Can't connect my device

Thanks, ya'll! I was able to connect my 2 iAdapt Air units to the router finally.

I unplugged the 2 satelight units and was able to connect the small unit but the medium still wouldn't connect. So using the tips you gave me I was able to figure out how to disable 5G. Still the medium wouldn't connect. 

So I turned off wifi on my phone, then back on to establish a fresh connection to the router (since I'd changed settings), and reset the iAdapt by turning the unit off then holding down the Smart button until the green and red lights flashed. Then I was able to connect the unit to the router.

I'm still not able to resend the confirmation email from the app though. Keep getting a notification that I need to check my network connect and try again. Any ideas on that one??

Thank you!!
