RT-BE88U Works Fine for Clients, but Administrative Features Can't Access Internet

[Basspig]

I just installed an RT-BE88U router and amazingly, got my web server, streaming video server and NAS and all IoT devices working flawlessly.

The only issues seem to be with internal "bells & whistles" type features, such as the internet speed test and firmware updater. They cannot access the internet. Even though the internet status is "connected" and all client PCs have internet. It's baffling. What feature is not enabled that makes this not work? Or are these features not yet implemented in firmware?

Found solution to the speedtest not working: had to explicitly assign a DNS server to the router, not "get from ISP" or auto.

The Signature version field is there because you have enabled AiProtection.  But 2.066 may be old.  Please use the Check button to check for updates.

Prior to adding the DNS entry, I was unable to check version as well, but now it is working and up to date.
