Tom Gilly,
Thank you for all the help. Update: after leaving all the power off to the TUI & Wifi over night, I plugged them both into the same power outlets and the wifi connected with all 3 lights (green power, purple tui, & blue wifi) lit. Everything is working as it should. This may sound funny, but I had this same problem over a year ago, and after leaving the TUI & Wifi powered off over night the next morning they both connected & worked fine. WHY????? I'm just thankful to have it back working as it should.
