Chamberlin - MyQ tried everything RBK50

Frustrated...just spent a bit moving from my NIGHHAWK to the 'mesh' thing.

i have tried everything SHORT of RECONNECTING my old router and or extender

after spending time (so as you all dont waste your time)

I've tried it all, and some things I CANT NOT TRY..

unless im BLIND there isnt the abilty to DISABLE AM MODE (see below screen grab)

the CTS Values are all ready IDENTICAL

heres one I thought might work, (my idea) 

I enabled GUEST NETWORK and renamed to the PRIOR SSID NO SECURITY...(thinking as soon as i saw all the 2.4Ghz things show up) as I automatically saw my SMART LIGHTS and other ONLY 2.4Ghz things show up, thinking i was gonna save my time to reconnected them all...

I tried the WEB URL BROWSER idea from the garage door folks setup.myqdevice.com/start.html

that didnt work...

would it be easier to return my ORBI, go back to the old?

the only thing i havent seem any good instructions on is how to make the ORBI work with one of my old AC750 extenders?...

but again i really dont feel i should I did my homework and all my other only 2.4 Ghz devices have no issue...and i aint changing out my garage door :)

HELP!!! Please

Im a lifelong NETGEAR person and really dont want to undo this ORBI, it really is SO MUCH better then REPEATERS all over the house

thanks in advance
