Can I turn UEFI (it's bios to me), can I turn UEFI secure boot off? I'm the only one that will use this the laptop and it gave me fits when trying to fix my wifi. I don't want it to get in the way of fixing other problems (printer, etc....)

If so, any tips on which menu it's in to turn it off (in UEFI) or url links please.

Secure boot is mostly Windows protection, you don't need it.
Typically you would toggle it off in the security section/tab of System (BIOS) settings.
To get to System settings is usually accomplished by hitting the designated hot key when the computer logo/splash first appears upon boot up.

As to which key and how to navigate your System settings....
Kinda hard to guide you without knowing the make and model of your computer.

Secure boot affects only the booting process, do not expect it to resolve problems with wifi, printing or whatever. That said, it can be turned off somewhere in bios (yes, I know) menus or via mokutil (never tried it).

Ther person helping me resolve my wifi issue last night, thought so too. But when I ran the command "sudo apt-get install --reinstall bcmwl-kernel-source", it absolutely stopped me mid process and made me make a password and reboot and enter the password, before it would allow me to run the command completely.

Thanks. I turned it off.

Yes, a little of a useless pain for the consumer. The way I see it, Intel was the brainchild of UEFI, but only went so far, and basically handed it off to a consortium of sorts which developed it even further. Microsoft got heavily involved as they saw an opportunity to gain a little control over the hardware supporting their OS which is under constant attack. Their strategy, which is just my opinion here, is that if the consumer wants to customize their computer that was designed for Windows, you will need to get Microsoft's approval to make the modifications.

So that's where the signatures come into play, however, computer manufacturers and Microsoft are both aware that you still need to give the consumer some control over the hardware they paid for, which is why for now at least, you can disable Secure boot.
