Why can't I see internet servers? I have great internet!

I am on a LAN, at East Texas Baptist University, T1 running directly from my apartment. My internet is screaming fast for everything else I do, but when I open quake, I can’t see any internet servers. Until about a month ago, it was just fine. I was playing often. I recently downloaded Spybot, a software that finds and deletes certain spyware cookies, and I have been deleting everything- do you think this could have something to do with it? Also, if there’s anything I should do with my internet options, could you let me know?

Thanks!!
