Tried to install Linksys ac1200 and failed in the procedures described here [duplicate]

I am running Ubuntu 20.04 and I bought a Linksys AC1200 wireless adapter without doing enough research, figuring I could get it to work. I have followed the instructions at the following link, as well as a few permutations thereof, all to no avail.

LinkSys AC1200 Wireless-AC USB adapter install

lsusb shows the adapter plugged into my usb. But nothing for wireless shows up when I use lshw -C network, only for my ethernet connection. I don't get any errors during the make or the install, but nothing seems to happen. I get no prompt, nor does the little network dash pop up. I'm not sure what else to try. Can anyone help? I can provide copies of whatever commands are necessary to diagnose the problem.

EDIT, output from lsusb: The device seems to be
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 003: ID 13b1:0045 Linksys WUSB6300 V2
Bus 005 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I'm pretty sure the adapter is
Bus 005 Device 003: ID 13b1:0045 Linksys WUSB6300 V2

as it appears when I plug in the device and disappears when I remove it.


Solution 1:

13b1:0045 Linksys WUSB6300 V2

The driver for your device is 88x2bu. Let’s build it.

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

git clone https://github.com/morrownr/88x2bu.git
cd 88x2bu
sudo ./install-driver.sh 

Reboot. Your wireless should now be working.

NOTE: Since you refer in your question to another attempted driver installation, I assume that the prerequisites git, dkms, build-essential and linux-headers are already installed.
