I'm having issues with recognizing my external Wifi adapter. I used the exact same model of adapter(Archer T3U Plus, AC1300) before and installed the aircrack drivers as directed in this answered question. After installing the drivers and using the sudo modprobe 88XXau command, the green LED lit up and I was able to connect to networks and browse with zero issues. However after losing said device, I replaced it with an identical model. As the drivers had already been installed, I expected it to work out of the box. But it didn't. I tried using the modprobe command again and it didn't work. I then used sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all to remove the aircrack drivers and install them again to no avail. I've tried rebooting several times, running modprobe again and still nothing.

lsusb shows this:

The device also works perfectly in Windows so it's probably not a hardware issue.

Any input is appreciated, thanks in advance.

Your new device isn’t an rtl88XXau, but a rtl8822bu. Fortunately, [this answer from last year](https://askubuntu.com/a/1256330/1222991) will get you running quickly

Try :

git clone https://github.com/RinCat/RTL88x2BU-Linux-Driver.git
cd RTL88x2BU-Linux-Driver/
make
sudo make install
sudo modprobe 88x2bu

After each kernel update, you must recompile:

cd ~/RTL88x2BU-Linux-Driver/
make clean
git pull
make
sudo make install
sudo modprobe 88x2bu

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.
