I tried to download the firmware for my D-Link DSL-502T,from the link
above, to be upgraded from current firmware ( V1.00B06.AU) to the latest
version (v2.00B12.AU) which supports ADSL2/2+, but the upgrading failed for
both options : Web and exe file.
For the option A ".exe file", I received this error message : "TFTP
timeout",,,,,for the option B "via web" I received this error message:
"Upgrade Failed"
Although I have followed all the instructions like assigning static ip,
restore to factory default,etc.
