Hi, just set up a 3 pack Deco M9 plus system for a home network. Its working alongside a Virgin Media 3.0 Hub which has been put into modem mode. As I have changed the VM to modem mode I am now 2 Lan ports short of where the modem/main deco live. What would my best option be? Purchase a another single Deco M5 or M9 and place in near the VM modem/main deco or purchase a designated TP router and use the 3 decos as the extenders around the house? 

If the second option what router will work best with the M9's and would i need to completly reset the system or simply unplug the current main deco and replace it with a router and repostion this deco to somewhere else in the house?

Thanks

Andy
