New Router Advice Needed

My ISP is WIFI based and requires a login for access to the Internet. I currently have a GL.iNet GL-AR750S-Ext. I am having signal issues and looking to upgrade to a different router that will allow me to use and external antenna and still be able to login to my ISP using WIFI. I am looking for a recommendation on a router I can purchase.

Do you mean EAP (802.11x) wifi network that requires username and password?

Pls use these AR750S, AR750, B1300, AX1800

Do not choose MT1300, SFT1200, MT300N-V2
