"turning wi-fi on..." forvever and not in range

[chickenwing]

Hi,

I have some wi-fi issues. I already flashed many times to different versions. Wi-fi connection was always poor. But at some point i can't even turn it on. It just hangs "turning wi-fi on..." but nothing happens.

After flashing sometimes(!) the first time it turns on find one, switches to not in range. So i have to reactivate wi-fi waht ends in "turning wi-fi on..." forvever.

Any ideas what i should try?
Is there a difference in installing a rom directly as update.zip and via cwm?

I would be really happy about some help, becuase without wi-fi it is useless for me.
