NanoStation 5AC loco

Initial Setup – 5AC Loco
5AC Loco units are set up like M5s but have a newer interface.

1. Powering the Device:

   • Use the included PoE injector.

   • Connect the PoE port on the injector to the LAN port on the Ubiquiti device.

   • Connect the LAN port on the injector to your network or directly to your computer for setup.

2. Accessing the Device:

   • By default, the device uses DHCP, so use Advanced IP Scanner to find its IP on your network.

   • If it's not connected to a network, it will fall back to 192.168.1.20.

3. First Time Login:

   • Open the IP address in a web browser.

   • On the first screen, select your country (Ireland), choose your language, and accept the Terms & Conditions to continue.

4. Troubleshooting Access:

   • If you can’t access the setup page, make sure your computer is on the same IP range as the device.

   • If you're unsure how to do this, refer to our guide on changing your IP on Windows.

Set a Username and Password
If you forget the password, the only way to fix it is to factory reset the device — this will erase all settings.

We recommend using:
Username: ubnt
Password: Admin1234 

Setup Guide for Nano Devices - Access Point

1. Log In and Go to Wireless Settings
   Click the Wireless icon (second icon from the top on the left side).

2. Set Up the Access Point (AP)

   • Turn Access Point mode ON.

   • If you're setting up a simple 1-to-1 link (one Station to one AP), turn PTP Mode ON.

   • If you have multiple Stations connecting to the AP, leave PTP Mode OFF (this is called Multipoint).

3. Channel Width
   Leave the Channel Width at the default 40 MHz – it works well for most locations.

4. Control Frequency (Optional)
   If the site requires a specific frequency range, enable Control Frequency and set the range. The Nano will search within that range to find its pair.

5. Set the SSID
   Change the SSID of the AP to something easy to recognise, like "ubntAP".
   This makes it easier to find when connecting from the Station.

6. Change the Password
   Under Wireless Security, change the password that will be used to connect the station.
   We recommend using Admin1234 for now (you can change it later if needed).

7. Apply Settings
   After making all changes, click Save Changes to save and activate the settings.

Setup Guide for Nano Devices – Station

1. Log In and Go to Wireless Settings
   Click the Wireless icon (second icon from the top on the left side).

2. Set Up the Station

   • Turn Access Point mode OFF (this puts the device into Station Mode).

   • If connecting to a single AP in a 1-to-1 setup, turn PTP Mode ON.

   • If connecting to an AP used by multiple stations, leave PTP Mode OFF.

3. Channel Width
   Leave the Channel Width at the default 40 MHz.

4. Control Frequency (Optional)
   Enable Control Frequency only if you're targeting a specific frequency range to match the AP.

5. Search and Lock to AP

   • Click “Select” under the SSID box.

   • Find and select the SSID of the AP (e.g. ubntAP).

   • At the bottom of the window, click “Lock to AP”.

6. Change the Password
   Under Wireless Security, change the password to the same password used on AP in set up above.
   We recommend using Admin1234 for now (you can change it later if needed).

7. Apply Settings
   After making all changes, click Save Changes to save and activate the settings.
   
   

IP Address Setup Options

There are two ways to set the IP address on Ubiquiti devices:

1. DHCP (Dynamic IP)

   • The device gets its IP automatically from the network.

   • You can also set a Fallback IP — if it can’t get an IP from the network, it will default to this address (e.g. 192.168.1.20).
     
     

2. Static IP

   • You manually assign a fixed IP address.

   • The device will always try to use this IP and will be reachable at that address.

   • Make sure the IP and Gateway are in the correct range for your network.

Final Check: Signal Strength (for 5AC Devices)

Once the 5AC devices are paired and linked, verify the connection quality using the Link view in the airOS 8 interface:

Where to look:

• Go to the Main Dashboard and select the Link tab.

• Both the Local Device and Remote Device signal levels will be shown side-by-side.

What to check:

Example from screenshot:

• Signal: –37 dBm 

• Noise Floor: –90 dBm 

• RX Rate: 8X 

• Throughput Capacity: 650 Mbps+
  
  

If you're seeing poor signal or rate (e.g. 2X or signal worse than –65 dBm):

• Improve antenna alignment and line of sight.

• Reduce interference or obstructions between devices.

• Avoid placing units too close during indoor setup — 1–2 meters is ideal.

Troubleshooting Tips

1. Finding the IP Address
   5AC Locos use DHCP by default, so finding the IP can be tricky.
   If needed, try the fallback IP: 192.168.1.20.
   
   

2. Keep Some Distance
   When pairing, leave 1–2 meters between the devices.
   If they’re too close, they might not connect properly.
   
   

3. Try Rebooting
   If something isn’t working, a simple reboot of both devices often fixes the issue.
