What to know before buying

Listing details to confirm

The stated 300 Megabits Per Second data transfer rate and the feature claim of up to 300 Mbps wireless refer to different listing details. The listing also describes up to 300 metres over the electrical circuit, which is a claimed range rather than a guaranteed result. Actual speeds and coverage depend on the network and electrical installation.

Frequently asked questions

Can the TL-WPA4220 connect to a router on its own?

It is listed as an add-on adapter, so it needs an existing compatible powerline adapter connected to the router.

How many wired devices can connect directly to it?

The listing specifies two Ethernet ports for wired devices.

What wireless speed does the listing claim?

A feature claim states up to 300 Mbps for wireless connections. This is a listing claim, not a guaranteed real-world speed.

Does it include an Ethernet cable?

The box-contents field lists a powerline adapter. Manufacturer text elsewhere says one Ethernet cable is included, so confirm the contents of the selected listing before purchase.
