WiFi hardware broken?

Hi,

I thought I had messed with my OS, so I needed to flash the phone. I flashed it already ~12 times in the last 2 days, but following situation still occurs.

When I want to connect to the internet and open the dialog, spontaneously after an uncertain amount of time that could be 5 minutes, the list of networks is shown, just to disappear soon again after a few seconds. When trying to connect it fails "There is something wrong with the network connection".
alternatively, the phone just restarts when it opens the network list dialog.
in rare instances the network connection can be established, just to lose the connection soon or reboot.

please, how can I check wether the wifi module is broken? I still hope there is something else wrong, e.g. error in the flashed image (unlikely, I used it successfully already about 5 times)

I found that dmesg output, happening very frequently:

Code:

Did you try on other accesspoints?

Thank you for your reply. Yes, I did, same effects.

Re: WiFi hardware broken?

Sounds very much like a hardware issue.
Could be bad flash memory, bad wifi chip, or, perhaps some wire got bad connection inside.
