Connecting other satellites to an RBR20

Hi all,

I have had an RBR20 for a few years, hasn’t missed a beat, but now I’ve moved into a bigger house I need another satellite.

Things have moved on since I bought this, and I’ve looked to see what satellites will connect to this router, but it’s a bit of a minefield with a lot of options.

Could someone please let me know which satellite I can use? It’s to go near the back door, possibly even outside. The Internet is a bit patchy in the garden.

Cheers all,
