Each node scatters Wi-Fi throughout your house, giving you a stable connection that you don't have to worry about. It's one of the best ways to get rid of dead zones, at least. But it's not all sunshine and rainbows. As great as mesh Wi-Fi systems are, they come with some unavoidable limitations and compromises, as well as frustrating design decisions. Here are the uncomfortable truths many of us prefer not to think of. Your mesh Wi-Fi might be slower than a single router Better coverage doesn't equal better performance Mesh Wi-Fi can be super useful, especially if, like me, you've ditched the idea of wiring up your entire home. But if it's sheer speed and not coverage that you're after, I'm afraid this might come as a shock: your mesh system may not be faster at all. The reason is simple: better coverage doesn't mean better performance. Those are two separate concepts, and mesh Wi-Fi exists to help with one, not so much the other. In reality, a single powerful router can sometimes deliver faster speeds than even an expensive mesh system, but on the other hand, it has nowhere near the reach of said mesh system. It's a trade-off. The problem is especially prominent if you're connecting to one of the satellite nodes. The problem is that your device might have a solid connection to the nearest node, but that node still needs to communicate with the main router. This connection, known as backhaul, can be a bottleneck if it's wireless, which is why I prefer wired backhaul. Adding more mesh nodes can actually make things worse More coverage isn't always worth the interference If you live in a big house, you might be tempted to keep on adding mesh nodes. Makes sense; I can imagine that dead zones in various corners of the house get super annoying. But there's something that doesn't get talked about as much as it should be: adding more mesh nodes won't just eliminate every single dead zone with zero issues. It might not improve throughput or stability if you already have coverage, throwing another node into the mix might accomplish very little, or even backfire entirely. Each wireless node adds more wireless activity, and having too many of them broadcasting in overlapping areas can increase channel contention. Since Wi-Fi devices sharing a channel have to compete for airtime, this can hurt performance rather than improve it. Your devices don't always connect to the best mesh node Seamless roaming comes with some caveats On a somewhat related note, your devices may be bottlenecking themselves by picking the wrong node to connect to. This is interesting, because seamless roaming is actually a big selling point for mesh Wi-Fi. It lets you walk around your house with whatever device you're using, and it'll seamlessly switch from node to node as required. Sounds great, but there's a catch: your mesh system doesn't have the final say in which node your device ultimately connects to. The client device makes that decision, and yes, it can be pretty questionable. This can lead to what's known as a sticky client, where your device stubbornly insists on clinging to a distant node instead of moving on to something that's better and closer. Even expensive Wi-Fi 7 mesh systems can't go through every wall The newest standard doesn't change signal propagation Wi-Fi 7 is so impressive that it's probably still overkill for your households, and the latest mesh Wi-Fi systems offer absolutely ridiculous speeds. But Wi-Fi 7 still has to deal with the same physical obstacles as the previous iterations, and the impressive upgrade didn't just magically make it immune to those problems. This is especially relevant to the 6GHz band, which offers plenty of bandwidth but generally struggles more with walls and other obstacles than lower frequencies. Wi-Fi 7 offers features like 320MHz channels and MLO, which can improve performance a whole lot, but they're not going to fix signal attenuation. Thick walls stay thick, I guess. You're probably locked into one manufacturer's ecosystem Even products from the same brand might not mesh well together (pun extremely intended) One of the more frustrating things about mesh Wi-Fi is that, for better or worse, you've probably locked yourself into a whole ecosystem. You can't just grab a cheaper satellite from another manufacturer and expect it to fit with the rest of your network, even if both devices support the same Wi-Fi standard. Mesh systems often rely on proprietary technologies, so expanding your network usually means buying compatible hardware from the same manufacturer. What's even worse is that even buying from one manufacturer doesn't necessarily mean everything will be peachy. Different product lines may be incompatible with each other, too. You might be paying more to have less control Convenience can come with compromises and recurring fees Credit: Rich Hein/How-To Geek Mesh Wi-Fi is really easy to manage, most of the time, and that's just lovely. But that convenience and ease kind of stems from the fact that manufacturers take the reins to an extent, and that's not always a good thing where privacy or customization are concerned. For instance, some manufacturers don't let you manually change Wi-Fi channels or channel widths. That's a major toggle that you get no say on, as the system will handle those automatically. Then there's the issue of subscriptions. Buying an expensive mesh system still doesn't guarantee you'll never have to pay a subscription for unlocking all of its features. Such is the sad state of everything requiring a sub these days. Mesh Wi-Fi is still worth it, if you actually need it With all that said, mesh Wi-Fi continues to be the best way to fix dead zone issues in most homes, especially when you can't just run Ethernet everywhere. Just don't assume that it's perfect, because it's not, but knowing these caveats might help you avoid its biggest pitfalls.
