MyQ garage door opener will not connect through RE315
My Liftmaster Security Plus 2.0 MyQ garage door opener will not connect through my TP-Link RE315 range extender. I got new TP Link Archer AX73 router and RE315 range extender to improve signal in this detached shop/garage area. I have a Chamberlain MyQ opener in the attached garage of the house, and it connected easily through the main router and works fine.
The Liftmaster was installed new in late 2021. It was previously connected to an access point and operated fine but with weak signal. After upgrading to router and access point, I can remove the range extender, connect the opener through the main router Archer AX73 and it operates, but the signal is very weak and it periodically goes offline. When I the plug the range extender back in, the opener will not switch over and run through it with the better signal. It goes offline if I try to force it onto the range extender 2.4G band. The signal is very strong, and I am certain I am using correct SSID and password.
Router and range extender are normally set up as OneMesh with wifi SSID’s and passwords the same. I have tried the tricks on the internet support sites including shutting off wifi assist on my iphone XR, shutting off one mesh, separating 2.4G and 5G bands with different SSID’s, shutting off 5G bands, shutting off all SSID broadcasts except for the range extender 2.4G, shutting off smart connect. I have not tried any port authentication like #8883 mentioned in one troubleshooting article that may be related to the RE315, as I have not seen specific instructions/settings for my router.
I would sure appreciate any help. I like my TP-link system as designed and installed but need this opener to connect to the range extender, preferably in onemesh mode.
