I'm trying to access the internet with my iPAQ 2215 PDA using a SanDisk Connect-Plus Wi-Fi 128 MB card and a Linksys WRT54G wireless broadband router.  The green LED stays on continuously, the PDA shows that I'm connected, the server-assigned IP address comes on correctly, and the Ping test shows connectivity, and yet when I try to use Internet Explorer, all I can get is the message "This page cannot be found"  This problem has continued despite removing and reloading the card driver and setting everything exactly as told by SanDisk tech help.  I had a similar problem when I first purchased the setup.  I finally got it to work after several hours of "tinkering".  (I don't know if it was something I did or if it just finally started on its own.  After several hours it all becomes a blur.)  Anyway, it worked fine for several weeks, but then suddenly, and without my making any changes in anything, I started getting the old page-cannot-be-found message again.  I've run out of things to try, and suspect SanDisk help has also.  Has anyone in the group had similar problems or does anyone have suggestions?  Thanks in advance.
