Gateway LEDs flash, receive
modem READY LED off or
flashing
If the Gateway does not seem to be functioning and its STATUS
LED flashes amber, and the receive modem READY LED blinks
or is not lit, as shown in Figure 48, take the following steps.
• Check to make sure the USB cable is securely attached to the
Gateway and receive modem. See Figure 46. If the cable was
loose, the Gateway and receive modem READY LEDs will
come on when it is reattached.
• If securing the USB cable does not solve the problem, check
all cable connections. Tighten any that seem loose.
• If the Gateway STATUS LED still does not come on
continuously, power cycle the DW4020 by unplugging the
power cord from the wall outlet or surge protector, waiting
ten seconds, and plugging it back in.
• If the problem persists, contact technical support.
