I have two wifi networks in my house, but is one blocking my computer?

We (two roommates and I) have two wifi networks set up in the house and I usually like to connect to the faster one closest to my desktop. Today that wifi refuses to connect. Keeps getting stuck on "checking requirements" and then won't connect at all, going back to the network selection panel. The other network is working perfectly fine which makes me think one of my roomies is blocking my IP on the good network. Any way to confirm if this is the case?
I have reset the router a couple times, reset my computer, re-installed network drivers. Told my PC to forget both and re-entered the passwords, they haven't changed.
