WiFi in 5 GHz frequency range
Normally I let my wireless access points operating in the 5 GHz frequency range. The 5 GHz frequency range has more channels and less interference from other devices like micro wave ovens, bluetooth, and so on.
Just enabled on one of my wireless access points (running as rogue detector) the 2.4 GHz WiFi. I was quite surprised how bad and overloaded the 2.4 GHz frequency in my area is.
Disable 2.4 GHz
My conclusion is to always disable 2.4 GHz and use 5 GHz only.
