No longer connects to WiFi automatically

[Neoart]

I see in the first page - battery was pulled -

I'd do it again - then this time with battery out - press Home button a few times to kill any surface charge hiding.

Just did the battery pull again, this time pulled the sim.

No change. Wi-fi only connects when I force it to.

Crazy. I hope there is a fix soon.....this is driving me crazy.

Anyone know how I can revert back to 4.2.2 ? I was extremly happy with my phone then....

I've also had this same problem recently. I keep getting "authentication error" when I try to connect. When I go into WiFi settings under Password it says (password unchanged) with the parentheses. I enter the password, and I then get "scanning"..."connecting"... "authentication error." I then have to re-enter the password. Restarting the phone works sometimes. Restarting the router works sometimes. WiFi off and WiFi on works sometimes. I used to get home from work and the phone would be connected before I got it out of my pocket. Now even after it connects I get "scanning"..."connecting"... over and over. Battery use has gone up too
I read everyone's posts and just wanted to share my sad story.

Does this happen with all routers or just one?

All routers.

Well, the long-anticipated update has finally come and downloaded. However, it did not correct the wifi problem. What a bunch of morons Samsung Verizon are!

One person had to reboot the phone several times after the latest update, but he was ultimately able to solve his WiFi problem. Try that.

I did once, including a battery pull for several minutes. But I'll do it again, and again, thank you.

Yeah, sometimes you just need to show the phone that you are really serious.

Verizon replace my phone, and for the last 2 weeks its been working flawlessly.

May have to turn off "WIFI optimization" that minimize battery usage when IFI is on

Called Samsung and was told to do the following:
Go to Settings,
select More
select Application Manager
<<scroll right>> to ALL
<<scroll down>> to WIFI Direct Share
select "Clear Data"
select "Force Stop"
Remove Battery
Restart
Try
Remove Battery
Restart
Try again.

I did this two hours ago and I am still up and running. It looks like this may have fixed the problem.

I am having similar issues. Received new phone due to att telling me to do a factory reset 2 weeks ago to help with a battery issue. After the reset, the only way to connect to Wi-fi was to turn in on in safe mode, turn it off, and then turn it back on. Att decided they were going to send me a warranty repalcement because of this wi-fi issue.
My issue now is that my phone will detect and save and known wifi network, but not actually connect to it. I have both 'Auto Network Switch' and 'Auto Connect' options checked on my wifi advanced settings page. The only way to connect to wifi is to turn the device off, and turn it back on, but it even that doesn't get it connected.
Toggling the wifi tab on and off does nothing.
No issues with router/modem.
Is this also a software issue? It seems most posts prior to mine are verizon. I am on att. If it is a software issue, where do I go to update it?
