After the ARC S upgrade to Android 4.0.3 the wireless can't find any network at all.
I tried ther restore of settings, then it worked once.:smileygrin:
But as the data connection was not working anymore, I have reconfigured the mobile data connection and after that the wireless doesn't work once again. 
What to do?
Thanks
Marco

I'm afraid that I have to wait for Sony prompt resolution ...
Yes, this is still being looked at and unfortunately I don't have any news about it yet.
