Still having some issues with this on my Linksys WRT300N Router. Does the original transformer support N routers encryption? I was only able to get a connection without using any encryption.. I'd like to use WPA but even WEP does not work..
So far I have reset the router and tablet, multiple times; including cold booting the tablet and hard resetting the router to original specifications . Changed the routers IP address, added the tablet's mac address to the DHCP reservation list, changed its reserved IP outside of the 100-150 range, changed the MTU to 1500 - 1492 - 1400, Changed the radio band to standard and wide, channel 6, entered the network key in hex, and any combination of these things and possibly some others I found and forgot along the way.. still nothing works, the connection strength drops to nothing until I "forget" the network and try to re-enter the key again.. I'd rather not set up static IP's if possible.
Edit : Last thing I tried that worked: update your router's firmware!
