So, I bought a new router, and I have had some issues getting it to work properly. I myself work in IT, but not specifically networks, so I wasn't sure if I would be able to grasp this potential solution. Currently, the router is handing itself out as a DNS server, to enable takeover of web queries in the event the network is down, and send you to the router login page. However, after a couple hours of use, it stops forwarding DNS queries to the set server.
Router is a Netgear Nighthawk X6 R7850. I just want to know if OpenWRT would fix these issues, and if my router is compatible.
