Extend an existing Wi-Fi network

The TP-Link RE315 AC1200 range extender is designed to carry an existing router's wireless network into areas where reception is weaker. It is a practical option for planning coverage in a bedroom, office or another part of the property without replacing the main router solely to reach that location.

Dual-band wireless and a wired connection

The RE315 specification lists wireless link rates of up to 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. AC1200 describes the wireless class, not a guaranteed internet speed to one device. A 10/100 Mbps Ethernet port provides a wired-device connection; it is not a Gigabit port.

• Model: TP-Link RE315.
• Wireless class: Dual-band AC1200, with 2.4 GHz and 5 GHz bands.
• Ethernet: One 10/100 Mbps RJ45 port.
• Setup/control options include TP-Link Tether, the web interface and WPS where the router supports it.
• A signal indicator helps choose a suitable installation position.

Placement and mesh compatibility

Place the extender where it still receives a useful signal from the router, rather than at the far end of an existing dead zone. Walls, interference, connected clients and the broadband connection affect the results. Neither a fixed floor-area coverage nor lag-free gaming is guaranteed.

TP-Link documents mesh features for supported RE315 hardware and firmware. Whether your unit uses EasyMesh or OneMesh, and whether it can join your router's mesh network, must be checked against the exact versions. Ordinary range extension does not mean universal compatibility with every mesh system.

Before ordering

Share your router model and the area you want to reach. Confirm the supplied hardware revision, plug type and firmware compatibility. The team can help identify a useful position and setup approach based on the building and your devices, rather than assuming one coverage figure fits every property.
