line I can't get it to come back.
I have noticed that if it has a cached dns lookup to an ip address that that
ip address is still accessible. So if you can get OTA data live, look up google.
Switch to wifi, google is still accessible and you can do queries but you can't
click through on the links because the dns lookup fails.
I've fiddled with killing myaccount, suggested elsewhere, without success.
Unless there is some robust configuration change that pops up soon I suppose
I'll have to return it...

Did you also uninstall market updates and freeze the market updater?
It got mine working again without any problems. Sucks that this has to be done to get wifi to work properly.

I've frozen MyAccount and WiFi calling and it's working at the moment.
Truely I was a little tired and forgot about the market updates until I got
back here.
Insane that one has to do something like this for such a basic feature.
I mean who is going to use the OTA networking when wifi is available?
Let alone the cost issues. I went from 880kbps to 10100kbps going from
OTA to wifi.
This device must have rushed out the door.

Useless at any speed
So I've uninstalled the updates to and FROZEN:
My Account
Market Updater
WiFi Calling
AppPack
and the phone is still trippy. I've discovered also (via the engineering menu)
that the networking ping test fails - "network unreachable". The wifi
data looks good but it doesn't show the current gateway or dns configuration
information.
I'm at a loss for what to try next. Anyone got any suggestions?
Is there something like a netstat android app?

I am having the SAME issue as well as the OP..... =/

wifi recovery
Too soon to say that this is a consistent work-around but I'm
having some short term luck with
rebooting the phone (remove battery) in Airplane mode
enabling wifi
turning airplane mode off
Not sure if the battery pop is necessary. I suspect it's not.
I also suspect that freezing/deinstalling the various updates
is pointless.
Probably the whole work-around is to change the
Wi-Fi sleep policy to never:
settings->wireless & network settings->Wi-Fi settings->advanced
and use the airplane/wifi enable reboot sequence.
If someone has a permanent work-around based on precise setup
sequence and freezing applications I'd like to hear it - I think I've
followed the several posts on this topic and that path is unreliable but
it never hurts to be wrong.

Mine does this and I never restored any system data. I only restored apps.

Strange.
I use WiFi calling at work with no problems. It is a Netgear router. I haven't had problems at home with my Linksys router either.

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?

I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.

Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.

I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?

Fully charged. It even happens when pluged in with the charger.

My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.

Would you guys having this problem also post it here?
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.

Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.

Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again

I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.

same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone

How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.

Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

[Q] wifi issues?

sometimes it works... sometimes it doesn't... the same router on which other devices work perfectly fine... so its not a router issue...
anyone else had issues with wifi connection on the atrix... a minute ago it was showing as connected but it wasn't working so i had to turn it off on the phone and connect again
help!

Mine did this for a while it would list wifi as connected but the phone did not have a internet connection. Changing the channel on the router to 9 as well as changing the password and resetting the router fixed the problem.

Weird Probllems with With WiFi and Data
Heres whats going on... I go into the same Starbucks I frequent, the Hotspots login Fails, it state it cant determine my eligibility, call customer service.... Then I get the :No Data Connection:, and then I get the ISP Orange Triangle your password/Authorization failed, the Icons wifi, 4G and Netwoork are Blue, white white.
I switch to email, and all 3 icons are now white, I open Market, it states no connection retry.
I reboot power off/on the phone and voila, The Phone comes up, logs into Hotspots and all 3 icons are blue,
This back and forth game is repeated all the time, at Starbucks, at home, ect.
Can anyone tell me exactly whats going on and how to fix it,

@Clouded - before it took me a while before my phone auto connects but after a power outage the router shutdown and went back up again after the power outage. Guess what - Now my phone connects automatically without problem ^_^ I know my router works well but I guess a quick power cycle of router will help.

thanks folks - i'm going to try both the solutions provided. reboot wlan router & check the wifi sleep setting...
will post how it goes later...

wifi connects but doesn't work

I have a stock Skyrocket (4.0.3-IML74K.CLE5) I am using as a media player. I keep it in airplane mode all the time with the Wifi on connected to my router. Yesterday the Play store started telling me there was no connection even though I was connected to my router. I went to the web and found I could connect to pages, but constantly get security warnings. If I click continue I can go on to see the page. Netflix tells me there is a problem connecting to Netflix. Voice search works fine. Google Voice tells me there was a network error. Facebook says it can't find a secure connection. Gmail says no connection. Zedge works fine.
I have tried four different wifi Hotspots both secured and insecure. I have tried telling it to forget the connections and reconnecting. I have restarted many times, removed the battery, and tried all the frequency bands.
The wifi icon in the notification bar shows a strong connection. And the little arrows light up orange and green to show activity.
I am guessing there is something wonky going on with establishing a secure internet connection, bit I have no idea how to fix it. Any advice is appreciated.

Q&A please

Sorry about posting in the wrong spot.
I have been using it like this for three weeks. The problem started two days ago.

Update: it works again. I don't know what I did to fix it, though. I went through every setting, and did turn off screen lock and unknown sources, bit I doubt that did it.

i figured it out, i had the same problem, the date and time were askew. updated them and it worked just fine ^__^

WiFi keeps disconnecting after the nougat update.

So far I love the nougat update. The main problem I have now is the WiFi disconnects when I turn off the screen. Really annoying because I listen to music a lot at work and ever since then the music will stop randomly so the wifi will have to connect again. Rebooting does nothing and I don't want to hard reset the phone to see if it will fix it. I have already gone through 3 different note 5 because of stupid problems. it seems like a battery saving thing. the old update power saving feature used to do the same thing and wouldn't let background apps use data when the phone was off and now its doing it on all the power settings. Not sure what to do.

first off, make sure your wifi is set to stay on always during sleep (at least just to test to see if that fixes things). That said, I've experienced this too (even with that setting set to "always") and hopefully I've fixed it but need more time (and others seeing this issue) to verify the fix and actually I really don't have a fix, just a work around.
I think what's going on is that wifi is being subjected to the battery optimization/power saving stuff and is disabled or whenever when the screen goes off. I've turned off all "power saving stuff" and now wifi seems to stay on.

This seems to be a pretty broad issue with Nougat updates, on many device models. Some have suggested disabling the advanced wifi setting "smart network". I just did that and will see how it goes.

Yep same problem here and I have tired nearly everything but smash the phone so far.

I gave up trying to fix it. Nothing is working and I'm not wiping the system just for that. Mostly only happens at work on that wifi. Home doesn't really disconnect much.

I'm thinking it happens for me when the phone tries to swap between to wifi access points of the same ssid... like at hotels and work.

Might be right but I know it has something to do with it going to sleep when my screen shuts off. I have the always on turned on but it only happens when my screen is off and I turn it back on

I tried a factory reset to fix the Wi-Fi issue. It did nothing except waste my time. I've been with the Note series since the 2 and I'm done with them. I seem to also have some issue with the damn things. I've never been on IOS but I'm ready to take it for a spin.

Hello Mr Mike,
I'm to the point I can no longer stand this issue. I'm constantly getting an exclamation mark beside my wifi. The thing that boggles me the most is I don't see very many complaints when researching this issue. Am I missing something simple? I also know it's not my router. My wife has an S7 edge, my son uses my old Note 3, and my daughter has an eclipse tablet. None of those devices have this issue. I also know that nothing associated with wifi is set up to sleep. I'm at a loss!
I would hate to roll back to marshmallow but I'm seriously considering it! I'm constantly streaming music and this issue has made this a nightmare.
Any help to fix this would be greatly appreciated!!

Do you have "smart network switch ebabled"? If you have no need for your mobile data to be enabled then disable it for as long as you're going to be near the Wi-Fi network so you can still receive texts and other stuff.. Just as a sort of test to see if your mobile data is fighting with your Wi-Fi data.. Also how many devices are connected to your Wi-Fi at the time the drop usually happens? For instance if I'm using most of the Wi-Fi data, like say your speeds capped at 10MB and your wife is downloading using almost all of the speed and then other devices will not be able to use that data and your phones going to think the Wi-Fi network is being slow and rather drop it altogether.

I've tried enabling and disabling smart switch and I have the same issue. I just tried forgetting the network and setting wi-fi back up fresh (after a factory reset, logging into my Samsung account sets up my Wi-Fi from previously saved settings). So far I haven't I disconnected.
The wife and kids do use some data, but not enough to warrant the issues I've been having. Once again thanks for a quick response. I will report if resetting the connection works.

Enable developer options and under Network make sure nothing is on.. I don't know much about your type of setup but I have internet through the cable company but I use my own modem and Wi-Fi network built into it and manually control what devices can use, like what amount of speed, the IP address it can use and so on so I don't really have any issues like that.. I even have it setup so it's a white list type setup so nothing can be connected unless I personally add that devices MAC address.. Neighbors always trying to get free internet!!

Hey just found something. There's a way to check to see what's making the wifi disconnect. For me it is my gear s2. Goto wifi settings and under advanced, scroll to bottom and control history is there. I clicked on it and it said gear s plugin turned my wifi off. So I went and disabled the wifi setting on my watch and made sure to turn sync wifi profiles off also. It seemed to help at home but at work it's still happening but less often. I don't think this is the culprit for most but I have seen an improvement at least for me, it seems.

The only solution I've found is to stop buying Samsung. I went 3 months without sensors working and now my wifi is garbage. So long Samsung!

So I think I've narrowed the issue down. Yesterday I had a pool party and used a Brookstone speaker I have that plugs into the 3.5mm jack (I usually connect to several Bluetooth speakers I use). I did not have one single issue. Is it conceivable that using Bluetooth is causing my Wi-Fi issues? If so, any ideas on a fix?

It could yes since a lot of them use 2.4GHZ like Wi-Fi does but it's usually unlikely that Bluetooth would cause your Wi-Fi to get messed up because Bluetooth uses AFH which basically identifies bad channels (i.e. those that are already in use) Bluetooth technology nowadays uses what’s called spread-spectrum frequency hopping. That is, they rotate between 70 randomly chosen frequencies within their range, changing 1,600 times a second. That makes it unlikely that two devices will share the same frequency. But if you have your Wi-Fi unit in a spot where it has to pass between a bunch of walls before it gets to you that could also cause a problem since Wi-Fi signals don't like traveling through walls and other objects.

I'm pretty sure it's the new "app power monitor" battery saver that comes with Nougat. You can disable it by going to Battery> Advanced Settings> App power monitor > OFF. I recently tried it and it worked instantly and consistently.
It looked like a good idea... basically, it was an official Android version of "Greenify", only it repeatedly turns off wifi. What a joke. I turned that off, and now my wifi is stable, instead of turning off every 5 seconds.
Where do we go from here? I still want the battery savings... I guess I'll go back to Greenify and Package Disabler Pro...

I'll try that out thanks
