How do I connect Chamberlain Internet Gateway to my Router T3200M?

[mnzmantra1]

I recently purchased a Chamberlain internet gateway to operate my garage door opener remotely. I need to connect this Chamberlain internet gateway to my router. I tried multiple times but the gateway won't connect. Can someone help me with how I can connect it to my router?

I am using this video as a guide to connect https://youtu.be/37fiEGy045Y?t=29 but the green light would not turn solid. What should I do?

Please guide.

What is the distance between the router and the gateway?

Have you tried placing the gateway near the router and then doing the configuration?

I had no problems connecting the gateway to my t3200, but I have have separate SSID for 2.4 and 5Ghz.
