If you're dealing with dead zones, buffering, or dropped video calls, you've probably Googled "how much does WiFi installation cost?" The answer depends on your home, but here's an honest breakdown from a company that installs professional WiFi networks every day across Rhode Island, Massachusetts, Connecticut, and New Jersey.
Most residential WiFi installations cost between $500 and $3,000. A small apartment or condo might be on the low end. A 4,000+ square foot colonial with plaster walls and three floors will be on the higher end. The biggest cost variables are how many access points you need and whether new ethernet cable needs to be run through the walls.
Each access point covers roughly 1,000–1,500 square feet of open space, or 500–800 square feet through walls. A typical 2,000 sq ft home needs 2–3 access points. A 4,000+ sq ft home needs 4–6. Each Ubiquiti UniFi access point costs $100–$300 for the hardware, depending on the model.
This is usually the largest cost component. Running CAT6 ethernet cable through finished walls requires cutting small holes, fishing cable through wall cavities, and patching everything clean. Expect $150–$400 per cable run depending on difficulty. A 3-access-point install might need 3–4 cable runs.
If your home already has ethernet wiring (some newer builds do), this cost drops dramatically. We always check during our free assessment.
Older New England homes — the plaster-and-lath colonials common across Providence, Warwick, and the Massachusetts suburbs — are harder to wire than modern drywall construction. The plaster is dense, the wall cavities are irregular, and there's often no attic or basement access to fish cable easily. This adds labor time, which adds cost.
Beyond access points, most installs include a PoE (Power over Ethernet) switch and sometimes a new router or gateway. A complete equipment package typically runs $300–$800 depending on what you already have and what needs upgrading.
You can buy UniFi equipment yourself — it's not locked to dealers. But the value of professional installation is in the wiring and configuration. Running ethernet through finished walls is a skilled trade. Getting access point placement right requires an RF site survey, not guesswork. And configuring VLANs, band steering, and roaming thresholds correctly is what separates "it works" from "it works perfectly."
We've seen plenty of homeowners buy mesh systems, return them, buy different mesh systems, and repeat — spending $600+ on hardware that never solved the problem. A professional installation costs more upfront but it's a one-time fix that lasts 5–10 years.
