First, I'm not sure if this is the best forum for this question, so if it is
not, please advise.

I have a general question re network settings under Vista Home Premium. On
occasion, during busy times of the day, my cable modem will indicate that
the connection is lost. If I manually unplug the power cable to the cable
modem and router, wait until 15 or so seconds, and reconnect the cables, I
can usually suceed in obtaining a connection. I assume the computer looks
and finds a new address from my IP.

Under Vista, using cmd.exe (elevated), I tried ipconfig /renew but
received the following message - An error occured while renewing interface
Local Area Connection : unable to contact your DHCP server. Request has
timed out. [end quote]

My question, apart from manually disconnecting the power cables from my
modem and router, is there any other way to obtain a new IP address from my
provider when the 'circuits are over loaded'?

Thanks, Dave Horne
