AREDN - Amateur Radio Emergency Data Network

Special note on macOS, when using TFTP on the command line, be sure to navigate to the folder where your binary file is (.bin) and then start the process of 'tftp 192.168.1.20'. This will avoid any issues of “missing files” when you go to run the put command. https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=223513

This set up is the exact opposite of the Ubiquiti's flashing, whereas these devices, the routerboard is a TFTP client, and your computer will act as the TFTP server to push the binary file. Follow the instructions here, and preferably, use a Windows machine to save yourself time unless you are well versed in Linux: https://www.arednmesh.org/content/installation-instructions-mikrotik-devices

1. Download and install the pxe server at the following link. http://reboot.pro/files/file/303-tiny-pxe-server/. Suggest unzipping the file into a location convenient to you.
2. Within the folder where you have installed the pxe server, open the config.ini file into notepad. Underneath the line that says {dhcp} add a line as follows:

   RFC951=1

3. Save and close the config.ini file
4. From the following link, download the following two files:

   aredn-xxx-xxxxxxx-mikrotik-vmlinux-initramfs.elf

   and the file the firmware file appropriate to your device which in this case will have 'AC' in it.

   aredn-xxx-xxxxxxx-mikrotik-rb-nor-flash-16M-ac-sysupgrade.bin

5. Save these files into a folder named firmware on your desktop so that you know where to find them later.
6. Configure computer’s Ethernet device:

   IP - 192.168.1.10

   Subnet Mask - 255.255.255.0

7. Power on the Microtik device and plug a Ethernet cable from INTERNET port of Microtik to computer’s Ethernet port
8. Launch the Pxe server, click the online button and confirm that the ip address in the Option 54 line is the 192.168.1.10.
9. Copy the .elf file that you downloaded into the files folder in the Pxe server folder.
10. Rename the .elf file you just copied to rb.elf
11. In the Pxe program select the rb.elf file into the firmware line.
12. Uncheck the filename button just below the firmware line. This is important
13. Press the online button in the pxe server software
14. Disconnect the Ethernet cable from the internet port on the Microtik device.
15. If the security alert window pops up check both boxes and accept. The device is now in a state to accept the firmware upload.
16. Plug the Ethernet cable back into the internet port of the device.
17. While holding in on the reset button of the device, plug in the power cord. It may be necessary to hold the reset button for a full minute. As soon as you see activity between the device and the pxe software you can release the reset button.
18. Press offline button in the pxe software
19. Unplug the Ethernet cable from the device.
20. DO NOT UNPLUG THE DEVICE FROM POWER AND ALLOW AT LEAST THREE MINUTES FOR THE DEVICE TO STABILIZE. THE DEVICE HAS NOT RECEIVED THE AREDN SOFTWARE AT THIS POINT AND MUST NOT BE UNPLUGGED FROM POWER
21. Switch the Ethernet cable from the internet port to port two of the device.
22. Goto your browser and type in 192.168.1.1. you should now be in the AREDN software.
23. Go into the setup screen. The default user is root and the password is hsmm.
24. Configure just your SSID, and admin password for the device. Admin username will always be root.
25. Click Save Changes, then reboot.
26. Log in again to the setup screen.
27. Upload the sysupgrade.bin file by going under the administration tab at the top. The first section will have the firmware upload.
