There are two problems you are going to have unless you buy an

Thanks for all the advice.

In the short term, I decided to buy a WiFi USB card, since
it has to work this weekend, and I don't have time to get
the Dell WiFi card until the next visit after school starts.

I opted for the same brand as the router, assuming they'd
work better together that way, a TP-Link 802.11 a/b/g/n/ac
1200 device (if it works).

Here's a picture of the Archer T4U for about $25 at Frys.
