I have two hidden wifi networks in range of my laptop (2.4 GHz and 5 GHz); immediately after a boot, I see only the 2.4 GHz network; the 5 GHz becomes visible only after a minute or two. After this delay, I can connect to it and use it, but the fact that I have to wait two minutes is somehow annoing.
$ lspci -k -nn | grep -A 3 -i net

My computer has a dual boot with Windows 10, and I don't have this issue; both networks are detected immediately.
I'm currently running Ubuntu 20.04 but I had this issue also with 19.10.
Is there any magic option I could try to speed-up the 5GHz network detection?
Thanks & best regards
