Windows XP network can’t acquire DHCP address

Have you gotten in a situation where you have a network cable plugged in, and the connection light is ok indicating a good connection, but you can’t get DHCP? The symptoms in Windows is that you can’t acquire a network ip address and selecting repair network does not fix the problem. I have notice the following causes:

1. Your router is holding on to the lease for your computer. Try disconnecting the cable and see if the router will create a new lease.

2. If this does not work, then shutdown the router for a minute and then restart it. This should clear the lease.

3. Sometimes if you have bad ground, you could get enough noise that the connection seems to be OK, but you can’t acquire a lease.
