Appendix A Troubleshooting 25
The cable modem’s STS light blinks for 5 minutes, goes off,
comes on again, and repeats.
Check with your cable service provider to make sure that high
speed access is available and running.
In rare instances, the cable signal may be weak or noisy. Be sure
the modem is attached to one of the ports on the first splitter after
the cable enters your home or office. Refer to the following dia-
gram or contact your cable provider.
Make sure there is no video amplifier on the same line with the
cable modem. (A video amplifier prevents data from returning to
the cable service provider's central office.)
Note:
Sometimes, when your cable modem service is restored
after a disruption, you may experience difficulty communi-
cating. If this happens, disconnect and reconnect the
power, and let the modem perform the automated syn-
chronization process again.
