Can you connect to the Dlink and get to the configuration screen?
1. Launch your Web browser. Enter "http://192.168.0.1"
into the address bar and press the "Enter" or "Return" key.
2. A logon pop-up screen will appear. Type "admin" for the username and leave the password field blank.
3. Click "OK". A D-Link configuration screen will appear.
If it remembers, you may need to use your username and password.
Did anything interrupt the firmware upgrade?
