I've been having a similar problem with my 770. This problem always occurs in public wifi hot spots. If, when trying to connect, the 770 says that it has make a "local link" connection to the WiFi network in question, it will never allow access.

Yesterday evening we were at bar/restaurant in New Brunswick, NJ (Stuff Yer Face) and I attempted to get on line. On my first try, I connected thru the "local link" and, of course nothing worked. There was a question mark next to the WiFi symbol at the top of the screen. Then I tried it again, and it connected without indicating anything about local link. The connection worked fine. I was able to surf and get my email without any problem.

Does anybody know what's going on here?

Thanks
