I have a pair of these, one downstairs connected to the router and one in my sons room, ive been thinking now that i need another for my daughters rooms but not sure if i have to buy another "pair" or just one single adapter for her room, will a single unit connected to the router downstairs power two units upstairs ?
Also does the new unit have to be the same brand/model or can i mix and match the units ?
