Re: Problems with WiFi networks - HP 255 G7, FreeBSD 14.2

The suggestion of trying FreeBSD 14 STABLE ended with success.
I can use WiFi correctly now.

One good thing i noticed is that i dont need to type anymore that
"linuxkpi..." in /boot/loader.conf anymore for the WiFi card to work
correctly.

I'm really thankful for all your help.
I want to keep digging on this system and now its more easy.

By the way, thanks for made me know about the risks of one of my text
files, however, i tought about it beforehand, and found that i had reasons
to not care about that for now.
Again, thanks for the help.
