Orbi doesn't, no idea if Asus did, I didn't do anything to either routers thay just alowed access to 130.

Just out of interest, how often do you feel the need to access the 130?

At the moment not very much. But I had a line problem when I was using the Asus router that my ISP wanted a information every few hours over a number of days to kick Openreach into doing something. Than it would have been a pain having to cut the router off and risk it having to be rebooted to be happy when reconnected. With the Asus no problem access just like any other device and use the the Diagnostics. I don't there is likly to be a firmware update but that wouldn't be difficult its the multiple access for truble dignostices is thet weree ever needed again I would miss direct access.
