Can't Connect my Chamberlain MyQ Wifi garage door to my Tmobile Home Internet

I just got mine set up last night.

I had to hook it up to my DECO WiFI Mesh System. 

It wouldnt connect at first but this is what I did: 

I had to set up a guest network under the Deco that wasnt password protected. 

Then I connected the Garage Opener to the guest network with the MyQ App

(Make sure your phone is connected to the guest network while setting up or the doors wont work)

Next you will get on your regular wifi connections on youir phone and change the wifi settings back to original on your MyQ app. (the opener will allow a password protected wifi channel now).
