LinuxQuestions.org - Erratic network performance / pinging

I just brought my desktop/fileserver down to add some more memory -- a stick of 512 to the two sticks of 256 for a total of 1 gig.

After bringing it back up, my network is exhibiting some weird performance issues. I don't think the memory upgrade is the cause, but I'm mentioning it because it's the only thing that has changed configuration wise.

I'm getting very erratic ping responses. It could be some local weirdness with my ISP, but none of the other computers are acting this way on the network.

Here's an example:

Code:

rtt min/avg/max/mdev = 11.426/313.365/857.339/302.692 ms

As you can see, the ping is fluctuating from 11.4 ms to almost a second.
I noticed this first when attempting to play a multiplayer game and I started getting "connection interrupted" warnings.

Any ideas?
