I would like an explanation as to why i can no longer log into the administration page for the SMCD3GN unit. Was there a firmware update that disabled this feature? This would also explain why the Link light is no longer on.
Im assuming you are able to see the login page for it? Your still getting internet otherwise?
The link light, from my understanding, will only be on/blinking when there is an ethernet connection to the router (i could be wrong on this)
Its possible if it was hard reset, that the login/password was set back to the default. But then everything would be, the SSID, etc.
I had the same issue. It seems that there was a firmware update to the router and it reset the default gateway to 192.168.0.1. It also changed the passwords for the rogcesadmin and the cusadmin.
I called the tech support guys and they were able to reset the modem wipeing all my configuration settings.
Small price to pay for admin access.
Once they did this he was kind enough to login and set the password for me and I reconfigured the router.
