Wired connection problem after upgrade to 4.15.0-33

[camoltoni]

My wired connection does not working since update to Linux 4.15.0-33
Everything is fine if boot with the Linux 4.15.0-32.
I don't no how to start
Thanks

I don't no how to start

Well, a start would be to describe your hardware.

Could you post the output of inxi -F in a konsole? Use sudo apt install inxi if you don't already have inxi.

Sorry for the delay, this is the output of inxi -F

mmmm... no wireless device is shown.
What does "rfkill list" give you?

Google shows problems are reported using the r8169 driver with the 8168 controller; to the point that someone is maintaining a driver on github: fintecheando/r8168. The fact that this has been updated last month specifically mentioning kernel 4.15, and there are reports of success with this, suggests that it is relevant to your problem. However, that you run successfully with a slightly older 4.15 doesn't fit well.

The installation instructions look scary; if you're not familiar with building drivers from github, you might want to just stay on the older kernel for a while. I can see an immediate flaw in those instructions: the two lines:

	Unpack the tarball :
		# tar vjxf r8168-8.aaa.bb.tar.bz2
     Change to the directory:
		# cd r8168-8.aaa.bb

don't make any sense to me for something on github. I think they should be:

git clone https://github.com/fintecheando/r8168.git
cd r8168

But the requirement for "Compiler/binutils for kernel compilation" is beyond my comfort zone, so I imagine yours too. Perhaps there are other members of KFN who'd be more familiar with compiling drivers; I last did this about 10 years ago.

Thanks, I think I'll wait until a new release

strange ,,I have the same network adapter in my box and it seems to just fine with the 4.15.0-33 kernel

but this is in my xenial install will check the bionic in a bit .

VINNY

EDIT" yup works fine in the bionic install as well

dose lspci -k show a kernel module as well as driver ?
