How to Extend Wifi to Detached Garage


A detached garage is a separate structure from your home that provides a convenient space for various purposes such as a workshop, hobby room, or storage space. If your garage is separate or far from your house area, it may cause for Wi-Fi weak signal. Also, this can be frustrating when you need to work on a project that requires an internet connection. So, all you need to extend your Wi-Fi signal as soon as possible. There are many ways to extend your Wi-Fi connection. After some research, I found some useful and effective methods that will help you to be your problem fixed.

How Do Wi-Fi Signals Work?

Wi-Fi signals work by transmitting data using radio waves in the unlicensed 2.4GHz and 5GHz frequency bands. The Wi-Fi router uses an antenna to broadcast a signal, which is picked up by a device’s Wi-Fi adapter. The data is then decoded and can be used to connect to the internet or other network resources. Wi-Fi signals can pass through walls and other solid objects, but their range can be limited by physical barriers and interference from other electronic devices.

Why and when Wi-Fi signal is Interrupted?

How to Increase WiFi Range in House
Your Wi-Fi signals can be interrupted or degraded due to several reasons. Here we noted 06 main and common reasons that may you have.
  1. Physical barriers: Walls, ceilings, furniture, and other solid objects can obstruct the Wi-Fi signal and weaken its strength.
  2. Interference from other devices: Electronic devices such as microwaves, cordless phones, and baby monitors can interfere with the Wi-Fi signal and cause disruptions.
  3. Distance from the router: The strength of the Wi-Fi signal decreases as the distance from the router increases.
  4. Overlapping frequency channels: If multiple Wi-Fi routers are using the same or overlapping frequency channels, they can interfere with each other and cause signal degradation.
  5. Obstructions caused by people: People can also block the Wi-Fi signal as they move around the house, especially if they are between the router and the device trying to connect.
  6. Outdated hardware or software: Old routers or devices with outdated software can also cause signal problems, especially if they do not support the latest Wi-Fi standards.

Note: If your Wi-Fi signal strength is low and you want to fix it, you have to understand what is the main reason for this.  Then you can take steps to improve the quality and reliability of your Wi-Fi network by fixing that issue.

Understanding the Wi-Fi Signal Strength

Before we dive into the methods to extend Wi-Fi to your detached garage, you have to understand the Wi-Fi signal strength. Wi-Fi signal strength is measured in decibels (dBm). The higher the number, the stronger the Wi-Fi signal. A strong Wi-Fi signal ranges from -30 to -50 dBm, while a weak signal is below -70 dBm.

Knowing your Wi-Fi signal strength is important to determine the best method to extend Wi-Fi to your detached garage. You can use a Wi-Fi analyzer app to determine the Wi-Fi signal strength in your garage. Or you can manually check the signal on your device. As the process varies for different devices, I mentioned 04 individual processes for each operating system below.

  1. On Windows: Right-click the Wi-Fi icon in the system tray, click “Open Network and Sharing Center”, click “Wi-Fi” (it may also say the name of your Wi-Fi network), then look under “Signal strength“.
  2. On Mac: Click the Wi-Fi icon in the menu bar, hold the Option key, then click “Open Wireless Diagnostics“. From there, select “Window” and then “Scan“. The signal strength of your Wi-Fi network will be displayed.
  3. On Android: Go to “Settings” -> “Network & Internet” -> “Wi-Fi” -> tap and hold on the Wi-Fi network you’re connected to -> “Network details“. The signal strength will be displayed in the “Signal” field.
  4. On iPhone: Go to “Settings” -> “Wi-Fi” -> tap the “i” icon next to the Wi-Fi network you’re connected to. The signal strength will be displayed in the “RSSI” field. For details, you can read this article:
