Our recent upgrade to 300Mb/s fibre has highlighted a bottleneck in our powerline network. Thankfully the line comes into the house in the room my PC and my wife's Mac are situated in so we both get bang on 300Mb/s down and 50Mb/s up. Great. But our HTPC in the next door room and both my kids in their rooms upstairs are topping out at around 90Mb/s. We never noticed this on our old 17Mb service of course. Now, 90Mb/s is really still plenty fast enough for most things we need the internet for in those rooms, but my kids in particular are a bit miffed their downloads are a lot slower than mine. And I feel a bit put-out that we're not fully utilising what we're now paying for. I am using four TP Link AV1000 powerline units to share the connection from the room with our router to the lounge (HTPC) and the boys' bedrooms. I know the speed achievable is always a lot lower than the units' rated speed, but this seems a lot lower than the stated gigabit capacity. My hunch is that this speed is so much lower than the adapters' rating that it's most likely to be a limitation in our wiring? Is that a fair guess? We live in a late Victorian terrace, but the wiring was redone about 12 years ago I believe. I'm wondering if we might be better off with wireless connections now we have a BT wifi disc in the eldest's room, but last time I got them both wireless dongles to connect with they were terrible (slow, kept dropping out). Any recommendations for dongles or PCI-E wireless cards might also be useful.
