It depends on how long you have been counting them.
That many over a day or less would get my attention and I'd start looking for answers.
That many over a week or more wouldn't concern me. |

Fort Lauderdale, FL | Reboot your modem to zero the counter and have a look in an hour or so, then later in the day. If they are really going up fast, you probably have some sort of line problem. |

Fort Lauderdale, FL | I guess that's possible, and easy enough to check.
Can you take it to a friend who has DSL and test it there?
Or if you have a spare modem that counts these, try that one on your line for a while. |

Ha ha, check this out (observed during a thunderstorm on 5/8/08, Netopia modem, DSL 3558/384)
1st screenshot is at 3:41PM with 32,703 CRC errors.
2nd shot is 12 minutes later, CRC errors have just passed 100,000.
3rd shot is 4:53 PM, with 284,260 CRC errors.
And that S/N ratio display! Gives some insight into the mind of whoever programmed that stats page...
(If -4.50dB is bad, "-4.-50" must be *even worse*.  |
