Unable to connect Chamberlain garage door opener via 5g internet

I have 2 MyQ openers on separate buildings. Both of them easily set up initially and worked perfectly. About a year ago they both went offline for a couple weeks.  I resolved it by doing a factory reset and restoring the SSID and password. The same thing happened again 2 weeks ago. Devices went offlline and I did the factory reset tonight. Once the SSID and password were restored both devices immediately were back online. I realize that this is a temporary fix, but thought it might be helpful to know that it wasn't always this way. I expect that the change happened during a software update and I'll be back offline when the next update is pushed out. Looks like I'll be adopting the solution recommended here. Thx for sharing.
