[Q] Wifi not working after i337m unlock - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi ,
I recently bought a i337m (Virgin) from Kijiji. I performed the unlock and found that the Wifi is behaving weirdly.
MY S4(i337m) is not connecting to my Office wifi. Other S4(i9500) or other phones can easily connect to it.
I can see the different connections available on the wifi page. When i try to connect from any of it, it just doesnt connect.
At home my i337m gets connected to home Wifi router. But i can only access internet when i am near to the router. If i go to different room i just see the signals but cannot access internet. While other devices can easily connect and access internet.
I am on stock 4.4.2 rom . I tried flashing with custom rom Golden Eye which didnt help either.
I even performed a flash of MK6 modem , but no success.
As i can see the connections at office and even can use wifi and internet @ home when near the router, i feel there is no hardware issue.
Please help me here as i am not finding the way ahead.

Do other devices connect with your home WiFi router? If doesn't then its likely your router is broken. If does then try resetting your router.

I have the same problem as yours. My galaxy jb 4.1.2 not work with home wifi. ..in office it works well with all wifi routers.
My laptop and other desktop connect very well with home wifi. Galaxy s3 always said connecting. .contacting. ...
I think the problem is with the security type with wifi router/modem. My home wifi set to wep security.
Try to change security type of your wifi router then tell us it works or not.
On ics it works fine but in jelly bean it never work.

wireless network problem

I have an AT&T galaxy s4 and I've been having trouble with the wireless. I can connect just fine to the netgear router at my apartment in Athens but at home I've been having trouble. At home we have AT&T uverse with an AT&T branded router. My phone will connect for a little while but eventually the small down arrow under the wireless symbol in the status bar starts blinking and the phone says it's connected but I don't have internet. Ive tried searching for a fix but it seems that the only routers people are having trouble with are dkink routers. The problem seems to trigger after I try to load a new site or refresh a page. Also, locking the phone triggers it as well. I've tried changing the security settings, forgetting the network and re-adding it, as well as turning the wireless network power saving option off but nothing works. I've rebooted the phone and the router but it still messes up. What's odd though is that my brothers galaxy s4 connects just fine (although I haven't been able to do extensive testing on his phone). Also, I was home last weekend and the weekend before and it worked just fine. I haven't rooted my phone or changed any settings that would have impacted the wifi since then. Anyone have any ideas?
I'm having very similar problems. When I connect to the wireless, the phone will work on it for about a minute and then stop getting to websites, etc. I have a Motorola SB 6121 cable modem with Vonage and a Dlink DIR-655 wireless modem. Inet provider is Comcast (only option here).
Anyone else having the same symptoms?
I've done the same troubleshooting steps: factory reset, power cycle, default settings, etc and the phone does the same thing.
EDIT: it's been working longer than usual now. I adjusted the Transmission Rate from the Wireless setup to 54 from Auto and the wireless has been stable much longer. See http://forum.xda-developers.com/showthread.php?t=2253471 for people sharing the same pain we have

[Q] i9505 5ghz WiFi Issue

At home I have a 2.4ghz and 5ghz Wifi network setup.
My S4 is always connected to the 5ghz and has never had any problems. My partners iDevices are also connected to it.
The other day when I got home I noticed that I kept getting the error 'Your internet connection is unstable' and couldn't use the 5ghz if I wasn't directly in front of the router. No settings had changed, no updates etc. It will discover and connect to the network but it won't load webpages or anything.
There is no new firmware for my router, I have tried all the different channels, and have even reset the router, and as a temporary fix I've only been using the 2.4ghz network. My iPad still works fine on the 5ghz anywhere in the house, and my partner has had no issues.
Has anyone else had this problem, or does anyone have a solution?
I'm running the stock 4.3 on the phone as I haven't even tried flashing it.

did you changed some wifi settings on your phone ??
cos if that happens you have to match the settings same both on pc{ of router } and phone
even if you are sure that you haven't changed anything just make sure and check the settings again

Wifi problems on certain networds (CM11 Android 4.4)

I got a wifi problem on my defy with CM11 Android 4.4.
At home I can connect to my routers wifi perfect.
But in school I can't connect to any network. The school has two available networks, one with a password and one without password that authorizes you through the browser.
I'm unable to connect to either of these. They have full wifi signal, but when I click connect they immediately drop to 1 "bar" and disconnect. After the disconnect I got full wifi signal again, but when I connect to drops to zero immediately.
Any idea on how to fix this? Maybe some of the network drivers having problems with networks with a lot of users?

SM-G900F wifi only connects on very strong hotspots

Hi everyone.
Since I always used CM I flashed it immediatly after I got my Galaxy S5, so I don't know if the following problem would also occur on stock firmware. I am running latest CM 13 nightly.
My phone finds all wifi networks, but when I want to connect it says: "Connecting..." (3sec), and then it just says "saved".
This happens primarily in networks with serveral hotspots (e.g. hotels). My laptop has a wifi connection good enough to stream movies, other cellphones connect, but my S5 doesn't even though it shows like 70% signal strength for the hotspot.
I tried to change wifi settings which didn't change anything and I upgraded the modem to a newer version which didn't change anything?
Does anyone have an idea? This is really unacceptable, because I am in foreign countries very often and depend on the wifi connection because I have no roaming-option.
Thank you very much!
Cheers!
Flash stock and then you'll know if it's the phone or the ROM
