Ubiquiti NanoStation 2

NanoStation2, NanoStation Loco2, LiteStation 2 and PicoStation 2

The following devices are not NanoStations but these devices use the same image as well. They most probably require snapshot builds.

• LiteStation 2 uses openwrt-atheros-ubnt2-squashfs.bin. Steps for flashing are the same as for NanoStation2.

Models of the Ubiquiti NanoStation family are quite similar to each other so the same images and instructions can be used for the listed devices.

Datasheets for all models are available from Ubiquiti.

• NanoStation Loco2
• LiteStation 2
• PicoStation 2
• Ubiquiti AirOS-based general product specs

The OpenWrt buildroot generates images that can be directly flashed to the NanoStation, usually with a name like openwrt-atheros-ubnt2-squashfs.bin (for the NS2 and Loco2).

When flashing those images, the Ubiquiti web interface will show a warning about unsupported third-party firmware. This warning can be ignored.

In order to upgrade from OpenWrt to a newer version, both the kernel mtd and filesystem mtd must be reflashed. The kernel is likely lzma compressed. If either mtd block isn't big enough, reflashing can not be completed through OpenWrt, but must be done through the RedBoot bootloader.

Recent versions of OpenWrt (8.09.2 and newer) support sysupgrade on this platform. To upgrade, put a combined firmware image into /tmp on the device and flash it using the sysupgrade command as outlined below.

cd /tmp
wget http://example.org/openwrt-atheros-combined.img
sysupgrade openwrt-atheros-combined.img

This can also be used to upgrade a device if you don't mind loosing your old config.

• Ethernet cable connection between PC and NanoStation. A switched connection or a bridged connection seems to work fine.
• Network settings of PC: 192.168.1.254/255.255.255.0
• TFTP client on PC
• NanoStation firmware file from Ubiquiti (not an OpenWrt image)

1. Turn off the device
2. Press the reset button
3. Turn on the device
4. Release the reset button ~10 seconds (but not longer) after turning the device on. You will know it's ready when the LEDs change.
5. Ping 192.168.1.20. If it works, you're ready to upload an image, if not, go back to step 1.
6. tftp the image in binary mode to 192.168.1.20 as 'flash_update'.

tftp 192.168.1.20
tftp> bin
tftp> put openwrt-atheros-ubnt5-squashfs.bin flash_update
Sent 1965199 bytes in 28.8 seconds
tftp> quit

or in Windows Dos prompt

tftp -i 192.168.1.20 put openwrt-atheros-ubnt5-squashfs.bin flash_update

7. Signal LEDs might be blinking during the upgrade. On a Nano5L, the power lights go back and forth. 7. Wait ~7 minutes before restarting or until the power lights stop their back and forth blinking. 7. Restart. The device should be back to its old configuration (OpenWrt doesn't overwrite or modify the NVRAM settings).

8. telnet to 192.168.1.1 and set a password with

passwd

To restore original firmware back you can't use mtd or sysupgrade but you have to use tftp method described above. (Note that the Nanostation will show up under 192.168.1.20 if everything is done correctly)

First put Nanostation in recovery mode via reset button on power on, and then flash original flash image via tftp.

If wireless does not work with eg. backfire 10.03.1 prebuilt firmware, and you get (in dmesg) “wifi%d: ath_attach failed: -22”, then you may need to run the following script by Bill Moffitt. WARNING: This script might brick your router (but it worked for me, User:green, on a NanoStation Loco2).

   byte=$(hexdump -b /dev/$partn |grep 0000270 |awk '{print $9}')
   if [ $byte -eq "000" ]; then
      echo "regdomain is zero" >>/etc/firstbootlog
      sync &&
      rm /tmp/mtdfile
      date >>/etc/firstbootlog
      echo "done with regdomain" >>/etc/firstbootlog
      echo "success" >/tmp/regdomain_success
   else
      echo "FAIL writing the file back to /dev/$partn - regdomain remains $byte"
   fi
else
   echo "Could not find partition" >>/etc/firstbootlog
fi

The two internal antennas work more or less automatically, using the driver's “diversity” setting to choose the correct one. Using an external antenna requires manually setting a few things:

sysctl set dev.wifi0.softled 0
gpioctl 7 0

These can be added to an init file in /etc/rc.d and /etc/init.d

In recent OpenWrt versions (8.09.1+) the antenna setting is covered by the wireless configuration. The corresponding option is called antenna and should be set within the wifi-iface section.

uci set wireless.@wifi-iface[0].antenna=mode
uci commit wireless
wifi

This device is an integrated wifi spot designed to be used outdoor. With Ubiquiti Firmware, AirOS 3 actually, it can act as station, station WDS, client, client wds... There is a dual patch antenna system able to work in vertical or horizontal polarity, or to send RF to an external RP-SMA female or SMA female connector (depending of date of manufacturing) - This feature is software selectable with AirOS.

• The Nanostation comes with a 12V power supply, the internal DC-Converter seems to be realized with a AP1510 PWM Control 3A Step-Down Converter. This can handle up to 23V. (untested)

also, hardware partically compatibility with TP-Link TL-WA5210G

There are two screws under the label on the back. The newer M2 and M5 versions have just one screw under the label and two plastic pins that can be lifted out of their holes by pushing a plastic cable tie end next to them. After removing these, the board can be removed.
