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.

[Q] Wifi-calling stuck 'ON' when losing wifi connection

When wifi and wifi-calling are enabled, it disconnects from the tmo network.. Great.. no problemo. I don't want it connected to the tmo network at the same time.
But.. when I lose the wifi.. i.e. service is interrupted, I leave the area, etc., then wifi-calling is stuck "ON" and I cannot return to the tmo network because the app is trying to find the wi-fi connection. This causes all voice/data to be dead.
I have tried killing the wifi-calling app via ATK, it won't shut down. I tried to FC it, no go. I tried to reboot the phone.. no go. I tried to kill it via Watchdog.. no go.
So basically, if I forget to shut off the app b4 I leave my wifi area, I'm screwed and dead in the water. Or, if the wifi connection is lost (i.e. service interruption), I'm screwed.
The only way wifi-calling will display the on/off button is when it has a wifi connection.. I know, I know.. I must force myself to remember to shut the stupid app off before leaving the local network.. but I forget at times.
I have only found 1 work around, and I'm hoping someone else can chime in on this. I'd like to see if there is an easier way around this.. It can be fixed via freezing the app. Then the tmo network kicks in. As soon as the app is unfrozen, it goes back to searching out wifi and disabling all voice/data.. until I get a wifi connection.
Thoughts?

can someone test this to see if they get the same results?

Mine switches as it should when I leave a wifi area.

Seriously? You have wifi calling and wifi enabled. You shut off wifi and it automatically switches off wifi calling?
that's messed up. If I do that, I'm w/o service. Guess I'll reinstall the app..

Thanks!!! I have discussed this on the forums a bunch of times in misc. conversations and no one has said "Hey, that's not the case for mine." I thought it was a glitch with the app.
R&R'd the app.. good to go. Thanks so much.. It's been like this since I took it out of the box.

My wifi disconnects and phone uses my data when should not

My m8 at some times usually during the night will disconnect my wifi and use my mobile data, which it should not do because in the power settings I have the sleep mode set to off and I have all power saver crap removed with viperone 1.8 I"am just on a limited data plan that I need all of my data for and wasting my mobile data sucks especially when I have wifi to use and pay for home internet that it should be using. Does anyone know why it could be doing this and a fix ? My computer never disconnects from the wifi and I use it many of the same times that the phone disconnects from my wifi, so that leads me to believe its somewhere in the phone and not my wifi. Also I have had a couple other m8's do the exact same thing. I would like to find a fix other than turning my mobile data off. And I do use a lot of data as I have a large number of email addresses added to my phone and have my k9 set to check for new emails every 10 minutes because I rely on it for personal and business use. Anyone have any idea ?

Here is my settings showing sleep mode off and power saving mode off also.

In "wifi advanced settings" do you have the "auto switch to mobile data when wifi is weak" checked off?

No its unchecked but under wifi optimization I have minimize battery usage when wifi is on ? Not sure if that could have an effect but shouldnt because mobile data would use more battery than wifi and that would have the opposite effect to turn wifi off for mobile data which would use more battery power.

I thought I remembered under venom tweaks somewhere that is has the regular PowerSave mode which has the option to disable data when the screen is off for an exteneded period of time. MAybe its turned on???? Not running the ROM right now otherwise I could look myself. Check it out:good:

I always set it up to remove the power save mode garbage in the venom aroma installer so 100% that is not the issue.

Try Wi-Fi > Advanced > Uncheck "Wi-Fi optimization"
Had the same problem and this fixed it. Haven't noticed any difference in battery life checked vs. unchecked.

Mine is still doing it, so I changed the wifi frequency band from automatic to 5 ghz and rebooted and it connected but some apps could not access data so I changed it to 2.4 ghz only and rebooted it worked ok but its doing it again this time I had to toggle airplane mode to get the wifi back on. I have to toggle airplane mode quite often actually and usually it shows change of sim detected. And some times my mobile data will disconnect and its a ***** to get working again. Maybe I will try going to a verizon corporate store and getting a new nano sim card for it. A verizon dealer could not get a new nano sim to activate before and they ended up getting my old nano sim reactivated which I thought once a sim has been deactivated that they cant reactivate it but apparently they can. I really dont know what else to try other than a new sim card. Anyone ?

Any chance you could temporarily try a different wireless router? Some of these new phones are finicky with some wireless routers... Could be a miscommunication between the phone and router somehow.
Don't really have an explanation, one of my old HTC devices had issues connecting to a specific wireless router, where apple products did not have the problem, and vice versa with a different router.

Having been the case with at least 3 m8's I honestly do not think its the router because It happened with my old moden and router and also with my motorola surfboard SBG6580 modem / wireless router combination that I switched to a couple months ago. And it will also do the same on my girlfriends modem and wireless router. I think there is something in the m8 that is the problem and one other of the m8's was an at&t version. I"am not 100% sure but it may have all been while using viperone, as there really is not much choices for daily driver custom roms especially since elegancia closed its doors. Dont get me wrong tranquil one m8 is not bad and cleanrom is ok but they are no way as easy to customize as viperone is. Years ago I use to like cleanrom for its DE which was barebones the way I like it, good clean and fast. I just dont trust any of the other roms to be bug free enough to be a daily driver. I have just had too many issues in the past with cm dont get me started on them lol, omg was nothing but fix after fix that you had to do nothing like being a Guinea pig lol.

Wi-Fi not connect after phone is woken from sleep mode
Both my wife and I was having the issue with Wi-Fi. I tried everything ,turning off optimization, setting for 2.4ghz,and every other thing listed. Nothing helped until I flashed the firmware from the digitalhigh thread, took 30 sec and fixed Wi-Fi for good on my wife's m8 and mine. I lost nothing in the process except that very annoying Wi-Fi issue. I was then able to set any options like, Wi-Fi optimization and Auto band detect, everything working great!
Here is link to that firmware...

Just downloaded and save to SD card root and rename to "0P6BIMG.zip" and boot to hoot to install.

Galaxy S7 disconnecting from wifi while in standby

I have a stock galaxy s7, no root, no custom rom. When I wake up the phone from sleep, I often find that it lost wifi connection and I have to reconnect it manually.
I have tested 3 wifi networks and this happens only with 2 of them, so this make me think that it's a modem issue. BUT my previous phones (lg g3s, samsung galaxy s4 mini, meizu mx5) worked fine with the same connections, so this make me think that it's a phone's issue.
I have ''smart network switch'' disabled and also ''bluetooth scanning'' disabled (I read on AndroidCentral that bluetooth scanning could cause the problem, but it's not my case). The problem persists even with the latest firmware update.
Any suggestion? What can I do?
All the wifi networks I tested are 2.4 Ghz, the signal is strong and the wifi channel is relatively free.

I've experienced the oppsite problem.
My Wi-Fi is always on. Either I choose the "While charging" or "Never" option in "Keep Wi-Fi on during sleep" setting in Wi-Fi More menu.
Here I find an article about How to disable background Wi-Fi and Bluetooth scanning in Marshmallow.
But in S7's firmware there isn't Scanning option in overflow menu in Location setting like it showed by pictures.
I'm very confused.

The options that you are looking for are in a subsection inside the location settings. I don't know how the subsection is called in English because I'm italian and I use italian language, but it think it's ''location improvement', or something like that. Also, I have the exynos version of the S7, if you have the snapdragon one maybe this subsection could be absent or in another position.
But to be honest I don't think that you can solve your problem this way... Have you tried to reset to factory settings? Or have you checked if there is an app that forces the wifi to stay awake?
Btw, I did not solved my problem yet. I contacted Samsung assistance yesterday, and they told me that I have to send them the phone for reparation, but I'm sure that it could be solved modifying some parameters on my router... I don't want to leave them my phone for 2-4 weeks, beacuse I'm sure that they would send me it back with the same problem. If I find out a solution I will post it.

Yes, both works fine. I have the Exynos SM-G930F

I solved the problem. I disabled the WOW FI service on my router and the phone never disconnected again. WOW FI is a new service of my internet provider that allows to share your wifi connection between all the customers of the provider, splitting the wifi connection in 2 separate connections, one private and one public. For some reason the S7 didn't like the second connection.

Samsung S7 WiFi forced to sleep
Hi
I've been having this extremely annoying condition too, since the last software update.
I came to the conclusion that it was some kind of aggressive power management setting that was putting all kinds of apps to sleep.
Today.... I think I might have found a solution... I say might, as it's only been a few hours..
So I've done is this..
Go to settings.
Search for "Battery"
Click on the three menu dots in the top right hand corner.
Click on "Advanced Settings"
Turn off "App Power Monitor"
So far, so good.
My WiFi stays connected and the 2 VoIP apps and Text-to-voice app are alive and well.
Curiously, my battery drain doesn't seem affected.
I'd be interested to know if this solution works for other people.
Good luck.

Wifi keeps disconnecting?

Hey, guys I just got my Pixel 2.
I connected it wifi but it keeps losing it. Only if I reset my router it will keep the connection for a while, but somehow when
I get to work or in the morning the same issue appears again. It connects but when I go to an app which requires wifi it drops.
I tried to change the channel but didn't work as well.
Restarting the phone won't help either. I also don't want to factory reset it since I want to keep all my data etc. I don't want to go all that bs.
Maybe I should have stuck with a new iPhone after all. Sorry for that comment, but I'm really frustrated
I don't want to give it back or some ****, I just want to fix it easily so I can move on. I hope I get some advice here.

this can help:
phone ::: Go to setting > wifi > advance > If there is Freq option then change it to 2.4Ghz
router (in case no option on phone) ::: go to Wifi setting of your router and disable 5Ghz. I can help more If I know model of your wifi router
:good:

I'm having the same exact problem as OP. I thought for a second I wrote the post. Would love to see if there's a solution. I don't see the option to change frequency in wifi settings. And this issue for me occurs on different WiFi networks.. so it's not just one router. Ugh!

Exactly the same issue here, which is what has lead me to this thread. It often happens that my phone switches to mobile data suddenly while working absolutely fine on Wi-Fi. I have tried almost every basic solution but condition remains the same. Also during that time it stop showing me my (saved) Wi-Fi in the Wi-Fi network available, while at the same time my same Wi-Fi is connected to all the other devices in my house. This needs a fix.

still no fix
