Installation using the OEM web interface
The easiest way to install OpenWrt is by using the firmware utility of the OEM web interface:
Connect to the WebInterface at http://192.168.11.1 and go to "Administration" → "Firmware Upgrade"
Upload the OpenWrt-Image you want to install, e.g. https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-factory.bin
Make your PC obtain a new IP address from OpenWrt (
pump -i eth0or
proceed with basic.config to complete installation
NOTE: It may happen, that the squashfs-factory.bin does not work for this device, if the factory image is based on DD-WRT. See this thread. Please update the thread with your experience or file a bug if you run into a problem. According to the user, for installation from DD-WRT the instructions on the WZR-600DHP page worked for him.
Installation using the TFTP method
Specific values you need
|Bootloader tftp server IPv4 address||192.168.11.1|
|Bootloader MAC address (special)||02:aa:bb:cc:dd:20|
|Latest firmware tftp image||http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin (
|TFTP Transfer Window||4 seconds|
|TFTP Window Start||approximately 10-20 seconds after power on|
|TFTP Client Required IP Address||192.168.11.2|
Here is a link to the console output of the boot process, with all led's in view for reference http://www.youtube.com/watch?v=mAZNTKhpHig
The red "DIAG"-LED begins to flash rapidly when the router has received the image and is currently booting the new firmware.
Successful flashes via tftp using Windows 7 directly plugged into the router have been done. It helps to add arp entries and disable media sensing as per the generic tftp instructions.
Flash should have reset all settings as well. The IP address of the router should be 192.168.1.1 now since 192.168.11.1 is only for the bootloader at boot-time
If your router has two red flashes of the DIAG LED followed by no flash and repeats then the flash failed or the image given is corrupt. You can still recover with tftp. Start over and try again.
TFTP advice, wrong region
There are apparently several regional versions of the OEM firmware. You may have to adjust the region in u-boot first. Below is example of a successful region change and flash procedure. Source: forum article
This is how to do it from serial console:
Power on the router and wait until you see "Load address" appear shortly after the tftp message:
tftp server(receive) go, waiting:4[sec] ... Load address: 0x84000000
Immediately press Control+c
After prompt apears do:
setenv accept_open_rt_fmt 1
setenv region EU
(it reboots now)
After Reboot Power your Device down!
Set Your LAN IP to 192.168.11.2
In a linux terminal use these commands
sudo ip neigh add 192.168.11.1 dev eth0 lladdr 02:aa:bb:cc:dd:20 nud permanent <enter>
tftp 192.168.11.1 <enter>
<powerup your device and wait 12 seconds>
put firmware-tftp.bin <enter>
In Windows cmd put that Line:
arp -s 192.168.11.1 02-AA-BB-CC-DD-20
tftp -i 192.168.11.1 PUT wzrhpag300h-pro-v24sp2-19154.enc (don't hit enter, yet)
Power on the Device and 10 Seconds after that hit enter in Windows CMD to start the TFTP. (it tooks about ten Minutes to Complete the flash procedure)
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Press the 'USB/eject' button while the red 'DIAG' LED is blinking to enter Failsafe mode.
LED for USB-Devices
If you want to trigger a LED as soon as an USB-Device is connected to your USB-Port, add this to /etc/config/system:
This switches on the little red circle of the DIAG-LED everytime you connect something to your USB-Port.
It's very unlikely that you completely bricked the device, so first try the TFTP Method above. Note that a red diagnostics light blinking twice means your flash failed, but the device is ok and tftp will work (keep trying). If you still get nowhere, more drastic measures:
