[Q] Ready to throw my GN against the wall. Wifi wont stay on!

Hi all, Im having a problem that is slowly driving me insane for the past 2 weeks. I surely cant be the only one. Anyway, I generally move between home and work daily, both have WIFI. When Im at home Im connected, all fine. I travel to work, WIFI isnt connected, again this is normal. I get into work and when I expect it be connected to WIFI it isnt, WIFI is off and I have to manually turn it back on to get it connected to WIFI again. Why do I have to do this? Why have all my other Android devices just worked normally and reconnect to known networks. Its soooo frustrating
Anyone have same problem or have a resolution?

What rom?What settings in phone wifi?

Both Stock rom, with and without the volume fix, and Modaco MCR4. Wifi settings are set as WIFI on even during sleep.
Is there some settings Im missing somewhere other than in Settings > Wireless & Netowrks > Wifi ??

Nope these are the settings.The strange thing for me is that your wifi turns off automatically

Try going to advanced WIFI settings and disable 'Avoid poor connections'

Yep. Try that. Only thing I can think of. My wifi was flaky with that setting on even 4 from my router. If that doesn't solve are you using any kind of task managing àpp?

I have posted this in other people's threads in regards to poor wifi reception. I recently purchased a 9250 through bell canada and have the same problem.
I have turned off the 'avoid poor connections' as well. It turns on and off on its own and can't get through a download of more then 5MB on wifi.
It will also reconnect on its own if I have left wifi turned on. I would say while WIFI is turned on I may actually be connected 30% of the time. This is 90% in 2 feet away from a router.

I'm having the same issue (wifi turning itself off) - noticed it the other day and just assume I'd caught the wi-fi button (I use extended controls). Happened again this morning and also just now as I got home.
I've not modded anything on my Nexus (4.0.1) - avoid poor connections has been disabled for a while.
I may test the theory, but betweek home and work is a wifi enabled bus journey, I never use it but it always tells me there's a wifi available. I might turn wifi notification off and see it if turns itself off before I get to work in the morning...

Left home with wifi on... Got to work and wifi was off? Wtf?
Could it be extended controls?

You are not the only one, it's happening to me in exactly the same scenario. Oddly enough it hasn't happened today.

i cant make out of your post thast the wifi on/off button turns of? or just the connection to the wifi adres?
i dont know about any sleep or auto turn of policy's as i didnt try it(i always turn off my wifi when travling)
but if its the last thing.
than the problem might not even be the GN.?
but the router it self.
even computer's and laptopt can have problems when the password is too long,or to different(hard characters like :';/.m,[email protected]#$%^&**(() ][ )
it might also be the MHZ setting,as the 20MHZ has wider range but can be disorted by machines like microwaves.
but the 40MHZ has lower range but wouldnt be disorted.
as there is also the channel option thats has been set wrong/or the pasword encryption. or any other router conflicting with the router you want to connect.
it might also be the router not liking your GN.(as my spica doesnt conect to my router at home,but all my other devices do.my router doesnt want to give a IP to my spica.)

It just happened to me again now, left the office whilst wifi was on and connected. Grabbed some lunch and returned (about 20 mins) and now my wifi button is set to off and I need to set it back to on.

Are there any policiys or settings for auto off?
you might also want to look into the power setting's,might be a power save feature.
And you are running stock? or??

Can't see any policy settings or any power save features. Running stock.

somehow I have fixed it. Problem is I don't know how.
Here is what I did in case anyone else needs help;
*From the 'My Vodafone' app, select wi-fi finder, in settings untick 'Enable BT Openzone'
*Settings, wi-fi, advanced, untick 'Network Notification', untick 'Avoid poor connections'
Not sure which of the above actually fixes it but my Wi-Fi has been on for about 1 1/2 days now.

Have you or when did you upgrade to 4.0.2? As the changelog mentions a wifi fixed. Only upgraded this morning so won't see if it has worked until I get home...

So I am still having this problem since day one. I have travelled through 3 countries and multiple cities and tried to use WIFI in at least 20+ different instances and the problem is the same.
It connects right away (really quickly actually) will stay connected for a bit then eventually loses connection.
I can't download any of the big packages for the games and so I can't play them. I won't use my data connection for anything over 100mb.
I got a message for an update yesterday. Updated the phone but I see no difference in the Android version number.
Anything happening with this?
I thought the update i was downloading was 4.0.2 but i guess it wasn't.
I am familar with updating and flashing from the galaxy s. But I want to use the phone completely stock for while.

I have just returned my nexus for a replacement. Lets see how it goes.
So far I have had the power shut off once while toggling the wifi widget (never happened on my other phone). And the wifi has disconnected twice. I have just done the update (not 4.0.2) and it seems to work a little better.

Called samsung yesterday after getting the replacement phone when it had the same issue (just as a reminder I have tried it on numerous routers/ap's) and they said they hadn't heard of the issue.
I said I was just calling to provide some feedback. They told me to return the phone yet again. I obviously believe I don't have a problem with the hardware at all. I figured if store let me return it, then why not.
Anyway onto my 3rd one today and the exact same problem.
I think that even though I am turning off "Avoid Poor Connections" it isn't actually turning that 'feature' off. Every so often and only if your watching the wifi settings it will say that it disconnected the wifi connection due to low signal.
Mind you all of this is 1' from my router while sitting at my computer. My galaxy S is sitting beside me and has maintained a wireless link to the router the entire time.

Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

Is the wi-fi sleep mode on?

Very odd. I've had no such problem at home,work or university

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

[Q] Bad WiFi software?

For a few weeks we have 2 N7100's.
With both phones there are problems with WiFi.
Sometimes it won't connect, but worse, it won't disconnect.
WiFi keeps telling that it's connected to our AP even when we're out of town.
This way we won't get on 3G.
The only solution is to throttle the WiFi.
One phone is rooted.
One phone is un-rooted.
Both had WiFi-static, but I've removed that on the un-rooted phone.
This didn't help either.
Is this something in the software?

I've never had any problems with it on my Note 2. The first week i was stock and unrooted. Then rooted with ARHD and now i'm using ParanoidAndroid, still without any issues. Can connect to any network just fine, with password and without and disconnects fine too.
Did you try and do a reflash? factory reset? reset router? Perhaps some app is messing around with it.

Must be an issue caused by the modem/router, my wifi works flawless and is super fast mate.

The problem is on different AP's (locations, brands, settings) and both Notes had this problem from the beginning.
I'm wondering if it could be caused by having multiple SSID's in the settings of which some are working with static settings.

LG Optimus G With Rogers Weird Wifi Problem

So I am having some wifi problems. Like most I have 5 or 6 wifis that I connect to on my phone. My issue is that I will need to use my data and my phone's wifi is stuck on trying to connect to a wifi network that is no longer available. I can't turn wifi off or anything. My only fix is to restart the phone. Any clues?

Yes. I believe I'm experiencing the same thing.
Here's my situation, I have the Rogers LGOG (Not rooted) and the reception @ work is extremely poor. So I turn on wifi to connect. I'm able to connect to my corporate wifi, but when I leave to go between floors and I'm out of my wifi range and return, I'm not able to connect. WI-FI is ON and it keeps searching for hotspots, but I'm not able to connect and the only way for it to work again is to reboot. Now, this does not happen consistently, but it has happened a few times to where I'm wondering is this a problem with the OS or is it the phone.
Any thoughts on this to point me to the right direction would be greatly appreciated. thank you.

Same problem with F180K, but there an OTA update arrived yesterday saying "Wifi bug fix".
Cant tell if they really fixed it, cause im waiting for my flight, so cant test it right now.

Question Wifi issues

Anyone having issues with not finding their home wifi? I'm in my house and all of a sudden the wifi will disappear and can't find it either. The only solution is to restart the phone over and over again.

Hi, yes same problem. You can fix it by going into airplane mode for 2 minutes.... but still this is a very annoying problem and the nubia support recommends to wipe the phone..... did that and same issue.... dunno what to do.
Did you find a fix in the meantime?

Hmm never had that issue with mine, did you go to the wifi settings and turn on 5g? Not sure if that is the reason it never happens to me or not. I can connect to my 5g Asus router which is on the 1st floor, and get 80 Mbps up and down on the 3rd floor. Wifi calling and text work fine to atleast with t mobile, maybe try turning that on? Hmm let's see what other settings I changed, can't think of anything else. My phone is updated to the latest update.

I also contacted nubia. I have no choice but to send the phone back which sucks because it's great for gaming.

The thing is, the wifi works as long as your at home. When you leave the range of that WIFI and come back to it, it simply wont show ANY WIFI... it seems as the WIFI- Service stopped working..... only airplane mode does work.

try and reset the network setting. I read somewhere that it's to do with the saved wifi's. I didn realized but I had 20 wifi's saved that have been transfered from my previous phone. I haven't had an issues since.
