Does anyone know how i can update my Cisco 837 ADSL Router? I tried to use the link in the SDM however it asks for a username and password. When i enter my Cisco registered details i get another FTP login request and it does not accept my Username and password. I would also like to get the latest SDM manager software, however trying to find it on the Cisco website is useless. My IOS version is 12.4 (15) T6 and the SDM that i have is version 2.5.
Any help would be greatly appreciated.
