The best way to extend WiFi to another building depends on the distance and your budget. For buildings under 100 feet away, a powerful outdoor access point works great. For longer distances or obstacles, running ethernet cable or using a point-to-point wireless bridge gives you the most reliable connection.

I’ve helped people get WiFi to detached garages, backyard offices, pool houses, and barns. The solution that works for a shed 30 feet away won’t work for a workshop 300 feet across a field. Let me walk you through all your options so you can pick the right one.

Understanding Your Situation

Before choosing a solution, answer these questions:

• How far away is the other building? Under 100 feet vs. 100-500 feet vs. 500+ feet
• What’s between the buildings? Clear line of sight vs. trees/walls
• Can you run a cable? Buried ethernet is always the most reliable option
• What will you use it for? Basic browsing vs. video calls vs. security cameras
• Budget? Solutions range from $50 to $500+

Method	Distance	Cost	Best For
Outdoor Access Point	Up to 300 ft	$80-200	Nearby buildings, clear sight
Wireless Bridge	Up to 1+ mile	$150-400	Long distances, max speed
Ethernet Cable	Up to 300 ft	$50-200+	Best reliability, buried
Mesh WiFi Outdoor	Up to 150 ft	$200-400	Easy setup, close buildings
WiFi Extender	Up to 100 ft	$30-80	Budget option, light use

Method 1: Outdoor Access Point

This is my go-to recommendation for most people. An outdoor-rated access point mounts on the side of your house and broadcasts a strong signal that can reach buildings 100-300 feet away, depending on obstacles.

How it works: You run an ethernet cable from your router to the outdoor access point (usually mounted under the eaves). The AP broadcasts a powerful signal outdoors that can penetrate into nearby structures.

Best products: Ubiquiti UniFi AC Mesh, TP-Link EAP225-Outdoor, EnGenius ENS620EXT

Pros: Relatively affordable, good speeds, weatherproof

Cons: Requires ethernet run to the AP, range limited by obstacles

Method 2: Point-to-Point Wireless Bridge

For longer distances (500+ feet) or when you need maximum speed, a wireless bridge creates a dedicated link between two buildings. Think of it as an invisible ethernet cable through the air.

How it works: You install two directional antennas—one on each building—that point at each other. They create a private high-speed link. In the remote building, you connect a regular WiFi access point to the bridge.

Best products: Ubiquiti NanoStation or NanoBeam series, TP-Link CPE510/CPE710

Pros: Very long range (1+ mile possible), excellent speeds, reliable

Cons: Requires clear line of sight, more complex setup, two units needed

Method 3: Run Ethernet Cable

Nothing beats a wired connection for reliability. If you can run a cable between buildings—either buried underground or overhead—this gives you the best possible connection.

How it works: Run outdoor-rated ethernet cable from your router to the other building. Use direct burial cable if going underground. Add a weatherproof access point or switch in the remote building.

Key specs: Cat6 outdoor/direct burial rated, maximum 300 feet without a switch in between

Pros: Most reliable, full speed, no wireless interference

Cons: Labor-intensive, may need to dig trenches, distance limited to 300ft

Method 4: Outdoor Mesh System

Some mesh WiFi systems include outdoor-rated units that can extend your network to nearby buildings. This is the easiest solution if you’re already using mesh WiFi indoors.

Best products: Netgear Orbi Outdoor (with Orbi system), eero (weather-resistant enclosures available)

Pros: Seamless integration with existing mesh, easy setup

Cons: Limited range compared to dedicated outdoor equipment, expensive

Method 5: WiFi Extender (Budget Option)

If the other building is close (under 100 feet) and you just need basic internet for light use, a simple WiFi extender placed in a window facing the other building might work. This is the cheapest option but also the least reliable.

Pros: Cheap, easy to set up

Cons: Cuts bandwidth in half, unreliable through walls, not weatherproof

Installation Tips

• Line of sight matters: Trees, especially when wet or full of leaves, block WiFi significantly
• Height helps: Mount equipment as high as practical to clear obstacles
• Weatherproofing: Only use equipment rated for outdoor use; indoor gear will fail
• Surge protection: Outdoor ethernet runs should have surge protectors at both ends
• PoE simplifies wiring: Power over Ethernet lets you run one cable for both power and data

Frequently Asked Questions

Can I just put a router in the other building?

A router needs an internet connection. You’d need to either run ethernet to it or set it up as a wireless bridge/repeater. A dedicated access point or mesh node is usually a better choice.

Will my WiFi password be the same in both buildings?

With most solutions (mesh, access points, bridges feeding an AP), yes—you can use the same network name and password. Your devices will seamlessly connect to whichever signal is strongest.

How do I get WiFi to a building 500+ feet away?

Point-to-point wireless bridge is your best option. Products like the Ubiquiti NanoBeam can cover over a mile with clear line of sight. You’ll need one unit on each building pointing at each other.

What about powerline adapters?

Powerline adapters only work if both buildings share the same electrical panel, which separate buildings usually don’t. They’re not a viable solution for most outbuildings.

Do I need an electrician?

Most outdoor WiFi equipment uses Power over Ethernet (PoE), so you just need the ethernet cable—no electrical work. If the remote building needs a power outlet for an access point, then yes, you might need an electrician.

The Bottom Line

For most detached garages and backyard buildings, an outdoor access point ($100-200) is the sweet spot of performance and simplicity. If distance or obstacles are a challenge, step up to a wireless bridge. And if you want bulletproof reliability, bury an ethernet cable.
