How to Extend WiFi to Your Garage, Backyard, or Patio
Your WiFi works great inside. Step into the garage to work on the car, pull up a playlist on the patio, or grab a signal in the backyard — and nothing. This is one of the most common WiFi problems we solve. Here's what actually works.
Why Your WiFi Dies Outside
WiFi signal doesn't travel well through walls — especially stucco, brick, concrete, or walls with metal insulation wrap. By the time your signal has passed through your home's exterior wall, it's lost 30–50% of its strength. Add distance, and the signal reaching your backyard may be too weak to maintain a stable connection.
The fix depends on how far you need coverage and whether you're willing to run a cable. Here are the main options, ranked by how well they actually work.
Run a Cat6 cable from your router or switch, through the wall or under the eave, to a weatherproof outdoor access point. Mount it under the eave, on the garage, or on a fence post. Power it via PoE from your switch or a PoE injector.
This gives you full-strength, dedicated WiFi exactly where you want it. Ubiquiti UniFi and Ruckus both make excellent weatherproof outdoor APs. The signal is rock-solid because it's not being repeated — it's a new access point on the wired backbone.
Cost: $150-350 including AP hardware, cable run, and installation. Result: Full coverage anywhere you point the AP, indefinitely.
If you already have a mesh WiFi system (Eero, Orbi, UniFi), many manufacturers offer weatherproof outdoor nodes that integrate seamlessly with your existing system. The outdoor node wirelessly backhauls to your indoor mesh — no cable required if you have good indoor coverage near the exterior wall.
The wireless backhaul does sacrifice some throughput compared to a wired connection, but for typical outdoor use (streaming music, browsing, video calls) it's more than adequate.
Cost: $150-300 for the outdoor node. Works best when the outdoor node can "see" a strong signal from an indoor node nearby.
Plug-in WiFi extenders are cheap and easy, but they have a fundamental problem: they cut your bandwidth roughly in half, because they're both receiving and re-transmitting on the same radio. The further you get from the extender, the worse it gets.
For light-duty use (checking your phone on the patio), an extender might work. For anything that requires consistent throughput — streaming, video calls, connected tools in the garage — you'll be frustrated.
Before spending anything, try moving your router to a central location on the side of your home closest to the outdoor area you need to cover. If your router is currently in an interior room or basement, moving it 20 feet toward the exterior might give you enough signal.
This costs nothing. If it works, great. If it doesn't give you reliable outdoor coverage, move to Option 1 or 2.
What About the Garage Specifically?
Garages are a special case because they typically have insulated metal walls and a metal door — both of which block WiFi effectively. For a detached garage, a wired outdoor AP is almost always the right answer. For an attached garage, try moving your router closer to the connecting wall first, then consider a wired AP inside the garage if needed.
If you want to run a cable to a detached garage, running it underground in conduit (direct-bury rated Ethernet) is the cleanest permanent solution. This also gives you a wired connection for a NAS, a desktop, or any other device you want in the garage.
