How To Get Wifi In A Detached Garage: A Beginner's Guide

Why WiFi in a Detached Garage is Essential

Having WiFi in your detached garage can greatly enhance its functionality and convenience. It allows you to connect your devices, stream music or videos, and even work remotely. Whether you want to create a comfortable workspace, set up a smart garage system, or simply enjoy entertainment while tinkering with your projects, having a strong and reliable WiFi connection is a must.

1. Assess Your WiFi Signal Strength

The first step to getting WiFi in your detached garage is to assess the strength of your existing WiFi signal from your main router. This will help you determine whether you need to extend your current network or set up a new network specifically for your garage.

Checking Signal Strength

Walk around your garage and use your smartphone or a WiFi analyzer app to check the signal strength. If you have a weak or non-existent signal, you’ll need to take further steps to improve your WiFi coverage.

2. Extend Your WiFi Network

If your main router’s signal reaches your garage but is weak, you can extend your WiFi network using a wireless range extender or a powerline adapter. These devices work by boosting the existing signal and extending its coverage.

Wireless Range Extender

A wireless range extender captures the existing WiFi signal and rebroadcasts it, effectively extending its range. Place the range extender in a location that receives a strong signal from your main router, ideally halfway between your router and garage.

Powerline Adapter

If running a long Ethernet cable from your router to your garage is not feasible, a powerline adapter can be a great alternative. It uses your existing electrical wiring to transmit the internet signal from your router to the garage. Simply plug one adapter into an outlet near your router and connect it to the router using an Ethernet cable. Then, plug the second adapter into an outlet in your garage, and you’ll have a wired connection for your WiFi router.

3. Set Up a Dedicated Network

If extending your existing network is not sufficient or you want to avoid potential interference, setting up a dedicated network for your garage is the way to go. This involves adding a separate router or access point in your garage.

Adding a Router

Purchase a router that supports wireless bridge or access point mode. Connect the new router to your main router using an Ethernet cable. Configure the new router to use a different network name (SSID) and password than your main network. This way, you’ll have a separate network specifically for your garage.

Using an Access Point

If you already have a spare router, you can repurpose it as an access point. Connect the spare router to your main router using an Ethernet cable. Disable the DHCP server on the spare router and configure it to use the same network name (SSID) and password as your main network. This will allow your devices to seamlessly connect to the same network whether you’re in your house or garage.

4. Improve WiFi Signal Strength

If you’re still experiencing weak WiFi signal in your garage, there are a few additional steps you can take to improve the signal strength.

Position Your Router Strategically

Ensure your main router is placed in a central location within your house. Avoid placing it near large appliances or behind walls that can obstruct the signal.

Upgrade Your Router

If your router is old or doesn’t provide sufficient coverage, consider upgrading to a newer model with better range and performance.

Use External Antennas

Some routers allow you to attach external antennas to improve signal strength and coverage. Check if your router supports this feature and consider investing in high-gain antennas.

Install a WiFi Mesh System

A WiFi mesh system consists of multiple access points strategically placed throughout your home and garage, creating a network that blankets the entire area with a strong WiFi signal. This can be a more expensive option but provides excellent coverage.

5. Secure Your Garage Network

Finally, don’t forget to secure your garage network to prevent unauthorized access. Use a strong and unique password for your WiFi network, enable encryption (WPA2 or higher), and consider enabling guest network access if needed.


Getting WiFi in your detached garage is feasible with the right equipment and setup. Whether you choose to extend your existing network or create a dedicated one, ensure that you have a strong and reliable WiFi connection to enhance your garage’s functionality and make the most out of your time spent there.
