2:41 PM - When the "whole" internet is slow

I've been trying to figure out a network problem at home for over a week.  It's difficult because I don't have proper testing equipment.  I just have to guess.  I've narrowed down a few things.

FIrst, ping traffic to the router has been very slow.  It's also a bit laggy to the switch.  Directly pinging other systems on the switch is fast.  I've also looked at the port statistics on the switch and noticed a lot of CRC errors (for a switch) on the router port. The link is only 100/full but flow control was disabled.  I've since enabled flow control and rebooted the switch.  We'll see what happens.  The network cables are all from the same batch of belkin cat5e that I bought with the switch.  I'm wondering if I should buy some cat6 cables for some of the systems.  In theory, it shouldn't matter with the router because it's not running at gigabit speeds.  The fact that the link is slower than most of the network could be a problem though.

At first, I thought it might be the cable connection.  However, the errors in the logs happen infrequently and are common for cable modems.  The upstream signal is a bit high but still within acceptable parameters.
