Can't get there from here

[wombat_socho]

Ah, the wonders of the Internets. Since the first of the year, I've been completely unable to reach google.com from either of my home computers, and can only reach netscape.com from Cowzilla - which is really damn strange, since both Cowzilla and Deskpro are using the same Time Warner pipe out to the world, and in fact Cowzilla has to fumble for the wireless signal off the router. It's pretty damn annoying. I already tried clearing the cache on Firefox and flushing all the temporary Internet files, but that hasn't helped any. I'd think it was something specific to Firefox, but M$FT's Internet Exploder is having the same problems. Anyone have any suggestions?
