WNDR3800 - No connection on DHCP (Wired) on 1.10.0

[sxrv]

Hello,

I don't know what's wrong with my setup. My router lost it's gargoyle settings recently so I chose that time to upgrade from 1.9 to 1.10. On the first attempt there was some issue with the wireless or something where it couldn't be configured, after a second flash it actually decided to work.

I'm having a weird issue right now though where I can't get DHCP address from my ISP though. I'm on fibre and all I need to do to get connected is set my router to DHCP. When I hit DHCP renew I get these errors in the log.

What's more confusing is that if I plug in a spare Billion router, that connects to my ISP using DHCP, then I have my Gargoyle router connect to the Billion VIA DHCP and there's no issues. And the release and renew buttons work.

upgrade via "preserver" setting?

Either way fail safe reset or re flash and start again.
