I was able to download form the Internet with >= 700KBit/s. Then, with
the upgrade to Hardy my network connection dropped to =1000KB/s.

When I get home, I will check the channels and try to install the
backports, though I do think that I already have them installed.

Thanks alot, I will report back when I checked it out!
