I'm making small progress. While my Samsung netbook seems to be a lost cause, the Sony laptop seems salvageable. I can get brief moments of connection. When pinging the server during these times, I'm losing 3 out of 4 packets, but getting one returned. There is SOME connection between my Linksys gateway and the Sony laptop, connected through my Asus access point. The signal seems dependent on location though, and moving it even 10 ft away from the Asus degrades the connection severely.
