in spite of following exactly the instructions in the following answer:

https://askubuntu.com/a/642812

, although the driver appears to be installed and running according to modinfo, lshw -C network and nmcli show no Wifi device.

I am running Ubuntu 18.04, kernel version 5.4.0-77-generic, on a Dell Precision 5820 Tower Workstation.

lsusb shows:

dkms status shows:

rtl88x2bu, 5.8.7.1, 5.4.0-77-generic, x86_64: installed

Any idea what to check or try next to determine why this driver doesn't seem to be working as recommended?

EDIT #1 modinfo on rtl88x2bu shows:

(base) ➜  rtl8812AU_8821AU_linux git:(master) ✗ sudo modinfo rtl88x2bu | grep 0045
modinfo: ERROR: Module rtl88x2bu not found.

The driver for your 13b1:0045 device is 88x2bu, not rtl8812au. Please edit your question to show the result of the terminal command: `modinfo rtl88x2bu | grep 0045` Possibly a duplicate: https://askubuntu.com/questions/1350238/common-method-for-installing-linksys-ac1200-usb-wireless-router-ineffective Welcome to Ask Ubuntu.

@chili555 Now after following exactly the instructions you provided at https://askubuntu.com/questions/1350238/common-method-for-installing-linksys-ac1200-usb-wireless-router-ineffective, `modinfo 88x2bu | grep 0045` indicates that `0045` is located in the `modinfo` output, and my wireless now works!

@chili555 The "golden ticket" in this case proved to be installing the driver from `git clone https://github.com/morrownr/88x2bu-20210702`. Last night, I tried installing the driver at https://github.com/cilynx/rtl88x2bu, but no luck :(. Is there some Wiki documentation for your procedure, which I now believe should be enshrined in gold? ;)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
