I have this exact same problem too, and it only seems to affect Windows machines.

It appeared before the current firmware, maybe about 2 firmware versions ago, although they have been released close together.

Basically, if I use the router's DHCP setting and not modify it per client, therefore accept it as the DNS resolver, Windows machines frequently have DNS timeouts/resolution problems.

 

Just retrying several times will eventually overcome the DNS issue, but it's frequent and annoying and will interfere with anything automated or queued

 

Interestingly Linux clients do not have this problem even when using the R6400 router for DNS resolution.

    just to update, I have a few times gotten dns issues on linux and Android devices since the recent firmware releases. But very rarely in comparison to Windows.

     

    With the router acting as the dns server, I assume is just forwarding all the requests to my ISP (whose dns servers are listed in the Advanced > Internet Port section)

     

    I don't know much about this, but is the router caching (the TTL in DNS) and is there an issue with this?

    I am having the problem as you state. Probem is; I have no idea about DHCP or DNS settings. I have NEVER had a router problem until this last Netgear "update". If I could go back in time, I would.

    Thanks for your help!

      You can downgrade. Simply go to the support site for your device, click on downloads, and then "view previous versions". 

      Once downloaded, extract it, and follow the manual firmware update process but use the downgraded version of the firmware and not newer. 

      Anytime you downgrade, I'd recommend doing it over a hardwired connection.

        I could not find "view previous versions" for the R6400.
