Hello. I have an Archer VR1210v which I used for two months now. It worked fairly good until yesterday, when I've changed my ISP (I am in Italy) and switched from ADSL to VDSL.

Although the DSL is connected and running, the DNS server cannot be reached. I tried to reboot the modem/router, set manually Google DNS, set manually my ISP DNS, enable and disable bitswap (like someone suggested online), I even performed a factory reset. Nothing seemed to have worked. I always get the same error. 

I have read online that this problem is fairly common but there is no definitive solution. 

What can I do? Is there a beta firmware or something that I can try?

I can provide the screenshots of the status page and other relevant parts. Let me know if any other information is needed.

Thanks.
