What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.5 for now.

Third-party reviews

What customers like about D-Link SE15

  • Wi-Fi 6 support brings faster speeds to newer phones and laptops.
  • The 5 GHz band is rated at 1201 Mbps.
  • Mesh and roaming let devices switch between units.
  • A dedicated app handles setup.
  • WPA3 security protects the connection.
  • The portable design makes it easy to move between rooms.

What customers don't like about D-Link SE15

  • There is only one LAN port, so just one wired device can connect.
  • It is for indoor use only and is not waterproof.
  • It works only from 0 to 40 °C, so cold or hot spaces are out.
  • There is no 6 GHz band, so it cannot use that extra spectrum.
  • Devices on the 2.4 GHz band are capped at 300 Mbps.

Verdict

Wi-Fi 6 at a budget price is the main draw of the D-Link SE15, a portable extender for a home with one weak corner. It runs on two bands, rated for 1201 Mbps on 5 GHz and 300 Mbps on 2.4 GHz. It works as a mesh node with a main router, and it has roaming, so phones and laptops can switch over on their own. Setup runs through the app, and a signal strength indicator helps you find a good spot. The trade-off is the single 1 Gbps LAN port, so only one wired device can plug in, and it is for indoor use only. It suits a family or a flat where one bedroom or office needs faster Wi-Fi, and the budget is tight.
