Occasionally, I experience some network latency and packet loss through my ISP, Comcast. When this happens, I let them know about it - and you should, too.

Before you do that, though, there are some things that you should do, as dumb as they may sound. They *will* help you get through to your ISP.

Reboot your computer. Reboot your router. Reboot your modem. (For the last two, unplugging the power cable should suffice; don't forget to plug it back in.)

Finally, you should gather some data to give them. I like to do this by setting up some pings to places in different geographical locations. I've written a script (tested on Linux and FreeBSD) to get this ping party started. FreeBSD users may have to change the interpreter to #!/usr/local/bin/bash first.

Here is the script:

#!/bin/bash
