Powerline Ethernet adapters run Ethernet signals over electrical wiring. This can be particularly useful in a home that has impediments to wireless signals getting through.

If you want Powerline adaptors with wifi and spare Ethernet sockets, the BT Wi-Fi Home Hotspot 500 Kit is a good option. Macworld is your best source for all things Apple.

As with other PowerLine Ethernet adapters we've checked out (such as those from Netgear and Zyxel), the Linksys PowerLine Ethernet network can support up to 16 devices.
