Today everyone can make a dsl router/modem, and ISPs when they give you equipment they want it to be cheap. I saw exactly the same problem on cheap dsl routers, I don't have enough knowledge to debug it, or to be sure if it is safe or not, it worked for months with no issues, no reboots ..., one day it stopped working/resolving hosts, and its dhcp server config doesn't allow "forwarding" of DNS servers from WAN configuration, or manually setting one which will be given to the dhcp "clients", so there are two ways, it can work as a proxy (send its own IP as DNS server to clients), or it doesn't provide DNS, so you need manually to configure each client. If you restart the router, it works sometimes for few hours, sometimes few days, but it will fail again randomly. The only worrying thing is that it worked for months without an issue.
