I had to purchase a new router because my old Spectrum wifi router stopped working.  MyQ app worked great with the old wirelss router. However, I have not be able to connect my garage door opener since installing the new routher.  I have no other problems connecting other equipment (Ring, thermostats, etc) to the 2.4 G wifi.  I have tried everything that Chamberlain has reccommended except the TCP 8883 port stuff.  Has anyone else found a fix to make it work?
