[Q] Sudden wifi problem - Galaxy Note II Q&A, Help & Troubleshooting

Hey guys
I've had my note 2 for almost a month now and the wifi was working fine till today. It connects to my modem but doesn't open anything.
I've tried resetting my phone and modem but it didn't work. I also disabled Wifi battery saver and it didn't work either. I can't think of anything else...
Oh and other devices such as my sister's 4S/notebook connect without issues.

Nevermind,fixed it.
The problem was that my phone was connecting to a different IP(I don't know how the hell that happened).
Set my IP/PW manually in my modem and it's working fine now

[Q] WiFi and GPS stopped working

so i've been playing around with kernels the past couple weeks ive had the phone, and didn't really notice until a day or two ago that my wifi and gps never connect anymore.
When i turn wifi on, the icon comes to the notification bar but then never connects - going into wifi settings shows "obtaining ip address" but it never works.
thought it was a kernel issue so went back to the stock rooted kernel and a few others with no avail. today tried updating the modem and still nothing.
tried on home and office networks, all of which were working just fine a week or two ago, and now i cant connect to anything.
same for gps, i remember when i tried zedomax's very first kernel my gps stopped working but reverting back to stock worked fine.
ideas?

im having issues with wifi as well it turns on for about 20 seconds then turns itself off,this started happening post update,I hate this no more WIFI DIRECT!!!!!!!!!!!!!!!!!! Or even connecting to home wifi its stock-rooted,all I did was re-root after the update was sent to my phone

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.

[Q] Galaxy Note 2 WIFI connected but randomly No internet

Hi all,
I recently got WIFI connections in home and my phone wifi is acting kind of crazy.
It connects without any problems but internet doesn't work. I have to turn OFF and ON the WIFI in the phone for couple of times to make it work.
I flashed and running stock 4.3 from the sammobile after the release.
I just want to know it's is just because of 4.3 bug or my router is causing the issue. It works fine with my office WIFI network.
I can use all other phones and computers in WIFI without problems.
Any advice will be appreciated.

Weird wifi problem

Hey...I really have a strange wifi issue that I nor anyone else I have asked can figure it out. My galaxy note 2 connects to our wifi router with no issues. Works fine. BUT...occasionally it loses connection to the internet. It stays connected to the router...but not internet connection. After I turn it off on my phone and turn back on...its back on and fine.
B U T...that isn't all. WHEN it loses internet connection...it turns it off for EVERY other wireless device in the house. Laptops...cellphones, etc. Every other device will not be able to connect until I turn my wifi off on my phone and turn back on...or at least leave off. It never happens anywhere else...just at my house.
What is going on? I haven't a clue how to fix that nor what can be done...or why it is even doing this.

Have you rebooted your router?

Yes. just did again. I'm just keeping my wifi off on my phone for now. I have a tech coming out to replace the wifi router since its theirs.
I have had similar issues ever since i flashed a 4.3 rom, wifi never works properly, did the param-4.3 odin flash too.
are you stock or on a 4.3 touchwiz rom?
Ok. I have replaced the wireless router...or I should say Charter did. They replaced it with the same model though...brand new. It still has the problem. I am on 4.2 btw and rooted...but no custom rom. Any other ideas.
You running a dual band router? Try only going on 2.4ghz band.
There are also some WiFi power savings settings you can turn off that should help also.
I had that same issue when i first got my phone in Oct fresh out of the box on 4.1. I did those changes and everything has been fine since
