Laptop Wireless Interface Suddenly Quit Working

Hey guys,

I've been able to use NetCTL to connect to both my Ethernet networks as well as my wireless networks without too many major issues. Within the last week though, I suddenly lost access to wlo1 entirely and I have been unable to bring it back. I'm not sure if this happened after a system upgrade or not, but I was hoping someone either recently experienced the same thing, or if someone maybe knows what the issue could be with the provided information. I have made sure rfkill isn't blocking it and it doesn't appear that it is. When I enter ip a, nothing even shows up for my wireless interface, just the loopback and the Ethernet appear.

I've tried checking with lspci just to see if the card even shows up, and it does. This led me to find that it doesn't show a driver in use. I imagine this is a problem, but as I never experienced this before, I never paid attention to this output so I don't know if it just stopped using a driver or what the deal is. I can't imagine why the system would do that, but hopefully someone more intelligent than me will know.

I'll list the output of the relevant output from lspci and if you want any more information, please feel free to ask.
