I brought a similar issue up in a thread quite some time back, but I've found that this problem seems to be a trend.
Have any of you had trouble using D-Link wireless cards with USR routers and vice versa? I've found that they seem completely incompatible. I've tried using a D-Link card with a USR router and a USR card with a D-Link router, played with every configuration I could find on both items, and never could get the darn things talk to each other.
Talking to tech support is hopeless. D-Link techs are insistant that it's a USR problem, and USR techs point the fingers at D-Link.
Have any of you run into this, and if so, did you ever find a way around it?
