Tutorial on how to flash the Telkom Mega 105WR

In my previous post here, I detailed how I flashed the firmware of my old Telkom Meaga router. Per a request in the comments to that post, I’m writing a quick tutorial on how to flash your Telkom Mega. Please be aware that flashing the device with the RouterTech firmware will invalidate any remaining warranty on the router, and there is a chance you can brick the router.

Do as follows:

  1. Register at routertech.org and sign in. Follow the download links to where you are able to download the firmware. For the Telkom Mega 105WR, you will want to download the “routertech-ar7wrd-1350A-pspboot-firmware-4ports-20120130” or similar file, depending on the date. Unzip this file to a folder anywhere.
  2. Login in to the Mega 105WR’s web page. Click the Advanced menu button at the top and then on Restore to Default on the left hand side of the page. This will reset the router to factory defaults. This is a required step.
  3. Alternatively, press and hold the physical reset button on the back of the router for about 30 seconds. This will do the same thing as step 2, and is useful if you can’t get into the router’s web management page.
  4. You should now be able to log into the router’s web page at Once there, click on the Advanced button on the top, and then click Firmware Upgrade on the left hand side of the page.
  5. Click the Browse button to find the RouterTech firmware.
  6. Chose the “RouterTech_3.7.1B_1350A_20120130_2.97_AR7WRD_psbl_firmware.upgrade” file in the root of the unzipped folder from step 1.
  7. Click on the Update Gateway button.
  8. Walk away from your PC, or play cards for roughly 10 minutes. DO NOT attempt to do anything on the router, ping it and so forth.
  9. After 10 minutes, refresh your computer’s IP address. It should now be in the 192.168.1.x range. If this is so, then the firmware has been flashed correctly.
  10.   Log into the router’s web page at The default user name and password is Admin/Admin
  11.   Click on the Advanced Menu button at the top, then on Restore to Default. The router will factory reset again. This is the last time you will need to do this step.
  12.   To make the LED lights on the front work properly, you will need to change the LED configuration file. Go to the System button on the top menu, and then RT Configurations on the left. When you see the option to change the LED configuration file, use the bewan 700 (or something similar, the name escapes me right now) model. Restart the router when asked, and you are done.

Now you can further configure the router as you need. All the options of the old Mega firmware are there, along with plenty of other options. I must stress that I haven’t yet let the Mega run for extended periods, so I can’t tell if the RouterTech firmware will fix the problems the original firmware had. Still, it’s worth a shot and it may help you out. I’m always open to feedback.
