Public bug reported:
The network card inside my laptop will stop detecting connections after a while
whithout having an ethernet cable inserted. in the gnome settings, it will show
that there is no cable conected. The lights on the port on the laptop won't
light up, but those on the port of the switch will light up when the laptop is
connected. I got this problem in kernel 5.15, 5.19 and 6.2(ubuntu 23.04
upgraded from 22.04). the problem won't occur if i use a usb NIC.
I wasn't able to find a true cause for this, but right after reboot, the cable
will work with the integrated card.
this is returned when doing ifconfig. as you can see, the card
transfered some data before not working.
