Upgraded directly, no issue so far. Snappier UI than 3.0.0.6.102.33421.

Anyone know why this version is listed on the Asus support website, but a search for new firmware in the app and web GUI says no new firmware available?

Is it just a latency issue?

Situation normal, it often takes a few days for all of the company piece parts to get on the same page.

OK thanks. Seems like the query would check a config DB that would get updated in real time when a new version is uploaded.

But I guess I can do a manual update if I can’t wait.

I recently installed beta Version:9.0.0.6.102_37342 which fixed guest network pro’s GUI missing dhcp reservation options. I’m foggy on it, but I think an update took it away over a year ago on mine. Back then I just jumped to Merlin, but I started using mesh nodes this month and wanted to see if stock firmware handled my devices better. I also really need reservations to tie down some flaky IOT devices with dns/firewall, and saw the feature not there to set. I reset to factory, rescue loaded, and nothing restored the GUI to manage them till the beta did. Again foggy on the details, maybe I confused if it should have ever been there.

Does anyone have the beta I’m on downloaded in case I want to try 3.0.0.6.102_37421 ? I got it automatically from the GUI and don’t want to screw up if it’s not offered to me later. Then again, maybe not touching things because everything seems to be working well now.
