Seems like a decent price for a well reviewed AC1750 dual-band range extender with gigabit port. Also available from Maplin for the same price I believe.Description:
Tired of Wi-Fi 'dead zones'? The TP-Link AC1750 Wi-Fi Range Extender connects to your router wirelessly, strengthening and expanding its signal into areas it can't reach on its own. The device also reduces signal interference to ensure reliable Wi-Fi coverage throughout your home or office.
The RE450 comes with next generation 802.11ac Wi-Fi technology; 3x faster than the standard 802.11n speeds. The RE450 delivers fast dual band speeds of up to 1750 Mbps, providing reliable connections for bandwidth-intensive tasks like HD/4K streaming, lag free gaming, and large file downloads. A Gigabit Ethernet port turns the extender into a wireless bridge, letting you connect a wired device to your Wi-Fi network.
The extender RE450 works with any standard wireless router, and instantly connects by pressing the extender's RE button followed by the router's WPS button (if available). Once connected with an existing router, you can use the built in indicators to find the perfect place to put the RE450, with no further configuration required.
