‘169.254.X.X – Invalid IP Config’ Error Solved in 4 Verified Solutions

169.254.x.x is a private IP addressing space reserved by Microsoft, which it assigns automatically to your network adapter if the adapter cannot obtain an IP address from the DHCP server. Since the address is assigned directly by Windows itself, the issue could either reside with the network adapter or with your router/modem.

In this guide, we will troubleshoot the issue to diagnose the cause and then fix it. Since the issue could be originating from the modem or from within the PC, we will start with the PC.

Here are a few methods that will fix this problem. Method 1 solves the problem almost all the time so try Method 1 first. If it doesn’t solve the problem then go to Method 2, 3, or 4.
