Basic Troubleshooting

Power Cycle

Modem: Power cycling the modem or pulling the power and letting it sit for 30 seconds before plugging it back in, accomplishes several things.  It resets the connection to the network and forces the connection to be re-established.  It also causes the electronics and software in the modem to reload.

Personal Devices:   Just as a modem has hardware and software that needs reset from time to time, your personal devices such as computers, tablets, smartphones, etc., all can benefit from being shut down completely and started back up, so the software loads fresh.

Verify cords are all securely connected

Phone:  Pull the cord out of the modem and jack, then re-seat it back in the modem and wall jack to ensure you have a good connection.  Swapping cable ends is a good practice.

Power: Verify that it is plugged in to a working outlet, has a tight connection both to the wall receptacle and to the modem Power jack.

Ethernet: Disconnect from the modem/router and device. Re-seat connections, this is a good time to swap ends of the cable.

 Filtering

Modem: needs to be unfiltered or using a filter splitter if the jack is shared with a telephone.

Phones: All phones need a filter.  Filters are available from the InterBel Business Office.  Install filters directly to the wall jack with the line cord coming out of the filter.

Other Devices:  Any device that connects to your phone line up to and including fax machines, alarm systems, etc., require a filter.   

Note: Filtering can be done at the outside NID, where your service comes into your home.  When this is the case, our technicians will inform you that filters are no longer needed or if they are only needed in specific locations.

 DSL Light

Blinking:  The modem is not connecting back to the network.  Most common causes of this are wiring issues, filtering issues or device failure.

Solid: Indicates the modem has a connection back to the InterBel network.

Back Panel

1. Attach the antenna and point it up.

2. Do one of the following for your Internet connection:

  1. DSL WAN: Use a telephone cable to connect your ZyXEL Device’s DSL WAN port to a telephone jack (or the DSL or modem jack on a splitter if you have one).
  2. ETHERENET WAN: If you already have a broadband router, fiber optic connection or modem, use an Ethernet cable to connect the ETHERNET WAN port to it for Internet access.

3. LAN: Use and Ethernet cable to connect a computer to a LAN port for initial configuration and/or Internet access.

 4. USB: Connect a USB (version 2.0 or lower) memory stick or USB hard drive for file sharing. Use a USB extension cable if the stick is too big to fit.

5. Power: Use the provided power adaptor to connect the POWER socket to an appropriate power source. Make sure the power at the outlet is on.  After connecting the power adaptor, look at the lights on the front panel.
