does your NDS detects the d-link router ?

try manaul ip setting on nds lite and the router.

this happen to me when I try to hook up my 3com router.

my nds lite detects my 3 com modem. however the router has already givin an ip (by dhcp )

so I set my router with that IP fix on my NDS lite.

and I have to set manually IP (which given by the router) in order to go online..

wierd... haha but it works.. (for me though)
