I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?
I have noticed in the last few days that my new HTC One is not waking from sleep with WIFI functionality. When it wakes, the WIFI symbol in the notifications tray is gone. When I go to settings, And look at the WIFI option, It says that it is disconnected. When I touch to configure the WIFI settings, the settings app hangs on a black screen. I have to reboot my phone to get the WIFI back. Is anyone else having this issue?
Phone Model: HTC One
Router Model: ASUS RT-N66R / RT-N66U
Frequency: 5ghz
I am now testing in the 2.4ghz frequency and will report back my findings.
I can confirm that I don't experience this issue with 2.4ghz. No drops in 4 days. When I switched back to 5ghz on the 5th day, I got the drop and freeze within the hour.

I'm having the same issue. Can't tell what frequency band it's on when it happens though sorry.
I am having the exact same issue. It coincided with installation of an app called mute-o-matic in my case. I was wondering if the crash is related to the installation of this app. Could any one experiencing this crash comment on this?
[Update] It has happened 3 times in the last week. Wifi function just locked up, and had to restart phone to fix. Very frustrating. It's reasons like this that is driving me back to iOS. All the amount of tweaks and customization is not worth it when the phone is not reliable on basic functions. iPhones may be boring, but it at least I never once ever in years on owning them needed to restart it to fix a problem.
[Update 2] Android 4.3 update seemed to have solved the wifi crash issue. It is running much more stable after the update. Had it installed for 3 days now, and no crashes or self-rebooting so far.
Cleaning
Thread has been cleaned. Please be respectful to others and do not incite.
[Update 3]
I previously thought that JB 4.3 update has rectified the wifi crash issue for good. After over a week with 4.3, wifi crash happened today.
The wifi option page was not grey-out, but it would not connect to any network, When I toggled it from "on" to "off" state, it failed to respond. At the end, only a phone reboot could fix it.
Frustrating to say the least.
[Update 4]
I can now reproduce the wifi problem when leaving the phone running on battery overnight. During the first week after 4.3 update, I left my phone plugged-in to power most of the time, and perhaps as a result, the wifi crash did not happen.
Basically, the wifi crash I am experiencing after 4.3 update is more or less the same issue reported by others on their HTC Ones (including One, One X, One S), where the wifi failed to connect after long period of inactivity.

For now, I am going to switch "Keep Wi-Fi on during sleep" to "Always", as suggested in the 2nd link above. This should keep the wifi connection on the during sleep, and hopefully fixes the issue. I'll report back.
I have been impressed with CM11/4.4.2. Runs well for being so new and not yet having an officially 'stable' version yet.
The one issue I have had is with the WiFi restarting after sleep.
KeepWifiOnDuringSleep is set to OnlyWhenPluggedIn. Whenever the tablet is awoken the WiFi stays disabled. Manually turning it off then on again will get it to reconnect but only for a short time, maybe a minute, before it permanently disables again. Only way to fully recover is to reboot.
Note that WiFi is be reported to be 'disabled'. It does not appear to be an issue of connectivity, wireless lease, no signal...
Anybody else experiencing this?
I successfully use an app called WiFi Fixer to reconnect after sleep.

That's been an on-and-off issue for ROMS going back to CM7. The work around has been to turn off WiFi before the screen turns off. Many folks have been using AutomateIt or Tasker to handle this automatically.
For some reason my watch constantly disconnects from my phone (a One plus 2)
The Android wear app says trying to connect, but the only way is to reboot the phone. It connects again, but then will disconnect later, I'm assuming when the phone goes into deep sleep?
The android wear app has been set to "not optimised" in the phone settings.
Is there anything else to check?
I've removed Greenify and Power Nap to see if that helps, but it's the same.
Phone is running latest Marshmallow from and watch is all up to date

Are you using OxygenOS? I'm on CM13 and having same disconnects with my Oneplus2 - watch get disconnected 1-2 times per day.
Thought toggling Bluetooth Off/On resolves the issue for me, but temporary.
Is there a way to have constant connection between phone and watch?
Since changing my OS to paranoid android on my phone and removing things like, Power Nap and Amplify, I have had no more disconnect from the watch.
Not sure what services were being stopped to extend battery life

Still the same for me, I search and search, but don't find anything
Sometime a sync works for 1day, next day it's disconnected,
If I try to sync it again it takes ~1 to pair, and I dont see my apps, just default apps.
After press multiple times in WearApp to sync all apps I see it again.
Next hour or next day it's again disconnected.
I see the PlayService version on my watch is a older like my version on my phone (Note4)
Any ideas ?
I have buyed the new released Xiaomi Redmi Note 9S and i have problems with the Wifi. When you let the device to sleep for few hours wifi stops working. When turning on the phone from sleep the wifi dont work and you have to turn the wifi off and on to restore it, then i receive all the messages at once when the apps (Line, Whatsapp, etc) reconnect to inet. It seens to happen only if the device is sleep for few hours. If is only sleep for few minutes it works ok. Anyone experienced this issue, knows how to solve it?
I noticed strange wifi behaviors too
I also encounter same issue...
please advise your rom version.
my device does not get that's problem
11.0.1 global
11.0.3 india global
11.0.5 india global
I have used my RMN9S more than a week ago and I don't have any issue with WiFi. My device connect to WiFi almost 24/7 without any problem. BTW mine 11.0.3 global
Mine is 11.0.3 global. When i awaked this morning and checked the phone it was working ok. No problems at all after all night in sleep mode. I am puzzled. I hope it was a "one" time fault and it works from now on. I come again if i have news.
Just got the wifi connected without internet... Had to disable and renable
This also happens to my Redmi Note 9S.
It happens with all current ROMs. I experienced it with global, indian and eu ROMs.
Its also random, it does not happen after x hours. Sometimes its just 1 hour, others is 7 hours, others it does not happen.
What I do:
I turn off the smartphone screen to sleep, with wifi on. AC connected.
I have some apps reading internet data every 2 minutes.
When I wake up, I see the wifi icon connected. But Internet doesn't work.
When I look at the apps, I can see that they stopped accessing internet at a random time in the night.
If I turn wifi off and on, internet works again.
It doesn't happen with wifi off and mobile data connection on.
I tried changing some values in dev settings. Also in battery settings. Nothing has worked yet.
With normal day usage, it can also happens, if the screen is off a few hours.
It not a router wifi issue. My old note 3 worked fine with the same wifi. My wife's redmi note 8 pro works fine too.
It can be something related to battery saving. But so far I have been unable to fix if.
It never happens with screen on, or with screen off for a few minutes.
So I dont think its a hardware issue, I think its software-related.

Thank you DjXavy, your post is perfect to describe my issues. As anyone triying to contact Xiaomi about this problem? Are they even aware of it?
-deleted-
It could be a drivers or firmware problem. Xiaomi should be able to fix it.
What can we do:
1) If it happens to you too, please report it here and give details if you can. That way, Xiaomi can evaluate how common the problem is.
2) While it get fixed: Do someone know an app, or can build one, that check every few seconds if internet conection is working, and if it fails a few times, the app turns wifi off and on? It will require a rooted smarthphone to control wifi switch.
3) Do someone know how to send bug reports to Xiaomi? It would be good is they get a link to this thread.
I have updated to 11.0.5 now, lets see if its fixed or not. I have used the inbuilt report feature in the phone to report the issue but anything else except this post.
I have flashed xiaomi.eu 11.0.5 today. Still Wi-Fi Problems here. Hope Xiaomi get this fixed soon.
I have been contacted by Xiaomi support in the phone app. Now at least they are aware of the problem.
They called me today too. I have send them logs. At least they are working hard at this Problem. Everyone should send them logs to get this error fixed soon.
I may found the cause and workaround to prevent this bug.
Normally WiFi recognizes absence of internet connection. But in our case we're still online and I noticed some syncs still working. So DNS is coming to my mind. But I still changed my wifi to static IP using Google 8.8.8.8 DNS.
With Pie(?) Google introduced "Private DNS". I remember in MIUI 10 this feature was hidden and by default "off". On my NOTE 9S (global MI version) this setting was set to "Automatic" by default. After turning it off while dysfunctional WiFi, internet was coming back right away. After this (still) continuous connection.
The time is too short to be sure it's gone forever (*evil laugh*), but you guys could help to test.
You find the option in "Settings | Connection & sharing | Private DNS".
Good work. Continue trying things!
I switched off that same option days ago.
My 9S still have problems with wifi.
Sometimes, even switching the screen off a few minutes is enought to trigger it.
I'm still trying things, but no luck so far.
Although I've only had it for one day, I've not seen this problem yet. Wonder if it's a Wi-Fi compatibility issue or something strange?
I have noticed that I dont have problems when I am connected to a 802.11n network. The last Days I have had the Problems I Was connected to 802.11ac (2,4ghz + 5ghz). Today I was connected to an old 802.11n network and everything seems to be okay. Do you have the Problems with both Networks?

Interesting. I'm connecting to a 802.11ac wifi too.
I will switch to a 802.11n one and see what happens.
