first time on the forum and I am desperate for help. I have a Zyxel EX5401-B1 router and I cannot connect the TP-Link AC1750 to it. It was working well with an old Zyxel router but when I upgraded to the present one, I could not connect the extender. Has anyone experienced the same or heard of imcompatibility between these two products.

Any suggestions of which wifi extender will work with Zyxel-9017  EX5401-B1. Thank you
