CRC errors and router

Ive noticed ever few week of having a rock solid connection with very few errors, i will suddenly get loads of CRC errors that will effect throughput. Could be talking 100+ every minute. Could happen anytime of day. Anyway if i reboot the router and reestablished connection the errors suddenly stop and im fine for another few week

So could a router cause this behaviour? I was always under the impression CRC errors were caused by outside interference (lightning, REIN etc) on the line. If this is the case why does a reboot fix it?

When you reboot the router will look at the frequencies it can use and if still seeing errors may avoid a particular frequency, hence why after a reboot you see less of the errors.

Routers will hang in and tolerate some errors, since this is usually preferable to a 30 to 60 second re-sync phase.

Ah makes sense, cheers

Yea i usually get 50-80 and hour which doesnt noticably effect my comnection
