Mesh Wi-Fi is the most expensive way to fix a dead zone, and one wired access point beats it on almost everything

Wi-Fi isn't a perfect medium, and even today, the average user deals with poor coverage in the form of "dead zones." Either due to poor ISP hardware or a complex home layout, your router's signal can lose strength in areas located furthest from it. Range extenders are a horrible way to patch this gap, so most people turn to mesh Wi-Fi. Using a central node and one or more satellite nodes, a mesh network attempts to envelop your home in a blanket of seamless coverage. While this idea has merit, it is often overkill when you need to fix a single dead zone in your house. You can instead hardwire an access point to your router and position it strategically to fix the gap for a fraction of the cost of an expensive mesh network. Mesh Wi-Fi is often the default answer to subpar coverage But it doesn't have to be Mesh Wi-Fi isn't a fancy range extender. While extenders rebroadcast your router's signal to create a new network to amplify coverage, a mesh network creates a single, intelligent unified network. It automatically routes traffic from your device to the main router via the best possible node, eliminating the need for manual SSID selection. All the mesh nodes can talk to each other, unlike range extenders that only communicate to the main router. Mesh Wi-Fi is ideal for large homes where the square footage is too much for a single router to cover or the topology of the house results in too many obstructions and, hence, multiple dead zones. The upfront cost is recouped over time as the intelligent network eliminates range issues in your network. However, mesh Wi-Fi isn't free from latency issues, especially when it keeps shuttling your device between nodes endlessly. Plus, wireless backhaul, which most people default to, reduces the bandwidth available for your devices. A single dead zone doesn't need an expensive mesh network Wiring an access point to your router is enough Fixing an isolated dead zone in your house doesn't actually need a full-fledged mesh network. You can instead use a more precise fix to spread coverage to that spot or room. A wired access point can provide a dedicated line to your router, broadcasting a full-strength signal from that spot to completely cover the dead zone. You don't even need to buy a $100 access point to achieve this; you can easily repurpose an old router into a wired access point. Alternatively, you can even buy an inexpensive router online. Connect its Gigabit port to your router, disable DHCP on it, flash a custom firmware like OpenWrt, and install it close to the dead zone in the house. Using the same SSID on both your main router and the wired AP will allow seamless roaming for your devices. A wired access point provides lower latency and higher reliability than a mesh node using wireless backhaul. While it's possible to use wired backhaul with your mesh node, it's still a costly solution to fix a minor coverage problem. Routing a fresh Cat6 cable isn't always possible It needs time, effort, and money Credit: Source: Asus A significant challenge associated with this "cheap" fix is cleanly running a Cat6 cable to your wired access point. It takes time and money to do it, especially if you hire a technician. The labor cost might be way more than the cost of a mesh network you're trying to avoid. Unless you're willing to do it yourself, there are alternatives to routing an Ethernet connection to your dead zone. The first, and most effective one, is to check your walls for existing coaxial cable (used for old TVs). These can be used with two MoCA adapters to convert Ethernet signals into radio frequencies, and back to Ethernet on the other end. Most MoCA adapters support speeds up to 2.5 Gbps, so most people can use their multi-gig plans at full capacity. The other, less ideal fix is to use powerline adapters to use your existing electrical wiring to carry network signals to the dead zone. Powerline is significantly slower than MoCA, only supporting up to 100–200 Mbps signals, since they're prone to electrical interference. They should be your last resort when routing Ethernet signals without running a Cat6 cable. You could consider a mesh system with a single satellite node (for now) if the investment isn't too high. You can extend your mesh network with more nodes in the future if you move to a larger house. It'll still be more expensive than repurposing a cheap router into an access point, but if the price difference isn't huge, it can be simpler for most people. You don't always need mesh Wi-Fi to improve coverage Most homes have one or two dead zones that their router can't reliably cover. Using an expensive mesh network to solve this problem isn't ideal, since you're still relying on wireless signals. Using a cheap router as a wired access point will give you a more reliable connection. You can use MoCA or powerline adapters if routing Cat6 cables through walls isn't feasible in your house.

Using this network, you can extend the range of your WiFi considerably even in a large area.
