Only some websites will open - Ubuntu

I have just installed a fresh copy of Kubuntu 7.04, and I'm having
some unusual behavior. Only some websites will open. I have tried
with firefox, and Konqueror, and the results are the same. For
example:

google.com opens. And fast too...speedy
slashdot.org will not open
vmware.com will not open
ibm.com will open

At first I thought it might have to do with DNS settings, but I
manually changed the DNS server entries and it had no effect. DNS
seems to be working anyway. In firefox, it finds the site, loads the
title, the icon for the site, and then states "Transferring data from
[blah]..." in the status bar. In Konqueror the transfer rate at the
bottom immediately drops to about 100b/s, then disappears entirely.

I am behind a Linksys RV082 router, but I have had another Kubuntu
7.04 system behind the same router with no problems.

I MAY have had this issue with this computer before, so it might be a
driver issue, but I am no linux pro, and I have no idea what steps to
take to investigate or fix it. That is only a guess though.

Any help will be really appreciated. Thank you in advance!
