Tried to edit Title to read: Changing DNS server
I have an Archer VR2800 running in DSL Modem Router Mode. All is great, however I having problems changing my DNS server from 126.96.36.199 to my Raspberry Pi Adguard on 192.168.1.13
The pi is working correctly, I can set my PC's connection to use it as the DNS server but if I change the DNS server to 192.168.1.13 on the modem, the modem reboots and changes the LAN settings and the local modem IP address, from 192.168.1.1 to 192.168.0.1 and therefore all my locally attached devices are messed up.
Why can't I just change the DNS server and all the other settings remain the same? I didn't have this problem with any other modem I'v used.
