Ethernet driver not recognized

Post by pips3 » Wed Oct 10, 2018 2:41 pm

Hi all.

I've installed Linux Mint 19 Tara on a new HP Pavilion 15 laptop.

I'm having a weird problem with the ethernet connection. Sometimes it works, others don't. At the beginning it was functioning well but wireless connection wasn't, so I manually installed a drive and it is now working. The ethernet connection is not recognized now, and the weird thing is that it is not working in Windows 10 either, tho yesterday I had the same problem and a restart solved it but now it didn't worked.

"inxi -Fxz" only lists the Wireless adapter (see below). I checked the BIOS and there is no option for disabling/enabling the ethernet connection. I've also updated the BIOS but nothing works.

Have anyone encountered a similar problem? Thanks.
