Modem Troubleshooting Tips
If you are experiencing any problems with your high-speed service, try one or more of the following troubleshooting tips before calling SwitchWorks’ technical support team.
- Make sure that you have placed the phone filters provided with your kit on all of the phones, fax machines and other devices that are connected to a phone line. Make sure you do not put a filter on the line for the PPPoE modem. If you plan on using a splitter make sure to plug the splitter directly into the wall jack and place a filter on any of the outlets on the splitter that will not be connected to the modem.
- Make sure all physical connections (power, phone and network cables) are firmly and securely connected.
- Try powering off the modem for a few seconds and powering it back on again. If you are using a router, switch or hub, make sure to power them off too and power them back on only once the PPPoE modem is up and running.
- Try using different phone and network cables.
- Try disconnecting all phones, faxes and other devices and then powering the modem off and on.
- Try connecting the PPPoE modem to a different phone outlet than the one you are using.
