Micro Edge builds on Linksys WRT devices are available in beta for home lab environments. Production deployments should use one of our supported platforms; eSeries appliances or VMWare.
Micro Edge on the following Linksys WRT router models:
- Linksys WRT-1900ACS
Important: The model number must be precise. For example, the WRT1900AC is not the same as the WRT1900ACS.
Step 1. Download the Micro Edge firmware
Download the latest version of the Micro Edge firmware from the downloads area of your ETM Dashboard account.
Step 2. Flash the device
In the Linksys administration UI click Connectivity.
In Router Firmware Update click Choose File and browse to the Micro Edge firmware image.
After the file uploads successfully, click Start to begin the flashing process. Flashing takes approximately two minutes. Do not turn off or reboot the device during this time.
Step 3. Connect to Micro Edge
After approximately two minutes, the flashing process completes. At that point, renew the IP address of your management computer.
Important: if you are connecting wirelessly, you must reconnect to a new wireless network named ‘Untangle’ with WPA2 password ‘12345678’.
Reset to Linksys Firmware
In case you need to revert to the original Linksys firmware, refer to the options below.
Download the Linksys firmware.
Rename it something like firmware.bin to make the following instructions easier.
Option 1 (Intermediate)
- Download an SSH program if necessary (ssh for linux, putty/winscp for windows, ssh on mac)
- scp the firmware to /tmp on your Micro Edge device.
- ssh to your router (as root using the password configured for “admin”)
dd if=/tmp/firmware.bin of=/dev/mtdblock4 bs=1M
dd if=/tmp/firmware.bin of=/dev/mtdblock6 bs=1M
- reboot the device
Option 2 (Advanced)
If you have a USB tty connected, you can do so with uBoot and TFTP via some simple commands. This requires cracking open the case and connecting your USB serial adapter to access uboot. Then connect a LAN port to the TFTP server (or the network with the TFTP server) Assuming the TFTP server is at 192.168.1.20, do the following:
setenv ipaddr 192.168.1.100 setenv serverip 192.168.1.20 setenv firmwareName firmware.bin run update_both_images boot
