It sometimes becomes necessary to
manually renew your IP address. If you suddenly
realize you do not have an Internet connection, you can
often simply right-click the computer icon in the task
bar near the clock of your XP desktop (If this icon is
present).
This will go through a process of resetting your IP
address.But if you do not have
this option, you can go to START>RUN and type cmd.
At the command line type ipconfig /release (or
winipcfg /release in earlier versions of Windows).
Then hit ENTER. Next, type ipconfig /renew
and you should get a new IP address from the router.
If you have a cable modem, you may
want to also renew its IP address. First, go ahead
and release the IP address on the PC, then shut the
computer down. Next, unplug the cable modem for a couple
of minutes, then plug it back in again. Once all
of the modem lights are green, power up the PC again.
It should automatically renew its IP at boot.
Note: If you have a router,
you'll want to unplug it, as well, then plug it back in
AFTER you plug in the modem, but before you power up the
PC. The router will need to supply the PC with a new IP
address.
