I have a usb wifi adapter that im using as a hotspot in my room , but it is not being recognized , eventhough it shows up in lsusb.

I should probably note that I installed a custom driver from github , wich worked fine untill I installed ubuntu 21.04.

lsusb output:

But when I look up the ethernet adapters with lshw -class network -short it just shows one , wich is the ethernet jack on my motherboard:

H/W path            Device      Class          Description
==========================================================
/0/100/1.3/0.2/1/0  enp4s0      network        RTL8111/8168/8411 P

I also couldnt figure out how to uninstall that driver or how to check if it is even still installed.

Unless this was a release upgrade (as opposed to fresh install) then whatever you installed before is obviously irrelevant and even with normal kernel updates, if the drivers weren't installed with DKMS, those drivers must be reinstalled. So, you may need to install that same driver again. https://askubuntu.com/questions/1018375/how-do-i-install-driver-for-rtl88x2bu

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.
