Extend 2.4 GHz coverage up to 800 sq ft

This single-band N300 extender repeats a 2.4 GHz signal at up to 300 Mbps using two external antennas. It supports range-extender and access-point modes and includes one 10/100 Mbps Ethernet port for wired devices. The unit plugs directly into a wall outlet and draws about 3 W.

Plug into any wall outlet near the existing router

No extra cabling or power adapter is required beyond the built-in prongs. The Ethernet port lets a smart TV, game console or desktop connect by wire while the extender handles the wireless hop back to the main router. Setup uses the RE button or a web interface on Windows, Mac, Linux or older systems.

Maintains link under continuous streaming loads

The receiver sensitivity figures show consistent thresholds down to 270 Mbps across a range of data rates, indicating stable demodulation during sustained traffic. Operating temperature is rated 0 °C to 40 °C, so the device stays within spec during prolonged use in typical indoor conditions.
