CRC errors on you wireles system are ususlly an indication of RF interfreence, sources could be Microwave ovens, bluetooth devices, cordless phones, other AP's operating on an overlapping channel, clients broadcasting Probe requests, Wifi printers with the Wifi enabled but not configured,and any other device that operates in the 2.4 or 5.8 bands used by the abg devices.

for wireless systems the CRC errors are common the rule as for all networks is to establish a base line for your environment and then when a problem arises check the current error rate against your base line for a clue as to the source of the problem.

Thanks for the response Bill, I thought this could be the case. I'll baseline after a week of operation.

Thanks for the Points

As always it is the client that will determine if the network is meeting their needs.
