The reality is that Wi-Fi speeds achieved in ideal radio conditions drop substantially in poorer conditions. With claims of massive speeds (such as 11,000 Mbps from the latest products), it’s no wonder that so many broadband users are disappointed when speed tests reveals speeds of only 1% or less of these claims. We cannot think of another area where performance claims exceed the reality experienced by broadband users by such an extent. If you want a laugh, pop over and have a read of the websites of most Wi-Fi equipment manufacturers. However, with modest planning and measurement, you can dramatically improve your Wi-Fi network and maximise speeds where you want them.ĭon’t be fooled by Wi-Fi equipment manufacturers’ claims as the reality is Wi-Fi is often the weak link in the broadband chain ![]() Furthermore, the use of a single Wi-Fi router increases the chance of ‘not-spots’ – locations where absolutely no Wi-Fi service is possible. In a typical residential property, we show, using real-life measurements, that these targets are perfectly achievable, but generally only with multiple Wi-Fi Access Points rather than a single Wi-Fi router. Typical answers are along the lines of “SNRs of 24-40 dB are considered good” but they do not explain the compromise in speeds you are potentially making due to the adaptive modulation and coding built into Wi-Fi technology. For the best Wi-Fi speeds, signal strengths of -50 dBm or greater or signal-to-noise ratios of 41 dB or greater are necessary. Avoid setting up your wireless router in rooms with lots of tall objects.“What is a good signal level or signal-to-noise ratio (SNR) for Wi-Fi” is one of the most common questions in online forums. Tall furniture and appliances can block signals, especially when leaning against thick walls.If your walls are impeding the Wi-Fi signal, open the door to the room where your router is, and place the router is as close to it as possible. You may also run into trouble if your walls contain metal ducts, studs, and pipes. ![]() Thicker walls, such as those made of brick, concrete, or stone, seriously impact signal strength.If you can't move the router away from glass, try covering the glass with a curtain or cloth. Glass from mirrors and windows reflect Wi-Fi signals back around the room.If the router is on the floor or on a low table, you'll be wasting much of the router's signal 360-degree range. X Expert Source Luigi OppidoĬomputer & Tech Specialist Expert Interview. Place the router high up, such as on a wall mount or high shelf.If that's not possible, you can still improve reception by minimizing some barriers: To maintain the most reliable internet connection, make sure your computer has line-of-sight access to the router. A Wi-Fi signal can usually travel about 1000 feet, but every wall drops that by about 100 feet. Remove physical obstructions between your computer and the router.
