As mentioned above easier to use all from same brand. The so wise piggy6 is fantastic bit of kit, got my router, tv and HTPC all wired into it, it’s a round 6 socket surge protector with a 3 port switch built into it, just plug it in and instant switch plus power for all my av kit.
I run mine with devolo 200mbps av+ plugs to my pc upstairs and printer but in the old house had them connecting up to my 360 in the bedroom so I could use it as media centre extender since tv signal was so poor and have sat tuners in the HTPC running MCE.
That said getting the two brands to talk to each other was a bit of a pain since each manufacturer sets the network password to something different but after a lot of faffing and a couple of mails/calls to so wise got it sorted, their support nods were excellent.
