The PicoStation2 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.
PUT THE LINK TO THE FIRMWARE HERE…JUST DONT SAY "USUALLY WITH A NAME LIKE …." This does not help people at all :(
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.
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.
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.
