Windows System IP Address Conflict on Network

When Windows detects an IP address conflict on a network, you cannot use your Internet connection or you may experience an extremely poor-quality signal. Fortunately, this problem can fix itself or require minimal computer skills to correct.

Problem

IP address conflicts occur when the Dynamic Host Configuration Protocol (DHCP), which doles out IP addresses, gives the same IP to multiple computers. IP addresses are a computer's identity on the Internet, according to Webopedia.

Causes

The most common causes for an IP address conflict are the DHCP assigning a static IP address to a computer but not taking the IP out of the pool of variable IP addresses, or a computer going into sleep mode and the DHCP server assigning that computer's IP to another one, according to Online Tech Tips.

Fix

Most routers have DHCP enabled, so the problem should eventually fix itself, according to Webopedia. You can also enter IPCONFIG /RELEASE and IPCONFIG /RENEW in a DOS command prompt. Restarting your computer also resolves most conflicts.
