Sign in to your How-To Geek account If you're constantly dealing with the frustration of weak Wi-Fi and spotty coverage at home, it's only a matter of time before you start eyeing those advanced and pricey mesh systems. To be fair, they absolutely have a place in large homes where a single router struggles to reach every corner. However, more often than not, people end up overspending on expensive mesh hardware when the real problem comes down to an imperfect setup. Before you go out and spend money on a mesh system, it's worth trying these easy fixes that can noticeably improve your Wi-Fi for free. Keep your router unobstructed and away from other devices Furniture and electronics can choke your signal Placing your router next to a dense object is practically a death sentence for your Wi-Fi. Wi-Fi signals are a type of high-frequency radio wave, and they radiate outward from your router in all directions. While they can pass through objects, the signal becomes weaker as it does. Thin and porous materials like drywall and wood let signals pass more easily than solid ones like concrete and metal, but that doesn't mean you can place your router inside a cupboard and expect good signal strength. If you block the signal right at the source, i.e., the router, it will have a hard time reaching your devices, especially when they're in another room. The higher-bandwidth 5GHz and 6GHz bands will especially struggle to penetrate objects, effectively leaving you with just the lower-bandwidth 2.4GHz signal for all your devices. Similarly, home appliances can block the signal physically, but they can also introduce interference. This is a much bigger problem when the router is sitting close to these devices because the signal gets blocked by devices that introduce electromagnetic interference or rely on the same frequency band as your router. Microwaves are the biggest offender, but Bluetooth devices, cordless phones, and baby monitors all rely on the 2.4GHz band. Move the router away from larger electronics like TVs and consoles as well, as they can create interference—I noticed an instant signal improvement when I recently moved my router away from my kitchen TV. Quiz8 Questions · Test Your KnowledgeMesh WiFi networks: history, tech, futureTrivia challengeFrom military roots to whole-home coverage — how well do you really know mesh WiFi?HistoryTechnologyBrandsFuture TechFun FactsBeginThe concept of mesh networking was originally developed for use in which field before it reached consumer homes?AHospital patient monitoring systemsBMilitary and battlefield communicationsCSatellite television broadcastingDEarly cable TV infrastructureCorrect! Mesh networking grew out of military research, particularly DARPA-funded projects aimed at creating self-healing, decentralized communications that could survive partial network destruction. The idea was that if one node went down, traffic would reroute automatically — a very useful feature on a battlefield.Not quite. Mesh networking has its roots in military and DARPA-funded research, designed to create resilient, self-healing communications networks for battlefield use. The decentralized nature meant no single point of failure — a concept that later translated beautifully to home WiFi coverage.ContinueWhat is the primary technical difference between a traditional WiFi extender and a true mesh WiFi system?AMesh systems use a dedicated backhaul channel to communicate between nodesBMesh systems always require ethernet cables between every nodeCWiFi extenders operate on the 6 GHz band while mesh uses 5 GHz onlyDMesh systems broadcast multiple separate SSIDs for each nodeSpot on! True mesh systems use a dedicated backhaul — often a separate radio band — exclusively for node-to-node communication. This keeps the bandwidth used by your devices separate from the bandwidth used to pass data between nodes, resulting in far less congestion and much better performance than a traditional extender.Not quite. The key differentiator is that true mesh systems use a dedicated backhaul channel between nodes, keeping device traffic and inter-node traffic separate. Traditional extenders reuse the same band for both, effectively halving available bandwidth — which is why they often disappoint in practice.ContinueWhich company is widely credited with popularizing consumer mesh WiFi when it launched its first product in 2015?ANetgearBTP-LinkCEeroDGoogleCorrect! Eero launched in 2015 as one of the first consumer-focused mesh WiFi systems and essentially kicked off the home mesh revolution. Its simple app-based setup and attractive hardware stood out in a market dominated by ugly router boxes covered in antennas. Amazon later acquired Eero in 2019.Not quite — Eero gets the credit here. Founded in 2014 and launched to consumers in 2015, Eero was a pioneer in making mesh WiFi accessible and appealing to everyday users. Its clean design and smartphone-based setup felt revolutionary compared to traditional router management interfaces.ContinueA mesh WiFi network behaves similarly to which surprisingly ancient human communication system?AThe Pony Express relay systemBRoman signal fire chains along Hadrian's WallCGossip spreading through a village — each person tells the nextDThe semaphore flag relay towers of Napoleonic FranceGreat analogy — and you got it! Mesh networking mimics the way gossip spreads: each node receives information and passes it along to the nearest neighbor, with multiple paths available if one route is blocked. Computer scientists actually call one mesh routing method 'gossip protocol' for exactly this reason.Fun guess, but the best analogy is gossip spreading through a village. In mesh networking, data hops from node to node along the best available path — just like a rumor finding its way through a crowd. Computer scientists even formally named one routing approach 'gossip protocol' in honor of this similarity.ContinueWiFi 6E and WiFi 7 mesh systems introduced support for which frequency band that older mesh hardware cannot use?A900 MHzB3.6 GHzC6 GHzD10 GHzCorrect! WiFi 6E opened up the 6 GHz band for consumer use, giving mesh systems a much less congested slice of spectrum to use — especially valuable as a clean, fast backhaul channel. WiFi 7 expands on this further with multi-link operation, letting devices use multiple bands simultaneously.The answer is 6 GHz. WiFi 6E was a significant leap because it unlocked the 6 GHz band — a largely empty, high-capacity range of spectrum that dramatically reduces interference, especially in apartment buildings packed with competing networks. Mesh systems use it as a super-clean backhaul highway.ContinueBefore dedicated mesh systems existed, some creative users built their own mesh-like home networks using open-source firmware called what?AOpenWrtBFreeNASCpfSenseDDD-WRTWell done! DD-WRT was the go-to open-source router firmware for enthusiasts who wanted to squeeze extra performance and features out of consumer routers — including running multiple routers in coordinated configurations that resembled mesh behavior. It's still actively developed today and has a devoted following.Not quite — the answer is DD-WRT. This legendary open-source firmware let tech-savvy users replace the factory software on routers from brands like Linksys and Netgear, unlocking advanced features including multi-router setups that approximated mesh networking years before polished consumer mesh products existed.ContinueWhich emerging concept would take mesh networking beyond the home and create a massive, self-organizing internet built from billions of everyday devices?AEdge computing clustersBThe Wireless Web (WWW 2.0)CDecentralized People-Powered Internet (DPPI)DThe Internet of Things (IoT) meshExactly right! The Internet of Things vision includes smart devices — thermostats, lights, sensors, appliances — forming spontaneous mesh networks with each other, passing data along without relying on a central router or ISP infrastructure. Standards like Thread and Matter are already pushing this concept into real homes today.The answer is the IoT mesh. The Internet of Things roadmap envisions billions of smart devices forming organic, self-organizing mesh networks — communicating peer-to-peer without needing a traditional router as a middleman. Protocols like Thread (used in Matter-compatible smart home devices) are making this a reality right now.ContinueWhat quirky real-world project demonstrated mesh networking by connecting an entire island community with a DIY WiFi mesh built mostly from recycled hardware?AThe Faroe Islands Fiber Mesh ProjectBGuifi.net in Catalonia, SpainCProject Loon in New ZealandDThe Aloha Network in HawaiiCorrect! Guifi.net, launched in rural Catalonia in the early 2000s, grew into one of the world's largest community-owned mesh networks with tens of thousands of nodes. It was built by volunteers using cheap or recycled hardware to bring internet access to areas ignored by commercial ISPs — a remarkable grassroots achievement still operating today.The answer is Guifi.net. This incredible volunteer-built mesh network in Catalonia, Spain, started in the early 2000s and eventually grew to over 35,000 active nodes, making it one of the largest community mesh networks on the planet. It proved that determined communities could build their own internet infrastructure without relying on big telecoms.See My ScoreChallenge CompleteYour Score/ 8Thanks for playing!Try Again Elevate your router and place it in the center of your home Your router shouldn’t live on the floor Credit: Rich Hein/How-To Geek Placing your router in an open area away from other objects is only one part of the battle—if you want the best coverage, you should place it higher up in the room. Putting it on the floor or a very low surface limits its coverage, as much of the signal gets absorbed or blocked at ground level. Placing the router at a height between 5 and 7 feet off the ground in a one-story house, as close to the center of your house as possible, will usually give you the best coverage. The Wi-Fi signal can spread more evenly in all directions and has a better chance of reaching adjacent rooms. While looking for an elevated surface to place the router on, avoid placing it right next to outside walls, especially if you don't need coverage outdoors. A wall-mounted shelf can help with elevation and hiding the cables, but keep some space between the router and the wall. Adjust your antennas to shape coverage Small tweaks can noticeably extend your signal Credit: Ismar Hrnjicevic / How-To Geek It’s easy to dismiss a router’s antennas as just a small, functional part of the design, but there’s a reason most modern routers let you adjust them—their angle has a real impact on how the signal is distributed. Antennas don’t broadcast equally in all directions. Instead, the signal typically spreads in a donut-like shape. When an antenna is positioned straight up at a 90-degree angle, that signal extends outward horizontally, which is great for covering a single floor. But homes are three-dimensional, so vertical coverage matters too. Angling the antennas can redistribute the signal to provide a better balance between horizontal and vertical reach. In any case, it’s worth experimenting. Test your signal in the hardest-to-reach spots before and after adjusting to see what works best in your space. TP-Link Archer AX55 Wi-Fi Bands Dual-Band Supported standards 802.11ac, 802.11ax, 802.11b, 802.11g, 802.11n Want a cheap and reliable Wi-Fi 6 router with adjustable antennas? The TP-Link Archer AX55 is an excellent choice. Run Ethernet to every device you can Wired connections free up wireless bandwidth Credit: Bertel King / How-To Geek Sometimes, the best way to improve your Wi-Fi performance and reliability is to do the exact opposite—switch back to a wired connection for every device you can. Your desktop PC, smart TV, console, and NAS (if you have one) are the obvious candidates. If your laptop has an Ethernet port, you can plug it in too, or use a simple USB-C to Gigabit Ethernet adapter. Doing this reduces congestion on your Wi-Fi network, allowing devices that rely on wireless, like phones and tablets, to make better use of it. On top of that, the devices you’ve moved to wired will also benefit from a faster and more stable connection.

And like any computer, routers are prone to random issues when they run for long periods, which can usually be fixed with a reboot. At the very least, you're clearing the cache and memory and giving the router a chance to select a channel that none of your neighbors are using. Fortunately, even the cheap Wi-Fi routers often now support scheduled reboots. It’s usually buried somewhere in the advanced options, which you can access through your router’s app or by typing your router’s IP address (often 192.168.1.1 or 192.168.0.1) into your browser and logging in. Once you find it, I recommend scheduling the reboot sometime in the dead of night, once a week—such as Tuesday at 4:30 am. If your router doesn't have the option, you can use a smart plug to create a schedule instead. If these fixes aren’t enough, then it’s time to consider mesh The right router setup can go a long way in improving your Wi-Fi signal. That said, some homes have unique layouts with multiple thick walls that create dead zones a single router can’t fully cover. If you’re still experiencing poor Wi-Fi strength after going through these tips, it may be time to switch to a mesh system.
