The PicoStation2 (and the PicoStation5) are supported by OpenWrt.
The OpenWrt buildroot generates images that can be directly flashed to the Picostation trough the Ubiquiti web, usually with a name like openwrt-atheros-ubnt2-pico2-squashfs.bin.
When flashing those images, the Ubiquiti web interface will show a warning about unsupported third-party firmware. This warning can be ignored.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the sysupgrade command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload "openwrt-ar71xx-ubnt-rspro-squashfs-sysupgrade.bin" file to LuCI
- Wait for reboot
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade:
cd /tmp/ wget http://downloads.openwrt.org/backfire/10.03.1/ar71xx/openwrt-ar71xx-ubnt-rspro-squashfs-sysupgrade.bin sysupgrade -i /tmp/openwrt-ar71xx-ubnt-rspro-squashfs-sysupgrade.bin
This can also be used to upgrade a device if you don't mind loosing your old config.
- Ethernet cable connection between PC and PicoStation. 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
- PicoStation firmware file
- Turn off the device
- Press the reset button
- Turn on the device
- Release the reset button ~10 seconds (but not longer) after turning the device on. You will know it's ready when the LEDs change.
- Ping 192.168.1.20. If it works, you're ready to upload an image, if not, go back to step 1.
- 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-ubnt2-pico2-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-ubnt2-pico2-squashfs.bin flash_update
7. Signal LEDs might be blinking during the upgrade. On a PicoStation2, 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
To restore original firmware back you can't use mtd or sysupgrade but you have to use tftp method.
First put Nanostation in recovery mode via reset button on power on, and then flash original flash image via tftp.
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
