Cannot renew IP address

I realize this is a Windows 7 forum, but my problem began when I attempted to install Windows 7 on a 9-year old Toshiba laptop. Not being able to find operable drivers for this no-longer-supported laptop, (despite MUCH help from Maxie) I reinstalled XP using the Toshiba Recovery and Applications Media.

Windows XP - restoring of original system software. Cannot connect to WiFi - laptop reports "Acquiring IP address" and then "Renewing your IP address" then reports limited on no connectivity.
When connected with an Ethernet cable, same messages appear. In each case, the computer reports that it could not renew the IP address. Downloaded and installed latest XP drivers from manufacturers' web sites. The Device Manager does not report any driver problems.

When I attempt to release the IP using the "ipconfig /release *Con* from the CMD line, I get the following:
No operation can be performed on Local Area Connection while it has its media disconnected.
No operation can be performed on Wireless Network connection while it has its media disconnected.

I am confident the router is operating since I can connect with my iPod and surf the web, download e-mails. Appreciate any assistance you gurus can provide.

I would try power cycling the router. Unplug the router and wait about a minute or so then plug it back in a let it reboot. See if that will solve the issue for ya. If not; do it again; only this time unplug the modem as well and wait about a minute then plug it back in. see if this helps ya out any. Oh yes; even though you say you can get emails etc; I would still try this as there may be something in both the router and or modem that needs to be reset that is not allowing the ip to be renewed. It also could be that something is amiss with the network drivers for xp.
