Ubuntu 22.10 RTL8821CE no longer shows up in additional drivers

Today I upgraded to 22.10. I know it is kind of a rash decision. I should've waited longer. But this purged my WI-fi driver(RTL8821CE) and now it doesn't show up in the additional drivers like in 22.04, so I don't have Wi-fi connection. I'm using my phone's USB thetering. I enabled the 22.04 community repo in Other Software but it didn't help. Any other ideas? What is the best place where I can request to be included in the new repos?

Edit: Wi-fi never worked for me out of the box, even in newest kernel with Arch. Only on Ubuntu (and derivatives) when I enable the RTL8821CE(dkms) in the additional drivers.

lspci -knn | grep Net -A3; rfkill list output:

Support for RTL8821CE was added to the Linux kernel in version 5.9. You should no longer need any special packages for that hardware (if that's really what you have). Troubleshoot your hardware normally, not assuming a repo is the issue. See https://askubuntu.com/questions/1370462/how-to-troubleshoot-wifi

Had the same problem this evening. Installing the driver manually worked for me. See here

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.
