I installed ubuntu 20.04.6 on my thinkpad X1 carbon gen11 and the wifi reported "No Wi-Fi' adaptor found". The wifi card is Intel(R) Wi-Fi 6E AX211, and it works on my windows system. Since the computer have no port for network cable, my ubuntu just have no access to internet at all. I checked the kernal requirement for my wifi card, and 20.04 meet the requirement.
I also shut down the fast boot, security boot, security chip(TPM) and reinstalled the ubuntu, but it didn't work.
What's more, I have viewed some previous post. My situation is almost the same with a previous post: No Wi-Fi adapter found ubuntu 20.04 lenovo thinkpad x1 carbon . In this post, the issue is solved by upgrading to ubuntu 24.04. But I need to run ros on my computer, and the latest available ubuntu version for ros is 20.04. So I can not simply switch to the latest ubuntu.
Another post: Ubuntu 20.04 No Wifi Adapter Found. Lenovo Ideapad Realtek . is also related to lenovo. Not specificly the same device, nor did the same wifi card. The comment for the aforementioned post advise to down dependencies. But my ubuntu can not connect to internet and I don't know how to do. My result for running lshw -C network and lspci are as followed:

I got the code by OCR, so it might not be very accurate. Is there any method to fix the wifi issue for my computer?
