Good time of day to you kind people.
I started having problems with my LAN connection. It’s a backup lenovo machine and everything was working swimmingly until I tried upgrading my wifi card. Turns out this model only supports certain kind of wireless modules and to use any other outside the list I have to change refirm bios and etc.
Long story short. After removing it altogether and going for an external wifi module I just decided to use hardwired connection and manually install the driver since there isn’t one for Linux separately.
When I plug in the cable it doesn’t detect the connection. lspci lists my card fine. When I do the same on windows, there is no issue. When I boot into live distro there is no issue.
Don’t really know what is it.
