Building a Home Wi-Fi Network Correctly: Understanding the obvious

Since Wi-Fi is a complicated realm β€” there's no one-size-fits-all β€” it's a good idea to understand its nuance.

Let's start with a few seemingly-obvious items we often overlook that might lead to unnecessary Wi-Fi issues.

1. Wi-Fi and the Internet are two different things

If you've read some user reviews somewhere about a venue and run into comments about its Wi-Fi, know that the reviewer means Internet access. Folks often use one to tell the other.

And most of the time, that's OK. But when troubleshooting or setting up a new network, knowing that Wi-Fi and the Internet are two different things is imperative.

Specifically, getting a new Wi-Fi router does not necessarily improve your online experience -- that's on your Internet.

Internet vs Wi-Fi are two different things

2. Wi-Fi coverage is a sphere

Ideally, a standard Wi-Fi broadcaster (a Wi-Fi router or access point) broadcasts signals omnidirectionally -- like a light bulb or the sun.

That means the coverage resembles a sphere with the emitter in the center. However, in reality, it's more like an egg in most cases, or even less ideal than that β€” it's impossible to have a perfect orb -- but you get the idea.

That said, you generally can orient a broadcaster however you see fit. If you want to know more about Wi-Fi signals, check out the posts on dBi and dBm below.

Wi-Fi coverage: dBi vs dBm

Wi-Fi dBi and high-gain antenna explained: Antenna coverage and dBi (for illustration purposes only.)
Best Wi-Fi Coverage and Performance: All home Wi-Fi broadcasters (router or access point) use low dBi and broadcast signals as a sphere. And that's a good thing.

3. Wi-Fi range: What you see is not what you get

The diameter of the coverage sphere, in any direction, is a Wi-Fi broadcaster's range -- how far its radio waves can travel outward. So the million-dollar question is, what's the length of this diameter?

There's no exact number. It varies depending on the environment, the hardware, and the Wi-Fi band. At any given time, there can be a lot of invisible stuff in the air hindering the radio waves.

Generally, the lower the GHz in frequencies, the longer the range but the slower the speed. In my experience, Wi-Fi 6's 2.4GHz band has almost double the range of the 5GHz band but is just a fraction of the real-world rates.

The new 6GHz band continues that trend. It has about two third of the 5GHz range.

So here's my general real-world estimate: out in the open, you can expect a home Wi-Fi 6 router's effective range β€” that's when you can still get a good connection using a typical receiver like your phone β€” to be around 75 feet (23m) to 150 feet (46 m), depending on the hardware. 

Inside, though, each wall or large object will decrease the range by 10% to 50%, in that direction, depending on the material and thickness. 

With that, here's our jump-to-conclusions mat.

Tips on building a home Wi-Fi network correctly: Hardware purchase

Getting the right hardware is the most important thing to build a robust home Wi-Fi network. Below are three tips on getting the correct hardware parts for your network.

Cable Modem vs Fiber ONT
Best Wi-Fi Coverage and Performance: A Cable modem (top) and a Fiber ONT

1. Own, don’t rent, your broadband terminal device

In land-based broadband access, you generally have two options, Cable or Fiber-optic, of which the terminal device is a modem or an ONT.

DSL is similar to Cable, and satellite or cellular is similar to Fiber-optic.

But no matter what you get, here are a few suggestions:

  • Get a standalone terminal device (modem or ONT)
  • Avoid combo gateway, a Wi-Fi router with a built-in terminal device.
  • When possible, use your own equipment instead of renting one from the provider.
  • For Fiber, have the ONT installed at a good place in your house -- more in the placement section below.
  • For Cable Internet:
    • Pick the right modem for your speed grade, but it's always safe to get a DOCSIS 3.1 modem with a Multi-Gig port.
    • Use just the Internet, and remove all TV or phone options. After that, use streaming, such as YouTube TV, and a separate VoIP phone service.

2. Getting the right hardware: Single router vs mesh system

A mesh system (which consists of multiple broadcasters) is not an upgrade to a standalone router but a necessary alternative. It's best to have just one broadcaster within a home to avoid interference.

That said, one router is enough if you live in a medium or small home. As for which one to get, that depends on this post on routers will explain more. But it's safe to get one on the best lists below.

Router best lists: Wi-Fi 6 | Wi-Fi 6E

On the other hand, getting a mesh can be very complicated. As I explained in this post on Wi-Fi systems, there's no one-size-fits-all solution. Here are a couple of things to keep in mind:

  • If you're using an ISP-provided gateway:
    • Consider replacing it with a terminal device -- Fiber-optic ONT or Cable modem -- or turning it into one via the bridge mode. Or
    • Extend its coverage via an access point or an extender.
    • Consider a double NAT setup.
  • If your home is wired with network cable: Consider Dual-band Wi-Fi 6 or Tri-band Wi-Fi 6E hardware. (Wired backhauling is the only way to get the best-performing network -- more below.)
  • If you need a fully wireless system:

Below are the links to the current best mesh systems.

3. The three don’ts in getting Wi-Fi equipment

When getting new Wi-Fi hardware, keep these three don'ts in mind:

  1. Don't be "cheap" or go for "future-proofing".
    • The Wi-Fi router is the most important gadget in your home -- it's like running water. Spend money where it matters, and don't use cost as the main factor in picking hardware. 
    • Contrary, you shouldn't waste your money on "future-proofing." There's no such thing. Get the equipment that works for you today.
  2. Don't fall for "cute": While the look can play a role -- I've gotten quite a few comments from men complaining about the "wife acceptance" issue with particular routers -- it's important to note that size does matter in Wi-Fi. While you might not need a humongous router, tiny, cute compact devices will never give you good performance and range. It's just physics. A fast, powerful router needs to be of a certain physical size. Though not always, they tend to be bulky, ugly, or even slightly noisy, or all of that. Pick a combo you can tolerate.
  3. Generally, don't get vendor-dependent devices: Specifically, I'd stay away from hyped-up, and highly sponsored/affiliated Google Wifi/Nest, eero, and alike. Their requirements (login account, live connection with the vendor at all times, etc.) can translate into privacy risks. But most importantly, they are just too small to deliver fast performance. In fact, none of their current variants can reliably deliver faster than 300Mbps of sustained Wi-Fi rates at a distance.

Notes Wi-Fi equipment: When to replace yours | Your privacy matters

Tips on setting hardware for the best Wi-Fi coverage and performance

These are general tips. Some apply to all situations; others are only to specific homes.

1. Run network cables

It might sound counterintuitive, but getting your home wired is the best way to get the optimal Wi-Fi coverage. That's especially true if you're thinking of going Multi-Gig and getting 2.5Gbps, 5Gbps, or even 10Gbps connections.

Sometimes you need to run only one cable. For others, you might want to wire the entire home. In any case, network cables will give you the most options for the best Wi-Fi coverage and performance.

For a home already wired to a cable TV network, you can use MoCA adapters to turn the coax wires into a network cable.

Running network cables is the only way to have the best Wi-Fi coverage and performance in a large home.

2. Proper placement

After wiring, placement is the second most important in Wi-Fi setup. That said, it's the most important for those who can't run wires.

Common Wi-Fi placement rules

Considering the sphere notion above, it's best to put your Wi-Fi broadcaster (router, access point) close to the center of the area you want to blanket.

If you need to use multiple broadcasters -- like a router and a few access points or mesh satellites -- arrange them so that their combined spheres cover the entire house.

No matter where you can place your broadcaster, make sure:

  • Keep it out in the open
  • Don't cover it with anything. (The aluminum foil idea you might have heard of is nonsensical!)
  • Keep its antennas, if any, in the vertical position, then leave them alone.

Wi-Fi placement rules: Wired vs wireless

Sometimes, running a single network cable helps a lot. For example, you can use the cable to connect your modem or Fiber ONT, which tends to be at a corner of the house, to the best place you want the router to be.

Or, if you use a mesh system, run a cable to link the router at one corner of the house and the satellite at another to form a reliable and strong backhaul connection between the two.

If you use a mesh system in a fully wireless setup (no network cable involved), the hardware placement can be tricky. But generally:

3. Other tips for the best Wi-Fi coverage and performance

Below are additional general tips you can do to keep your home Wi-Fi network at its best.

Cut down the number of legacy and “smart” Wi-Fi devices

Wi-Fi Internet of Things (IoTs) devices often use dated Wi-Fi standards and can bog down a modern Wi-Fi 6 (or later) router. That said, consider the following:

  • Avoid using no-name Wi-Fi smart devices
  • Use Smart Home devices with a separate hub as the only device that connects directly to your network (via Wi-Fi or a wired connection.)
  • Use a separate Wi-Fi network (access point or band) for these devices.

If you want to know why using dated Wi-Fi clients is no good, I detailed that in this post on Airtime Fairness.

Airtime Fairness: It's not really fair

Separate the bands

When possible, separating the Wi-Fi bands instead of using "Smart Connect" gives you more control of the network. You can segment the network accordingly. Such as:

  • Delegate the 2.4GHz band to slow devices.
  • Put fast devices on the (first) 5GHz band.
  • Connect mixed 5GHz devices to the second 5GHz band (if available).
  • Use the 6GHz band (if available) exclusively for fast clients.

On top of that, many routers also enable you to create virtual networks out of a single band, such as a Guest network. You can use them for this purpose.

Using all of the bands as a single network allows you not to have to reconnect when you move far from the router. The 2.4GHz band has the best range, but it tends to cause more bandwidth and performance issues, in my experience.

At the very least, all bands must work in compatibility mode, which is never good.

Guest Wi-Fi: It's all about isolation

Turn off VPN when not needed

If you work from home and need to connect to your office, then VPN is helpful. Sometimes, it's a requirement. A VPN allows your device to be part of a remote network securely. For the same reason, VPN is also useful when you travel.

However, when you don't need to be part of a remote network, using a VPN will only worsen the connection's speed, not to mention the privacy risks – your device's online activities go through the VPN server.

That said, when you're at home and use a third-party VPN for "better security," you should consider turning it off or removing it. You're probably fooling yourself at the expense of your connection speed and privacy, not to mention the monthly cost.

Virtual private network: How to use VPNs properly

Prioritizing your bandwidth

Generally, a single device can hog all of a sub-Gigabit broadband bandwidth.

For example, when you download a large file, all available Internet bandwidth will be used until the task is complete. During this time, other devices might have problems staying connected. That's especially problematic when you're on a video call.

That's where a feature called QoS, or Quality of Service, comes into play. QoS helps prioritize the Internet bandwidth at a device or application level. A good router always has this feature built-in.

The takeaway

Networking is always complicated. Hopefully, you have figured out where to jump by now.

Simply put, you must understand your home's layout, what you need, and how Wi-Fi works to get a solution that gives you the best coverage and performance. Come to think about it, getting a Wi-Fi solution can be as complicated as looking for a partner -- both are networking -- albeit with much lower financial and emotional risks. 

In any case, remember: you never get everything. I speak from experience.

  1. Hi Dong, great web & article!
    From time to time I come here and let you give me some advice. I bought a pair of xd4s several years ago, traded them in for xe75s (which I’m still testing and due to a problem with the automatic channel selection, I think I’m going to return them, but they would be great with more configuration options), now I’m trying the XT8s which I think I’ll keep because they give me more control. Always all of them with wired backhaul.
    My point is, in the article you recommend separating the bands, which I have tried and it works fine. But it seems to me that you lose a lot of versatility. In the XD4 I tried to control the connection of the devices to each band in two ways, using the smart connect rule(PHY Rate less/greater) or with the MAC filter by setting the devices that I didn’t want to connect to 5ghz to reject. I think the first option is more elegant but both worked quite well on the XD4. Now I want to try it on the XT8, but as it is a triband, it is not so clear how to configure the smart connect rule. Could you help me with it or do you plan to make an article on how to configure it?
    Thank you and sorry for the long-windedness.

    • The XT8 is not ideal with wired backhauling, Miguel. Use the ET8 instead. Also, keep separating the bands if you want more control. Band-steering is extremely complicated.

      • I couldn’t find an ET8 here in Spain.
        About the xt8, I’m using firmware 386, last one and it’s working perfectly. Do you think I will have problems with wired bachaul Dong?

  2. Great site, excellent resource, thank you.

    As to placement of router and mesh nodes, what about the vertical placement? Best on the floor, mid height or mounted on the ceiling?

  3. Dong, good article. Much appreciated.

    When it comes to a Mesh setup in a home, is it better to stick with buying an additional satellite from the same brand to avoid interference? To clarify with an example:

    If I setup a ASUS Zen Mesh system, or Netgear Orbi Mesh with a router and 1, or 2 satellites in either case, and then discover there isn’t quite enough reach, or a dead spot, then:

    1. Should I stick with getting an additional Zen satellite (or Orbi in the Netgear setup)
    2. Is it possible to add in two Amplifi Alien units (1 to plug into the furthest outpost of the existing mesh system and another Alien to act as the additional node)

    I guess I’m asking if you end up with Wifi interference by having an Alien network set up alongside. Maybe it’s just because the Alien looks cool, but buying two Aliens I think comes out cheaper than buying an additional Orbi satellite ironically?!

    Would appreciate your advice, thanks!

  4. Dong, really appreciate this resource, I’ve been reading for months. I’m covering a large home multigenerational home, about 8000 square feet and one 5000 square foot outbuilding (steel walls/roof, this building is using a wireless link). I went Asus early on and have used your recommendations for tuning the setup.

    I am running an rt-ac86u as the primary on Merlin. I have 3 Lyra ac2200 wired. The 50′ link to the outbuilding was using a wired lyra to an merlin rt-ac68u(tm-1900) in a window. This setup took some trial and error with the lyras and for whatever reason using the 68u as the end of the wireless link worked the best. Very strong signal and weather/vehicles did not affect the link. Wired Lyra to wireless Lyra was the worst solution by the way. I have to return the 68u to Tmobile and it’s breaking my heart because I finally had a solid setup. I have an ac3100 and a rt-ac87u waiting in the wings, I’m just not sure what configuration would be recommended. I am going to try the ac3100 as the wired end to the 87u in the outbuilding first. The lyra’s are good, but not great as far as range and are a little unreliable as far as signal drops and reconnect. I have about 80 clients on the network, with a mix of smarthome stuff and wired poe cams. Probably a near perfect split of wired/wireless. Now for the question: 1. suggestions on the 87u/ac3100/lyra layout? 2. have I jumped the shark on aimesh? I feel liek I’m right on the edge of consumer devices and may need to bite the bullet on ubiquiti or something else. 3. Have you thought of charging a consulting fee? I’d pay for some advice and a coupleof emails back and forth – and it might cut down on the bandwidth of questions you get. I do enjoy learing from the questions and your answers). Thanks in advance!

  5. I have/had Spectrum and my home was wired for their IP phone system, Cat 5. I went to the central location and installed a patch panel. I bought a cat5 multi tester. Amazing. I only had to install that panel as the outlets were already T568 configured. I labeled each drop on the panel and walla, my house is wired.
    I bought an ASUS GT5300 and was wondering if you have any advise what I should use for the wired device.

  6. Great article and fantastic site! I’ve gone down many rabbit holes on here.
    I have a question about router placement for best Wi-Fi performance, I’ve always thought (read somewhere?) to place the routers (and mesh points) as high up as possible in a room to get the best Wi-Fi performance.
    Do you have an opinion on this?

  7. I have set up a wired Asus Zenwifi ax6 and am feeding it with a bridged Comcast Gateway Gig Modem. I am a little disappointed with the fluctuating speeds on devices. I have an LG Oled which will show a speed of 79mbps one day and then 379mbps the next. I thought perhaps adding one more Zen might make some difference. Any ideas?
