Note II won't stay connected to wifi

**jb4kats** · 12-10-2012, 09:48 AM

I have had my Note for a few weeks now and coming from a Evolte, a great phone too, but I wanted a bigger screen and the Note definitely has that. I am here in Florida for the winter and for the first time since we have been coming here I've always used my neighbor's weak signal and wanted to have a more stable connection so I got internet service for the time while we are here.
Now I have a really strong wifi signal and have no trouble with my laptop, tablet, the EVOLTE and the wii but when I got the Note it connected just fine the first time but it drops the connection and when I try to reconnect it says "wrong password" or "authentication failed" and when this happens I have to reset my modem everytime. When I do this it connects and all is good until it drops it and if I do leave and go out and when I return I have to reset it again.
I even returned the phone and exchanged it thinking it was the phone but I don't believe that is the case. The service provider keeps saying it's the phone because once it connects to a wifi and saves it it should reconnect when ever you get in range. I don't know who to believe or what to do but I thought I might as well get a few more opinions and maybe I can find a resolution or answer to why it keeps doing this.
Anyone have any answers?

it's the phone. I have the same issue. I thought it was my internet but noticed that my laptop and ps3 would stay connected. my wife recently changed from an iphone 5 to a Note 2 so now I'm certain it's phone since both our Notes exhibit this behavior. From my understanding, it isn't an hardware issue but software. It's either something in jellybean or the Sprint Optimizer (even though I turned it off).

It's not a deal breaker because I can do so much with the phone, but it is a hassle to unplug my modem every other day.

Sorry to hear this, I haven't had any issues and I have 2 WiFi at work and 2 WiFi options at home, and no issues.

My Note II stays connected to my home wifi from the time I get home until the time I leave with no action on my part at all.

System settings, more settings, mobile networks, connections optimizer and UNCHECK THE BOX

I've been having the same issue with my GNII also. It just seems like if the Wi-Fi signal is weak it's hard for the phone to stay connected to it. I mean hopefully they will come up with a fix for it soon.

Swyped from me & my GNII

**chazglenn3** · 12-12-2012, 11:46 PM

I still have the connections optimizer checked too

Check out the settings under Settings> wifi> menu> advanced. There are some settings there that might fix your issues.

I got my note 2 a couple weeks ago. At home I have never had a problem staying connected to wifi. I started vacation today and now my wifi won'tstay connected to the wifi here. I went into settings to see if I could find the Internet optimization check box, but I don't have the option. Are there any other fixes I might try?

Do you have a Sprint GN2? If so, you shoujld have the option. When you first get to the settings level that shows an entry for "Connections optimizer," there is no check box displayed. But tap that entry, and another page opens up that does have the check box, along with a long explanation of what it does.

I don't have any WiFi problems with my Sprint GN2, and I have the box checked for Sprint Connections Optimizer.

I have a Galaxy Note as well and I dont have that option. This phone wont stay connected to wifi at home or work. So frustrated!

Has anyone had any success with this issue??? My Note 2 is about to meet it's demise! I can't take it anymore! Driving me insane. ATT has not been helpful. I have reset me router. I have disabled the wifi finders from att. I have all the same issues. It's not just my home router, it's many routers. I even called Android help. I was told it was not an issue. Strange because for me it is an issue! Please...any help....

This may sound extreme but have you tried a factory reset? It will sometimes cute glitches such as this.

**Animaljr** · 01-26-2013, 03:06 PM

Try disabling the smart wifi app in system settings. That fixed my wifi problems.

**lawmanfj** · 01-29-2013, 10:40 AM

I kust started experiemcimg this issue on Saturday. A factory reset didn't work. Took it to sprint store and had to replace the phone. They were very responsive.

For anyone with an AT&T GNII disabling the smart wifi app worked like a charm. My wifi wouldn't stay on for more than 1 minute. After I turned that app off. Im happily posting this over my wifi with no interruptions. Thanks for the post

My note 2 will not connect to the internet from multiple different wifi. I am writing this message from my laptop that is connected to my house Wifi so I know the Wifi works. The phone says its connected to the network but there is no internet connection. When I first connect to the network I have Internet for about 1 min before I lose Internet (although it still says it is connected on the phone). I dissabled the att smart wifi app and that seemed to solve the problem for about an hour but then It was back to the same old problem ( the phone says its connected to the network but there is no internet).

ps. I have also turned off all other devices that use wifi and the phone still has the problem

Please help

Have you contacted Samsung via phone and talked to their technical support?

Not sure, I rarely use Wi-Fi.

One thing you do need to do is check with Samsung, report the issue. I've heard of people here sending their phone in to Samsung for Wi-Fi and antenna issues and it comes back better than what most people have that aren't having issues.

There have been some known issues with this. The S3 was doing it a lot with ICS, but JB corrected it.

This fixed. My WIFI issue.
Thank you so much.
I have searched high and low for a solution as I have been onto Samsung twice and Factory Reset several times with no success at all.
I just tried your solution and it connected immediately. I can turn WIFI off and on now and connects instantly.
Thanks for your help.
