Windows 10: DNS not working over DHCP on Windows 11 PC

Hi I have an issue with DNS on my Windows 11 PC.Yesterday DNS stopped working over DHCP after disconnecting from VPN - now I don't have internet access, cannot ping any of my devices in my home network by IP, but pinging e.g. 1.1.1.1 works. Since yesterday I have tried everything to make it work again like resetting network settings, restarting computer multiple times, restarting modem/router, flushing DNS and registering it again, nothing works except setting DNS manually.All devices on the same network works just fine TVs, smartphones... including 2 other windows 11 machines.I have 2 netw

Perplexed on no internet with DHCP DNS, but full internet with manual

The first screenshot is as it should be with both DNS and IP set to DHCP, and nothing in the advanced DNS settings.

This screenshot is what I had to change back to manual DNS otherwise I had no internet to post this reply.

ADDENDUM I just found the problem I had IPV6 disabled but as soon as I enabled IPV6, and with IPV4 DNS and IP set to DHCP, everything worked, so I'm guessing that IPV4 DHCP DNS isn't working, but IPV6 DHCP is working and windows is using IPV6. Oh and my router is the:- D-Link Amplifi HD Media Router 2000 DIR-827

 

DNS assigned by DHCP not working

Hi,

5 days ago my wifi connection stopped accepting the assigned DNS over DHCP. I'm not aware of making any changes to the configuration that could have led to this problem, there was one windows update relating to flash and the malicious software removal tool,
but no others since the problem has occured

Despite the network the adapter properties being set to "obtain DNS server address automatically" regardless of the network I connect to and the settings issued by the DHCP server, the DNS on my computer is set to 192.168.1.1. (other computers work fine)

I have to manually assign the correct DNS server and change it each time I change network

does anyone know what is happening?

Thanks

OK, But there is no DNS server listed when you use DHCP. Make sure in Windows that you have the Obtain DNS Server automatically checked. Then press the Advanced Button, go to the DNS tab. If the Manual DNS address is listed, press the Remove button And the rest of the settings looking like this
