Single-band 2.4 GHz range extender

The RE105 plugs directly into a wall outlet and uses two external antennas to repeat an existing 2.4 GHz network at up to 300 Mbps. It supports IEEE 802.11b/g/n standards and WPA/WPA2 encryption for broad router compatibility. A Fast Ethernet port lets wired devices join the extended network. Setup is managed through the TP-Link Tether app on Android or iOS.

Best for basic coverage gaps

Homes that only need to push a 2.4 GHz signal into one or two extra rooms will find the RE105 simple and affordable. Buyers who need 5 GHz band support, dual-band roaming, or gigabit wired speeds should look at a different model. The single radio cannot serve 5 GHz clients or mesh with dual-band systems.

300 Mbps 2.4 GHz throughput ceiling

The extender’s single 2.4 GHz radio tops out at 300 Mbps under the 802.11n standard, so real-world speeds will be lower and shared between wireless clients and the uplink to the main router. This figure decides whether the RE105 can handle the intended streaming or browsing load.

Questions about this item

What must my existing router support for the RE105 to extend its signal?

The RE105 works with any router, gateway or access point that operates on the 2.4 GHz band using IEEE 802.11b/g/n standards.

Can I connect a legacy device that only supports 802.11b speeds to the extended network?

Yes, the RE105 maintains backward compatibility with 802.11b clients at up to 11 Mbps dynamic rate.

How do I confirm the extender is placed where the 2.4 GHz signal is strong enough?

Use the TP-Link Tether app on Android or iOS; its intelligent signal indicator shows the optimal location for the best connection.
