• But we are also seeing CRC errors on some of the fast ethernet ports in switch behind the router. Is this the result of bad packets being passed from the router to the switch, or could I be looking at two entirely different problems? Also of note is the fact that on the switch ports that are showing CRC errors, they are also showing input errors.
Out of interest, tried forcing my router (Draytek 2820) to use ADSL2(G.992.3) and it's been rock solid, with 0 CRC errors all evening and perfect streaming (abiet at 9656888 sync speed). So it seems I at least have an option to force a slower speed that's more reliable.

    • Jul 25, 2006 · "and why all the intermittant crc errors?" CRC is a way of adding up all the bytes or words in a packet; the sender does so and puts that answer into the packet also. The receiver makes the same calculation and compares. If the numbers are different then one or more bits in the packet must have changed enroute. Noise can easily cause this.
