1 / 7TP-Link RE315 AC1200 Dual-Band Wi-Fi Extender
The TP-Link RE315 AC1200 Wi-Fi extender is a dual-band repeater intended to improve coverage where a router’s signal is weak. Its stated 1.2 Gbps is combined band bandwidth, not a promise of faster internet, TP-Link says extender speeds may be 50% or less of current speeds.
At a glance
- Adaptive Path Selection is described as choosing the strongest signal as you move around the home.
- The Tether app supports setup and management on Android and iOS, an intelligent signal indicator helps with placement.
- EasyMesh-compatible routers can provide one unified Wi-Fi network and roaming, other routers use a separate extender network name.
- Access Point Mode and an Ethernet port provide additional connection options.

What to know before buying
- Coverage and device-capacity figures are listing claims, actual performance varies with distance, obstacles and conditions. EasyMesh unified networking requires a compatible router, and the extender is not compatible with Deco mesh systems, with a non-EasyMesh router it creates a separate SSID.
Who is it for?
A good fit for
- Homes with Wi-Fi dead zones where improved signal reach matters more than maintaining full router speeds.
- Users who want an Ethernet connection for a nearby wired device or have an EasyMesh-compatible router.
Less suited to
- Buyers seeking higher internet speeds rather than wider Wi-Fi coverage.
- Owners of Deco mesh systems or shoppers who require a unified network with a non-EasyMesh router.

The only feedback evidence supplied is an aggregate rating of 4.2 out of 5 stars, with no rating count or written customer comments. That figure alone does not identify specific strengths or problems, buyers should weigh it against the stated trade-off that coverage extension can come with substantially lower speeds.
Frequently asked questions
Does the RE315 increase internet speed?
No. The listing describes it as a coverage extender, not a speed booster, and says actual speeds may be 50% or less of current speeds.
Will it create one Wi-Fi network with my router?
The listing says a compatible EasyMesh router can provide one unified network and roaming. With a non-EasyMesh router, the extender creates a separate network name, Deco mesh systems are not compatible.
Can I connect a wired device?
Yes. The listing specifies a fast Ethernet port for connecting a device.
What coverage does TP-Link claim?
The listing claims coverage up to 1500 Sq. Ft and support for up to 32 devices, while noting that results vary with distance, obstacles and conditions.
