[Ondrej_CZ]

I can't turn on wifi on my phone. When i want do it, it write just "error". It's happened today afternoon. I also can't turn on bluetooth. Any ideas what i can do? I think that's software problem, but i don't want lost everythink in my phone. It just at 2:00 pm work normal, but 2 hours ago, when i want connect to wifi, i had this problem. Thanks you for every idea. Sorry for my bad english, i'm from Czech republic.

Sorry to bring this up again, but does this update thing solve the Sola's problem with connecting to certain wi-fi channels and frequencies?

I'd really like to know as this is a major setback for people relying on wi-fi hotspots, which as we know are not ours to configure and mess around with unlike your home router. Not to mention that people usually leave their wi-fi channels on 11, which I think is the default factory setting for routers.

Or is this a hardware problem all together which cannot be solved and Sola users are basically screwed?

i don't think its a hardware problem. My sola has been working fine with the hotspots all around my campus when its running GB. since i 'upgraded' to ICS though, the phone has never been able to connect even once to any of those hotspots.

Xperia sola, P, U wi-fi freeze FIX

Many of Xperia users on ICS experence an annoying bug when wi-fi hangs and doesn't turn off, unless you reset the phone, and blocks the use of 3G data. I found temporary solution until Sony fixes this permanently. In order for this to work, your device needs to be rooted, i.e. allow access to system files and folders for select applications. Google how to do it.

Heres what you need to do when rooted:

1. Install ES Explorer from Play Market (free)

2. Turn off wi-fi

3. Open the explorer, go to /data/misc/wifi and delete wpa_supplicant_bgscan.db

4. Turn on wi-fi (this will generate a new wpa_supplicant_bgscan.db file)

5. Go back to /data/misc/wifi, select the new wpa_supplicant_bgscan.db, and change all of its permissions to "read only"

6. Enjoy your bug-free wireless!

Apparently this file accumulates data which eventually causes wi-fi to freeze, so making it unwriteable fixes the problem.
