I'm creating this post to for those who cannot get their Chamberlain MyQ garage door opener to connect with a NetGear Orbi mesh router (mine: RBK753S/AX4200 purchased at Costco). I spent many days following all the threads and no solution worked. I was using a Samsung Galaxy Note 8 phone and following all the steps you find here: https://support.chamberlaingroup.com/s/article/How-to-connect-MyQ-Wi-Fi-garage-door-opener-to-WiFi-h... I always got the "cannot connect to wireless network". I then tried following posts that said "disconnect from AX" or "reduce power on 5GHz network" or "change port range to 2347". None of it worked
However, I finally determined that the I must have a problem with either Android (unlikely), 2.4GHz MyQ v. 5GHz phone radio, or something else. So I pulled out my old laptop (which was sure to be using only 2.4GHz) and connected it to the Chamberlain/MyQ wireless and did the set-up process using my laptop and Firefox web browser.
1. Turn on (reset) Chambnerlain/MyQ by hold black button garage door until all the lights go off (maybe 5-7 sec). Push yellow button 3 times. Now the black button flashes blue and you hear a beep. It's ready.
2. Connect my laptop to the MyQ wireless network (something like "MyQe8a" - can't recall). Connecting MyQ to the laptop
3. Type "setup.myqdevice.com" into a browser window. I used Firefox.
4. Ta-da! The image below. Then followed the steps to pick my Orbi wireless network name, enter my password, and then I was done. I didn't have to change any settings on Orbi or pick a specific 2.4 or 5GHz network (which you can't do anyway)
BOTTOM LINE: You just might need to find a compatible 2.4GHz device to help you connect the 2.4GHz Chamberlain/MyQ. Just try multiple devices. Maybe older = better.
