I have a similar problem. I can connect at my WEP protected home and work computer. However, when I pick up unprotected networks ANYWHERE else but those two locations, the 770 says I am connected but when I try to connect to a Website, I always get the dreaded "network problem" error. I know it's a common problem from reading the posts here, but, I still have not seen a good solution to this problem. Anyone figured out how to fix it?

I can normally connect to my Netgear at home, and yesterday was able to connect to a Linksys public access router. However, a couple of days ago I was surfing from my couch, and it just up an quit ... in the middle of downloading a web page ... with the dreaded "Network Problem" message. I checked my PC, and it still was connected, but rebooted my cable modem and router just in case. Disconnected the IT, then reconnected (a couple of times) and then just as mysteriously the connection came back.

Curiouser and curiouser!

Let me tell you after spending hours yesterday with out being able to make a connection to my Router (every configuration you can imagine) I woke up this morning and changed the wireless router from Channel 11 to Channel 6 and everything work. I hope this helps someone .
