Resolution
If the base station is not communicating with the WLAN, check the three LEDs on the top panel. They report network and modem activity, operational status, and radio activity.
The base station uses a blinking LED code to identify error conditions. This code sequence uses a two-digit diagnostic code that starts with a long pause to delimit the code, followed by the LED flashing red to count out the first digit, then a short pause, followed by the LED flashing red to count out the second digit.
