I have 4 of the old AV500 Powerline Adapters, with 100Mb ports across my house. I've recently upgraded my broadband to 500Mb. What I want to know is if I bought 1 single AV1000 adapter with a Gigabit port and used it as the 'In' connected to my Modem, would it pass those 500Mb speeds around the house, before each old adapter called for just 100Mb due to its older port? But realistically, drop off aside, could I get those 4 AV500 series adapters running at a theoretical 100Mb?

If so is there any downside to doing this? 100Mb wired in each location would probably be enough for me.

 

Would the drop off due to electrical noise be less of a factor also? Say two AV500s were in active use at the same time, could I get close to 100Mb speed on both even if I currently only get 50Mb due to noise/distance?

 

Thanks in advance anyone who can help. Thought I'd try the community first!

Hi,

 

Here is my take on this subject.

 

The AV500/AV600 Powerline adapters use the "HomePlug AV" standard. The faster Powerline adapters (AV1000 and up) use the "HomePlug AV2" standard to achieve higher speeds, but are backwards compatible with "HomePlug AV". When communicating with an older AV500 Powerline adapter the AV1000 Powerline adapter would switch to the slower "HomePlug AV" standard, hence there would be no improvement in that regard.

 

In practical use cases, Powerline adapters following the older "HomePlug AV" standard will rarely be able to achieve more than 95 Mbps actual data throughput, which would be the point when a 100 Mbps Ethernet port would become the bottleneck.

  @woozle Thanks. I can confirm that it runs on one standard or the other. It will either connect to its fellow AV2 standard adapter, or the older AV1 adapters, but never both. Massively disappointing and not remotely obvious from ALL the literature and product descriptions. I'd put up with the newer one connecting at Max 100Mbps speeds but the truth is it won't even pair at all if you've already paired with AV1 adapters!
