I have two Aironet 1100s (channel 1 & channel 11) in a classroom. I've noticed a lot of Header CRC and CRC errors in the radio statistics. What causes these errors?
CRC errors and PLCP errors can occur due to Radio Frequency interference. The more radios a cell has (APs, Bridges or Clients), the more are the chances of the occurrence of these errors. A cell means a single channel (for example, channel 1) or a channel that overlaps the channel. Radio interfaces are half duplex. For more information on this read
