I am looking for DDNS to be added. I have purchased this modem for same. i have called Dlink , They have sent one firmware as well . E5.2T01-2-DL-R1B040-IM.EN_UPGRADE . But can't upgrade. some fatal issue while upload using GUI. Do you know how to upgrade firmware via tftp or telnet..
Its very old thread but I am facing same issue. I need DDNS and this product is shipped with 11 Jun 2010 FW. D-Link team gave me same FW which gives me Fatal error. Do you have updated FW?
If yes Please share.
