How to Extend Wi-Fi to a Garage or Outbuilding
Practical methods to extend your Wi-Fi signal to a garage, shed, workshop, or other outbuilding on your property.
Options for Extending Coverage
Getting reliable Wi-Fi to a detached garage, workshop, or shed requires more than hoping your indoor router's signal reaches. Walls, distance, and construction materials all degrade wireless signals. The right solution depends on the distance from your home, the building materials involved, and how much bandwidth you need in the outbuilding.
Mesh System Expansion
If you already use a mesh Wi-Fi system, adding a node positioned near the side of your home facing the outbuilding can extend coverage to nearby structures. For outbuildings within about 50–100 feet of the nearest node, a mesh satellite placed near a window can provide usable signal. Some mesh systems offer outdoor-rated nodes designed specifically for this purpose.
The limitation is that wireless mesh connections degrade with distance and obstacles. If the outbuilding is far from your home or has metal walls (common in workshops), wireless mesh alone may not provide adequate performance.
Outdoor Access Points
Dedicated outdoor access points are designed to bridge gaps between buildings. These weatherproof units mount on exterior walls and can transmit strong Wi-Fi signals across property distances that would overwhelm indoor equipment. Point-to-point wireless bridges can connect buildings hundreds of feet apart with minimal signal loss.
This solution is more involved to set up but provides robust, permanent coverage. Outdoor access points from networking manufacturers are designed for exactly this use case.
Running Ethernet: The Best Solution
The gold standard is running a buried or conduit-protected Ethernet cable from your home to the outbuilding, then connecting a Wi-Fi access point inside the outbuilding. This provides the same performance in your garage as in your home, with zero wireless degradation over the distance.
Use outdoor-rated, direct-burial Ethernet cable (Cat6 or better). Bury it at least six inches deep or run it through conduit. The cable can span up to 100 meters (328 feet) without a signal booster. Connect a Wi-Fi access point on the far end for full wireless coverage inside the outbuilding.

Frequently Asked Questions
What is the best way to get Wi-Fi in my garage?
Running an Ethernet cable from your home to the garage and connecting a Wi-Fi access point is the most reliable solution. If wiring is not practical, a mesh system node or outdoor access point provides wireless coverage.
Do Wi-Fi extenders work for outbuildings?
Basic Wi-Fi extenders can work for nearby structures but typically halve your bandwidth. Mesh nodes and dedicated outdoor access points provide much better performance for outbuildings.
