Thanks for the response.

This is a computer hooked directly to the Bright House modem.

It worked great two weeks ago at the installfest, where I installed a
15Gb drive, and put Mepis on it.

Hoping ot get over there when they get home tonight after 7pm.
Depending on outside circumstances.

Then, I will report back.
