hi - wondering if there's any way to revive the router from its stroke/coma?

i switched it off (working fine) to test another router. upon reconnecting, all the lights work fine like they should inc adsl(internet) and status blinking quickly like they should.

but nothing connected to wired/wireless seem to be able to communicate (despite lights blibking like they're talking to the router).
no internet.
no voip.

pressing 10.1.1.1 - nothing!!!!

retarted both computer and router 3 times. nothing.

help? any ideas? now using a slingshot provided single port dynalink which is fine.
