What the RE450 does and who needs it
The RE450 is a dual-band wireless range extender that plugs directly into a wall socket. It supports 802.11ac and earlier Wi-Fi standards, delivering up to 1.75 Gbps combined throughput across 2.4 GHz and 5.0 GHz bands. Three adjustable external antennas help direct coverage toward weak spots. The unit includes a single gigabit Ethernet port for wired devices such as smart TVs or game consoles.
Practical limits of the AC1750 class
Maximum link rates reach 450 Mbps on 2.4 GHz and 1300 Mbps on 5.0 GHz, but real-world throughput is lower due to half-duplex relay traffic and interference. The 2.4 GHz radio operates below 20 dBm transmit power while the 5.0 GHz radio stays below 23 dBm. Receiving sensitivity drops to -61 dBm at the highest 5 GHz MCS9 rate, so distant clients will fall back to slower modulations. The single gigabit port caps wired backhaul at 1000 Mbps.
Installation steps and common pitfalls
Press the RE button to pair with the host router using WPS, or configure via web browser on Windows, Mac, Linux or legacy systems. The extender must be placed where the router signal is still strong enough to relay, typically within -70 dBm on 5 GHz. A frequent mistake is plugging the unit too far from the router, which yields a weak backhaul and slower extended coverage. The LED and power buttons help verify link status and reset the device if needed.

Questions about this item
Should I choose the 2.4 GHz or 5 GHz band for my devices?
The extender runs both bands simultaneously — 450 Mbps on 2.4 GHz for range and 1300 Mbps on 5 GHz for speed — so devices pick the best one automatically.
What does the AC1750 label mean for actual throughput in my home?
It combines 450 Mbps on 2.4 GHz and 1300 Mbps on 5 GHz for a total 1750 Mbps link rate; real-world throughput will be lower due to overhead and signal conditions.
Will the gigabit Ethernet port limit my wired connection speed?
The single 10/100/1000M port caps wired clients at 1000 Mbps, so a wired device can use the full 5 GHz wireless backhaul without bottleneck.
