I have a comcast cable modem (Motorola SBV5220). I connect to the internet on 2 different laptops. Suddenly, one laptop (Windows XP) cannot connect anymore - I get an error that it cannot connect to the IP address. When I try to repair, I get the unable to renew the IP address. I don't think the problem is with the modem, because when I connect the network cable to my other laptop, it connects just fine (and thank goodness it does, because I'm using it to type submit this question!)
My attempts to fix the problem:
I checked the modem cables -- all connected
I unplugged the modem and removed the battery for over 5 minutes.
I ran ipconfig/release
I rean ipconfig/renew - I get this message: An error occurred while renewing interface Wireless netowrk Connection: unable to contact your DHCP server. Request has timed out.
I also tried this:
In Control Panel, double-click Network Connections, right-click Local Area Connection, and then select Properties.
On the General tab, click Install, select Protocol, and then click Add.
In the Select Network Protocols window, click Have Disk.
In the Copy manufacturer's files from text box, type c:\windows\inf, and then click OK.
Select Internet Protocol (TCP/IP), and then click OK.
I'm not very technical, and I have no idea what to do next. Thanks for your help!
