This has been confirmed by lots of users, and affects Nexus S users either traveling to Europe or Asia or those living there. I live in Norway, and a lot of WiFi networks are set up on these channels. In effect, this severly limits the number of networks I can connect to. It could be both an issue with Android and the Nexus S hardware.

I appreciate if those of you who'd like Google to focus on this to star this Android issue, in order to direct attention to the issue. Thanks a lot!
