Mine is not the best test for AiMesh since my one node is in the garage (low use). That said, I've experienced some 2.4 disconnects out in the yard on that side of the AiMesh. And this weekend while working in the garage, my 2.4 client saw a variable 2.4 signal, and even when it looked good and connected, it didn't work well. Then my 2.4 backhaul dropped. And at one point the node dropped offline... more than once.
I completely rebuilt the AiMesh from scratch after first refreshing just the node. Same issues persisted. I began to think my second 2018 China 86U was failing and did some shopping around before pausing to rethink the problem. The earlier yard disconnects on the garage node suggested a possible firmware issue I did not suffer enough earlier.
I reviewed previous firmware discussions and found
similar WiFi issues reported for build 81918... I started looking there and stopped looking there.
So, I have downgraded from 81992 to 81858 and appear to have stable WiFi again on my node... I can feel it!
So, heads up!
Footnote: After downgrading the firmware, the webUI login could not be satisfied and invoked the Captcha and never could be satisfied no matter the login credentials used. So, you must reset at that point and then you can proceed. I proceeded through the Quick Setup to use the webUI reset with Initialize to reset again before configuring the router... the belt and suspenders approach. (Explained
here.)
