Installing driver for USB wifi adapter - completely lost

I have three separate USB wifi adapters. All work in Windows. One says Linux compatible on the package (I'll call it "A"). It even comes with Linux drivers.

I used lsusb.

I see the two of the adapters, but not the one which specifies linux compatability and came with drivers.

I copied the drivers for "A" to a folder in my home folder I called wifi. I clicked properties on install.sh and clicked 'allow executing'. I executed it and it seemed to install some drivers, I was asked for my password twice. But still, the USB is not showing up in lsusb.

The other two usb adapters (I don't really care which one I use, as long as it works) show up on lsusb. How do I install the drivers?

One is an Asus (Broadcom BCM43526) The other just says ID: 2001:331a D-Link Corp. (Its the Death Star looking USB3 usb wifi adapters..Yes, its pretty cool).

So, I know you all get asked this many times a day, but I am stuck on this one. I would love to use the one that has the drivers on the dvd. But, I will use any of them.

I am using the latest version of Ubuntu Mate. Bionic Beaver 18.04. The motherboard is an Asrock970m Pro3 (crap) CPU: FX-6350, not overclocked. (crap too, but it was sitting around). 8 gigs ram. Want to use this rig as a media server/file server.

In an semi-related issue, I have an Nvidia GTX760 in here and its not giving me any option to install the proprietary drivers from Nvidia.

Thanks again, any help is appreciated.

For the ASUS BCM43526 try:

In terminal...

sudo apt-get update
sudo apt-get install broadcom-sta-dkms

For the D-Link DWA-192:

In terminal...

sudo apt-get install build-essential git
sudo git clone 

create dkms.conf in the rt8814au folder, and add these lines...

# rtl8814AU-4.3.21_17997.20160531
#
#
PACKAGE_NAME="rtl8814au"
PACKAGE_VERSION="4.3.21_17997.20160531"
MAKE[0]="'make' all KVER=${kernelver}"
BUILT_MODULE_NAME[0]="8814au"
DEST_MODULE_LOCATION[0]="/updates/dkms"
AUTOINSTALL="YES"
REMAKE_INITRD="NO"

then...

sudo cp -r rtl8814au /usr/src/rtl8814au-4.3.21
sudo dkms add rtl8814au/4.3.21
sudo dkms build rtl8814au/4.3.21
sudo dkms install rtl8814au/4.3.21
dkms status

note: you may have to adjust the version numbers if a newer release exists

With a temporary working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt-get update
sudo apt-get install build-essential git
git clone
cd rtl8814au
make
sudo make installfw
sudo insmod rtl8814au.ko

Please tell us if the device is now working as I will have further instructions to add in an edit.

EDIT: We see this message in your make:

Makefile:976: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"

Please do:

sudo apt update
sudo apt install libelf-dev

A series of dependencies will also be installed. Follow with:

cd rtl8814au
make clean
make
sudo insmod rtl8814au.ko 

Post any errors.
