TM6900 and Spiderbox

[pricey]

I am running a Spiderbox 9000 in one room of my house. Connection to the internet is via a pair of homeplugs. I also have a TM6900 in another room which I managed to revive from info in this forum. I have been disconnecting a homeplug from the Spiderbox and connecting to the TM when required. But how can I run both together? Do I need another set of homeplugs or just one? Or is there an alternative way? Thanks in advance.:confused:

if you need 2 locations to work then use 3 homeplugs of a similar type, one in each room and one at the router
