I tried both options and other wifi extenders that are connected to the blue curve modem.
All shown errors - something went wrong and mini google it s connected but not communicate to iPhone. Installation was incomplete
Yup. Me too. I just installed the Blue Curve modem yesterday and am having the same issue of non-connectivity. It took me a while, but the Help menu for the Google Home Hub I have says "it is NOT compatible with WPA2 security"..... My Hub and ALL of my mini's are Gen2 except 1 so I will try and connect that one tonight. See if it works. I have a Tech coming out next week to install the TV boxes so will ask if there might be a solution.
