Sham, can you explain what you mean by "subnet isn't right".

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?
