The send light on my modem is blinking
The send light on your modem should be steady and indicates the upstream signal has been confirmed. If the send light is blinking it indicates a problem..
Check all the cables connected to the modem and ensure they are secure.
Unplug the power cord from the modem, wait 30 seconds, then plug it back in.
Wait for the power, send, receive and online light to go steady.
If the send light continues to blink, please contact Technical Support .
