The problem is that router can't get time information when I'm using OpenDNS. Otherwise, when I use my ISP DNS servers works good. I have tried both options under Basic Setup written on the wiki.
Any help or thoughts what this might be causing? Maybe OpenDNS is having some issues with pool.ntp.org?
I use OpenDNS, and have a bunch of computers & routers using pool.ntp.org all the time. Never had a problem. Have you tried some other time servers, like time.nist.gov?
