I just updated my 3x RT-AX92U to this version (I guess they must be pretty similar to the AC86U if the build ID is the same?) and I can't get the AIMesh nodes to talk to the router anymore. I've spent the last hour resetting nodes, resetting the router, adding over and over. It either gets to 50% then speed-counts to 100% and shows the failure dialog, or goes all the way to 100% slowly then shows the failure dialog. I'm looking at downgrading to the one I was using before (hopefully 3.0.0.4.384.9177 but I stupidly didn't write it down...) because I just need to get the family back online, unless anybody has a good idea of something else I can do?
(I've done the reset using the red button on the back, using the web interface, and by holding the WPS button during boot until the power button flashes. Each time, I go back in with a wired connection and put it in Node mode, then try to add again. None have helped.)
ETA: would it help if I posted this as a new thread? I know my devices aren't as popular as the AC86U so hopefully that's why I haven't seen any AX92U-specific discussion yet...
