I just got my router up and running today (latest RMerlin FW) and I'm having intermittent issues with name lookups failing.
The router is using my ISP DNS servers. DHCP was originally setup to pass the router's address to DHCP clients for DNS lookups.
Every so often, a lookup fails. For example, I couldn't open www.speakeasy.net in my browser and attempt to ping from CLI would result in an "unresolved hostname" error.
However, in another terminal session on the same machine, I can ping www.speakeasy.net by IP address and I can also ping it from the router management page itself.
Changing my DHCP settings to pass my ISP DNS server address to the DHCP client fixes the issue immediately.
