I normally keep my 5Ghz WiFi disabled. When I try the Self Diagnostic tool it shows that there is a problem and that attention is needed, giving me the phone number, but it's not saying why. The reason in the 5Ghz WiFi being off and having a 14.2.2 State Code.
The app not stating what the problem is could cause people like me to call, thinking there is something wrong. I immediately figured that it was tied to the State Code, which I verified by enabling the 5Ghz band and running the test again, so it wasn't a problem for me, but others who have a WiFi band disabled might not know that.
I know that it's not exactly easy to implement something like that, but for future versions it may be a good idea to not only say that there is a problem, but also to say what it actually is.
