Wifi card not detected meditatek mt7921e on ubuntu 22.04

pn flag

I'm dual booting Ubuntu 22.04 and Windows 11. My wifi card is Mediatek mt7921e. Laptop model: Asus TUF Gaming f15.

Ubuntu sometimes can't detect my wifi interface. This happens totally randomly. When that happens, the output of sudo lshw -C network and sudo lspci doesn't show any output for my wifi card. Plus from the settings also the PCI Wifi option completely disappears. I have done several reinstalls of ubuntu but the problem persists. The problem also persists when I boot into Windows where it says: Currently this hardware device is not connected to the computer. (Code 45)

Also, in the times when wifi does get connected, my entire screen freezes after some time, nothing works and the only option is to manually power off. During shutdown, I keep getting the following messages (copied from logs):

I tried using a distro with a newer kernel (6.2) but the same issue is persisting. The driver isn't blacklisted. I have checked /etc/modprobe.d/blacklist.conf.

As one can see the mediatek card is not detected. I wish I could the output of these commands when my card was detected but unfortunately my card isn't being detected right now.

Some people have also suggested to hold the power button for 60s while booting that also isn't working. The problem started around October 2022. I have tried disabling fast startup and Secure Boot but my wifi card still isn't detected.

Since this is happening in both Windows and Ubuntu it appears you have defective or failing hardware.
I sit in a Tesla and translated this thread with Ai:

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.
