D-Link DSL-2640U H/W Rev. C2 UPnP DLNA Network Issue

I had this ADSL router and it was working fine. Recently I tried to connect it to my LG Smart TV to stream media contents but my TV didn’t recognized at all!

I did some researches over the Internet, most of them was in Russian language so i decided to write this post to help international users of this device.

My router’s version was ME 2.01, I have found that this issue caused because of blocking SSDP packets in WLAN interface, luckily I have found that the latest firmware version RU 2.05 solved this issue, so I updated my device firmware to the latest version and finally this issue has been solved and now I can stream my favorite content to my TV!

Here are the changes log from 2.01 to 2.05:

RU_2.05
1. Removed lock SSDP packets from a wireless interface.
RU_2.04
1. Correction of errors PPTP-client to connect to a remote VPN-server over PPPoE interface, and MER.
2. Correction of errors when trying to use PPTP-client as the default gateway.
RU_2.03
1. Correction of errors in the function of PPTP-client.
RU_2.02
1. Fix for IPSec.
2. The web interface adds the ability to create static routes without the IP-address of the gateway.
3. Blocked access to the device for Telnet using the account 'user'.
RU_2.01
1. Fixed problem with disabling SNMP.
2. Automatically update the page and return to the home page after the firmware update procedure.
3. Fixed arbitrary changes to the MAC-address 02:10:18:10:10:01.
