Or probably the router wasn't set to use WEP
And use mac address for your security...
Try to use that USB WiFi.. see if its working..
I'm using SMC wireless router with SMC wireless card. Although my connection strength is excellent, I still cannot get to the internet. When I try, I get the message the page can not be found. I spoke to the SMC rep, (very helpful at times) and they told me to delete the Network Bridge because that was preventing me from accessing the internet. Tried it but that didn't work. I have WEP enable and another computer connected to the internet via wireless USB card but my laptop can not get to the internet. Please help me with my connection. This all occurred after I enabled WEP and the security key code.
