Your DSL modem has several Indicator lights on the front, which can be used to diagnose installation and connection problems. The lights on the Wireless and standard DSL modems may be labeled differently and there are three ways to tell if your DSL modem is also a wireless modem or a standard modem.

  • Power switch: Wireless modems have an On/Off switch in the back, while non-wireless modems do not.
  • Modem's model number: Wireless modem's model number is 4011G, while standard modem's model number is 2071. You can locate the model number just below the modem indicator lights.
  • Serial number: Wireless modems have an alpha numeric serial number (i.e. the serial number contains both numbers and letters, like AB12C3). If the serial number consists of only numbers, it is not a wireless modem.
  • Standard modem Indicator lights:
