WiFi doesn't connect automatically with screen off - Galaxy S 4 Q&A, Help & Troubleshooting

Hi there. It connects fine as soon as I turn the screen on. Not sure what the problem is. I believe it's a 5.1.1 issue.
http://forum.xda-developers.com/google-nexus-5/help/wifi-issue-t3059452
That link has the same issue and they couldn't figure it out either.

In wifi advanced settings check the wifi sleep policy..
Happened with me before and i found that it was set to sleep while screen is off

I've tried everything. It's not that the wifi turns off when screen is off. It's that it stops scanning to connect to a new network automatically. It'll stay connected to whatever wifi I'm on as long as I'm in range but as soon as I'm out of range, it won't reconnect.

I had the same issue with some non Touchwiz roms like CM and GPE. I believe this is caused by the router. While I am at work it keeps disconnecting, while at home there is no problem at all. So I believe router is the cause of the problem. If you have access to the router, I would try setting to different channels and try.

Thanks for the advice. I had thought that too but I've tested other routers as well. It's a software issue as it works fine on Touchwiz. It's not that it disconnects, it just doesn't switch to any other saved network when the screen is off. As soon as I turn on the screen, it connects right away. All routers and SSIDs.

[Q] serious wifi issue!!!

After spending time searching the net for a solution i couldnt find anything as it seems my problem is unique. The issue is when i connect to my router through wifi every thing goes fine however when i go out of range or disconnect for a while and try to reconnect i get a message "Connecting..." then "Disconnected" and it never connects until I restart the router. The issue was worse where it connects for 1 time but the next time it does not detect the router, this was resolved by setting the wifi channel from auto to channel 6. But now i am stuck with this issue that has no solution. I have tried everything from static IPs to mac filtering, i also wanted to update the router (gigaset 504 agu) firmware but could find it. I am currently using x10 with firmware 026 -global. If anyone has a solution plz share it as this problem is really annoying

I have the same problem with my netgear router, it is very annoying...I think this a known issue with some android phones and certain routers.
Its seems no one has a solution, I guess we need to wait for 2.1 and see if the update resolves this issue

Well you could provide internet connection to your phone via your computer. What OS do you have and what kind of internet connection (wired/wireless) does your computer use?
Not that I've ever tried or used it seen as I don't have issues but perhaps this might miracally work..

I believe its worth a shot
P.s - Im pretty sure I've read up on a similar thread to this before..?

It's an android problem. I have this with my x10 and froyo nexus one. The only solution is to quick toggle wifi on/off in the power management widget. I've seen this happen on a Linksys wrt54g and wrt120n. Same with a D-Link dir655m and dgl-4300. If you are really unlucky like me. Having wifi and bluetooth on at the same time with this problem will cause your phone to either freeze or reboot on its own.
I get this with some routers, what works for me is. Data /3G, wifi off, 3g on, wifi on. I use switch pro to quickly configure the toggles.

just to be clear...do you mean you switch off data/mms then wifi off...then switch on data/mms and wifi.
thanx guys for the reply, but none of the mentioned solutions worked
I am seriously thinking of moving out of android because of this issue, its as if the phone doesn't have wifi?!?!

[Q] Wifi stops working

Anyone else experiencing this? I go between wifi for work and home, and wifi stops working when I do. When I go to the wifi settings, it shows Wifi as "scanning" and shows remember wifi networks, but no actual live networks. It pretty much happens every time I go between work and home and a soft reset or manually cycling wifi off and then on fixes it.
I get the same issue when connecting to 5G N network... it tries to connect the disconnects... I usually restart and it works fine...

This sometimes happens on my mt3g. Maybe a froyo issue and not a phone issue.

Wow, I think you may have hit the nail on the head. At home, I am 5ghz N only, and at work, I connect to 5ghz N half the time, and 2.4ghz N the other half.
Where would I submit the bug for this? HTC? I can gather up enough technical data for a good ticket.

Sudden screen on

Anyone experience that when charging,
the screen suddenly turns on?
I see it happens a few times during charging. Any solutions? Thanks.
Yeah, been happening to me too.
I noticed if u power off then start up again then put it to sleep, it does not wake up.
I think it might be something to do with market for some reason.

the América happening here. It's happening also when it's not charging. I don't know any solution anyway.
I have the same problem on the first day using but it went away by itself.
mine has been doing that too. at random times, the screen wakes up. perhaps the proximity sensor is too sensitive? i *think* that it only happens when i'm just a few feet away from it.
Mine has been doing it as well. I ended up doing a factory reset. So far it has not done it again. Mine was happening while not charging. Not sure if it was while charging.

Adressing the problem
ADRESSING THE PROBLEM:
I have this 'bug' so now and then...... and I have found the 'problem' : it's the wifi connection between the accesspoint and the tab! I can replicate the 'problem'.
1) on my work no problem. Iconia stays asleep. Router/accesspoint : Thomson
2) at home, downstairs..... problems. Randomly it wakes up. Router/accesspoint : D-Link
3) at home, 2nd floor no problem. Device stays asleep. Accesspoint : Sitecom
So I have adressed the problem to the D-link router. Then I tried different wireless settings in the wifi setup (b/g/n connections, wpa/wpa2/no sec) no luck. The search continues.
It's a first direction. Don't search in apps or something else because I can adress the problem to the router (type).
=> please confirm

I am going to check this theory out. My main access point is a dlink. My alternative point is my older linksys. I'll post a confirmation shortly.

Unfortunately I don't think this is the issue as I have a linksys router.
I believe the issue has something to do with syncing/wifi activity as it does not happen when wifi is off.
OK after testing the two different routers I have had no issues on my linksys. The dlink was causing issues. However I am not sure it is necessarily the router as much as it may be the type of security. My linksys is set for WEP while my dlink is setup for WPA & WPA2. This could be a cause. My tab is working normal now on the WEP secured linksys. I am too lazy to change my router's security settings to verify further since it now works.

I also have a Dlink DIR 655 router and was having the same issue when my acer was connected through N mode. Switching it to use B/G fixed the screen from randomly turning on and off. Hopefully someone has a fix for this.

I will write a little app that will close down wifi when the screen is turned off and will activate it again when the screen is turned on. Maybe this will work as a temporary work around till Acer fixed the problem.

There's a setting under Wifi that allows you to have wifi turn off when the screen turns off, never when charging or never at all. When your screen comes on, so will wifi. The disadvantage of course is that you lose all notification abilities of the tablet when the screen is off as it won't get emails/ims/etc.

Ahh, ok. Sorry I haven't read where anyone has tried that.
GL then.
I too am having the same issue. I use a cisco valet router and notice yesterday that while my tab was sitting on my table the screen would radomly come on. Not exactly sure if it's an issue related to a router, and I am using just wirelss N. I wonder if there is a way to get some sort of dmesg or log or what ever the hell its called to see what the system is detecting at the time the issue arises. If there is a dev to point us in the right direction I would gladly post a log of some sort if I new how to pull it in the first place.
I think this is caused by various programs wanting to synchronize data / mail at different times while it is sleeping. My tab does this when the screen is off; if I quickly push the sleep button when it first comes up it seems to stop it for quite a while. If I have wifi off, it does not do it at all.

Question about Wi-Fi

Hey does anyone else have problems with the Wi-Fi? It seems that when I turn the Wi-Fi off and want to turn it back on it takes significantly longer to turn on than with my previous android
And I've also noticed that sometimes when I walk out of the range of any router it kind of gets stuck and I'm forced to turn the Wi-Fi off and back on
If anyone reading this post can just add a quick reply saying whether they have this same problem or not that'd be nice
Thanks

Yeah, I'm having the same issue when I get out of range of my campus' WiFi range. It seems to get stuck on that network and never disconnects and I have to turn off Wifi and turn it back on.

I was planning on trying my campus' guests network tomorrow and see how that works out. It my have to do with the verification that my university uses. I would suggest trying the same, if you have a guest network that is.

Same problem here on campus.
Tried using "Best Wifi" and "Wifi Strongest Signal" but I don't think they've been helping.
More of a problem for me since I'm only using this as a Wifi device. (Not activated)
Do iDevices suffer from this issue?
Yeah, I have been having problems with wifi itself. For me, after I turn it off while connected to my home wifi network, I will not be able to connect back into the network until I restart the network. Anyone else having the same issue as this?

[Q] Wifi won't stay connected.

Is anyone else having issues with Wifi not staying connected? For example, it'll keep dropping out from my router every 3 minutes or so. When it drops out, the 3G will enable for a few seconds but then it will connect back to the router.
Is anyone else having this issue? What did you do to fix it?

Are you rooted? Have you done any mods? Perhaps you should check the advanced settings in the WiFi option
Sent from my GT-I9505 using xda premium
Hi,
No I'm not rooted. No mods at all. 100% stock firmware. I have checked the Advanced Wifi options but can't see anything wrong.
Just to mention, I did at first think it might have been a fault with the phone so I got the phone swapped out with another brand new device however the problem still persists.
I have a similar problem on a i9505 running the latest CM 10.2 nightly.
Some 2.4GHz networks are fine, others behave as you describe.
The one 5GHz network to which I have access has recently started to misbehave; the phone connects properly and works for about 2 minutes, after which I lose all connectivity (I can't even ping the router) yet the wifi indicator remains blue. Turning wifi off and on again gives me another 2 minutes. This goes on until I give up and switch to 2.4GHz.
Of course, I have no idea what is causing this. I've tried various channels on the router, as well as rebooting it.
Does this happen to all routers (I assume you use other routers somewhere else), or it just happen to this router only? Is this case, you may want to check the router itself.
Sent from my GT-I9500 using xda app-developers app
Frequent disconnections occur on all 2.4GHz networks. As for the 5GHz, I've only got access to one router on which to test it.

I've only tested it on my router.
As I say, I thought the phone was faulty so I swapped it out but the one I swapped it out with had the exact same issue.

A couple of things concern me about this method though. Do we know what setting that mode to OFF actually does? I've heard reports that the phone gets quite hot and battery drains.

Have you try to make a Fullwipe? For put tint everything restant as when you have buy it?
You will be on a custom rom with ni mldem update i dont say but chère..
WiFi still disconnecting even on 3rd device...
Wiping /system and flashing a newer nightly fixed the 2.4 GHz problem, but 5GHz is still dodgy. It's not the (Netgear) router as I have a couple of other Cyanogenmod devices which operate without any problem.
Perhaps I should start another thread as this may well be something different from what is affecting the op's device.
