I tried flashing back to 3.10.44-6 but the DNS problems persisted. So I cracked open /etc/config/network to discover I was using Google's DNS servers: config interface ge00 option 'ifname' 'ge00' option 'proto' 'dhcp' option 'dns' '8.8.8.8 8.8.4.4' option 'peerdns' '0' I then tried the OpenDNS servers, but the problems still continued. Finally, I went back to the Comcast DNS servers (my ISP): config interface ge00 option 'ifname' 'ge00' option 'proto' 'dhcp' option 'dns' '75.75.75.75 75.75.76.76' option 'peerdns' '0' Things seemed to be much better after that. I then re-flashed 3.10.48-2 and the problems were still gone. I don't know why all of a sudden trying to use non-Comcast DNS servers became a problem. I wonder if has something to do with IPV6. But I'm leaving things as-is now. On Wed, Jul 23, 2014 at 9:44 AM, Jim Reisert AD1C wrote: > I seem to be experiencing random DNS failures with this version.
