Linksys PLWK400 review

£119.99 inc VAT

Manufacturer: Linksys

Our Rating: We rate this 3 out of 5

The Linksys PLWK400 works perfectly from a technical point of view and its Wi-Fi option is very useful. Configuring the PLWK400 isn't as simple as it ought to be though. Read our full review of the Linksys PLWK400 to find out more.

The PLWK400 kit from Linksys includes Wi-Fi so you can extend an existing Wi-Fi network into areas that your router might not normally be able to reach. However, there are some aspects of its design that are rather unwieldy. See all Wi-Fi and networking reviews.

Most HomePlug devices point downwards from the mains power socket so that the Ethernet cables trail straight down onto the floor and can be tucked out of sight. Visit Devolo dLAN 200 AV Wireless N review.

Linksys has placed the single Ethernet port right on the top of its adaptors, which means that the Ethernet cables protrude upwards for several inches in a rather unsightly fashion. However, this could be an advantage if your mains sockets are close to the floor. See also D-Link W307AV PowerLine Homeplug AV Wireless N Starter Kit review.

Of course, design doesn’t affect performance (or shouldn't anyhow), and the PLWK400 was able to back up our 1GB test file at 60.2Mbps. That’s not the best we've seen by any means, but it’s respectable for a HomePlug AV kit.

There’s a ‘Simple Connect’ button that allows you to automatically create a secure link between the two adaptors, and to quickly add further adaptors as well. There’s a similar security button for the built-in 802.11n Wi-Fi too, but as we've said in other reviews, the WPS system can easily be compromised so don't choose a kit because it has push-button security.

The manual and the configuration software provided with the kit aren’t very clear about how to set up Wi-Fi, so less technical people could easily get lost here. The manual also fails to explain other options, such as the QoS (quality of service) feature that allows you to prioritise certain types of network traffic.

From a technical point of view the PLWK400 kit works perfectly well, and its Wi-Fi option will be useful for many people. However, the unhelpful manual and configuration software mean that you’ll need a fair bit of network know-how in order to get the most out of it.

    Linksys PLK300

    The lack of a connection-quality indicator and a wall-mount option hamper the Linksys PLK300 - an otherwise very capable powerline kit.

    Linksys Powerline HomePlug AV2 Kit - small, decent Powerline adapters

    The Linksys Powerline HomePlug AV2 Kit is simple to set up, offers decent speeds, and is unobtrusive but is over priced for a non-WiFi solution.

    Linksys WRT300N

    The Linksys WRT300N router is a Mimo device with a difference – instead of three identical antennae, it has two plus a large paddle-shaped antenna between them.

    The Solwise 200Mbps HomePlug AV Ethernet kit is a cheap way to get started with Powerline networking. The kit is pretty basic, but it works perfectly fine. Read our Solwise 200Mbps HomePlug AV Ethernet kit review to find out more.
