Better Wi-Fi Starts With Measuring It

When the Wi-Fi is bad, most people buy something. A bigger router, an extender, a mesh kit from the big-box store. Sometimes it helps. Often the problem just moves to a different room.

That happens because "the Wi-Fi is bad" can mean several different things, and often it's more than one of them at once. Each has its own fix. So before we recommend a single piece of equipment, we walk the house and measure it.

What "bad Wi-Fi" usually turns out to be

• Weak signal. The access point is too far away, or something is in the way. Brick, stone, plaster, mirrors, appliances and floors all soak up Wi-Fi. In Oklahoma, so does the concrete storm shelter or safe room many homes have.
• Too much competition. Your network shares the air with every neighbor's network, and each one takes a turn talking. In a neighborhood, the 2.4 GHz band is usually crowded.
• Channels stepping on each other. In the 2.4 GHz band only three channels (1, 6 and 11) don't overlap. Put two networks on overlapping channels, or set your own access points badly, and they interfere with each other.
• Devices that can't join at all. The network is fine, but it's using settings some of your devices don't support. More on that below, because it's the one people miss most.
• It isn't the Wi-Fi. Sometimes the inside of the house is healthy and the problem is the internet line coming in.

Most homes have more than one of these going on at the same time, and they all feel the same from the couch. That's why we measure instead of guessing.

Step 1: Walk the house with NetSpot

Our assessment tool is NetSpot, professional Wi-Fi survey software. We load a floor plan, walk the house room by room taking measurements, and NetSpot turns those readings into heatmaps of your home. The goal is to give you a map rather than an opinion.

We start in NetSpot's Inspector view. It lists every network our laptop can hear, yours and your neighbors', with the channel, band, channel width, signal strength and security type of each. Within a few minutes it's usually clear whether your network is fighting three neighbors for the same channel.

Then we run the survey. The heatmaps we look at most:

• Signal level: where coverage is strong and where it falls off. These are your dead spots.
• Signal-to-noise: whether your signal is strong enough to stand out from the background noise. A room can show "full bars" and still perform badly if it's noisy.
• Signal-to-interference: where networks on the same or overlapping channels collide. This is how we find channel overlap, including your own access points interfering with each other.
• Band and Wi-Fi standard coverage: which parts of the house get the faster 5 GHz band and newer Wi-Fi standards, and which fall back to slower ones.

We also count network names (SSIDs). Most houses broadcast more of them than the owner realizes: an old extender, the internet provider's router still broadcasting after someone added their own, a printer's setup hotspot. Every extra network competes for airtime. We check outside too, at the patio, pool, garage and any detached building, because that's where people expect Wi-Fi now.

Step 2: Fix the free stuff first

A surprising amount can be fixed without buying anything. We can move networks to clean channels, narrow channel widths in the crowded 2.4 GHz band, and turn off Wi-Fi on the provider's router so it stops competing with your real network. We can move an access point out of a cabinet or off the floor, and turn down transmit power so access points stop shouting over each other.

Then we survey again. If the heatmap says the problem is solved, you're done, and we'll tell you so.

Step 3: Choose the right hardware: mesh or wired access points

When a home does need new equipment, the first big decision is mesh or wired access points.

We'll be honest: we're not big fans of wireless mesh for most of the homes we work in. Mesh units talk to each other over the air. Every one of those wireless hops uses airtime your devices also need, so performance tends to drop the farther you get from the main unit. Mesh is quick to set up, and in a smaller home where running cable isn't practical it can be a reasonable choice. In a larger home full of smart devices, it's usually a compromise.

Wired access points work differently. Each one gets its own Ethernet cable back to a central switch, which also powers it (that's Power over Ethernet, or PoE). The only wireless part is the last few feet to your phone or TV. The access points mount cleanly on the ceiling, and one app manages them all. Where a cable truly can't reach a spot, we can use a wireless link for that one location and keep the rest of the network wired.

Once you've decided to go wired, the next question is which platform. We're vendor-agnostic, and these are the three we install most often for homes:

• TP-Link Omada. Strong value, with a full lineup of access points, PoE switches and gateways managed from one cloud dashboard. A good fit for most homes that want wired access points without top-tier pricing.
• Ubiquiti UniFi. A polished management app and a broad ecosystem that also covers cameras and door access, so it works well when you want those on the same platform. We're a Ubiquiti Professional Integrator.
• eero Pro and eero PoE. eero's familiar, simple app, now on wired, ceiling-mount access points like the eero PoE 7. A great fit for homeowners who want simplicity above all. We're an Amazon eero Professional Installer.

Which one is right depends on your home's size and construction, whether cable already exists or can be run, how many devices you have, what else you want on the same system, and who will look after it. The survey answers the practical part: it shows us how many access points you need and where they belong.

Step 4: Make sure everything can actually connect

This is the step that gets skipped most often, and it causes some of the most frustrating problems.

New Wi-Fi equipment ships with impressive features: the newest security, Wi-Fi 7 extras, clever roaming. They look great on a spec sheet. But garage door openers, thermostats, sprinkler controllers, smart plugs and a lot of other smart home devices use older, simpler Wi-Fi chips, and many only work on 2.4 GHz. Turn on the wrong combination of settings and those devices don't drop off the network. They never get on in the first place.

The usual culprits:

• WPA3-only security. Many older devices can't join. A mixed WPA2/WPA3 mode, or a separate WPA2 network for those devices, usually solves it.
• Wi-Fi 7 multi-link and other newest features. Older devices can struggle with them, so we turn them on where they help and off where they don't.
• One name for both bands. Some devices need to see a 2.4 GHz network during setup and get confused when the router steers them. A 2.4 GHz-only network fixes that.
• Fast roaming and strict security extras. Features like 802.11r roaming and required management-frame protection are great for phones and laptops and can make some older devices drop.

The fix can be dramatic. In one recent home, adjusting these settings took the network from 5 connected devices to 33, without changing the network name or password, so nothing had to be set up again.

Step 5: Give smart devices their own network

In most homes we set up a separate network just for smart devices (often called an IoT network, for "Internet of Things"). Cameras, thermostats, TVs, garage openers, smart plugs and appliances go there. Your phones, laptops and work computers stay on the main network. Guests get their own network too.

This does two things. It keeps an inexpensive smart plug with weak security from sitting right next to your work laptop. And it lets the smart devices use the compatible settings they need while your main network keeps the newest security.

There's one catch, and it's where a lot of do-it-yourself setups go wrong. Things like casting to a TV, AirPlay, HomeKit and whole-home audio need your phone to find devices on the network. Split the networks without planning for that, and your phone can no longer see the TV. We configure the network so those discovery messages still get through, without opening everything else back up.

Step 6: Survey again, and write it all down

After installation we walk the house with NetSpot again and compare the before and after heatmaps, so you can see the difference yourself.

Then we document everything: each access point and switch, the network settings, and every connected device, labeled with what it actually is and where it lives instead of a string of letters and numbers. Passwords go in an encrypted vault the homeowner can reach whenever they need them. If someone else ever works on your network, they'll know exactly what's there.

And sometimes it isn't the Wi-Fi at all

Sometimes all of this is step one of a bigger question. In a recent home, the owner was sure his internet provider was the problem after a lightning strike. Before we could answer that, we had to get every device connected properly, document the network, and only then start measuring the internet line itself. You can read how that went in It Wasn't the Internet. Not Yet, Anyway.

Dead spots, smart devices that won't stay connected, or about to buy a mesh kit and want a second opinion? Schedule an in-home assessment. We serve Edmond, Oklahoma City and the surrounding metro, and we'll start by measuring.
