How to connect Outdoor 5G router to a network switch

[Woodcity123]

Have a new 5G outdoor router. Eero nodes incredible - 300mpbs :-)) Very close to the cellsite so have great coverage anyway. Want to get rid of BT altogether with 5G router - tried connecting to network switch to connect data ports throughout the house but no go?
Any idea what type of equipment I should be using? How to set up?

Hello there. 

Welcome to the Three Community. 

Can you detail the set up configuration you're using, and what's happening when you try?
