no wifi adapter found ubuntu 20.05 in hp pavilion dv5

I have this old hp pavilion dv5 in which I've been running ubuntu 20.04 (not dual boot) without issues until yesterday.

Suddenly, the wifi stopped working and in the wifi settings it said 'no wifi adapter found'. Since I had the same issue when I first installed ubuntu, I thought it was an easy fix. I connected via ethernet and tried to follow the steps detailed here in the last gray box of the accepted solution. I thought that was how I fixed the problem originally but now it doesn't work since the repo https://github.com/lwfinger/rtlwifi_new.git no longer exists?

I have searched for other solutions but all seem to rely on said repo. Is there any other way to fix this problem?

Edit: Results from running lspci -nnk | grep -iA3 net in the terminal:

Does this answer your question? [Installing Broadcom Wireless Drivers](https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers) There is no Ubuntu 20.05.

Try `sudo apt update && sudo apt install --reinstall bcmwl-kernel-source` Then reboot

The correct command will be `sudo apt get purge bcmwl-kernel-source`. This adapter isn't properly supported by `wl`.

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.
