I have a newer laptop with an older version of Ubuntu. The older version is required because it supports ROS1, and newer versions do not. However, my system doesn't recognize the wifi-adapter, and it doesn't seem to load the drivers properly. Here are my system specs:
- Ubuntu version: 20.04
- LTS Processor: 13th Gen Intel(R) Core(TM) i9-13900H
- Network controller: Intel Corporation Raptor Lake PCH CNVi WiFi (rev 01)
- Kernel version: 5.15.0-124-generic
Running ip a the wifi-adapter is absent. Running lspci | grep Network I get the information provided above.
From what I have found in my search so far, it suggests that the necessary drivers for my wifi-adapter might not be compatible with such an old kernel version. However, I am not 100% certain of that conclusion, but I have seen some posts saying that kernel version 6.0+ is required.
I tried to find a mainline kernel version here, but all of the builds for Intel processors (i386 builds) seem to have failed, so there are no .deb files? Can I even update to newer kernels for 20.04?
My knowledge of linux in general is quite intermediate, so please take that into account.
I appreciate any help to solve this issue.
