Having Issue to be Connected to the Original Wifi with the PW given

[HappyValleyBing]

Been in this house for 2 years and haven't tried to connect to Ruckus. Switched to a different internet provider and I was wondering about giving it a try.

Connected the yellow cable to the Ruckus hub/splitter in the cable box. Everything shows green light. And the 2 AP blue cables are also plugged in as well. 

When I tried to connect to Wifi, on any of my devices, keeps on showing 'connecting', at the end they all failed to connect.
