Wireless Networking

Ok, i realize this might not be the best forum to post this in, but I've never installed a wireless network myself, and a friend of my wants me to troubleshoot hers (she's hot guys, come on!) Anyway, here's the situation:

She's running a desktop with a wireless adapter to a linksys B wireless router, to set it up it says you need a desktop physically connected to it via ethernet cable to set up the router, but the pc and router are far apart, unfeasibly far, and the setup keeps coming up that there is no PC connected to the router, is there any way to set it up with out running a cable PC->router??

This is your excuse you lug your big desktop over and move in for a few days. :) (She is hot, afterall). If you also have a laptop, she doesn't need to know you could have just brought that over.

Alternatively (realistically), the router may not need to be hooked up to the Internet to be configured (unplug the router, move it next to the computer, plug the power back in - sans internet connectivity - and try setting it up). When that is done, move it back over and plug in the cable modem or whatever she has.

Sounds good, i'll try it tonight.
