Few months back, I was using D Link DSL 2640U modem. I had some problems with it. When I upgraded my modem, I downloaded different version number unknowingly and upgraded it. I got fatal error and now I am unable to use the modem. Can’t either connect to internet or log in to modem’s IP address. I tired resetting the modem, too. But it’s of no use. Is there a solution for my problem?
