To check the WiFi signal strength effectively, there are several tools and techniques you can use that’ll help diagnose and address issues like buffering on Netflix and choppy video calls. Here’s a rundown:

  1. Router’s Admin Panel:
    Most modern routers come with a built-in admin panel you can access via a web browser. Type your router’s IP address (often something like 192.168.1.1) into your browser’s address bar and log in with your credentials. In the panel, there should be a section for WiFi status or signal strength. This is more technical and might require some digging, but it’ll give you specifics on signal quality.

  2. Built-in Tools on Your Device:

    • Windows:
      You can check WiFi signal strength right from your desktop. Click on the WiFi icon in the taskbar. The more bars you see, the stronger the signal.
    • MacOS:
      Hold down the Option key and click the WiFi icon in the menu bar. This will show you detailed information on your WiFi connection, including signal strength (measured in dBm). The closer the number is to 0, the better. For example, -30 is a strong signal, while -90 is very weak.
    • Smartphones/Tablets:
      Both Android and iOS have built-in indicators. On Android, go to Settings > WiFi and look at the signal strength. iOS is similar – just open Settings > WiFi.

  3. WiFi Analyzer Apps:
    There are numerous apps designed to assess and diagnose WiFi signal strength:

    • WiFi Analyzer (Android):
      This app provides a graphical view of your network’s signal strength over time, helping you understand changes in connection quality.
    • NetSpot:
      If you’re looking for a more comprehensive tool, consider NetSpot. It’s available for Mac and Windows and allows you to do a complete site survey, offering detailed insights into your WiFi signal strength throughout your home or office. You can download it from their official site – https://www.netspotapp.com.

  4. Using Command Line:

    • Windows:
      Open Command Prompt and type netsh wlan show interfaces. Look for the ‘Signal’ field which will show the signal strength as a percentage.
    • MacOS and Linux:
      You can open the Terminal and type iwconfig. This will show you various details including signal level.

  5. Hardware Tools:
    For a more precise assessment, you could use a WiFi signal meter. These are handheld devices that can give you a detailed reading of signal strength. They’re more commonly used by professionals but can be useful for a DIY approach.

  6. Optimizing Signal Strength:
    Once you’ve determined your signal strength, here are a few tips to boost it:

    • Router Placement:
      Place your router in a central location, elevate it off the floor, and ensure it’s not obstructed by walls or furniture.
    • Channel Switching:
      If you’re in a densely populated area, changing your WiFi channel can reduce interference. This can usually be done in the router’s admin panel.
    • Range Extenders and Mesh Networks:
      If certain areas of your home are persistently weak, consider a range extender or a mesh network to improve coverage.

Remember, the type of building materials and the layout of your home can significantly affect WiFi signal strength. Metal, concrete, and even some types of glass can weaken the signal. By using tools like NetSpot, you can create a visual heatmap of your signal strength and strategically place your router or extenders for optimal performance.
