wzr-300hp DNS timeouts

[mattglet]

The big issue is that I constantly have DNS timeouts when using my wzr-300hp router (DD-WRT version "v24SP2-MULTI (07/09/12) std - build 19438"), both wired and wireless.  I haven't figured out if this is time-based, or something to do with the connection, but I will get DNS timeouts for a few minutes, then things will clear up and I can browse again.

 

Does anyone have any idea what can cause this, or what settings I can check/verify?  I use Comcast as my ISP, and have switched DNS to OpenDNS to see if that fixed it... it doesn't.  If I connect directly to my cable modem everything works as expected.

Do yourself a favour and take a screenshot of your WebUI for the router, and post the relevent DNS settings that you've put into place. Have you ever had great connectivity out of this unit, or has it always given you this issue?

Here are screenshots of my WAN and LAN settings.  This device has been working just fine for over a year, and only recenly starting doing this.

Honestly, you need to drop the last DNS.
