I have just upgraded to version 18.104.22.168 and I am not seeing any active channels in the 5GHz band (see screen print)
The Laptop running inSSIDer is connected to my local network via the 5GHz band and I have View set to “2.4 & 5 GHz”. You can see from the Details that I am connected to Channel 155 , but nothing is showing on the graph.
Any ideas for me to try to resolve this? I would swear that this feature worked in previous versions of inSSIDer.
