Troubleshooting
If the solutions listed here do not solve your problem, contact your service provider.
You may have to reset the SBG6580 to its original factory settings if the gateway is not functioning properly (using the reset button will remove custom settings, including Parental Control, Firewall, and Advanced settings).
MODEM PROBLEM | POSSIBLE SOLUTION | |
|
|
|
Power light is off | • | Check that the SBG6580 is properly plugged into the electrical |
|
| outlet. |
| • | Check that the electrical outlet is working. |
| • | Press the RESET button on the rear panel. |
|
|
|
Cannot send or | • | On the front panel, note the status of the icons and refer to Front |
receive data |
| Panel Icons and Error Conditions to identify the error. If you have |
|
| cable TV, check that the TV is working and the picture is clear. If you |
|
| cannot receive regular TV channels, the data service will not |
|
| function. |
| • | Check the coaxial cable at the SBG6580 and wall outlet. |
|
| |
| • | Check the IP address. Follow the steps for verifying the IP address |
|
| for your system described in Configuring TCP/IP. Call your service |
|
| provider if you need an IP address. |
| • | Check that the Ethernet cable is properly connected to the |
|
| SBG6580 and the computer. |

send or receive data | • | Check the Security Mode setting on the Wireless Primary Network |
|
| Page: |
| • | If you enabled WPA and configured a passphrase on the SBG6580, |
|
| be sure each affected wireless client has the identical passphrase. If |
|
| this does not solve the problem, check whether the wireless client |
|
| supports WPA. |
| • | If you enabled WEP and configured a key on the SBG6580, be sure |
|
| each affected wireless client has the identical WEP key. If this does |
|
| not solve the problem, check whether the client’s wireless adapter |
|
| supports the type of WEP key configured on the SBG6580. |
| • | To temporarily eliminate the Security Mode as a potential issue, |
|
| disable security using the HTML configuration pages. |
| • | After resolving your problem, be sure to |
| • | On the Wireless Access Control Page, be sure the MAC address for |
