No issue no fix.
Kernel is responsible for WiFi you can try a different kernel.

Usually when I have 3g or wifi problem, I do simple reboot or battery pull. Then it fixes the connection or downloading problem. I have not had any problem with MIUI for few days so far.

[Q] Has anybody realized there is a problem w/ setting call forwarding when on WiFi?

When on cellular data, this works fine. But when I'm on Wi-Fi, it doesn't work half of the time. I've tried different modems, and the problem is always there. Also, I realized that it takes the phone three times longer to send a text message when on Wi-Fi than it does on cell network. Anybody experiencing similar problems?

Edit: forgot to say - lack of cell coverage is not an issue. H+ available where the problem occurs.

S3 Signal Issue

Just wondering if anyone can help with a 3G issue I appear to be having.
I generally get great mobile internet signal, but today it keeps dropping out. If I select GSM only or WCDMA only then I can maintain fast mobile internet speeds, but if I select GSM/WCDMA (Auto) then my signal drops to 2G.
Signal in the area is fine for everyone else on the same network.
Has anyone else experienced this or know how to resolve it?
Thanks in advance

Funny thing is, i have the same problem.
I got great mobile signal on stock ICS, full bars. Until i flash another ROM, ARHD 13 to be exact.

Try updating to JB if it's a software issue that should sort it.

I think i found the solution.
I'm on ARHD13, with Phenomenon kernel. I flashed other modem, for my region, that is LH1. That's when i got terrible mobile signal.
Then i went back to Phenomenon thread, and found out that he's using XXDLIB ramdisk. So, i flashed XXDLIB, just to test it out.
And it worked! My signal bar is full again.

GPS lock ?

Can GPS lock issues be kernel related or strictly a ROM issue?
Sent from my SGH-I777 using xda app-developers app
They could be either, but unless a significant number of people are reporting the same issue with either a ROM or a kernel it is likely something to do only with your specific phone.
You can change the setting on stweaks using siyah kernel.
Or download an app to do that.
