I'm in the same boat but with my whole network..
I had everything working and then I had an "upgraded modem" arrive today.
I followed all the steps to get the modem online and had a bit of trouble.
I called tech support and they finally got me online, yay, but now my printer and the other PCs on the net are gone!
Worse yet I have to print my
irs extension forms and sign them before leaving for the EU. I have 2hrs left until the cab shows up, and the nerd next door isn't home for another 45mins.
I figured I'd do some searches but I'm not finding much since it's such an open ended problem and I don't want to lose my connection to the net trying.
:P
