Tp-link AV1200 Powerline Wi-fi Kit WPA8730

£115 from www.snipca.com/23766 Tested: Issue 495

Homeplug adapters use your mains wiring to extend your network where Wi-fi won’t reach. This kit provides Wi-fi at the far end too, so phones and tablets can connect as well as PCS and other Ethernet-equipped devices.

ALTERNATIVE: D-link Powerline AV2 1000HD Gigabit Starter Kit Fast (speeds of up to 1000Mbps), much cheaper and very easy to set up, but the lack of a passthrough socket is frustrating. £22 from www.snipca.com/21691
