We get this question almost every week from homeowners in Lehi, Draper, Park City, and the east bench of Salt Lake: “I have a 4,000 square foot house and my three-pack of Eeros just isn’t cutting it. Should I buy more Eeros, or do I need to go to UniFi?”
The short answer is that Eero and UniFi solve overlapping problems with completely different philosophies. At about 4,000 square feet — which is roughly the median new-build size in Lehi, Saratoga Springs, and Herriman — the gap between them becomes very obvious. Here’s the real comparison, without the forum noise.
What Eero is actually good at
Eero, especially the Pro 6E and the newer Max 7, is genuinely excellent at the job it was designed for: giving non-technical households usable Wi-Fi in a reasonable amount of time with almost zero setup. Plug a node in next to the modem, plug two more nodes in around the house, scan a QR code in the app, done. For a 1,800–2,500 sq ft rambler with drywall-on-stud construction and maybe 15 connected devices, that installation is going to make everyone happy.
Amazon also ships updates to Eero frequently. The app is polished, the failover is seamless, and band steering works pretty well. None of that is marketing fluff — it’s real.
Eero’s problems start showing up when three assumptions break: that the house is small, that the walls are drywall, and that the backhaul can be wireless. A 4,000 sq ft Utah home usually violates all three.
Why 4,000 sq ft is the cliff
Utah homes at this size almost always have:
- Two or three finished floors— a main level, an upstairs, and a finished basement. Each poured-concrete floor slab kills 15 to 25 dB of 5 GHz signal.
- A stone or brick fireplace wall— and the fireplace is usually in the middle of the great room, right where you’d want to put a mesh node.
- Long, skinny floor plans common to Lehi and Saratoga Springs builds, where the master suite is 70 feet from the family room. Signal falls off with the square of distance; 70 feet through two interior walls is a serious attenuation problem.
- Forty to eighty connected devices— phones, laptops, TVs, cameras, thermostats, garage openers, robot vacuums, a few smart bulbs in every room, and an Apple Watch per occupant. This is the real device count in a modern family home.
The Eero wireless backhaul gets taxed at every one of these. We explained the half-duplex math behind mesh backhaul in detail separately — the short version is each wireless hop roughly halves effective throughput, and the penalty compounds in heavy-construction homes. You’ll see 900 Mbps next to the main node and 90 Mbps in the basement bedroom, even on a gig fiber line.
What UniFi actually is (and isn’t)
UniFi is Ubiquiti’s prosumer / light-commercial networking line. At a 4,000 sq ft house, a typical UniFi install looks like this:
- A Cloud Gateway (UCG Ultra, Dream Router, or UDM Pro) acting as router, firewall, and controller.
- A PoE switch — usually a 16-port or 24-port UniFi Pro Max — to power access points and cameras over a single Ethernet cable.
- Two to four ceiling-mounted Wi-Fi access points (U6 Pro, U7 Pro, or U7 Pro Max depending on budget), each wired back to the switch on Cat6.
It’s not a kit you take out of a box and plug in around the house. It’s a designed system where each AP gets a wired uplink, the router centrally manages channel assignments and roaming, and you can segment IoT, guest, cameras, and the main network into separate VLANs.
UniFi isn’t magically faster radios — a U7 Pro and an Eero Max 7 both support Wi-Fi 7 on similar silicon. The difference is what’s behind the radios. A wired AP has a 2.5 Gbps backhaul link with zero contention and every radio free for clients. A mesh node is sharing one of its own radios with backhaul traffic, even on tri-band — the dedicated backhaul radio is still wireless and still subject to the same walls.
The 4,000 sq ft head-to-head
Eero Pro 6E three-pack
- Hardware: ~$500
- Install: 30 minutes, self-install
- Far-room throughput (basement bedroom, gig fiber line): typically 120–300 Mbps, dropping when kids stream on other floors
- Latency: 8–25 ms internal
- Roaming between nodes: sticky devices cling to distant nodes, require toggling Wi-Fi on and off
- Network segmentation: a single guest network toggle, no proper VLANs
- Total 3-year cost of ownership: ~$500 (hardware only if you skip Eero Plus)
UniFi install — Cloud Gateway Ultra + 24-port PoE switch + 3 U7 Pro APs
- Hardware: ~$1,100
- Install: 1–2 days with Cat6 runs in attic or wall chase; clean patch panel in the rack
- Far-room throughput: 600– 1,200 Mbps on a gig line; scales with multi-gig fiber
- Latency: 1–3 ms internal
- Roaming: 802.11r fast roaming, phones hand off between APs cleanly
- Network segmentation: full VLAN support — main, guest, IoT, cameras, office
- Total 3-year cost of ownership: ~$1,100 plus labor; zero monthly fees
You’re paying roughly double in hardware plus labor for install, and the result is 3–5x the usable throughput in the hard-to-reach rooms, dramatically lower latency, and a network that can actually accommodate the device count a modern family generates.
When Eero is still the right call
Not every house needs UniFi. Eero (or any decent mesh kit — Orbi, Deco, Nest Wifi) is the right answer when:
- The house is under about 2,500–2,800 sq ft and you don’t have heavy concrete or stone construction.
- You can’t run new cable (rental, HOA, finished retrofit with no attic access).
- Device count is under 30 and you don’t need separate networks for IoT or cameras.
- You need something up and running today and can’t wait a week for a proper install.
For a townhome in Midvale or a rambler in Taylorsville, a two-pack of Eeros with wired backhaul between them might be genuinely the best answer. A 4,000 sq ft home in Alpine with a walkout basement and a detached shop is a different problem.
The hybrid option people miss
If the idea of abandoning Eero entirely feels like overkill, there’s a middle path that works shockingly well: keep Eero as the router, but wire the nodes.
Every Eero has a second Ethernet port. If you run Cat6 from the main node to the other nodes’ locations and enable wired backhaul in the app, each node now has a full-speed dedicated uplink. Performance jumps dramatically. It won’t give you VLANs or enterprise-grade roaming, but for most 3,000– 4,000 sq ft homes, wired-backhaul Eero is roughly 80% of what UniFi delivers at a fraction of the effort.
This is often what we recommend for a house that’s already got Eero and just wants it to work better. Once the homeowner is ready for cameras, access control, or proper segmentation, the Cat6 we ran to each Eero node becomes the backhaul for a UniFi AP later.
The Utah-specific stuff
A few things we’ve learned doing these installs across the Wasatch Front:
- Log and timber construction in Park City, Promontory, and Deer Valley attenuates both bands aggressively. Mesh kits rarely survive a real mountain home; wired APs are essentially required.
- Utah builder floor plans in Herriman, Bluffdale, and Eagle Mountain typically have a central great room with tall ceilings — one ceiling AP above that great room covers most of the main floor at full speed.
- Basement finishes (common in Sandy, Draper, and Cottonwood Heights) need a dedicated AP in the basement ceiling. Any mesh node at the top of the stairs is backhauling through a concrete slab — which is a losing fight.
- Builder pre-wire packages often include Cat6 to each bedroom but no ceiling drops for APs. If you’re still in the build phase, ask for ceiling drops at AP locations — we covered this in the new construction pre-wire checklist.
Bottom line
For a 4,000 sq ft Utah home with two or three floors, heavy-construction elements, and a modern device count, three Eeros on wireless backhaul is going to disappoint you. Either wire the Eero nodes (good middle path) or install a proper wired UniFi stack with ceiling-mounted APs (best result). The difference shows up immediately in the basement bedroom, the master suite, and anywhere you’re asking Wi-Fi to cover more than 40 feet through two walls.
The cost gap is real but smaller than people think: about $600–800 more in hardware, plus a day of labor to pull Cat6 to the AP locations. For a house that will be running 50+ devices for the next decade, that’s a one-time investment against a network that never needs an apology.
