topic FCS error rate, whas is normal? in Wireless https://community.cisco.com/t5/wireless/fcs-error-rate-whas-is-normal/m-p/877649#M68396 <P>Looking in the WCS reporting, Performance and selecting an AP gives some clues about the AP behavior. I have always increased "FCS error rate for a/n and b,g interfaces" on daytime, with high figures on the y-axis.
