This took me a few hours to figure out, and might save you a lot of time.
1. flash this exact firmware: routertech-ar7wrd-1350A-pspboot-firmware-4ports-20120130.zip - available here
2. give it 7 minutes or so to stabilise.
3. Login to router (read the documentation included in zip for username/pass/gateway ip)
4. go to System > RT Configuration
5. set led file to bewan700g, and DSP Driver to dsp71A.
6. Save changes, reboot.
I've tested and have had 24hrs uptime, all working.
Also, please add the Telkom Mega 105WR to the list of routers under that firmware file.
