Home Network Setup for Best Wi-Fi Coverage and Performance: The Quick Tips

Share what you're reading!

Recently I’ve received a lot of questions about getting the best Wi-Fi coverage — stuff I’d already covered a great deal. Some even complained that there was just “too much” information in my posts. “It’s overwhelming,” they said.

Everyone wants the best Wi-Fi coverage with the least amount of effort!

So this post is where I point you in the right direction with links to other detailed pieces on the subjects, just in case. It’ll save you time. And I plan to update it regularly.

A bit of warning: You might get overwhelmed by the number of related posts.

Best Wi-Fi Coverage and Performance a Wi-Fi Router and Modem
Best Wi-Fi Coverage and Performance: Here are a Wi-Fi Router and an Internet source — a cable modem in this case. We need both.

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.

That said, let’s start with a few seemingly-obvious items we often overlook that might lead to unnecessary Wi-Fi issues. The entire post only makes sense if you read this part.

1. Wi-Fi and Intenet are two different things

I remember leaving an Airbnb review recently and putting “excellent Wi-Fi” as one of the positive notes. Well, by that, I meant the place had fast Internet. I’m sure you can relate to how we tend to use one to mean the other.

But in reality, Wi-Fi and Internet are two different things. We need to keep that in mind when troubleshooting or setting up a new network.

If somehow you actually don’t know that, this post will explain them in detail. But the most important thing to keep in mind is this: getting a new Wi-Fi router does not necessarily improve your online experience — that’s on your Internet.

Internet vs Wi-Fi: They are two different things

2. Wi-Fi coverage is a sphere

Ideally, a Wi-Fi broadcaster (a Wi-Fi router or access point) broadcasts signals out omnidirectional β€” it’s like a light bulb or the sun.

That means the coverage is somewhat like a sphere with the emitter in the center. (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.)

I wrote a long post on antennas, dBi, Wi-Fi, and FEM, you might want to check it out.

3. Wi-Fi is invisible and its range is hard to predict

The diameter of the sphere, in any direction, is a Wi-Fi broadcaster’s range. 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. Also, the signals don’t die abruptly but wane slowly, and they are only meaningful when a device can connect to them at a certain speed — the detectable range is much longer than the useful one.

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.

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. 

That said, it’s worth noting that Wi-Fi is invisible and has a high level of unpredictability. If you treated it as something you can see or touch, like a car, it’d make no sense to you. This post will walk you through the intricacies of Wi-Fi as a whole.

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.

And that brings us to what we can do to optimize a router’s coverage.

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 by far the best way to get the Wi-Fi coverage you need. 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. 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.

What you might not know is that wiring can be quite fun.

2. 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.

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

Common Wi-Fi placement rules

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

If you need to use multiple broadcasters — like a router and a few access points or mesh satellites — arrange them in a way 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 total nonsense!)
  • Keep its antennas, if any, in the vertical position, and 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 where 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 placement of the hardware can be tricky. But generally:

  • Place the satellite around the main router.
  • Use a Tri-band broadcaster — one that has an additional 5GHz band to work as the dedicated backhaul. If you want Wi-Fi 6E, use Quad-band hardware.
  • The satellite should be at the ideal distance from the main router where its signal is around -70 dBm in strength.

3. Cut down the number of legacy and β€œsmart” Wi-Fi devices

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

  • Avoid using no-name Wi-Fi smart devices
  • Use Smart Home devices that have a separate hub, which is the only Wi-Fi device involved.
  • Use a separate Wi-Fi network (access point or band) for these devices.

If you want to know the real reason 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

Amcrest IP camera Square
Best Wi-Fi Coverage and Performance: IP camera, such as this 2.4GHz-only one, is an example of what you want to avoid mixing with high-end clients, or get a separate access point.
(I’ve used this particular unit for some 5 years and it was quite cutting-edge when it was first available. Newer models are all dual-band.)

4. 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 give you the option of creating 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 gives you the convenience of not having 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 have to work in compatibility mode, which is never a good thing.

Guest Wi-Fi: It’s all about isolation

5. 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. That’s because 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 just so that you have “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

6. Prioritizing your bandwidth

No matter how fast your Internet has limited bandwidth, a single device can use all of that in a specific task.

For example, when you download a large file, the process will use all available Internet bandwidth 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.

7. Getting the right hardware

Getting yourself a new Wi-Fi router or mesh system is a consequential task and a tricky one. Everyone has different needs.

This task is easy only when you live in a small house, preferably alone, with slow Internet. But if you do, then chances are you’re not reading this right now. 

Again, since there’s no one-size-fits-all solution, I’ll offer here some general bullet points for you to consider:

  • Don’t be “cheap”: The Wi-Fi router is the most important gadget in your home — it’s like running water. Spend money where it matters. 
  • Size matters: You don’t need a humongous router, but 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 β€” though not always, they tend to be bulky, ugly, or even slightly noisy, or all of that. Pick a combo you can tolerate
  • Avoid 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 at farther than 40 feet (12 m), in most cases.

Best Wi-Fi 6 routers: The best options to buy right now

Also, consider these when you need multiple broadcasters, such as in the case of a mesh system:

  • If you can’t run network cable, a tri-band system β€” one with an additional 5GHz band β€” is a must. (If you use Wi-Fi 6E, then it must be a quad-band system.)
  • If you have wired your home with a network cable, then get dual-band hardware (tri-band if you go with Wi-Fi 6E). Or you can also get a few access points.
  • Don’t believe in the hype of Wi-Fi 6E. This latest standard is only good for a wired system and you need new clients, too.
  • Avoid getting Wi-Fi extenders (or the so-called β€œboosters”). They almost never will work out.

Extra: Tips on getting the most out of your broadband connection

In land-based broadband access, you generally have two options Cable vs Fiber-optic, of which the terminal device is a modem or an ONT, respectively. The former is more affordable but generally has a slow upload speed.

Fast broadband: Understanding Cable vs Fiber-optic

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

  • Get a standalone terminal device (modem or ONT)
  • Avoid combo gateway, which is a Wi-Fi router with a built-in terminal device. The new xFi Advanced Gateway from Comcast is an example.
  • For cable: pick the right modem for your speed grade.
  • For Fiber, have the ONT installed at a good place in your house — see placement above.
  • For cable: 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.
  • When possible, use your own equipment instead of renting one from the provider.

The takeaway

Among the challenges of being at home all the time, keeping everyone in the house happy and happily connected ranks at the top — they are daily matters.

After years, I still have yet to find an enduring solution for the former, but hopefully, the tips above will help you make the most out of your existing Wi-Fi or set up a new network at its best. Doing well on this front helps the other, too.

That said, keep in mind that networking is always complicated.

To get a solution that gives the best Wi-Fi coverage and performance for yourself, you need to understand your home’s layout, what you need, and how Wi-Fi works. Yes, it’s kind of like looking for a partner — as in the other type of networking — only with much lower risks, financially and especially emotionally. 

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?
