Interference
Interference happens when 2 APs with the same channels are placed near to one another. The
speed of the network drops and the signal strength fluctuates wildly.
Roaming
Association happens when the SSID, Encryption and MAC Address Control settings are correct
between the AP and client. If 2 APs with these same settings are located in the same area, the
client would choose to associate to the one which gives it a better signal strength. The client
would roam over to the 2nd AP when he moves nearer to it. The client switches AP and
frequency as he does so.
