Hi I have a question in this problem.
My desktop moniter resolution is weird, so I fixed it once, and the Wi-Fi is disconnected and it says "NO Wi-Fi adapter found." First of all, when I tried to install the driver, I learned through Google that firmware and modules must be installed together. But there was one problem. The firmware appears to be installed, but the command does not work when you try to load the module. What should I do in this situation?
I checked the https://community.intel.com/t5/Wireless/AX200-unable-to-detect-WiFi-Network/m-p/1225944 provided by Intel, I found 46,48,50,53,55,59,62,63,66,67,68,71,72,73.ucode exists in the /lib/firmware file, but i didn't use the 'mokutil' method. Is it okay if I try this method?
Or I looked for other ideas.
When I checked $dpkg -l | grep linux-modules , there are currently modules that are the same as the Linuxkernel version. Then, isn't it installed? However, there was no extra module. So, is this the problem?
