Compact, value for money, but a compromise on performance,
Verified Purchase(What is this?)
This review is from: Zyxel 500Mbps Micro Slimline Powerline Adapter (Twin Pack) (Accessory)
Whilst typically half the price of its bigger brother the Zyxel PLA4205, which has a Gigabit Ethernet port, the PLA4201 is constrained by having only a Fast Ethernet port.
This means that whilst the PowerLine interface might have a theoretical throughput of 500Mbs the practical throughput is limited to under 100Mbs. Still sufficient for video streaming, but not the maximum achievable for file transfers.
That said its certainly compact and powers down when no active equipment is connected.
As manufacturers discontinue 200Mbs PowerLine models this 500/100 combination becomes the new entry point with 500/1000 being the premium choice.
