Hi

im hoping somebody can help, ive got 3 deco m5's to help with signal around an old house with very think brick walls.

my broadband is provided by Plusnet, their provided modem / router is terrible. To try and get the system up and running I've taken an old router / modem (linksys X6200) put it into bridge mode and disabled the SSID. All good that works but only lan port 1 on the linksys will work which is where I plug the first deco unit into. 
 

I have several items that need a wired connection so I'm wondering if I can use a network switch somewhere in the configuration to get me extra wired availability? 
 

Or is there a way I can get the LAN ports on the linksys to work or to connect another router (no modem) so I can use the lan ports on that?

cheers in advance.
