Hey, I've had this phone (9000 bold) since Mid-july 2012, and the wifi was working fine and stuff, on 31st, I wanted to check if I can find wifi in my friend's apartment, I found out he's got wifi, 3 green bars, he gave me the password, I connected but, I couldn't use anything (I use facebook app latest version, jmirc latest version when i'm connected to wifi), not even browser, I turned off mobile network and it couldn't connect. Facebook app said I'm not connected to any Wifi network, but I was..It worked ~1 month before that, after that I haven't honestly tried to find any wifi network.
I've recently changed battery because the old one was dying (would go down to ~70% after 15-20 minutes of music on headphones, with mid loud volume, 4-5 bars) so yeah..I tried to remove the profile, reset default wifi settings etc..nothing helped :<
I haven't tried installing an update to the os I have (last time I updated was around october..) so yeah..any help will be appreciated
