Common mistakes.

B. The SSID is the network name and is a logical identifier; changing it has no effect on radio frequency interference between networks.
C. Firewall rules control which traffic is permitted or denied on the network and have no impact on wireless RF channel interference.
D. Encryption (WPA2, WPA3) secures data in transit but does not change the radio frequency used, so it does not reduce RF interference.
