Beginner’s SETUP GUIDE for NANOSTATION-2 as receiver
and other Ubiquity devices using AirOS firmware V3.6
(Windows/MacOS)
This guide is primarily intended for mobile users (boaters, campers and truckers) who often
change access points. Fixed users can also use it, although there might be other more suitable
configurations for them.
Make sure the Nanostation 2 (Nano for short) is connected to your computer’s network card
with network cables, via the power injector (supplied with 12V either from the included wall-wart or
another 12VDC source). There should then be at least one LED lit on the back of the Nanostation.
On the original Nanostation shipping box, find and write down the default IP address (we assume:
192.168.1.20), the user name and password (should both be “ubnt”). Do not loose this information!
1) Set your computer to communicate with Nanostation
1a) Windows
1b) Mac OS X
2) Program Nanostation as receiver (station) and router
3) Choose and connect to a WIFI signal

Page 1
• Enable your network card: right-click on Local Area Connection and select Enable (if it’s
already enabled, the option would be “Disable” and just leave it as is).
• If there is a built in WIFI card, it should be disabled (right click and choose “Disable” if not
already so).
• Right click on Local Area Connection
and select Properties:
• If you do not need to share files or a printer on
your local network you should disable (un-tick)
“Client...” and “File and...”
for added security.
• WinXP: double click on Internet Protocol:
• Vista and Win7: double click on
Internet Protocol Version 4(TCP/IPv4):
• Fill in as pictured here:
We’re entering a static (fixed) IP address
This will be your computer’s IP *
This is always so
This is the IP of the Nano
*
Nano IP here too
(The Nano will be acting
as a DNS server)
* Note: The last number can be any number
from 1 to 254 except 20 which is taken.
• Click OK twice. There should be 2 LEDs lit on the Nanostation (power + network cable).
• Go to page 5.

Mac OS X
If the AirPort is on, best to turn it off:
Mac OS X 10.4
• Click on the Apple icon then System Peferences:
• Click on Network:
• Select the Built-in Ethernet:
• then click on Configure.
(Option: create a new Location configuration
named Nano to quickly return to
these settings in the future)
• Fill in as pictured here:
(= default gateway)
• Click on Apply.
• There should now be 2 LEDs lit on the Nanostation (power + network cable).
• Goto page 5.

AC OS X 10.5 (Leopard)
• Click on the Apple icon then System Peferences
• Click on Network:
(Option: create a
Location configuration
named Nano to quickly
return to these settings
in the future)
• Select Ethernet:
• Fill in like like this:
• Click on Apply:
• There should now be 2 LEDs lit on the Nanostation (power + network cable).
NOTE for other Mac versions: if you have two TCP/IP settings, then choose IPv4.
GENERAL NOTES
• AirOS firmware versions (firmware on a device is like the operating system on a
computer): the current version is AirOS 3.6 as pictured here in the screen shots. If you
receive a unit with a later firmware (or if you update it later), additional settings may be
visible.
• Directional antenna: The built in antenna points to the front of unit (LEDs are on back)
with a horizontal beam width of about 60 degrees.
• Resetting device: Should you be unable to connect to the Nanostation after changing
any settings (by mistake), it can be reset to it’s original default configuration (a hard reset)
by pressing the reset button (little hole, inside cover) for 20-30 seconds, with the power
on. The LED light should flash after releasing button.

2 Setting up the Nano
• Open your browser (e.g. Internet Explorer, Firefox, Opera, etc.) and type in address bar:
http://192.168.1.20 (the default address of the Nano) then press the Enter key.
• Type in ubnt twice and click OK →
(If this window did not appear, there may be
a problem with the wiring, the network card
or a firewall).
• Select the Network tab and change Nano settings as follows:
The Nanostation will act as a router
which makes WIFI cruising much easier.
(This refers to the WIFI side of the Nanostation)
The Nano will automatically be assigned an IP
address, gateway and DNS server by the WIFI
access point you connect to later.
(This refers to the local wired side = you)
This will be the Nano’s new IP address
Always so
Allows the LAN to communicate with the WLAN
Will allow you to connect a computer which has
it’s network setting to “Obtain an IP address and
DNS server automatically”.
• Click Change
Page 5
• You’ll notice that this now appears at the top of the window:
The changes made on the previous page are memorized but not yet
in effect. Only after clicking “Apply” with they take effect. Since we
still need to make some other changes, we’ll “Apply” them all later.
DO NOT APPLY YET!
• Click on the Advanced tab →
Verify items marked by ovals:
Change to Adaptive. The device
will choose the best of the 2 built-in
antennas (vertical or horizontal
polarization).
(Optional: adjust at which signal
strength the LEDs at the back of
the Nano light up)
Click Change
(Do not click Apply yet)
NOTES
• Just like there are several ways to skin a cat, the network settings of the Nanostation and computer can be
many. The settings here have been found most convenient while cruising because connecting to new WIFI
access points in different places require a minimum of effort.
• Since the default Nano IP address is in the very common range 192.168.1.x, and we cannot risk having
the same range on our own local LAN as the WLAN ashore, we have changed the original Nano IP from
192.168.1.20 to 192.168.10.20. We have also activated the Nano’s DHCP server which means that the computer
can get network settings assigned automatically (an IP in the range 192.168.10.100 to 200, plus the Gateway
and DNS server = IP of the Nano). We still need to set the computer to acquire the IP automatically (see end of
next page).

• Click on the Link Setup tab
→
Change Nano mode to Station
(i.e. receiver or ‘client’)
Make sure output power is on max
Leave rest as shown.
Click Change
• Click Apply when it appears at the top:
Now all the changes will come into effect.
YES
• Note: At this point communication with the Nano is lost because we still need to change the
computers IP address to be in the same (new) range as the Nano (192.168.10.x). The setting
can be either fixed (manually to e.g. IP=192 168.10.21, Gateway/Router/DNS=192 168.10.20),
or automatic which is simpler and more flexible (as it allows you to take the computer to another
wired network and automatically acquire the settings):
• Windows: refer back to page 1 and 2 to
open Internet Protocol Properties:
Change like this:
Then click OK twice.
• Mac OS: refer to pages 3 and 4 and change
Configure from Manually to DHCP, then
click Apply.
From now on, all these settings will remain in place and you’ll only need to take
step #3 to connect to an new WIFI access point. That’s a relief!

Connecting to a WIFI signal
• In the browser address bar type http://192.168.10.20 (the new address of the Nano) then press the
Enter key.
Clicking once on
• Click on the Link setup tab, then on Select (second line at right):
“Signal” will sort the
list with the strongest
one at the bottom
Select a strong signal
(without encryption)
by clicking in the button.
This is the
strongest in the list.
Any figure lower
than about 90 is
normally usable.
Then click “Select”
• Click on Change, wait; click Apply at top of new page, wait a few seconds for connection (some
access points take a while to connect). That’s it. There should be 3 or more LEDs lit on the back of
the Nano.
• Optional: to verify the connection, click on Main tab. This page has no settings, only information to
confirm a connection. (You may have to refresh the browser page after a while).
A number here
means that the
Nanostation has
associated with the
WIFI station
This number
will increase with
long distance
connections
A number here
means that the
Nanostation has
received an IP
address
(also see below).
Note: The numbers here tell us that the
WIFI access point has assigned all the
necessary numbers to the Nanostation
for connecting to the internet.
Numbers will vary with access points.
If blank, internet access will not work.
Page 8
• Clicking on Tools, Align antenna will bring up a received signal strength indicator, useful for
improving signals by rotating the Nanostation:
Since the number
is negative,
a lower figure
is stronger.
Moving this slider
allows the signal
bar indicator to
better display
different strengths.
• Assuming you have connected to an ‘live’ WIFI access point, you should be ready to access the
internet. This may involve logging-in to a marina or hotel welcome page, or paying for access.
• To connect to another WIFI access point in the future, just log-in to the Nano with your browser
and repeat step #3. Also see second recommendation below.
• An alternative to step #3 is to type “Any” in ESSID (second line on tab “Link Setup”), then Save
and Apply. From then onwards, the Nano will automatically connect to any un-encrypted access
point, without any intervention from your part. However, in locations with many WIFI signals, it
might not end up being the most desirable one.
• Connecting to an encrypted wireless network (WEP or WPA) requires knowing the encryption
key and performing additional steps in #3.
Recommendations
• For security, use a firewall (e.g. Windows firewall or free Zone Alarm) and a virus
scanner (e.g. Norton or free AVG).
• Make a bookmark (or ‘favorite’) to the Nanostation address (http://192.168.10.20)
and save the log-in info (ubnt; ubnt) in your browser for quick access.
• The supplied white cable ties for mounting the device may fail after exposure to
sunlight. It’s much better to use black ties, a good string, or hose clamps.
• If you do not use your computer elsewhere, you may prefer to give it a fixed
network setting (manually to e.g. IP=192 168.10.21, Subnetmask=255.255.255.0,
Gateway/Router/DNS=192 168.10.20), as this removes the initial delay of being
assigned settings when switching on the computer.
Online resources
• Download a more recent firmware (improvements and bug fixes; not necessary
but recommended) at: http://www.ubnt.com/support/downloads.
Once downloaded, log-in to the Nano, click on System tab, then Upgrade.
Previous configuration settings will not be lost.
• For an advanced manual on the AirOS firmware go to http://www.ubnt.com/wiki/
Main_Page and look under 802.11a/b/g Products.

ADDENDUM
Possible reasons for not getting online
• Cannot associate with AP (access point)
- AP fault or intentional restriction
- Your signal not good enough/ distance too far (using a directional antenna helps)
- Interference from many other WIFI users (using a directional antenna helps)
- Look for another AP on a less busy channel (as an example, in the USA only channels 1,
6, and 11 do not overlap/interfere with each other).
• Associated with AP (access point) but not online
- AP may be disconnected from internet
- AP’s DHCP server may not work and this would be evident on the Nano Main tab. If you
can find or guess the settings, then these can be enterned manually on Nano tab Network,
WLAN Network Settings: static. You’ll have to enter the IP (often 192.168.0.90 or 1.90,
Netmask 225.225.255.0), the Default Gateway (often 192.168.0.1 or 1.1) and at least one
DNS Server (208.67.222.222 goes to OpenDNS and will always work). Then Save and
Apply.
• If only some of your services work (e.g. Skype)
- It could be that only the DNS server is wrong or missing. Manually enter (as above) the
IP and Default Gateway that were assigned automatically, but change the DNS server to
208.67.222.222.
• Problems sending email with SMTP
- Your usual SMTP server may not accept your outgoing email if you get online via a different
provider and/or you are not autheticated. Your SMTP provider can usually tell you what
their authenticated connecting settings should be. Alternatively try another SMTP provider,
or use browser webmail instead of an email program (e.g. Outlook).
