APs Detect Errors but Do Not Change Channels
First, ensure that ARM error checking is enabled. The ARM Error Rate Threshold should be set to a percentage
higher than zero. The suggested configuration value for the ARM Error Rate Threshold is 30–50%.
APs Don’t Change Channels Due to Channel Noise
APs will only change channels due to interference if ARM noise checking is enabled. Check to verify that the ARM
Noise Threshold is set to a value higher than 0 dBm. The suggested setting for this threshold is 75 dBm.
