I installed mac os catalina on my thinkpad t450s 2 days ago but wifi is not working even with kexts

so I installed mac os catalina on my thinkpad and for some reason there's no option for wifi anywhere, not in system preferences, not even on the topbar. Do I have to use android tether rn. I think it doesnt support my card which I havent check for the model and Idk how to do that on mac os yet. Is there anyway for me to fix this or do I have to down/upgrade mac os or sth? Please help and thankyou sooo much T^T
