It works! Updated from 50D6. Thanks.

Can someone let me know if I setup my DNS settings correctly? At the top where it says 'Connect to DNS servers automatically', should this be set to Yes or No? If No, then do I need to fill in the CloudFlare server address for DNS Server1 and DNS Server2? Near the bottom where it says 'DNSSEC Validation Method', which should I use (GetDNS, Dnsmasq or Server Only)?

I actually remember struggling with this from a user interface point of view. Once you enable DoT, the base WAN DNS server settings are no longer used, so can be set to anything. But the screen jump was 'jarring' if I tried to hide them when selecting DoT. I'll give it a little more thought if there's a better way to handle it.

Near the bottom where it says 'DNSSEC Validation Method', which should I use (GetDNS, Dnsmasq or Server Only)?
Server only is primarily for Cloudflare where they seem to be a bit more 'tolerant' of misconfigured DNSSEC sites. I prefer to do the validation locally, so personally I use GetDNS.

Thanks John! That's exactly what I needed to know. By the way, 50E8 is running smoothly on my AC68U.


Occasional Visitor
I have one doubt, does it work in RT AC53 ? thanks a lot.


New Around Here
"Updated wireless drives for FRAGATTACK on AC68U¨
Does that mean the AC68U is the only model which has FRAGATTACK fixed? Will more models be fixed in another release?


New Around Here

Probably not. The FRAGATTACK fix needs updated wireless drivers from ASUS, and I believe the remaining routers supported by the fork are all considered EOL by ASUS.
Thanks for the explanation!

I tried updating my N66U to 50E8 LTS release, but I'm getting this error:
"Firmware upgrade unsuccessfully. It may result from incorrect image or error transmission. Please check the version of firmware and try again."
I checked the SHA256 and also confirmed it is the N66U version and not accidentally another one. Trying it over ethernet instead of WiFi gives the same error.
I'm still on 48E7, so I thought maybe I should upgrade to 49E4 first and then 50E8, but when I try to upgrade to 49E4 it's also that error.
