If in pre-virus times you were quite happy with the quality of your home Wi-Fi, but you\u2019re not now, you are not alone. Life in lockdown has shifted online for everyone, and all at the same time. Moreover, this online existence is not spread out over the work\u2013home\u2013commuting space, but concentrated in one home, fed by a single cable. Under this increased load, problem areas have become noticeable.<\/p>\n
For example, one child is on a Zoom conference with friends learning the art of makeup, another is saving the world from killer zombies, your spouse is having a Skype language lesson in the kitchen, and the cat has occupied the bathroom (in offline mode, at least for the time being), leaving your bedroom as your office with very shaky Wi-Fi coverage. There are several ways to resolve this problem, but step 0 is understanding what exactly needs fixing.<\/p>\n
At this stage, you need to identify the specific cause of the issue. Is it really the Wi-Fi signal that\u2019s acting up? Or could it be something else, like a low connection speed from your ISP?<\/p>\n
Start with a speed checker such as Speedtest.net<\/a> or nPerf.com<\/a>. If you\u2019re getting a great data transmission rate near the router (the box that lets you use Wi-Fi), but awful in the kitchen, then, as admin guys say, the problem\u2019s on your end. In that case, it\u2019s time for another angle \u2014 analyzing your Wi-Fi network.<\/p>\n Plenty of apps that determine the signal strength of Wi-Fi networks are available for all mobile and desktop platforms. Just type \u201cwifi analyzer\u201d in any search engine or app store, and you\u2019ll see dozens of choices. Choose one that visualizes the results to help you compare readings in different parts of the home. When choosing an app, follow the usual precautions, first making sure it doesn\u2019t require access to your contacts or messages<\/a> (which it clearly doesn\u2019t need to do its job), and then scanning it with an Kaspersky Security Cloud<\/a>.<\/p>\n If you ran a Wi-Fi analysis app and discovered that in the kitchen your neighbors\u2019 networks are bursting with energy, whereas yours is on life support, that means your Wi-Fi is not doing its job. Don\u2019t despair; the problem is probably fixable.<\/p>\n The old adage \u2014 that when something is acting up you should try hitting it \u2014 is often surprisingly effective with wireless networks. We don\u2019t mean you should literally kick your router, but it may well be that the fundamental problem with your home Wi-Fi lies in the specific combination of your home\u2019s layout and where the router actually directs the radio waves.<\/p>\n So, try experimenting with the position of the router and the angle of its antennas to improve coverage. Coincidentally, this is the simplest method, requiring no extra time, money, or specialist know-how.<\/p>\n For example, if your router is located in an alcove or some kind of cabinet, especially a metal one, try moving it somewhere else. Metal is not Wi-Fi\u2019s best buddy, and neither is reinforced concrete.<\/p>\n The position of the router\u2019s antennas also makes a big difference. Google \u201crouter radiation pattern\u201d for the theory. Back at the practical level, keep in mind that in most cases the best position for the router antennas is straight up. That way your Wi-Fi router will get the best possible horizontal reach instead of carpeting the floor with valuable bandwidth.<\/p>\n Also check to see if something might be getting in the way. A refrigerator, for example, is an enemy of radio waves, but not one that can be easily shifted. On the other hand, a microwave or baby monitor \u2014 operating at 2.4 GHz and competing for the same frequency as the router uses \u2014 can be relocated much more readily.<\/p>\n If that doesn\u2019t resolve the issue, it\u2019s time to proceed to more radical measures.<\/p>\n Wi-Fi operates in a set of narrow bands, called channels, of the radio spectrum. Few channels are available, even though the number of devices that want to use them may be great. Therefore, the most popular band \u2014 2.4-GHz \u2014 can get clogged with noise from neighboring networks and other devices.<\/p>\n At each reboot or at a scheduled time, the router selects the channel that is most free from interference. It\u2019s comparable to the way a navigation system chooses the route with the fewest traffic jams.<\/p>\n Routers usually handle this task fairly well by themselves, but it\u2019s possible to intervene. For example, you can configure the router to search automatically for the least clogged channels more frequently, or even set them manually. But be careful when doing the latter; spectrum congestion is very changeable, because not only your router, but neighboring ones too are constantly and automatically switching channels.<\/p>\n Some routers additionally allow users to change the Wi-Fi signal strength. Check the router\u2019s settings to see if it\u2019s set to the maximum value, and if it isn\u2019t, feel free to crank it up.<\/p>\n\n We\u2019re moving virtually, of course. The 5-GHz band is a more respectable region of the radio spectrum with more, and wider, channels. Moreover, older router models and the cheapest new routers do not support 5 GHz, which is largely why there is less noise, and the information transfer rate can be far higher.<\/p>\n If your current router does not support the 5-GHz band, you can try upgrading to something more modern with support for the 802.11ac standard (aka Wi-Fi 5). That is no longer a luxury; inexpensive models start at about $50.<\/p>\n There\u2019s no need at this point to go for the more advanced 802.11ax (Wi-Fi 6), which is still quite expensive. Upgrading to Wi-Fi 6 is likely to have a noticeable impact only if you have a whole lot of traffic-hungry Wi-Fi devices at home.<\/p>\n Bear in mind, however, that switching to 5 GHz is not a silver bullet. The drawback of a higher frequency is that the signal decays more quickly with distance, and the effective range in larger apartments or houses can be disappointing.<\/p>\n It all depends on what the problem with your Wi-Fi network is. If the 2.4 GHz spectrum where you live is clogged up with other people\u2019s networks, and 5 GHz is available, updating really will help. But if your 2.4 GHz network isn\u2019t reaching your kitchen because of distance and an abundance of reinforced concrete walls, 5 GHz probably won\u2019t cut it, either.<\/p>\n We\u2019re so used to the convenience of Wi-Fi that we sometimes forget about good old wired Ethernet. Connecting through a cable is often the easiest and cheapest solution to seemingly hopeless Wi-Fi issues.<\/p>\n Using a wired connection can kill two virtual birds: First, it can resolve the problem in a room that stubbornly refuses to admit Wi-Fi; second, if you transfer at least some devices to a cable, the quality of the wireless connection on the remaining ones is likely to improve. Sure, you can\u2019t connect a smartphone or tablet in this way, but it\u2019s perfectly fine for a desktop computer or a smart TV.<\/p>\n If the cables stretched around your home are an eyesore and there\u2019s no easy way to hide them, try a powerline adapter that transmits the network signal through your home\u2019s electric wiring. On the downside, powerline appliances are somewhat unpredictable, and they sometimes refuse to coexist with local electric cables, that\u2019s something to keep in mind.<\/p>\n There\u2019s a whole bunch of other ways to improve the quality of your coverage. For example, you can try installing signal repeaters or replacing the router\u2019s antennas with more effective ones (you\u2019d be surprised what junk is actually inside the impressive-looking horns of a typical home router).<\/p>\n But if the word \u201cdecibel\u201d sounds scary, and network device administration is not on your list of hobbies, then it\u2019s probably best to stick to a ready-made mesh-networking kit.<\/p>\n Such kits are available from most major network equipment manufacturers. They consist of a central router and several auxiliary access points. The latter are arranged so that the signal reaches the furthest parts of the house or apartment. With a mesh system, the coverage area of your Wi-Fi network can be as large as you like\u00a0\u2014 it all depends on the number of additional access points.<\/p>\n Unlike with traditional repeaters, the system is managed centrally (auxiliary devices are usually configured automatically), which saves a lot of time and effort. If you can connect the access points to the router via Ethernet, doing so will increase both the speed and coverage area. If not, don\u2019t worry, mesh systems are nothing if not flexible.<\/p>\n Another important trait is fast, seamless roaming. That is, your video call with colleagues won\u2019t be interrupted even if family members expel you from the kitchen to somewhere covered by a different access point.<\/p>\n1.
