Hi Tomas

All the the linksys routers that I have used seem to only want to communicate with other linksys routers only. They all seem to have a statement like the one I copied below.

"The Wireless-G Range Expander is compatible with the Linksys WAP54G Access Point, and both the WRT54G and WRT54GS Wireless Routers."

This may mean that you need to replaced your D-Link with a Linksys for it to work. Read the specifications and do a search for "compatible".

All the best
Dale
