Try to flash a new modem (I suggest you DL8).
Note that you have first to root the device before flash it with Odin.

having quite a serious issue with the vibrant wifi

I have this issue with wifi. It's that when I'm at home, it won't connect at all to my wifi all I get is obtaining address and eventually unsuccesful, yet occasionally it does work. Then, when using other wifis, turning on wifi does make it connect and show the icon in the notification bar, but still, it won't always work. I try to get into the market but it says no network or something like that. Tried most web browsers, nothing works too. What can I do? My phone is rooted and flashed with bionix fusion rom, evn though this problem sometimes happened even with stock firmware, rooted and not rooted. What can I do? Can't really get a replacement because i bought it from overseas. HELP!!

Some routers are a tad dodgy, so it may not be the phone at all. Since we dont know what type of router or what sort of connection environment your in (how many wifi connections it's handling, etc...) it's hard to say. Still it's easier to replace a $30 router than it is a several hundred $$$ phone.
I said in the post itself that I tried more than one wifi aka router, most of them connected to a laptop and my phone at a certain time. Therefore I doubt the issue is the router. I think it's a bug. Is there no fix for this?
This is kind of a shot in the dark, but have you tried putting the phone in Airplane mode and then restarting the Wi-Fi? I've found that the cell data connection can sometimes interfere with my Wi-Fi.

I would put my money on the router, I have not seen anyone else complain about this who is running bionix. So a bug within bionix, I'm going to say no.
HOWEVER!!!!!! I had the same problem for a while. I have AT&T uverse and there 2WIRE router is total crap... I had the same exact problems as you PLUS it would not connect to my mac mini for more then a few seconds. I hooked up an older router I had laying around and BAM no more issues.
I got the same problem, but my phone is not rooted or flashed. Must be a system/software problem.

WiFi crashing

Hi guys,
I'm running 4.1.B.0.431 pure stock (no root/never flashed anything) firmware and I'm experiencing this bug - every time I try to connect to any (and I mean ANY - I tried tens of WPA2, WEP and Open networks), it will connect at first (with good signal strenght as I always tried it standing next to the router if it was a problem with signal) but immediately disconnect and then won't even find that network that I connected to before, I have to wait a minute or two to find it again, but then the procedure repeats.
Can anyone help me ?
P.S. : there is no problem with router as I tried changing every single option on my home network, upgrading firmware of router and entering my MAC,nothing helped.. I also tried lots of other networks so I assume the problem will be in my phone, but - where ?
Thank you very, very much.

not yet, but I don't want to lose my apps and don't have any other backup method - I would go for that only if it was really the solution.
You can backup your apps via android assistant.. Also you can backup contacts via Google about..

Xperia U: very weird wifi problem

My girlfriends XU is acting up ultimately weird..
Since some time we have this problem:
Wi-Fi only works for about 3 minutes when connecting to a wifi signal, yet the wifi signal icon indicates as if it has a good connection. The only way to regain connection again is to reboot, but then the same problem repeats itself, after a few minutes wi-fi is not working anymore. Also in the wifi-indicator the "send" arrow works, the "receive" arrow doesn't.
Basically if you want to discover a new wi-fi connection you need to reboot the phone also, because otherwise the previous connected wi-fi signal remains (it freezes as stated before after about 3 minutes).
Tried a factory reset already.. Didn't work. The phone runs the stock sony android 4.0.4.
Any idea's ?

Alright, sry then, can't help any further...
Does it happen with all routers or only with your router?
Have you tried to repair using SUS?
Someone one the official forum had a similar problem and it was fixed by repairing the phone using SUS.

[Q] WiFi won't connect (logcat included)

Hello!
My Phone has some Problems with Wifi since this morning, happened out of the Blue.
What the Problem is:
Cannot connect to any network, it says wrong password, even on open networks.
When it says "Connecting" the Wifi Signal Strength goes from Full to Zero.
What I tried to fix it:
Ofc Restarting Router, changing channels (also 2.4ghz + 5ghz), but that didnt seem to be the Problem. All my other WiFi Devices would connect without a Problem. And I was literally standing right next to the Router. I mean it used to work fine for the last 1.5years...
I was Running CM 10.2 Nightlies + CWM Recovery so I thought there might have been an Issue there.
First I wiped everything clean and reinstalled the newest nightly. Still the same problem.
Then I reinstalled Stock Recovery and the latest Stock ROM. Still the same problem.
Tried it with turning off the Power Saving Mode (*#0011#) didn't help.
Now I know you guys are big on LogCats so i attached mine here. I saw some E/ concerning Wifi but I don't really know how to make sense of it. So if anyone here wants to take a look at it knock yourself out.
Edit: its too big as an attachment so here's the dropbox link: https://www.dropbox.com/s/btqr0l8t0zm573l/logcat.txt

Yes i can see the networks just fine, but as soon as i connect the signal indicator goes to zero and it gives me the error
another thing that might be related is that i also cant pair any of my bluetooth devices anymore, i can find them, but pairing wont work
Same problem bro, am an old android user who went to iOS 2 years ago, and went back to android 10 days ago xD
first thing to do was getting rid of any rom and flash latest cm ! and buff ! can't connect to any wireless network, i flashed stock back and everything went fine, it just won't work with cm or aokp and i wish i know why !
it sems a sort of kernel config issue conserning wifi ...
how could it be a kernel issue? i tried cm and stock and both wouldn't connect.
but oh well, on monday i brought the phone to my provider, on tuesday i had a new replacement waiting for me so its all good
i think the wifi/bt chip was slowly deteriorating. BT Audio would sometimes crackle/stutter to the point where you couldn't understand anything, and that across multiple paired devices and ROMs

Wifi stops working after a while

From since two weeks ago I am having issues with the wifi in my phone. It happens that whem I am browsing Internet or watching videos with the Wifi on sometimes the phone stops connecting to the Internet. It cant connect, but the Wifi is still working, since the icon shows that it still is activated.
Also, when I restart the wifi conection, it starts working again, and again it stops after a while, which can range for two minutes to one hour.
This started to happen when I flashed Ultima ROM 16.0, but kept happening with oher ROMs I flashed, even with CM 4.2.2. I suspect that this is a problem of the XXUGMK6 modem. What do you think?

Im using the same modem, but different ROM ( S4 Revolution ), I don't have any issue with Wifi. Just check with your wifi or restore your stock ROM and check the wifi

Thanks for correcting me. Then what could be the problem of his wifi. How it can be solved ? You have any idea
No but multiple identical posts may give an answer .
Mmm, I dont think this is a kernel issue, maybe because when I reinstalled the CM 10.1, it used cyanogenmods stock kernel and it still gave failures. So all is left to two options: the modem or the Wifi router. What do you think guys?
As a kernel, I use Boeffla Kernel 5.1 beta 7, for Sammy 4.3
