I just got verizons new fiber optics internet, and they gave me a modem/router in one tower. before i could connect my nintendo ds to my old lynksis router, but now it asks for a WEP key, i enter it, but ... it says its not a compatable WEP key for the ds, i called support and all they said was ill have to find out the WEP key numbered 1 thats in my router but theres only one on the router its self, how can i find this out?
