In simple terms, the Dynamic Host Control Protocol (DHCP) is one way to automatically assign IP addresses to devices on a network. But after the 24H2 update, this process appears to be broken. The issue could also be that while the DHCP server properly assigns IP addresses to devices, the DHCP server itself has a problematic address.
In this article, we show you some tricks to solve the problem. If these tips don't work, you can try reverting to a previous Windows version.
Tip 1: Query the IP address again
Open a new command line session as administrator in Windows 11. (You can do this by right-clicking on the Start menu, then selecting Terminal (Admin) in the context menu.)
With the command line in focus, enter the following two commands to relinquish your current IP address and obtain a new one:
ipconfig /release
ipconfig /renew
The chances that this restores your internet connection are slim, but with a bit of luck it might work. But despite slim chances, it's a relatively simple solution so it's worth giving a try.
Tip 2: Set static DNS servers
As DHCP no longer works, you can instead manually set IP addresses to use for DNS resolution.
To do this, open the Start menu and search for View network connections,
