Pre built WTP Firmwares
We release a set of firmwares for a selected number of wireless routers. The default root password for all the images is empower. All images are pre-configured to use 192.168.100.158 as the controller.
The following platforms are supported:
- PC Engines Alix 2D (website)
- PC Engines APU 2D (website)
- TP-Link WDR4300 (website)
- Netgear WNDR 4300 (website)
We will add more pre-built firmwares shortly. Please contact us if you would like to see a particular platform officially supported. Please consider that we will upload only firmwares that we can test, meaning that we must have the actual wireless router in our lab.
Firmwares can be downloaded from the releases page. Instructions for uploading them onto the wireless routers are provided in the following sections.
Alix boards are manufactured and sold by PC Engines. They utilize the x86-based AMD Geode CPUs. The boards and other components (enclosures, power supplies, wireless cards, CompactFlash cards, etc) are sold separately, although some retailers sell pre-build kits.
A picture of one of the Alix WTPs in our lab is reported below. Notice how they are equipped with two Wireless 802.11n NICs, hence the reason for the four antennas.
The EmPOWER firmware downloaded from the releases section:
The easiest method of installation for ALIX boards is to use the dd command. Notice that after you do this the first time you can also update the firmware using the router web interface. Attach a USB CompactFlash reader/writer to the flashing machine and insert the CompactFlash card.
Watch the output from the dmesg command to see what device ID it has picked up (it will be something like /dev/sdb). Ensure that /dev/sdb (or whatever is determined in the previous step) is not mounted through the use of the 'mount' command. If it is, unmount it with umount.
Flash the image to the CompactFlash card with:
dd if=openwrt-x86-geode-combined-squashfs.img of=/dev/sdbRemoved the CompactFlash card, place it on the ALIX board, and power it up.
The eth0 interface (the one close to the power plug) is the WAN interface and it is configured to obtain an IP address from a DHCP server.
The eth1 interface is the LAN interface and is configured to give IP addresses on the 192.168.1.x subnet. The wireless router itself is reachable from the LAN interface at the 192.168.1.1.
APU boards are manufactured and sold by PC Engines. Boards are based on AMD Bobcat low consumption CPU. The boards and other components (enclosures, power supplies, wireless cards, CompactFlash cards, etc) are sold separately, although some retailers sell pre-build kits.
A picture of one of the APU WTPs in our lab is reported below. Notice how they are equipped with two Wireless 802.11n NICs, hence the reason for the four antennas.
The EmPOWER firmware downloaded from the releases section:
The easiest method of installation for ALIX boards is to use the dd command. Notice that after you do this the first time you can also update the firmware using the router web interface. Please refer to the flashing procedure for ALIX boards for detailed instructions.
Notice that in the APU the ethernet interface order is reversed and that the eth0 interface is the one next to the serial interface.
The TP-Link WDR4300 is a commercial WiFi router equipped with two 802.11n interfaces and Gigabit Ethernet. The router supports Dual-Stream (2x2) on the 2.4 GHz Band and Triple-Stream (3x3) on the 5 GHz Band.

The EmPOWER firmware can be uploaded directly from the router web interface.
- openwrt-ar71xx-generic-tl-wdr4300-v1-squashfs-sysupgrade.bin, this can be used to re-flash a router that is already using the EmPOWER firmware, for example, because you were to reset to the initial configuration or because a new version of the firmware has been released.
The Netgear WNDR 4300 is a commercial WiFi router equipped with two 802.11n interfaces and Gigabit Ethernet. The router supports Dual-Stream (2x2) on the 2.4 GHz Band and Triple-Stream (3x3) on the 5 GHz band.

- openwrt-ar71xx-nand-wndr4300-squashfs-sysupgrade.tar, this can be used to re-flash a router that is already using the EmPOWER firmware, for example, because you were to reset to the initial configuration or because a new version of the firmware has been released.
