How to increase the range of your WiFi

WiFi: What is the maximum range?

Especially when many people use WLAN, it depends on the maximum range. In this practical tip, we will tell you how far a WLAN can usually extend.

This is the maximum range of WiFi

  • A normal router is able to broadcast the WLAN about 50 to 100 meters (indoor).
  • However, remember that the farther you are from the router, the worse the performance of the Internet will be.
  • Various factors, such as walls, microwaves or televisions, can affect the range.
  • In addition, the range may vary from router to router.
  • In order to improve the range of WLAN, so-called WiFi repeaters can be used.
  • In order to always achieve the best range, you need to make sure that the router firmware is up to date.

How to increase the range of your WiFi

WiFi routers rarely transmit as efficiently as they can. We will show you a few tips on how to improve performance easily. 

Today you usually want to have WiFi in the entire apartment or the entire house. But under normal circumstances, the reception in each place is not enough. Usually, this is not due to the router but the installation. Also, the use of beverage cans can easily increase the transmission power of the router. You can find out from the point below which techniques can still help.

  • Position WiFi routers

  • In many cases, WLAN reception can be significantly improved with simple methods: if only a weak WLAN signal is arriving, the router may be simply in the wrong location. When setting up the router, you should pay attention to the following rules: 

    • Place the router as high as possible, such as on a cabinet. 
    • Make sure the router is free.
    • The central location of houses and apartments ensures that WLAN signals are transmitted as evenly as possible.

  • Find WiFi troublemakers

  • The router can only reach its maximum range in an empty room or outdoors. But in real life, walls, doors, and even USB 3.0 cables can slow down the WiFi signal. The biggest obstacles include items that contain water like reinforced concrete, DECT phones, microwaves, and refrigerators.

  • Install a better antenna

  • When you set up a wireless LAN in a larger building, you will soon reach the limit of the standard transmission range. Thick walls and radio wave reflection significantly limit the theoretical range of many devices to around 300 meters. If this is the case, you should consider buying a more powerful antenna. In the Internet mail order business, there are a variety of antennas to choose from, starting at about $10, and the performance gain should be between 3 to 25 dB. The 10 dB antenna increases the theoretical range of the WLAN to approximately 800 meters. The prerequisite for installing this super antenna is the socket in the SMA standard, as many modern access points and routers already provide it.

  • Measuring WiFi networks in the area

  • For all subsequent steps, it is important to know which channel your Wlan is broadcasting on, how neighbouring networks are configured, and whether the location of the router is optimal. This is why you should measure all WiFi networks in the area before actual troubleshooting. 

  • Optimize router location

  • The easiest way to optimize the WiFi range is to position the router correctly. Many people place routers next to telephone or cable jacks to save wiring with other rooms. However, this is not always optimal. In another article, we will tell you how to find the right location for your WiFi router and what to consider.

  • WLAN repeater for signal amplification

  • The WLAN repeater is a wise and cost-effective alternative. At the time of purchase, you have to expect about $30 to 100, depending on the device you want to use and whether it includes other features. For example, you can also use a WLAN repeater to extend the cable signal or connect wired devices to it.

    Before purchasing a new repeater, access point, or WLAN Ethernet bridge, please check the menu interface or manual of the existing device. These usually already support the corresponding operating mode. In addition, the existing repeater can also be used as an access point, or the access point can also be used as a repeater. If you buy a new WiFi repeater, the device must support at least dual-band and be compatible with the 802.11ac standard. Also, make sure that the device can also be used as an access point.
