UniFi vs. eero & mesh Wi-Fi: what's best for a large home?

How consumer mesh Wi-Fi works

Mesh kits include two or three units you place around the house. One connects to your modem; the others connect to it, often wirelessly. They're affordable, look nice on a shelf, and are set up from a phone app in minutes.

The tradeoff: when units talk to each other over Wi-Fi, part of the wireless capacity is used just to relay data between them. The farther a device is from the main unit, the slower and less stable it gets. In big homes, homes with stucco or plaster walls, and anywhere with outdoor areas, that adds up to dead zones and dropouts.

How UniFi works

Ubiquiti UniFi is built like a business network, scaled for a home:

• Access points mount on ceilings in the right spots and connect with Cat6 cable, so every one runs at full speed.
• A PoE switch powers the access points and cameras over that same cable.
• A gateway manages the network, with separate networks for family, guests, and smart devices.
• One app shows every device, and lets us diagnose problems remotely. There are no subscription fees for the core networking.

Side-by-side

• Coverage: mesh is good in small and medium homes; UniFi is designed for any size, including yards, garages, and guest houses.
• Speed: mesh slows down with each wireless hop; UniFi gives full speed at every access point because each one is wired.
• Reliability: mesh is fine for everyday browsing; UniFi is built for heavy use, with many devices, 4K streaming, video calls, and cameras all at once.
• Setup: mesh is plug-and-play; UniFi needs cabling and configuration, which is why it's usually professionally installed.
• Cost: mesh costs less upfront; UniFi costs more upfront but scales without replacing everything.

Which one should you choose?

A mesh kit is probably fine if your home is under about 2,500 sq ft, mostly one level, and you mainly browse and stream on a few devices.

UniFi is worth it if you have any of these:

• A home over about 3,000 sq ft or on multiple levels
• Stucco, plaster, or brick walls that block Wi-Fi
• A backyard, pool area, garage, or guest house that needs coverage
• Sonos or whole-home audio, security cameras, or a smart home system
• People working from home who can't afford dropped video calls

What a UniFi install involves

A typical installation begins with the floor plan and a walkthrough to plan access point locations. Cat6 cable is then run through attics and walls, access points are mounted, and the network equipment is organized in a clean, labeled rack before everything is configured and tested. On one recent whole-home network, the same rack also powers a 6-zone Sonos system.

The bottom line

For a smaller home with modest needs, a quality mesh kit is a sensible, affordable choice. For larger homes, outdoor living spaces, and homes running audio, cameras, and smart devices, a wired system like UniFi is well worth the investment. Because it involves running cable and configuring the network, it is usually professionally installed. Learn more about UniFi Wi-Fi installation.

Frequently asked questions

Is UniFi better than eero?

For large homes, multi-level homes, and homes with lots of devices, UniFi's hardwired access points generally deliver stronger, more consistent coverage. For small homes, eero and other mesh kits are simpler and often enough.

Does UniFi have a monthly fee?

The core UniFi networking software has no monthly fee. You buy the equipment, and management is included.

How many UniFi access points do I need?

A typical 3,000 sq ft home needs 3 to 5 access points, depending on layout, construction, and outdoor areas.
