No issues here either. I've had no problem connecting to WiFi at home as well as in customers' offices, hotels, airports, you name it - in the UK, in various European countries and in the US.
Only things I can think are what Mitch suggests or that there's a hardware issue with the WiFi radio in your phone. May be worth contacting Google Support, see if they have anything to suggest - just make sure you back up everything on the phone first because the first thing they definitely will suggest is a full factory reset.
