So I got the need to upgrade the firmware of my ADSL router. Found this link for latest D-Link firmwares.
I downloaded Version 1.00 (26/6) and got it uploaded to the router.
Everything works well, except that I think this upgrade is useless:
1. I lost the capability to have virtual wireless networks ( you know multiple network names with multiple permission but using only single router).
2. The initial idea for me is to fix the Dynamic DNS, because the last firmware I got the DDNS not updating (dlinkddns.com), so I thought it will be fixed in latest firmware.
3. I lost the TM built-in settings, need to fix it manually (yeah including lovely tmadmin username which is reset to admin).
So just don’t do it except there is a strong need to upgrade the firmware.
