Wifi unable to connect from Transformer's Sleep Mode

Guys, I have a problem with the Transformer and it's Wifi that is driving me mad!
Regardless if I have wifi running in the background or put in Plane Mode when I turn on the screen after a short interval I notice the wifi has dropped and there is no longer an internet connection.
Not only that I can not get it to start again unless I switch off the TF and reboot.
On investigation on the settings, when I click on Wireless & Networks I notice the right hand pane of Wifi & Wifi settings to be flashing as if it is trying to connect but gets locked out over and over. As such you can not access any of the wireless settings.
I would appreciate any assistance you can shed on this problem.
Many thanks in advance.

EDITED:
I believe I have now found what was causing the problem and have explained in detail in Post 10 below.
Basically I found it was after updating to v3.2.1 ~ the WiFi Settings/WiFi Disconnection Policy 'When screen is tuned off' & 'Never when plugged in' was interfering with the state of WiFi, causing it to poll and repeatedly try and switch itself back on, thus a constant flash and inability to activate WiFi..

Sorry... what does that mean?

Searched the internet, and discovered two things, I did both.
1) Removed the maps update.
2) Changed the the channel on my router to 6
Works fine now.

I'm having this same problem for the past few weeks. Whenever the WIFI goes to sleep, I cannot turn it on unless I reboot my Transformer. It's sort of annoying.

It's got to be software orientated that is interfering with the TF.
I can not think of anything other than software causing it to continually 'flash' as it tries over and over again to connect.
I need to look into date captured software updates to see if I can narrow down the culprit.
Looks like I have a long job ahead of me..... sigh!

I got the same issue, after maps update, but apparently It's got to do with use wifi for determining your location, if i switch this off , tablet connects fine after returning from sleep.

Mine has nothing to do with Maps and it's doing this continuous polling even when woken from Plane Mode and then trying to switch wifi back on.
I have a theory and am looking at it.... Will report back later.

Any news yet?

Yes, I've worked out what the problem for me was and was just coming back to report when I read your post....
Basically for me it is to do with Settings/Wireless & Networks/Wifi Settings/Wifi Disconnection Policy.
After I updated to 3.2.1 I changed the policy from 'Never (uses more battery power)' to 'When screen is tuned off'.
Thinking about it the problem has only been since I changed the policy.
So, I changed it back to 'Never' and the wifi remained on and the problem I was getting disappeared.
I then changed it back to 'When screen is tuned off' and the problem came back.
I then altered it to 'Never when plugged in' with the TF not plugged in and the problem was still there.
Plugging the TF in and the problem disappeared.
Only by changing it back to 'Never' when not plugged in does my wifi remain on ~ which if you think about it is exactly what it is meant to do.
Therefore, for me it would appear changing the policy to turn off the wifi is causing this issue of when you wake the phone up from sleep you can not reactivate the wifi and when looking at the wireless settings the whole of the right hand page of wireless settings are continuously flashing thus not allowing you to access and alter them.
At that point the only way you can reactivate wifi is by doing a power down and reboot.
So guys...... Has anyone else noticed the wifi disconnection policy effecting your wifi from sleep?

Mine stopped reconnecting again last night, the tablet would continuously reboot.
The only solution was to reboot the router.
I will try the keep on and I have turnoff wifi location.
Lets see

How did you get on with changing the wifi disconnection policy?

Changing the disconnection policy never worked, note sure if this is the best solution, as I recon it will drain the battery.

Interesting.... as it is the only way I can get a stable WiFi that will turn back on from Screen Off.
Even though it says the battery may use more power it doesn't seem all that much different if anything at all... Prior to the latest update I had the policy set to 'When screen is tuned off'.
After the update it defaulted back to 'Never (uses more battery power)' and again after changing it back to 'When screen is tuned off' this is when my problem started.
I am thinking this is something to do with my TF as no one else has reported a problem with WiFi and the 'When screen is tuned off' policy.

I just re-read my post.
It should read
Changing the disconnection policy to "never". Worked.
Note sure if this is the best solution, as I recon it will drain the battery.
Sorry.
What you describe is exactly what happened to mine.

Thanks.... This now makes a lot of sense in that it points to a possible bug with the WiFi policies.

This is driving me crazy. I have tried everythinig mentioned, but my TF still goes through the wifi connection loop. Gotta be software related...

Did you try changing the Wifi disconnection policy to 'Never (uses more battery power)'?
That sorted it out for me.
It's since Honeycomb 3.2.1 came in I now find I can not use any other disconnection policy.

This happens to me if I select anything other than "Never (uses more battery power)"
I have found though that if I uninstall the google maps update, and deselect Wifi Localization, that I can have the TF set to "Never when plugged in" or "When screen is turned off".
( see: google.com/support/forum/p/Google+Mobile/thread?tid=4778cb9a3f187b75&hl=en ) (sorry for broken link - I am new and cannot post these)
So it seems like either a problem with Google maps (that may be specific to the TF), or a problem with the TF firmware?

WiFi Won't Stay On on Lollipop

I've encountered a weird issue in every Lollipop ROM that I've tried, where when I got to sleep with WiFi on, I will wake up the next morning and the WiFi will have disconnected. It will still be on, but the network I had connected to not work unless I toggle WiFi off and then back on. It's happened on 3 different ROMs on 3 different builds. Am I doing something wrong?

Yeah, I did, thanks but it was already ticked.

You are not alone. I am having the exact same problem. The wifi doesn't disconnect, it just stops working. If i disable wifi and re-enable again it works just fine but only for half an hour ish.
Quite annoying for a whatsapp / fb messenger user .
Considering reverting back to KK backup until this is fixed :'(

[Q] Wifi issue ! (Lollipop 5.1)

Hi All,
I got the Lollipop 5.1 OTA 2 days ago and installed it - everything went smooth and the phone working fine...
But I noticed that if I reboot my router (or turn it off / on again) the Wifi don't reconnect unless I turn on the screen (the second I turn on the screen the wifi connect normally).
I didn't have this issue with Lollipop 5.0.1
P.S.
I know that this is happening because I have a led on my router telling me if any of my Wifi devices is connected or not. And to make sure I also entered the router settings to see if my phone is connected or not.
Anyone noticed that issue with the new lollipop 5.1 ?
Cheers,

I think that your problem is not switching off the router. The problem is when your phone goes to suspension (screen off) and then it drops the wifi off.
My Nexus 5 with 5.1 is doing the same

I've got some similar behaviour here, both when updated from 5.0, and with a fresh install from the factory images. When I arrive at a place with known WiFi, the phone only connects once I turned on the screen. After that, it stays connected until I move out of range and back again.

It's probably a matter of responsiveness/battery life. The more it polls for networks, the more battery it uses. It should connect, even with the screen off, within a few minutes.
That being said, I have my wifi set to always stay connected, and I've seen it not connected when I turned the screen on, then connect a couple seconds later. So, there's that. Curious how often it does that.

That's what I suspected. Sometimes, the waiting game works, but I've had my N5 lying on my desk – where it usually gets full WiFi bars – for about 40 minutes the other day, still it did not connect until I turned the screen on.
Edit: Just now, my phone disconnected from WiFi when the screen turned off, which leads me to believe that this is all caused by the WiFi sleep policy. Could it be that Google messed up something there?

My "research" has led me to believe this is the case.

Anything in terms of a workaround?
I came across those settings in the developer options (see screenshot), especially the "Always allow WiFi Roam Scans" looked promising. Been playing with them, but so far no luck.

Hi All,
exactly the same issues as yours guys are happening since I received the OTA 5.1 and installed it !
I Guess something messed up with this new update in regard of the wifi... as you mentioned.
If you come across a workaround or a confirmation from "Google" please share.
Cheers,
(With almost everyone nowadays having data ..it is difficult to notice such a behavior due to the fast wifi/data switching)

I have seen this happen as well. My battery graph will even show a missing area for WiFi indicating it turned itself on and off twice within a few hours and then stayed on after that.

Google just now released LMY47I, has anyone had a chance to see if that version fixes our problem? Once I'm off work (in about 8 hours), I'll give it a whirl and report back.

Could you please elaborate on that? I'm familiar with Tasker, but I can't think of a way of dealing with this, since I'm not sure what actually happens with the WiFi. The settings appear untouched.

I'm sorry, but my phone is now in the service center , and press that I do not remember specifically . The idea is that when you disable wifi, a time interval is forced to connect to a particular network . Look presence on the internet , here is full of instructions.

Almost all of the changes on these different builds are SIM related for specific carriers.
LMY47I was only released to LGD821 devices with SIM cards from Indian and Australian carriers

Same problem here. I am slowly losing faith in Google. Get the frickin basics going guys!!!
Back to my 5.0.1 build.

I've gone back to 5.0.1, too. Pity, except for this I was pretty happy with 5.1. Maybe 5.1.1 will actually be usable.

Do you think it can be related to Issue 163350? code.google.com/p/android/issues/detail?id=163350
I have just reported that, but I'm still trying to understand if it just happens to me or what.

I think the solution is "use vibrate mode on". Get your device to vibrate mod and test it.
I am waiting for your feedback.

I have this proble too

Are you also facing this Lillipop WiFi bug ?

After getting N5 updated to the 5.1 update whenever my phone goes into deep sleep the WIFI turns off (yes I have checked the option to keep WIFI on during sleep). But it's really frustrating as I cant get any update on my mails and on messengers. Tried 5.1.1 custom roms, they are also facing the same problems. Are you also facing this problem ?

Nope, never

I would check your router, I remember a year ago my router started kicking off people for no reason on WiFi.
Found out it wasn't the devices but the router itself so I replaced it after seeing it was faulty even after a reset and now those devices were working fine.
So check your router's firmware, try a power cycle and whatnot.

Wifi connection troubles after update to 6.0

I'm not sure if this is a Nexus 5 problem or a 6.0 Marshmallow problem but the problem occurred after the update to 6.0 on both Nexus 5s for me and my wife.
There seems to be some bug with my phone while it is asleep (screen is off but phone is on). When it is in this mode, it will not stay connected to wifi. For example, when I enter an area that has wifi, my phone will not connect. It will only connect when I wake the phone. And this isn't just a matter of the phone taking a while to connect. It NEVER connects. Before the update, my phone used to make a connection with my home router before I even walked inside. Now, I can be inside for hours and the phone never connects, until I wake it up. As soon as I wake the phone, the phone makes the connection with no problem. After a few minutes of the phone being asleep, I will wake the phone and the wifi connection will be gone. Now that it is awake again, it connects again with no problem.
I have tried forgetting the network and creating a new one, I have tried different routers, I have tried wiping the cache partition. I haven't tried a full factory reset, and I'd prefer not to, but I guess I will if I have to.
Just thought I would check here first and see if anyone had other thoughts.

Thanks for the reply. Yes, that is what I thought at first also. I meant to say in my original post that my wifi settings are set to "Always On" during sleep. I've tried toggling that between the settings but still have the trouble.

Sorry, my Nex 5 has not this issue on Android 6 build MRA58K.
Alessandro

Yup, have the same issue. When the phone goes to sleep, it seems to disconnects from the wifi and never connects after I wake the phone. When I go into the wifi settings, I see "WIFI Connection Failure". I have to reconnect manually. Like the OP, have it set to always on as well. I also know it's not a router issue because I've tried this on four different routers (two linksys, one Dlink, one TPLink) All same results.
Wonder if this is a phone issue?

Google upped this to a high priority Friday morning (Nov 6). The bad news is I think there a couple different WiFi symptoms being discussed here. Most of what is being discussed is the issue being discussed here (not reconnecting when the screen is off).
No idea when this will be fixed, so I build a Tasker profile to toggle WiFi every 15 minutes when not already connected to force a reconnect. I’ve observed it getting disconnected on its own overnight. This should avoid unnecessarily using cellular data.
I’m perpetually waiting for the next release of Android to fix annoying bugs.

Thanks for the update Gary. The comment #6 describes my situation exactly. In doing some troubleshooting of my own, I find the disconnection trouble to happen less while on a 5Ghz network vs 2.5. I still have the trouble of it not connecting initially when I come into range, but I find that it is able to hold the connection while asleep.

I am also experiencing this on my Nexus 5 and also found and starred the thread above.
I just listened to 20min of streaming with Spotify to then realize that it had gone into Doze and used the mobile data!
This is more than annoying...
Maybe by disabling Doze for some specific connectivity-related system app? Anyone tried that?

Yes, I moved virtually all of the services type of apps (the ones with the green generic Android icon) to the battery not optimized list. It didn't make any difference for me.
In some ways it seems like it might be a Doze problem, and in other ways it doesn't. Doze shouldn't be affecting anything when the phone is in my pocket and I walk in the house to my WiFi. It also shouldn't be affecting anything when the phone is being charged, which is when I see frequent WiFi disconnects.
It will be real disappointing if this isn't fixed with 6.0.1.

This is still an issue with 6.0.1. Nexus 5 (2013) 6.0.1 MMB29K updated through OTA ZIP pushed with ADB.
Things work properly for a while right after a reboot and then WiFi never connects until the screen is turned on.
Google Connectivity Services C.1.6.7 (2466695) update didn’t make a difference either.

Same problem as the thread starter. HTC A9 anroid 6.0. (newest available OS)

Same problem here with a Nexus 5 .
Please star the problem if you have it.
https://code.google.com/p/android/issues/detail?id=170078

Has anyone tested with a non-stock kernel ?
I'm asking because the problem seems +/- resolved on CM13 (non caf).
No counting CM13, do you know of a more stable rom with the problem resolved?

Does anyone here have Wemo devices? I am reading that wemos, and possibly other devices that emit their own wireless network, may cause problems. I have several of these devices around the house, and wonder if that might be contributing. However, that only would solve the dropped connection bug I have, not the failing to connect while asleep but I have.

Hi mates, my Nexus 5 (android 6.0.1,M8974A-2.0.50.2.29) gets the same troubles with wifi connection but today I tried to put some apps in non optimized list of Doze and seems workig fine.
Thats my non optimized Doze list:
-Google Play Services
-System UI
Try it and let me know if it works properly.

I had Google Play Services already set to not optimize, but hadn't tried System UI. I will try that out and see what happens.

Welp, that didn't work. Still have the error after not optimizing System UI in addition to Google Play Services.

I don't know if the issue is resolved, but at least for me, it never worked fine so many days after testing some new workaround.
So, this was what I did in my Nexus 5 (latest build, MOB30H).
Uninstall or deactivate Google Connectivity Services, reset your network settings (you will lose your Wifi networks and BT pairings), reboot.
My Nexus 5 has been connecting to the wifi networks even with the screen off for the last 6 days.

Miguun, has the error returned, or still fixed? I just got the May update, so fingers crossed that fixes it. Otherwise, I guess I'll try your fix. I don't look forward to entering the wifi network information again.

Yup, it is still working !!
