How to Get Internet From Your House to Your Barn (Point-to-Point Guide)

If your barn is more than ~75 ft from your house, your existing Wi-Fi almost certainly won't reach it reliably. A mesh node extending into the barn will usually connect, then drop every time someone opens the barn door or a horse walks past the window. The fix is a dedicated wireless bridge — a pair of directional radios, one aimed at the other, doing nothing but moving internet between the two buildings.

This guide walks through a typical house-to-barn install using point-to-point (PtP) wireless: what to buy, how to mount it, how to aim it, and how to turn the ethernet cable at the barn end into good Wi-Fi inside the barn. We default to Ubiquiti / UniFi gear throughout — it's the best-supported ecosystem for this kind of install, and the single app (UniFi Network) will manage everything from the radios to the barn's access point once you're done.

Is point-to-point the right answer?

It's the right answer for most house-to-barn installs, but not all. Quick decision tree:

How point-to-point works (one minute of theory)

You mount a small radio on the house aimed at the barn, and an identical radio on the barn aimed at the house. The two radios talk to each other on a dedicated wireless link that your phones, your laptops, and your neighbor's Wi-Fi never touch. Each radio has a single ethernet port:

• House radio → ethernet → your home router (LAN port)
• Barn radio → ethernet → a Wi-Fi access point or switch inside the barn

To your network, the whole bridge behaves like a really long ethernet cable. The barn gets its IP address from your home router. Devices in the barn see your home network. Everything you already own keeps working.

The two things that kill point-to-point links:

1. Obstructions in the path. Trees with leaves, buildings, metal roofs, silage bags. You need line of sight from radio to radio.
2. Bad aim. These radios are directional. "Pointed at the other one" is not close enough — aiming within a degree or two matters for longer links.

Choosing your radios — UniFi tiers

Four UniFi options cover almost every residential barn install. Pick one.

Recommended (~$180 for the pair): NanoStation 5AC Loco 2-Pack

The most-installed PtP radio in the world. If you asked ten WISP installers what to put up between a house and barn, nine would say "NanoStation Loco." The 2-pack includes both radios, mounts, and PoE injectors — one box and you're done shopping for radios.

Step-up (~$240 for the pair): NanoBeam 5AC Gen2 2-Pack

If your link is over 500 ft, passes near trees, or you live somewhere with heavy 5 GHz Wi-Fi pollution (suburbia), the extra gain on the NanoBeam gives you a much better margin. Same configuration workflow as the NanoStation.

Budget UniFi (~$160 for the pair): LiteBeam 5AC Gen2 2-Pack

The cheapest legit UniFi PtP option. Dish form factor, 23 dBi gain, and this specific listing bundles 2 surge protectors with it — you're basically getting a complete PtP kit for what a pair of NanoStations costs alone. Older chipset than the NanoBeam, but plenty for a home internet connection with clear line of sight.

Plug-and-play (~$599 for the pair): UBB-XG 10 Gbps Bridge

The premium, zero-config option. Pre-paired out of the box — mount them, aim them, plug them in, done. No airOS, no channel hunting, no SSID setup. 10 Gbps throughput over 60 GHz. The tradeoff: shorter distance limit (~500 m) and more sensitive to rain than 5 GHz radios. If you're under 500 m with clear line of sight and you just want it to work, this is the best experience.

Alternative: TP-Link CPE510

Not UniFi, but genuinely good and cheaper per unit than the LiteBeam pair if you shop the right listing. Pharos OS is simpler than airOS for first-timers. Buy two.

Router, switch, and AP (the UniFi side of the barn)

Once ethernet gets to the barn, you need to turn it back into Wi-Fi and give the barn more than one port. Defaulting to UniFi keeps everything in a single app.

Router (house side): UniFi Cloud Gateway Ultra

Skip this section if you're happy with your existing router — the PtP radio doesn't care what router you use. But if you're building a new network or want to run the same UniFi controller that manages your APs and switches, the Cloud Gateway Ultra is the default pick.

Switch (barn side): UniFi Switch Lite 16 PoE — or Flex Mini

In the barn, the ethernet cable from the PtP radio goes into a switch. If you only need a couple of extra ports, the Flex Mini is $29 and credit-card sized.

If the barn has cameras, multiple APs, or a handful of wired devices, use a PoE switch so you don't need separate injectors for each powered device:

Barn Wi-Fi: UniFi U6 Lite

Plug this into the PoE switch (or use a PoE injector if your switch isn't PoE) and give it the same SSID and password as your house Wi-Fi — devices will roam between house and barn automatically.

If you also want Wi-Fi outside the barn — paddock, riding ring, driveway — add an outdoor AP. TP-Link EAP610-Outdoor is the best value here; managed separately from UniFi via Omada, but it'll happily coexist on the network:

PoE injector (if you don't have a PoE switch)

The non-negotiables: cable and surge protection

Install: step by step

1. Pick your mounting points

Walk outside and look at the two buildings. You want:

• A spot on the house that sees the barn. Eave, soffit, chimney, or a short mast on the roof.
• A spot on the barn that sees the house. Usually the peak of the gable facing the house, or a mast above the ridge.

Stand where each radio will mount and look toward the other building. If you can't see the other mounting point clearly with your eyes, the radios won't see it either. Tree branches that are bare in winter will be a solid obstruction in summer — plan for leaves-on.

For runs over ~500 ft, mount as high as practical. A few extra feet of height is the cheapest way to buy yourself signal margin.

2. Plan the cable runs

Each radio needs one outdoor-rated Cat6 cable running back into the building to where the PoE injector (or PoE switch) lives. Keep the outdoor run as short as you can — get inside, then run indoor-rated cable the rest of the way.

Rules of thumb:

• Ethernet has a hard limit of 328 ft (100 m) from radio to switch. Past that, you need another switch or a repeater.
• Use outdoor-rated, UV-resistant cable outdoors. Indoor cable will crack in a year of sun.
• Direct-burial (gel-filled) cable for unprotected underground runs. Otherwise, use conduit.
• Drip-loop the cable before it enters the building so water runs off instead of tracking in.

3. Install surge protectors

This is non-negotiable if you live anywhere with lightning. Mount a surge protector where the cable enters each building, and ground it to your building's ground system. The surge protector does nothing if it isn't grounded.

4. Mount and terminate

Mount the radios. Run the cable. Terminate the ends — outdoor connectors have rubber boots; get them on the cable before you crimp. Seal the RJ45 with the weatherproof boot that came with the radio.

5. Configure the link

At this point you have two radios wired up, powered, and on the network but not talking to each other. On the UBB-XG, skip this step entirely — it's pre-paired. For the NanoStation / NanoBeam / LiteBeam:

1. Plug each radio into your laptop one at a time, set an admin password, update firmware, and set a static IP on the same subnet as your home network (e.g. 192.168.1.2 and 192.168.1.3).
2. On the barn radio, set mode to Access Point with WDS enabled. Pick a 5 GHz channel with clean airtime (use the Site Survey tool — pick the quietest channel).
3. Give the barn radio an SSID and WPA2 password. These are just for the bridge itself — nobody else will ever see this SSID.
4. On the house radio, set mode to Station with WDS enabled. Point it at the barn's SSID and enter the password.
5. Verify the link comes up. You should see an RSSI of -65 dBm or better for a solid link. -50 to -60 is great. -75 or worse means aiming problems or obstructions.

(The flow is the same on TP-Link Pharos, just different menu labels.)

6. Aim

Now the fiddly part. If the radios have decent signal at this point, great. If they don't, aim:

1. Log in to the station (house) radio.
2. Open the signal meter. Most radios have an audible/visual alignment tool.
3. Loosen the mount bracket slightly so you can pan the radio.
4. Pan slowly. Watch the signal. Tighten when the reading peaks.
5. Repeat on the AP (barn) radio.

For the NanoStation Loco you usually get within 3–5 dB just by eyeballing it. For the NanoBeam and LiteBeam you will need the alignment tool — their beamwidth is narrow enough that "close enough" isn't.

7. Put the barn network on your home network

The house radio's ethernet plugs into a LAN port on your home router. The barn radio's ethernet plugs into the uplink of a small switch, or directly into the barn Wi-Fi access point.

Do not plug the house radio into your router's WAN port — you're not adding another internet connection, you're extending the LAN you already have.

8. Set up barn Wi-Fi

Plug the U6 Lite into the switch or PoE injector. Adopt it in the UniFi app. Give it the same SSID and password as your house Wi-Fi so devices roam automatically. Turn off your old mesh node in the barn — you don't need it anymore, and it will just fight with the real AP.

What good looks like

Once the install is done, you should see:

• Throughput at the barn: within 10–20% of what you get in the house (tested wired to wired).
• Ping from a barn device to a house device: single-digit milliseconds.
• Bridge signal (RSSI): -65 dBm or better, stable over days.
• No drops when the barn door opens, when cars drive past, or when it rains (light rain). Snow and heavy rain can knock 5 dB off the link — that's why you want margin.

Troubleshooting

Link comes up but speeds are terrible.
Almost always a channel / interference problem. Run a Site Survey on both radios and move to a quieter channel. 5 GHz is crowded in suburbia; try DFS channels (if your radio supports them) for a dramatic improvement.

Link is unstable in bad weather.
You're on the edge of your signal budget. Either aim better, raise one end, or upgrade from NanoStation to NanoBeam.

One radio won't get an IP / won't respond.
Nine times out of ten, PoE. Check the injector is the right voltage (24V passive for Ubiquiti airMAX — plugging in a random 48V PoE switch will brick the radio). Check pinout on your crimped ends.

Works when it's cool, drops when it's hot.
Could be a bad connector (thermal cycling on marginal crimps), or could be the radio itself if it's mounted in full sun on a black wall. Shade the radio if you can.

Can't see the other building because of trees.
You can sometimes get away with a little foliage, especially in winter. You cannot get away with a whole tree. Options: raise one or both radios above the tree line, prune, or go with a solution that doesn't need line of sight (MoCA over existing coax, or buried fiber).

Cost summary

Add ~$130 if you also want outdoor Wi-Fi around the barn (EAP610 Outdoor).

Frequently asked questions

Will this work through the side of my metal-roofed barn?
Signal has to get to the radio, not through the building. Mount the barn radio on the outside of the barn, facing the house. The ethernet cable goes through the wall.

How long does a PtP install last?
Ubiquiti radios in normal weather will run 5–8 years. The two weak points are the cable terminations (UV, weather, chewing rodents) and the surge protector after a nearby strike. Both are cheap to replace.

Can I have a third building?
Yes. Either add a second point-to-point link from the house to building C (two more radios), or switch to a point-to-multipoint setup where the house radio is a sector antenna and the outbuildings each have a station radio aimed at it. Point-to-multipoint is a different article.

Do I need a static IP from my ISP?
No. Point-to-point is just a LAN extension. Your ISP doesn't know or care that you've added a wireless bridge to your own network.
