Dual-band AC1200 range extender

The TP-Link RE305 is a dual-band wireless range extender that repeats an existing Wi-Fi network on both 2.4 GHz and 5 GHz bands. It delivers up to 300 Mbps on 2.4 GHz and up to 867 Mbps on 5 GHz for a combined AC1200 rating. The device suits home or office users who need to fill coverage gaps without running new cables.

Check router compatibility and placement

Before ordering, confirm your router supports IEEE 802.11ac or 802.11n on 2.4 GHz and 5 GHz. The extender connects wirelessly, so you must place it where the router signal is still strong enough to relay. A 10/100M Ethernet port allows wired clients or access-point mode if a cable run is available. Setup uses a WPS button or the TP-Link Tether app on Android or iOS.

Low power draw and silent operation

Maximum power consumption is 7.3 W, so the unit adds minimal load to a mains socket. Two external antennas handle transmit and receive duties without any moving parts, meaning the extender runs silently. Transmit power stays below 17 dBm on each band, keeping heat output low during continuous operation.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The RE305 unit ships with two external antennas and a 10/100M Ethernet port. No Ethernet cable is included, so purchase one if you plan to use access-point mode.

The product is sold as AC1200 — how do the 300 Mbps and 867 Mbps bands combine?

AC1200 is the sum of the two radios: 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. You connect each device to one band, not both simultaneously.

What does the 867 Mbps figure mean once the extender is plugged in at home?

867 Mbps is the maximum 5 GHz PHY rate under ideal conditions. Real-world throughput will be lower due to walls, interference and the 10/100M Ethernet backhaul limit.
