How to Pick that Perfect Router for Your Situation

It's always hard to pick the best Wi-Fi router: Netgear RAX200 RAX40 TP Link Archer AX50
Dong Ngo | Dong Knows Tech The first step in knowing how to pick the best Wi-Fi router for your home is finding out what a router can or cannot do.

This post aims to set your expectations right and help you figure out how to pick the best Wi-Fi router in your situation. I’ve already written quite a bit on this topic — you’ll find links here — but there’s a reason for writing this one. And it’s a long piece, too.

What’s the deal, Dong?

A big part of the emails galore I get daily includes those asking for a specific router or mesh recommendation. Some readers even sent me a detailed sketch of their home — you know who you are!

I hate ignoring people and entertain many of those emails. And that generally works out. Sometimes it doesn’t, though.

A couple of days ago, I got a message from John — not his real name — telling me semi-jokingly that he blamed me for how his wife was unhappy. “Your recommended router didn’t work as we had hoped, and I’m now in big trouble!” he said.

It’s all about networking

And with that, it just reoccurred to me something I’ve always thought of getting a Wi-Fi router: It’s similar to finding a partner — as in dating. Both are networking after all.

So, I’m going to answer in this post questions that give additional information relating to how to pick the best Wi-Fi router. It’s a good idea that you read post on building a network from scratch, first.

There’s no guarantee but when you’re through with this, chances are you will be able to pick the right one, by yourself, at the first try.

A closer look at a home Wi-Fi router

To pick the right Wi-Fi router, you first need to understand its capabilities and its limitation. But there’s one thing all routers have in common which is the primary function of creating a local network for multiple devices to work together.

How many devices can a home Wi-Fi router support?

Technically, a home router can host 254 devices, including itself.

(That’s because IPv4‘s subnets max out at 255 with one address being used for a special purpose. But that’s too much unnecessary technical detail, don’t you think?)

So you can expect to connect up to 253 devices to a home router. Realistically, though, the number of devices you can use in a home simultaneously will be significantly lower. It’s a matter of bandwidth.

Wired bandwidth

A home router tends to have just a few (usually four) LAN ports. This number of ports translates into the total amount of wired devices the router can handle concurrently.

Yes, you add more devices to the network via a switch. But in this case, the switch itself adds more bandwidth. Two devices connecting directly to a switch will use the switch’s resources, and speed grade, for the connection between them. In this case, other than providing the IP addresses, the router doesn’t do much more.

That said, if you choose to run network cables and are willing to add a couple of switches, your network can host all 253 parties at the same time no problem.

The thing is we don’t have that many wired devices. In fact, a home Wi-Fi router nowadays mostly serves as a Wi-Fi broadcaster.

Wi-Fi bandwidth

You can read more on Wi-Fi bandwidth in this post about dual-band vs. tri-band. However, the gist is that each Wi-Fi frequency band’s ceiling speed is actually its total bandwidth.

So for example, on paper a 5 GHz 4×4 Wi-Fi 5 band caps at 1733 Mbps. That’s its ceiling speed when there’s only one connected client. If you have 10 active clients, each will cap at 173.3 Mbps, or 86.65 Mbps with 20 active clients, and so on.

As you can imagine, on the Wi-Fi front, a router can handle only so many active clients at a time. So, it’s still a good idea to get a top-tier or tri-band router even though you might have all mid-tier clients. That’s especially true when you have super-fast Internet.

Generally, a single home Wi-Fi router, even a top-notch one, can handle no more than 100 active clients — most vendors recommend 50 or fewer. Note, though, that only active devices use up the router’s bandwidth.

Does using a mesh system means you can use more concurrent clients

You can find out more in this post about mesh systems but generally, the acceptable total amount of active devices depends on the mesh’s hardware and the way you set it up.

Dong Ngo | Dong Knows Tech Picking the right Wi-Fi router: More hardware units don’t necessarily translate into more bandwidth.

Similar to a switch, each mesh hub does have Wi-Fi bandwidth of its own. However, all devices connected to a mesh point share the same bandwidth of the backhaul link, which connects the hub to the network.

In a wireless setup, the backhaul link of a dual-band mesh system has much less bandwidth than that of a tri-band system, and a mesh system using wired backhaul will have the most bandwidth.

Generally, assuming we’re using hardware of the same Wi-Fi grade, and if your clients are spread out equally in between the mesh points, then your mesh network sure can handle more concurrent clients than when you use a single router.

But a mesh system, which is essentially a router with a few extenders, still has a cap of 253 devices. And in reality, you probably should have only half of the amount.

How can I limit the amount of clients in a local network?

Each router comes with a fixed IP address pool that determines the number of clients that can connect to the network. By default, some routers set this at 50, others at 100, or even all 253.

But generally, you can change this value via the router’s DHCP server setting. Just log in to the router’s web interface (or use its mobile app), navigate to the LAN section, and change the value of the IP Pool Starting Address and IP Pool Ending Address accordingly. Note that the wording of these two might vary slightly between networking vendors.

Dong Ngo | Dong Knows Tech These settings of the HDCP Server will allow 253 devices to connect to the network. Note the first IP address, 192.168.2.1, is reserved for the router itself.

These values are the last group of digits in the router’s IP address pool, which ranges between 2 and 254. Subtracting the starting number from the ending number, then adding 1 to the result will give you the number of total clients that can connect to the router.

So, pick the number that works for your situation. Just make sure the starting address is lower than the ending one and the range of the two must not include the address of the router itself.

IP address assignment: Dynamic vs. manual

Note, though, that this address pool is not super strict and only applies to clients that get an IP address dynamically via the router’s DHCP server function, which happens right after you plug a cable into a device or enter the Wi-Fi password. It doesn’t affect manually assigned addresses.

So, for example, if you set the IP pool in the 192.168.2.100 and 192.168.2.200 range, you can manually set an IP of a client to be 192.168.2.99. That client will still connect to the router successfully, as long as there’s no other device already with that IP address.

Unless there’s a specific reason, it’s a good idea not to assign an IP manually, which is quite a pain to do anyway. If you need to make sure a device always gets the same IP address, you can use the router’s IP reservation feature instead.

What if I want to provide the Internet to more than 253 devices?

While you can’t use more than 253 devices in a local home network, you sure can share a single Internet connection to unlimited parties.

It’s quite simple, just add more routers to the network, using double NAT setups. You can connect multiple routers to the existing one or daisy-chain them. Either way, each additional router can host another 253 devices.

While members of a local network hosted by one router can’t talk to those belonging to the network of another router, they all can share the Internet access from the very first router.

Keep this trick in mind in case you need to provide Internet access to a large party. Just make sure your broadband connection is fast enough for everyone.

If I combine two dual-band routers, via a network cable, would that be the same as having a tri-band router?

While this seems to make sense, unfortunately, no, it wouldn’t. In fact, you shouldn’t do that at all. That’s because the same each Wi-Fi band uses the same channels.

Dong Ngo | Dong Knows Tech It’s never a good idea to clump multiple routers, no matter how expensive, together.

More on bands and channels are available in this post, but if you can quickly imagine a Wi-Fi band as a freeway, then channels are the lanes on the road.

A dual-band Wi-Fi router consists of two distinctive sets of channels. One set belongs to the 2.4 GHz band and the other to the 5 GHz band.

Depending on your locale and hardware, the number of available channels on each band will vary. But generally, the 2.4 GHz band includes 14 channels from 1 to 14 (the last three are not available in the U.S.), and the 5 GHz has channels from 36 to 165. Again, not all of these channels are available due to one reason or another.

A tri-band router, which has an additional 5 GHz band, arranges its 5 GHz channels in two distinctive groups — lower channels and upper channels — one for each band.

The lower group belongs to the first 5 GHz band and generally consists of channels 36, 40, 44, 48, 52, 56, 60, and 64. The second 5 GHz band has the upper channels, generally including 149, 153, 157, 161, and 165.

So in a tri-band router, the two 5 GHz bands don’t duplicate each other, they work side by side. It’s like when you widen a freeway by adding more space and doubling the width of the lanes.

On the other hand, all dual-band Wi-Fi broadcasters’ 5 GHz band uses the same set of channels. As a result, putting two together is like putting one freeway right on top of another.

You can’t do that with real freeways, but that often happens in the world of radio frequencies, like when there are many routers or access points in a small area. The result is interference and congestion; there are no benefits at all.

So having multiple Wi-Fi broadcasters clumped up at a spot is something we want to avoid.

Do I need to care about Wi-Fi routers’ antennas

All Wi-Fi routers — any radio broadcasters or receivers, for that matter — have antennas. If you don’t see them, that’s because they are hidden inside or blended in with the device’s other hardware parts.

The antennas convert data signals into radio waves and vice versa. Without them, there’s no Wi-Fi. And that’s likely all you need to know about them.

Dong Ngo | Dong Knows Tech There’s no antenna sticking out of this UniFi Dream Machine, but it’s still an excellent router.

Do more antennas mean better Wi-Fi speeds?

Not necessarily. Generally, a router needs one antenna for each of its band – so a dual-band router will have two antennas. After that, the additional antennas are for extra features, such as MU-MIMO, Beamforming, and so on.

But even then, more antennas don’t necessarily mean more features. Also, the number of antennas doesn’t change the range of a router.

In other words, they just change the type of coverage but not the coverage itself. So more antennas might mean faster speed grades, though, it’s not always strictly so.

That’s because ultimately it’s how the router’s firmware handles its antennas that matters. And a Wi-Fi connection’s speed takes two; the client also needs to support the feature and speed grade of the router for the goodness to happen.

In short, there’s no need to get too hung up on the number of the little poles sticking out of our Wi-Fi box.

How to I angle the antennas for best performance?

It seems that if you set the antennas at certain angles that would affect the router’s coverage. Well, that’s kind of true technically, but in reality that doesn’t make much of a difference, if at all, in consumer-grade broadcasters.

Dong Ngo | Dong Knows Tech Feel free to angle a router’s antennas however you want.

The reason is if changing antennas’ position creates an effect, that effect would take place at the end of the router’s range. There, the signal is already too weak, the little fluctuation, therefore, results in no meaningful Wi-Fi experience.

That’s not to mention you can’t even mess with the antennas in many routers, like those with internal or non-swivel-able ones, such a the ZenWiFi AX or Archer C5400X.

So when it comes to a router’s antennas, just don’t remove or collapse them — keep them up. After that feel free to put them at any angles you’d like. What’s more important is making sure you place your Wi-Fi broadcaster well — at a high up, open place, to say the least.

How to pick the best wi-fi router for your home

Now that we’re clear on Wi-Fi routers, let’s find out how you can find exactly what you need.

Set your priorities straight

The first thing you should do is understand the fact your Wi-Fi router is by far the most important gadget in your home. Without a well-functioning one, all other fancy and expensive toys — TVs, tablets, laptops, etc. — are kind of useless.

That’s not to mention a good router can also keep you safe from hackers, malware, phishing, etc, 24 hours a day, 7 days week.

Having a good router means you will not need to tend to it regularly. So it’s a good idea to pay adequate attention upfront. Think of the router as running water or the foundation of your home.

In short, don’t be cheap, invest where it matters! Considering its important role, your Wi-Fi equipment is already really affordable.

Key to pick a Wi-Fi Router: Figuring out what you need

This is the critical part of getting the right Wi-Fi equipment.

One reader wrote: “We don’t need a super-duper one. We’re basic users. We just surf the web, stream movies, kids play games, once in while we make video calls. The usual stuff, nothing special.” Well, hello, that’s almost all there is to home networking.

The point is, you might need a better router than you think you do. That said, there are three things to consider when getting a Wi-Fi router: Coverage, speed, and features. (Note how I didn’t include the cost.)

Picking a Wi-Fi router with the right coverage: How big is your place?

The bigger your shindig, the larger Wi-Fi coverage you’ll need.

Small home

If you live in a small home of 1000 ft² (93 m²) or so, congratulations! Your situation is super easy since almost any router will be cable to blanket it. You likely won’t need to worry about where to place it, either.

Medium home

With a home twice the size, of around 2000 ft² (186 m²), things start to get complicated. If there are not many walls and the house is in a somewhat round or square shape, a single router might still do. But if there are thick walls, perhaps it’s time to think of additional hardware units.

Large home

If your home is of 3000 ft² (279 m²) or larger, a Wi-Fi system is a must. It’s now a question of which system and that depends on how fast you want the network to be.

By the way, in any home, running network cables is by far the best way to extend your network. It gives you a lot of options in terms of hardware and costs.

The shape and content of your home

Again, if a home is somewhat round or square, a single Wi-Fi broadcast, placed in the middle, can likely deliver signal to every corner. But if the place is sprawling, has an L shape or with a few floors, chances are you’ll need multiple hardware units.

Walls and large objects are problematic, too. You can read more how about how walls block Wi-Fi signals in this post, but generally, more walls and large objects equal reduced coverage, meaning you’ll need more hardware broadcasters.

By the way, it’s worth noting that, for single routers, there’s almost no difference in Wi-Fi coverage between Wi-Fi 5 and Wi-Fi 6. The two standards differentiate mostly in speeds as you can see more in this post about Wi-Fi 6. As mesh systems, however, Wi-Fi 6 is far superior.

Dong Ngo | Dong Knows Tech As a mesh system Wi-Fi 6 hardware is a lot more capable than Wi-Fi 5 counterparts.

Picking the Wi-Fi router with the right Wi-Fi speed: How fast is our Internet?

Once you’ve got the coverage down, the next item is the speed. More specifically, the speed you can afford because faster is always better.

Since most of us use Wi-Fi as a convenient way to access the Internet, it makes sense to use the broadband connection as the base requirement of this speed.

A couple of years ago, with a typical residential internet connection averaging around 30 Mbps or slower, you didn’t have to worry much about Wi-Fi rates.

Nowadays with broadband connections being available at hundreds of Mbps, or even Gigabit (1000 Mbps), finding a Wi-Fi solution capable of delivering that can deliver that can be a challenge.

Here’s the truth, you have to pick a top-notch Wi-Fi 6 router with a Wi-Fi 6 client to get the sustained Wi-Fi speed of more than 1 Gbps. The majority of existing routers and especially clients can achieve real-world Wi-Fi speeds of 800 Mbps at most. Again, that’s the total bandwidth of a Wi-Fi band.

How to figure out the Wi-Fi speed you need

So here’s the rough calculation: I’d give each person a base required speed of 30 Mbps — that’s the rate needed to stream a 4K movie smoothly. Now, assume that you have unlimited Internet bandwidth, your Wi-Fi needs to deliver 30 Mbps to everyone in the house simultaneously.

That said, if you have five people in the house (let’s assume they are always getting online at the same time,) you’ll need 150 Mbps Wi-Fi; 10 people, you now need 300 Mbps, and so on. Of course, you can adjust the base speed, making it higher or lower than 30 Mbps depending on your situation.

Now compare that needed Wi-Fi speed against a router’s real-world Wi-Fi performance — all test scores on Dong Knows Tech are real-world sustained speeds — you’ll see which router or mesh system is suitable in terms of speed. (Note: Using apps, or the Internet, to test Wi-Fi never produces the true performance of your router.)

Dong Ngo | Dong Knows Tech The Asus GT-AX11000 has a lot of useful features, including Network Protection.

Things to note in picking Wi-Fi routers’ features: What do you want from your network?

The final item is the features of Wi-Fi routers. Geeks like me probably like one with tons of features, while some home users just want something they can plug in and forget about it. The rest is somewhere in between.

Here’s the thing, you can get a feature-rich router and choose to use it with the simple default settings. But if you get a spartan one, there’s no way to add more features or settings to it when need be.

At the simplest level, though, all Wi-Fi solutions allow you to change the Wi-Fi network’s name and password. After that, the following are popular features and settings to consider. They are not all you can collectively find in Wi-Fi routers but relevant to most home’s needs.

Wi-Fi routers’ basic and necessary features and settings

These are settings that will come in handy in all home networks. Most, though not all, routers have these.

  • A web user interface: A web page that allows access to the router’s in-depth settings and features. Any routers without a web interface will be lacking in features and settings.
  • User-accessible DHCP server: All routers have the DHCP function, but only on those allowing users to access it you can customize the IP address, as well as the address pool, as mentioned above.
  • IP reservation: This allows a connected device always to get the same IP address. Some clients and applications need this to work correctly.
  • In-depth Wi-Fi customization: Users have the option to customize the router’s Wi-Fi network to their liking.
  • Guest network: A type of virtual Wi-Fi network that has access to the Internet but not your local resources.
  • Quality of Service (QoS): This is a handy feature that allows users to prioritize Internet bandwidth.

Wi-Fi routers’ advanced and desirable features

These features are generally available in high-end routers.

  • Dynamic DNS: A necessary tool for any remote access applications.
  • Port forwarding: This allows users to open specific ports for individual clients or applications. It’s a must if you run any server in your home network, including certain types of IoT devices.
  • Mesh-ready: This allows turning the router into a mesh system. The most prominent example is the AiMesh of Asus, or Synology Mesh, or TP-Link’s limited OneMesh.
  • VPN server: The ability to work as a VPN server. When coupled with Dynamic DNS, this feature is a boon for frequent travelers who want to dial home or just want to keep their device safe when using a public network.
  • Online protection: The ability to detect and filter out online threats (malware, phishing, virus, etc.). Typical examples are AiProtection (available in all Asus router), Antivirus (found in many TP-Link outer), and Armor (available in some Netgear products).
  • USB-related features: Available in routers with a USB port, these features include the ability to turn the router into a mini NAS server.
  • Game-related features: You can play the game with any router, especially one with QoS. However, some routers have even more to give pro-gamers an edge.

What you should avoid in a Wi-Fi routers

Not all features and settings are useful. The following are those I’d think twice before using.

Vendor-assisted remote management

This feature requires you to registered an account with the vendor and attach your router to that account. In return, you can manage our home network when you’re out and about.

This type of remote access is getting more and more popular with more vendors, such as TP-Link, Linksys, or Netgear, offering it as an option.

Any time you have to sign in with a vendor, that poses privacy risks. Also, you can get the same function via Dynamic DNS. That said, before you use one, make sure you trust the company’s privacy policy.

Vendor-dependent solutions

These devices are by far the worst in terms of features. They have very few of those listed above, if at all.

What makes them even less attractive is the fact that you have to have an account with the vendor, and you also have to sign in before you can control the router.

In other words, both your mobile device and your home network are connected to the vendor at all times, and you manage your home network through the vendor.

Privacy risks aside, this type of management means you do not truly own your router. When there’s no Internet connection, you can’t make changes to your home network. Or if for some reason, the vendor decides to no longer support the device, you’ll lose access to it.

Examples are those from Google (Nest Wi-Fi) and Amazon (Eero). These happen to be among the most easy-to-use, however, so it’s your call.

Best Wi-Fi solutions to consider

Below are the links to the best Wi-Fi routers and mesh systems I’ve reviewed. Check them out against what you’ve learned about, especially the performance numbers. Chances are you’ll find one that makes you happy.

Picking the best Wi-Fi router: The takeaway

There you go. I hope I have answered all possible questions about how to pick the right Wi-Fi router for your situation. Hopefully, going forward, I won’t need to make that awesome decision for anyone.

But finding that perfect Wi-Fi router is no doubt a particular task that requires a specific set of information about yourself and your home. And even then, just like in relationships, some of us might still end up with a couple of wrong choices before getting lucky. That happened to me.

One thing is for sure, though, it’s OK to take chances in picking a Wi-Fi router. Worse comes to worst; it’s comparatively painless to replace it. Take my word for it.

  1. Dong, OSPs often require their modem for TV channel guide and remote access and stop providing this function when putting the OSP device in a Mode to turn the wireless off. But Even when taking an Ethernet feed directly to homeowner’s router before passing signal on to OSP router, the OSP router will be clustered nearby the homeowner’s preferred router, providing a channel overlap situation. How if at all can this be avoided?

  2. Thank you so much, Dong. Again I have been reading to your reviews all day after your response.

    Which of the following configurations makes more sense to you in my case?

    1) Main router: Asus Blue Cave (on sale, 99USD right now)
    Access Points: A couple of TP-Link Omada AC1200 in-Wall (49USD right now)
    Placed as a star topology with the main router in the middle of the house

    2) A set of three TP-Link DecoX60 wired together

    The idea is to have an open system so we can add more hubs in the future as the house gets bigger.

    Thank you, Dong. Hope you are staying safe and healthy!

  3. Hi Dong, I have been reading your extremely detailed reviews for about 2 weeks and I am impressed with all the thoughtful insights, this is, by far, the best I have seen, thank you.

    I am in a strange situation and I think I need your help, I really hope you can…My family lives in a house (4.300ft2 (400mt2)) in a rural area in Colombia, yes your reviews are helping one of the most remotes areas in the world, so we have Satellite Internet with Hughes Net. Speeds are never higher than 30 Mbps and because of the current router there is only good internet connection in one room. I want them to have a great mesh system that allows them to have Internet in the whole house, future proofed (WiFi 6) as we are trying to add more devices in the future (cameras, TVs, etc) and I cant really decide which mesh system is the best for us. Also, the house is fully wired. You guys talk about really high speeds here but that’s not possible there so I don’t know if a mesh system of a WiFi 6 system like the Asus AX3000 or ZenWiFi, taking into account its high price, are the best option. With those slow speeds from satellite internet, are we getting the advantages of WiFi 6? I want to make a good buy for them, what would you recommend in this situation?

    Thank you again Dong!

    1. Glad you’re here, Andres.

      Wi-Fi 6 won’t make any difference in your situation (it won’t hurt, either). Also since your home is wired, you have lots of options. The most affordable is you get an Asus router (any you like) and a couple of TP-Link PoE access points (you can skip the controller). Or you can get a couple of Asus AiMesh router. Dual-band routers will do, like the Lyra Trio. Also, check out this post on how to pick your router and this one on what a mesh system is. They will help you figure things out.

  4. In your opinion, whats the best full featured valued oriented WIFI6 router? I have a few 3×3 clients (Wireless N) and want backwards compatibility so 2×2 AX3000 solutions prob aren’t favored for me.

  5. Dong, since you understand the importance of having a wired Ethernet backhaul, maybe you should do an article of the benefits of running a MoCa network. Given how cheap the solution is, I’m surprised more people don’t that in order to connect their network nodes in difficult situations. I recently did this exact thing to network the furthest rooms in the house to give them a reliable signal and low ping, and it’s made all the difference.
