Explanation
Interference from neighboring wireless networks is primarily an RF (radio frequency) issue caused by multiple APs operating on the same or overlapping channels. Configuring the AP to use a different, non-overlapping channel (such as 1, 6, or 11 in the 2.4 GHz band) minimizes interference from adjacent business networks. PPPoE is an authentication/encapsulation protocol for DSL connections and has no effect on wireless RF interference. MAC filtering controls which devices can connect but does not reduce RF interference. WPA encryption secures data in transit but also does not affect the radio channel interference.
