my wifi at work is bad after I took the mja update. another guy at work is having the same problem after the update. it connects fine but it disconnects... non working wifi with one bar... and keeps switching from 3g to wifi every few seconds....or it would work for an hour then bad again. My home network is stable and doesnt do this... other people at work with different phones has stable wifi.

yes continously is the perfect word.

Might be a issue switching routers that use the same name

I odined the mja modem on aosp, and running very well. So it must be a problem with mja kernel.

Same here so I back on 4.2..... mja modem is ok. So it might be a kernel or the Rom it self

Wifi issues

Just got my s4 and I am having a issues with my wifi. When I connect I can use it for about 5 min then it stops downloading. The icon on my phone shows that it is uploading but I don't think it is. Anyone else having wifi issues? I know it's not my wife because my ipad and all my other wifi devices work just fine. I have dlink dir 655 wireless N router and I am not rooted.

Hah, "Wife issues."
But so far, I haven't had any WiFi issues. Mine has stayed connected consistently.
Yea sorry bout that didn't notice that my phone doesn't know what wifi is haha. I don't know what's going on with my phone. It just stops downloading then like 5 min later it starts then stops again.

does it keep disconnecting & reconnecting?
Yes, it locks up showing that it is stuck uploading then I have to wait a minute or 2 for it to disconnect then reconnect.

I also have the dir 655 router and have the same issues connecting. After searching this issue, it appears that this router has compatibility problems with Samsung phones. I have connected with no problems to AT&T's hotspot, my wifi at work, the wifi at my car dealer when getting service. I only have problems when I'm at home with the Dlink. I've tried WPA with TKIP, WEP, and no encryption at all and it will constantly lose connection no matter what I do.
My work uses an ASUS router with WPA2 and AES and I am connected all day so I went out and ordered one. Hoping that when it arrives on Tuesday that I will have no more problems connecting.

Sorry about the wrong thread it was late last night and wasn't paying attention, also why the title of the post was wife issues haha. Good to know it is not my phone that isn't working . I have another wireless router I am going to try out here in a bit and see if my dir655 was the culprit. Thanks for the heads up!

Just set up a netgear router I had as a spare and no problems now! Hopefully someone can find a fix for the dir 655, such a good wireless AP! Thanks again Will822!

THere are a few reports of incompatible routers
I'd suggest to try a different router to see if the WIFI works

Ye try a new router or check for a Firmware update for your router, all the issues I am seeing with WIFI are incompatibility between the S4 wifi chip remember it now has AC standard included as well as N. In most cases a router that is less than a year old should have a firmware update older than that your mileage will vary.
Well it connects to the router and usually works to load a web page or fb once n then stops working but today its been working ok apart from once or twice so I doubt its the router if today its been working ok today mostly but I could be wrong

Wifi issues with 4.3

After upgrading to 4.3, I have lost my Wifi performance to my normal router. Now, while still able to scan available routers, I'm no longer able to connect.
Anyone know of a solution, short of an RMA?
Sent from my Nexus 4 using Tapatalk
Wat kind of router are you using and what frequency? 5Ghz or 2.4?
Sent from my Nexus 4 using xda app-developers app
One is a linksys, the other is unknown as it's at the doctors office. As for frequency, one of each.
Sent from my Nexus 4 using Tapatalk
Change wifi channel at router and try again.
With other wifi networks works fine?
Sent from my NookColor using Tapatalk 4
No. I have no connectivity. Wi-Fi performance has slowly diminished since I did the upgrade.

Setting a static IP has fixed it for me. Setting it on the phone that is. Happens far less now than when i didn't have a static IP.
How did you upgrade at 4.3?
Through official OTA?
if you could check it, reflash only radio.Img from factory Rom.
Sent from my NookColor using Tapatalk 4
My issue is not that bad.. the only issue i have since the update is the wifi signal drops completely, and the router next to me on my desk. The signal comes and goes for a couple of minutes then goes back to normal

The upgrade was done via a full wipe (was rooted at the time) and flashed the image from Google. Phone has been stock since. After the upgrade, I noticed the Wi-Fi signal went from four bars in the living room to three. Before losing connectivity completely, then two. One to none happened pretty quick.

WIFI slowdown bug still on 4.3...

I just upgraded my n7100 to 4.3 and the wifi bug (slows down after a while in standby) is STILL present! Is there a reason why this is never fixed?
I have tried with CM10.2 and that bug is not there.
I have same issue on 4.4.2 omnirom. So annoying.
Sent from my GT-N7100 using Tapatalk
I think that, this affects only specific models. I have wifi always on, connecting to different networks through the day and no issue, no slowdowns and great range. Maybe you should see an service center.
Sent from my GT-N7100 using XDA Premium 4 mobile app
I had it on 4.1.2 but not on this one. In fact I didn't use Wifi because of that and the huge battery drain. I can now use it again ase both problems seem to be solved

Maybe it has to do with the internet router?! I had the same issue with galaxy s3 a year ago. But i have changed routers aswell so it has to be a combination of router bands/model/speed etc.
But since it works with CM10.2 custom rom, it is likely the wifi drivers on the phone that is somewhat incompatible with my kind of router...
You know that you have a option in wifi defenicions to switch between networks if wifi is weak
