Ubiquiti airMAX – How to Configure a Long-range WiFi Client

Alex Miller says:

Achieving Wireless Connectivity in locations such as Campsites and Yacht Marinas has become a necessity and we are excited by Ubiquiti’s ability to fulfill this need.

Scenario – Boat Connectivity

Front of the Boat Deck

Ubiquiti Bullet M2 Titanium 2.4GHz Zero-Variable Outdoor Radio
Ubiquiti Omni AirMax MiMo Antenna 2.4GHz 10dBi

Hull of the Boat

To complete the installation a Cat5 (Toughcable Carrier) runs to a standard UAP-PRO inside the hull (Via either the injector or a TOUGHSwitch 8-port)

Ubiquiti UniFi UAP-PRO
Ubiquiti TOUGHSwitch 8-Port PoE PRO

Initial Steps

These instructions assume that your radio is set to FACTORY DEFAULT values. Please restore to factory defaults before proceeding. This is critical, especially if you are troubleshooting a problem. With your Windows 7 PC or Mac computer configured to the 192.168.1.x subnet, connect it to the radio using an Ethernet cable. The Ethernet port is auto-sensing. You are not required to use a cross-over cable. 

  • Using a web browser, enter 192.168.1.20 as the “URL” to gain access to the radio’s management console.
  • Enter “ubnt” as the administration account and “ubnt” as the password.
  • Configuration Instructions (change ONLY the items shown, leaving others at default values)
 

A. Choose the |Network| tab

  • Network Mode: Router
  • WAN Network Settings > NAT: [X] Enable
  • LAN Network Settings > DHCP Server> (*) Enabled
  • Press [Change] button
  • DONE with initial configuration

B. In order to use this radio as your new Wi-Fi adapter, you must:

  • Disable your devices internal Wi-Fi radio
  • Set your computer to “Obtain IP Address Automatically”
  • Plug the Ubiquiti radio into your device’s Ethernet port
  • Power-up your Ubiquiti radio, using Ubituiti ToughCable (shielded Ethernet cable) and the included Power over Ethernet (PoE) adapter. Note: Shielded Ethernet cable reduces the possibility of static electrical damage to the radio. It is particularly important when mounting in RV’s and boats.

C. Attach (as a client) to an Access Point

  • Log in to the radio’s management console at 192.168.1.1
  • Select the |Wireless| tab
  • SSID: [Select…] and choose the AP that you wish to attach to

NOTE: Think of “Signal” as a temperature. The “more negative” the “colder” or “weaker” the signal. Choose the most appropriate AP, with the strongest signal level as shown in this column of the “Site Survey” widow. Additionally, a signal that is “warmer” than -45 is “too hot” and may cause poor performance.

  • If it is protected with a Preshared Key, you will be prompted to enter it (and do so)
  • Press [Change]
  • Press [Apply]

Within approximately 10 seconds, you will have a connection to your selected Access Point

  • Close your browser (it is probable that its IP address has changed and you can no longer “Logout”).
