Netear router and netgear extender

I can not get anything to connect to my Starlink.  If I try my Netgear router and put Starlink on bridge mode...nothing. So, I thougt I would try an Netgear extender and login to extender network and all I get is "no internet"  I have tried the nighthawk app.  Do I need to attach the extender to my laptop?  Very frustrated.
