Network Speed



I've run into a networking issue on my home network where one box is extremely slow on downloading and just in general browsing. The slow box is a Dell XPS 400 running Fedora Core 5. I have a Dell Inspiron 8600 running RHEL 4 WS which has no speed issues at all. They are both plugged into the same SOHO firewall which is connected into a cable modem. I'm pretty much at a loss, so any ideas would be a great help..

Here are some of the details.
Broadband speed test at Speak Easy shows:
*Core 5 * = Down 11.6 KB/sec transfer rate / UP 41.5 KB/sec transfer rate *RHEL4 WS * = Down 383 KB/sec transfer rate / UP 43.3 KB/sec transfer rate

*Core 5 *=  ethtool eth0
