Warning!! Whomever uses AX88U routers in iMesh configuration, DO NOT update to the latest firmware Version 3.0.0.4.386.48631, It will completely destroy your Nod(s) connection(s).

Last night after updating both, my router AX88U and Nods (same routers) and no matter what, my Nods would not connect, in fact , upon trying to optimizing them I even brought one from my upper floor next to the router (2 feet away) It would disappear, I had to physically use wired connection ( I don't use ethernet backhaul mode) never needed, but that's the only way I could downgrade my Nods to previous firmware which again, have been working flawlessly.

This is terrible firmware update that should have never been released
