I've currently got a Homeplug AV (Powerline AV200) network around my house that I've been using to stream films. However, I've recently ripped a few Blu-Rays at full bit rate and realised I've not quite got the bandwidth to stream them smoothly.
Doing a bit of testing, in real life the powerline network gets 23 MBit throughput between floors, and about 30 MBit between the media centre and server downstairs. Agonisingly short of what's needed. The Wireless-N network falls flat because the phone line comes in 'upstairs' so the signals are bounced up and down the stairs, and that can only manage 18 MBit.
NB for comparison I get about 80 MBit throughput on Wifi between rooms on the same floor. That's between a laptop using Wifi, and a desktop plugged in to the router directly via ethernet - so that Wifi speed may actually be limited by the 100 MBit ethernet link.
Does anyone have real life experience upgrading from AV200 to AV500 networks with fairly old wiring circuits? I've seen a few reviews suggesting the main gains are on the short runs / good signal quality rather than when pushing it.
Similarly has anyone seen significant gains going to 802.11ac? I'm very wary of Wifi speeds since I saw only about 10% speed boost going from 802.11g to 802.11n. I bought a whole set of matched equipment before settling on powerline stuff - that was returned to the store due to poor performance. I've since moved over to n anyway due to new broadband provider and new laptop and again, barely any speed boost from g.
