TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

BroadbandNow's Kate Fann praised the 5 GHz speeds reached through the 160 MHz channel width and ranked it her Top Pick after testing across a three-story home. TechGearLab placed it among its heavy-duty Wi-Fi 6 picks for handling loads most plug-in extenders cannot.

TP-Link RE315 AC1200 Wi-Fi Range Extender

The AC1200 ceiling tops out at 1,200 Mbps, well below the Wi-Fi 6 picks. TechGearLab said its older Wi-Fi version limits speed, but Engadget's Valentina Palladino still measured good real-world performance for the price in basement dead zones.

TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

TP-Link rates it for up to 2,400 sq ft, and TechGearLab credited its adjustable antennas with reaching farther than typical plug-ins. It trails the longest-range Asus RP-AX58 but covers more than the budget tier.

TP-Link RE315 AC1200 Wi-Fi Range Extender

TP-Link rates it for roughly 1,500 sq ft, and TechGearLab framed it as the right tool for reaching one extra room rather than a whole floor. BroadbandNow noted the smaller coverage area versus pricier models.

TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

BroadbandNow called out the Tether app's customization options for advanced users, and the OneMesh and EasyMesh support lets it share one network name with a compatible router. TechGearLab noted the bulky body can be awkward at the outlet.

TP-Link RE315 AC1200 Wi-Fi Range Extender

TechGearLab credited its adjustable antennas and easy setup as making it the most accessible extender for casual users. Engadget called the Tether app setup quick and beginner-friendly.

TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

A Gigabit Ethernet port, EasyMesh and OneMesh roaming, and support for up to 64 devices put it ahead of cheaper plug-ins. It is dual-band rather than tri-band, so it lacks a dedicated backhaul like the pricier Wi-Fi 7 models here.

TP-Link RE315 AC1200 Wi-Fi Range Extender

OneMesh support and a 10/100 Ethernet port cover the basics, but the port is not Gigabit and TechGearLab warned it cannot juggle many connected devices at once. There is no Wi-Fi 6 and no dual Gigabit.

TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

TP-Link RE315 AC1200 Wi-Fi Range Extender

It is TP-Link's most-recommended budget extender, appearing as a budget pick in Engadget, BroadbandNow, and as TechGearLab's outright Editors' Choice. The Tether app and firmware match the rest of the TP-Link line.

Strengths & Weaknesses

TP-Link RE715X AX3000 Wi-Fi 6 Range Extender

+ Strengths
  • BroadbandNow's Kate Fann named it her Top Pick, praising fast 5 GHz speeds through the 160 MHz channel
  • TechGearLab rated it a heavy-duty option that handles more connected devices than most plug-in extenders
  • Works with EasyMesh and OneMesh, so it shares one network name with a compatible router instead of creating a second
Weaknesses
  • BroadbandNow found it pricey next to similarly capable Wi-Fi 6 rivals
  • TechGearLab flagged the bulky body, which can crowd a second outlet
  • Dual-band design has no dedicated backhaul, so it gives up some throughput to the Wi-Fi 7 models here
Key flaw: BroadbandNow found it pricey next to similarly capable Wi-Fi 6 rivals, and TechGearLab flagged the bulky body that can crowd a second outlet.

TP-Link RE315 AC1200 Wi-Fi Range Extender

+ Strengths
  • TechGearLab named it Editors' Choice, calling it the most accessible extender for reaching one extra room
  • Lands in the budget slot for Engadget and BroadbandNow too, usually selling around $30
  • Adjustable antennas and a quick Tether app setup make it the easiest pick for first-time buyers
Weaknesses
  • TechGearLab said its older Wi-Fi 5 standard caps speed below every Wi-Fi 6 model here
  • BroadbandNow flagged the smaller coverage area and higher latency than pricier extenders
  • The Ethernet port is 10/100 rather than Gigabit, so a wired device is held back
Key flaw: Wi-Fi 5 caps its speed below every Wi-Fi 6 model here, and the 10/100 Ethernet port holds back any wired device.

The Verdict

Our Bottom Line

The TP-Link RE715X is the extender the most reviewers actually trust to cover a whole house. BroadbandNow's Kate Fann made it her Top Pick after running speed tests across a three-story home, praising the fast 5 GHz performance it pulls through the 160 MHz channel. TechGearLab put it among its heavy-duty Wi-Fi 6 picks, the rare plug-in that handles more connected devices than its size suggests. Its retail listing also carries a PCMag Editor's Choice badge.
