WiFi problems (4.2.1)

OK this is really pissing me off. Everyone time I go on my nexus device it doesn't automatically connect to the WiFi.. I have to either disable the WiFi and reenable it. Or just click on my network and click connect (it says its saved but doesn't automatically connect when I turn on my device), i tried everything from forgetting every saved network, restarting me device, ect, and its not my routers problem, my DNA connects automatically when I turn it on. Any of you guys had this problem? If so what did you do to fix it?

what router? My nexus 7 is fine and so is my sgs1.

No idea what router I have but that's not the problem, problem is that when I turn on my nexus and get passed the lockscreen, the WiFi would normaly automatically connect. It for some reason stopped doing that and it gets really annoying manually connecting

You could try a different channel on your router

Hi,
I share the same problem. Upon a reboot, it will work normally for a while.
Once they symptoms starts, it will refuse to connect most of the time. When it does connect, it will disconnect within a couple of minutes. WPS wont respond either. toggle wifi/airplane mode does not work either.
The only way is to reboot.
However, I did have some findings but couldnt get it fixed! Do this and test if it works for you as well:
Go to terminal (needs to be rooted device):
Simply select the "Take wifilock/B]" option and it will stay connected!
Release it and it will get disconnected and back to the same issue.
Hopefully some experts can give us some pointers?

Temporary fix
I have the same problem. This is what i did to fix it: Settings- Wifi settings- advanced- switch always on to Never, reboot in recovery, clear cache, reboot your device and go back and turn Wifi back to Always on. this is a temporary fix because if you reboot or shutdown your device, you will need to redo the steps. this is a known problem with google's 4.2 jellybean. we need an update soon!
hope it helps you.

Thanks for your help

It won't be much comfort to you, but remember that "it takes two to tango".
Yeah, there's IEEE standards for all of this stuff. Do interop problems still happen? All the frigging time, every day. Sure it is maddening.
And sometimes the problems only manifest themselves with an exact pair of firmware(s) releases between the AP and the client device. I had a WiFi router that would gladly talk to four or five unique types of devices; on the sixth - an Android phone - it would associate & authenticate successfully, but the client device would never get an IP address.
That sure sounds like a problem with the phone, doesn't it?
How did I fix the problem? I upgraded the firmware ... on the router !
Sometimes problems with intermittent connections can be rectified by fooling with things that you might think have no bearing on the problem. For instance, some routers will accept connections in A/B/G/N mode. Do you need all of those? If not, simplify your router's behaviors by disabling non-essential features, e.g. select G-only or N-only.
That's just an example - but the point is that the fewer behaviors either of the devices engage in, the lower the probability that the bug which is shared between them will get expressed.
So, you can either fool around with both devices, only one of them - changing one setting at a time to see if that alters the behavior you observe, or you can throw one device away and start all over with new combinations of devices. The router probably has more knobs which can be turned than the phone does (unless it's not your router, or you don't control it).
Good luck

This is a router issue. See my post here http://forum.xda-developers.com/showthread.php?p=41245619#post41245619 we had to replace our router (the ISP provided one) in order to connect to the wifi properly.

Hi,
it is not always a router issue!! For D-Link maybe, but not for me. My router that works fine with all my devices, only the GT-I9500 lose the connection! I also had the GT-I9505, but did not lose connection! My "old" S3, GT-I9300, doesn't lose the connection!
Samsung ...
Here, many people say them router works fine with all devices(me too), only the GT-I9500 loses the connection:
http://www.gottabemobile.com/2013/05/16/how-to-fix-samsung-galaxy-s4-wifi-problems/

After I have sent my Galaxys S4 GT-I9500 in service for the second time (when previously returned the first time from the assistance nothing had been done and continued to disconnect) they have replaced the motherboard including the wifi module that is integrated on this and now the wifi works perfectly!
I retired my S4 GT-I9500 from the service-assistance last Friday, September 6, 2013
So, I can confirm which the issue was hardware, not software!
Best Regards!

[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?
Cheers

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.

Well I got my phone swapped out (3rd one now) and I'll see how it goes.

Ni !^^ what us Your Android version ans MoDem actually? If you have that it s probable due to that i think..
Or maybe Your are a doesntt support Very well Your fréquences for match Your mobile?
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.

[Q] Data Connection to wifi

I'm using a Galaxy S4 from USC (SCH-R970).
4.3.1
Loaded PAC-MAN nightly build dated 11/16/13
All seems to work very well and I'm quite happy with the ROM. There is one glitch I'm having which I can only assume is from the ROM. Whenever I leave my wifi connection and the phone needs to switch to data, it doesn't. It takes a reboot and then all is well. This is what happens when I leave home to go to work. I don't have a wifi connection at work. Going back home doesn't cause any problems. It happily picks up the wifi again.
Other forums have had some suggestions such as toggling wifi on/off (as in airplane mode) etc., none of which seems to work for me. I need to do a reboot to get back to enabling data connection.
Has anyone else noted this? Is this a known issue? Are there any suggestions?
Thx

I have almost the same issue, for me, I randomly lose data connection, and have to reboot to fix it. I DL an app called 3g reconnect and haven't had the problem since. I don't know a real fix but hope that helps

I am in Lovely Professional University and i am facing the the same issue when connected to my hostel's wifi network . although the same kind of wifi setup is also there in the campus but there it works fine but in the hostels the phone gets restated again and again when connected to wifi .

I am also facing the same problem. In my case its only for particular settings of the wifi. On some settings the mobile is fine while in some ip address settings in college , the mobile gets restarted.

It is listing out all available wifi connections, but we have to tap on the wifi settings once we turned it "ON".

Suggest some remedy for it plzzz...!!

Fix for Wifi issue
Go to recovery mode(google it if you don't know how), Wipe cache and restart your wifi might work.

Yureka for some reason has issues with a some type of authentication protocol that these public and college Wi-Fi routers use. So this restart issues will persist irrespective of the ROM you are using.

Hi dude,
I am also facing same problem but I found a solution by installing 'WiFi fixer' app from play store then onwards its working,device is not at all restarting. But this app restarts WiFi module of your device instead of restarting entire device.

i am also facing same problem of yureka wifi not connecting in college
in home it works fine
once it gets connected but aftr that i have to restart it

I am getting disconnected after a few min,when I don't use it.After rebooting my yureka device twice,then the WiFi gets connected. Suggest me a solution please.

When I use any other rom except primary rom via multiboot patcher wifi.anf.hotspot does not work but it work good in primary rom.......why.....plzz solution
