Just got my 770 Saturday. Connects flawlessly to my network (D-Link). Works great except.....when going to other parts of town, my device sees other open/unlocked wi-fi networks, connects to these networks (per the connection manager), however, when trying to surf the web, states "network problem". I am unable to surf the web. This has happened to atleast 30-40 wi-fi networks. Any suggestions ? Cheers, Greg
