Wifi turning off itself?!

Hey guys,
need some help with my htc desire. Just bhought it couple of days back. Everything worked good, until today, as wifi turned itself off after 10-15 min on standby and automatically connects to 3G instead. Even if i turn on the wifi, it will say that the wifi is on, but its not actually connected I have to restart the phone for it to connect with wifi again. And the same thing goes over and over again. Has this happened to anyone?
Please help! :S
I have the orignal firmware, not rooted.

Sort of happening to me too, but after the phone is asleep for long periods, like overnight.
For the past few days, I leave it with WiFi on when I go to sleep, I wake up and WiFi was off. I switch it back on and the phone doesn't seem to use wifi, or it does but just hangs.
Only started happening after the last hard reset, was working fine before that.
I do have the sleep after 15mins setting on, but obviously that shouldnt switch off the wifi, just let it sleeps and should reconnect after waking up.
Waiting for a exchange for another phone due to another issue, but will keep an eye on this, might be the Setting Profile app I've installed that's causing the issue.

My wifi switched off by itself after going standby for sometime.
After I wake up the phone, it will reconnect to the wifi. Not sure if there's app to prevent the wifi from going into standby though.

I have been using the phone for 6 days now, before this my phone could be on wifi all night, and when turned on in the morning the wifi will still be connected. Its strange this should happen now. I installed juicedefender yesterday and than uninstalled it again after trying it..might this has affected my wifi settings.

That's weird. I did installed Juice Defender and uninstalled it as well. Not sure if that's the cause. will do some search and see what I can find out.

FOUND!
We can actually control the Wifi Sleep policy by going to Settings> Wireless & Networks> Wifi Settings> Menu >Advanced> Wifi sleep policy!
Change it to never and it should work as before.

Yes, I know about that setting, but once you wake up the phone, it should wake the wifi and it should reconnect. This is not happening, and in some cases it does switch back on and connects, but doesn't get onto the internet. Seems the phone is still trying to use the cellular network.
Leave it on all the time eats up battery, so rather have it on sleep after 15mins

[Q] Airplane mode with Wifi on

I spend most of my work day with no signal, so my battery dies quick constantly searching. I've now got google voice setup, so I can do everything i need over wifi, but can't enable airplane mode without it preventing wifi from working as well. I'm running SFR 1.2. Anybody have the same issue and or know a way around it?

Turn Airplane Mode on and then turn Wifi on. Wifi will go on while Airplane Mode is active. If you have Wifi on and then turn Airplane Mode on, it will turn Wifi off... just re-enable Wifi.

That's the exact same issue i'm having. I can attempt to turn wifi on, but it seems to just grey out the options with airplane mode on. From either the quick launch bar, or directly in settings i get the same issue.

Just tested this to see...
Works fine stock ec05. Must be something isolated to SRF

that's funny because I was just looking for an application that does this too. SRF 1.2 won't let you enable wifi with airplane mode on. I don't know if this is an SRF issue or if it's like that for all ROMs. anyway, I found this app [(download here)] and it works perfectly. very simple to use

It works on stock and I have also used this method with various midnight ROM's

Stock Froyo has always had this ability by default. Must be an isolated custom ROM thing.

here try this also. Turn on your wifi first, then turn airplane mode on & see if the wifi stays connected. this method works for me on SRF 1.2

I just installed "Airplane Mode Wi-Fi Tool" from the market and so far it's working great for this. There is an option you can enable to always leave Wi-Fi on when entering arplane mode.

I'm running syndicate frozen 1.2, and I have not been able to turn WiFi on while in airplane mode when I was able to do so with stock ROM.
I don't see an app called "Airplane Mode Wi-Fi Tool". Anyone with a direct link or alternative?

I used Airplane Mode Wifi from the market, and it worked fine. what's funny, is ever since installing the app and setting it to "always allow wifi during airplane mode" i haven't had a problem with it anymore on any rom or any kernel.

Hold power button for a few seconds. Select "Data network mode" to turn off mobile data. Press back button. (Soft key or hardware, doesn't matter) Turn on wifi.
What be the problem gents?
Sent from my SPH-D700 using XDA App

The fact that it doesn't turn the main phone radio off, and would still leave me with a dead phone by the end of my work day. That's my whole reason. I have no signal all day at work, but plenty of wifi (hooray google voice.)

I keep a charger at work, because I get zero bars at my desk but sometimes it will send/receive texts. No wifi available for me.
Maybe you could...plug it in at work?

I plug it in when I can, but I'm the only IT guy for 300 people.. don't get to spend much time at my desk.

Wi-Fi turns off when phone in deep sleep

Hi, I saw many posts related to this topic Wi-Fi turns off when phone in deep sleep but not able to find a single working solution.
My phone runs on 4.2.1 with wi-fi sleep policy set to NEVER ( that means always on ideally ) , and tried turning on / off wifi optimization, avoid poor connections is not ticked.
Even after doing everything the wifi is turned off after sometime and when i turn on Screen it turns it back! How to do I solve this?? I am using STOCK rom, with just root.. No other battery saver etc. app installed.

well i have this problem too on every jelly bean rom. the only rom without this problem in cm10 stable. now i'm with cm10.1 hoping they'll fix it like in cm10.
when that problem comes out just toggle on and off airplane mode and it should disappear until next wifi toggle off and on.
I hope google will solve it in key lime pie

CM 10.1 has only just started doing this in the last week or so, it was fine before. Was wondering if it was just me with this issue or not...

Am i correct in understanding that you don't want it to disconnect? The option in the settings is "Keep wifi on during sleep". If you have it at Never, then it will disconnect when the phone goes into sleep. It should be placed on Always because you want it to be on even during sleep
Flowed and Tapped from my Nexus

fixed the wifi problem
Heya! My first post!!!
So, i had the same problem on my Allview P5 Quad.
The guys from Allview released an update for my phone based on 4.2.1 and i thought the problem was from them. I had WiFi turned on and after a few minutes from entering sleep mode, the WiFi got disconnected, both WiFi and data. I have installed the last update again and again, rooted, unrooted, tried every option from WiFi and i still had the same problem.
So i timed the time when the WiFi disconnects and it was exactly 6 minutes. So i thought that it must be an option that does this. So i unchecked the Quick Power Saving icon from Switches and ... SURPRISE! My WiFi stays on continuously. So, the problem is from the system power saving settings. I hope this helps all of you.
P.S. Love this forum! Thanks for all your help!

I believe I found the problem, some how it is not the phone but my wifi router (and all routers) is the problem. Go into your router settings and look for the "Beacon Interval" and set that number to 50. I'm not going to explain what the beacon interval is, go google it and you will see. I switched mine and now the wifi on my phone does not switch off when in deep sleep.

Battery drain on standby

Guys the battery on my s6 edge has been draining just by sitting here. Anyone else having this issue?
Sent from my SM-G925T using XDA Free mobile app

Yeah I've been seeing some serious battery drain. Way more than I'd expect with the battery size. Not sure what's going on.

Turning on your Wifi will kill your battery. I've had to restart my phone to make it stop sometimes. Makes me wonder if this is why the nexus skipped 5.0.2.

That may very well be the reason why nexus skipped it. Juding by the previous samsung record, it will be a while till we get 5.1

Did you have Wifi on at any point since your last restart? I've had to reboot the device to fix it.

Try turning off volte. That seems to help.

This is what i hate so much... you pay ridiculous amount of money to buy a "Smartphone" but then you have to turn all these features of to make it work efficiently.

I'm sure it's just a software bug on T-Mobile, but I was able to fix my issue by turning off WiFi, completely charging the phone, and restarting. WiFi is what causes it, not sure why though.

Go to settings and search for "Phone" from there you can get into call settings.

google services for me is using the most battery, which doesn't make sense.

Did you also disable the "wifi during sleep" that is used even if wifi is off? Can't remember where it is. Maybe advanced Wifi or in Location settings. Just curious. Thanks!

Gotcha. I was curious but also sort of pointing out that even with Wifi turned off, the phone will still use Wifi for location unless you specifically disable that option. It may or may not make any difference at all, but since there's a bug then it's possible that ANY use of wifi is draining more than it should (even if it's just intermittently every few minutes for location checking).

If the WiFi being used during sleep is causing any issues, the issue is small enough that it is not showing up on my battery usage page.

Well for example. I have had Wifi turned off since before unplugging my phone this morning (8 hours ago). Despite that, it has been used for 29 minutes because I didn't have that option (use wifi for location even when it's off) disabled.
Because of this, I'm disabling that location feature as well for now. I bet that's about 30 minutes my phone has been held "awake" due to this stupid bug!

If it's causing issues for you then turn it off. For me it wasn't enough of an issue to disable WiFi during sleep.

Assuming you are on 5.0.1 Lollipop, did you factory reset after the update? Many people have experienced problems after the update but have seen factory resets correct problems.
While on the wifi settings page (the screen where you find the list of wifi networks available), touch the three dots in the upper right corner and select Advanced.
Uncheck (turn off) the option to "Always allow scanning"
You can also turn off the first option of Network notification to stop it from trying to find open networks in range.
hope this helps.

I am on 5.0.1, I did factory reset twice, Cleaned cache multiple times

Weird... mine does.
Are you running any special apps (like battery savers)? What Wifi settings are you using? Is Power Saving Mode on or off?
I'm curious now. But yeah, several Note 4 users on the non-ATT Note 4 thread are reporting this issue as well and so were many Nexus users.

No battery savers or apps designed to conserve battery; power saving modes off. All I did to wifi settings was turn off scanning and notification. I have a long list of apps that I disabled since I knew for sure I wasn't going to use them. I screenshot them below if you're interested.

Ok I was wrong. My phone doesn't show wifi always on. I kept wifi off all day and it showed correctly. BUT I think it did show as always awake on the previous Lollipop update. (I'm on COC4 now).
And btw, I have all the same apps turned off as you except Samsung Push Service because it seems to not sync S Note with my Samsung account (I have a Note tablet too) and Amazon because I use it.

Update
I did some further digging , based on the amount of battery used.
1. Cerberus App was using a lot of battery, so uninstalled and re-installed it... the Constant AWAKE problem is gone
waiting a few days to make sure that problem was really gone
2. Uninstalled "LLAMA" app and now WiFi does NOT show as always on

Having the exact same issue on my galaxy s6. Just turned on clash after picking up the phone and the resolution looks like as compared to my joke Moto X (2013). It's worst when zoomed way out and fine when zoomed way in. Maggie everywhere. What the **** supercell.
