I have a friend with a TPG NBN service who is using the Huawei HG 659 and would like to change the default DNS server to open DNS.
How do I do this? Screenshots would be greatly appreciated.
It should be on the DHCP Server settings under LAN Interface
After you log in the modem's GUI
Go to Home Network Tab
Then go to Lan Interface
Then look for DHCP Server and just manually configure the DNS Server
