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 SE30

  • The 5 GHz band is rated at 2402 Mbps.
  • OFDMA lets several devices share the link at once.
  • Mesh and roaming keep devices on the nearest unit.
  • Automatic firmware updates keep it current without any effort.
  • WPA3 security protects the connection.
  • The portable design makes it easy to move between rooms.

What customers don't like about D-Link SE30

  • It is for indoor use only and is not waterproof.
  • There is only one LAN port for a wired device.
  • It works only from 0 to 40 °C.
  • There is no 6 GHz band, so it cannot use that spectrum.

Verdict

A fast 5 GHz band is the main reason to look at the D-Link SE30, a Wi-Fi 6 extender for a home with thick walls. Its ratings are 2402 Mbps on 5 GHz and 574 Mbps on 2.4 GHz. OFDMA lets several devices share the link at once, which helps busy homes with many phones and laptops. It also works as a mesh node and handles roaming, so devices move between units on their own. Firmware updates install on their own, and the app handles setup, so there is little to manage. The trade-off is that it stays indoors, and it has just one LAN port for a wired device. It suits a family home where the upstairs signal is weak and the router sits far away.
