Hi guys! I've been trying to get help for this on another website, but they're not doing much... I thought I might post this in a website who has more than 3 tech savvy users! Especially since I need this working in the next three days, or I'll have to put in some time at the library.

So around two weeks ago, I moved into a set of apartments that share three different wireless networks, that were recently installed by Comcast. For the first week, everything worked perfectly- I was able to connect to them, and use the internet. Then, about a week later, I found a Trojan (Trojan.BHO) through Malwarebytes Antimalware- I cleaned that up, and thought that'd be the last of that.

But after doing that, whenever I'd connect to one of those wireless networks, I would be allowed local access, but not internet access. (I don't know if that has anything to do with the Trojan removal.) When I would try and open Firefox while connected to the network, it'd take maybe 3 minutes to actually open, and then it would never load a page. When I tried viewing a webpage on IE, it gave me an error that the DNS Server could not be reached. I ran the diagnostics tool, and it returned an error: "Cannot communicate with primary DNS server. Network Diagnostics pinged the server, but did not receive a response."

And that's the point I'm at now. The person who was helping me earlier was deadset on my problems being caused by a trojan, which may be true. While Googling around, I found a lot of issues with a "6to4 Adapter," which seems to fit what's going on here. (But when I went into Device Manager to disable the 6to4 Adapter, there wasn't one listed.)

My computer is an Inspiron E1505 running Vista 32bit SP1. It's using the standard 1390 WLAN Mini-card. I've scanned through recently, and found no trojans or viruses.

Thanks for any help you guys can offer! I'll try and check with this thread as often as I can.
