Overview
Covering a home with dual-band wireless is the job of this router, which ships with a power adapter, an Ethernet cable and a quick install guide. It supports EasyMesh per the title, so a compatible extender can widen the network later.
The reason to buy is a modern Wi-Fi standard with gigabit wired ports and Alexa support in a compact box. The limit is that coverage is described only as wide, with no area given. Which mesh extenders work with it is also not spelled out.
Who it's for
Apartments and mid-size homes with phones, a console and a few laptops are the typical setting. Big houses with thick walls, and users with multi-gig internet plans, should look for something with more reach and faster ports.
Pros and cons
- Newer Wi-Fi standard
- Gigabit Ethernet ports
- Alexa and app control
- Cable and adapter in the box
- Coverage range not quantified
- Fixed antennas cannot be swapped
- Multi-gig ports absent
Performance notes
Beamforming steers the signal toward each device, which helps distant rooms, while the dual bands split traffic between slower and faster radios. Wired devices get gigabit links through the Ethernet ports. Actual speed follows your internet plan, the distance to the router and the walls in between.
