I'm trying to configure a new router (a Linksys WRT160Nv3) with DD-WRT. It seems that no matter what the settings, DNS lookups fail. I can't ping anything outside my network (I get an
unknown host message), can't connect in a browser, etc.
I've tried matching the settings in DD-WRT exactly (I think) to the settings for a WRT54GS I have running DD-WRT (which is currently working fine), but to no avail.
I've tried explicitly setting Google's DNS servers (18.104.22.168 & 22.214.171.124) as well as the OpenDNS servers.
What can I do to further troubleshoot this problem? I'm not extremely familiar with networking in general and especially diagnostic/command line tools that would be useful in this situation.
