Resolving an IP address conflict

Discover how to troubleshoot an IP address conflict at a client site involving DHCP-assigned IP addresses.

One of my clients has a few employees who are getting an error message about IP address conflicts when they try to connect to the wireless network. What could be causing this problem?

The most common reason for this with notebooks is that they have been in sleep mode for too long, and their DHCP-assigned IP addresses have been re-assigned to other computers while they were sleeping. You can either use static addressing, or set a longer timeout value in your DHCP server.
