Its been yonks since I retired my 3b, but I don't recall it having 5G in 
its radio, only the 2G 11 channel.  And I can't scan with the rpi4b that 
replaced it, nasty neighbor was stealing my bandwidth to the tune of 
80Gigs a month, so all radios are disabled here. Karma caught up to him 
and he did a year n the gov's economy hotel. His woman threw him out, 
but I've never bothered to turn my radios back on, lots more peaceful 
that way when you need a piece of cat6 to get into my machines.
