need to see if I figure out why wpa_supplicant does that... or maybe just
remove the 2.4g for the list, its usefull if I need to take the laptop to
the bedroom, cause 5g won't reach there... while 2.4 does, but those are
really rare occasions...

I'm 99% sure it wasn't connected to the 2.4g when I run the results, but I
admit at the time I didn't look into ifconfig... since I had it cahnge to
5G just before...

In any case this is from now just to be sure:
