Wired connection doesn't work after suspend.

[Jose Mourinho]

Wired connection doesn't connect after suspending PC and starting it back. The system is Ubuntu 16.04 LTS.

Output of lspci command:

And output of lspci -k | grep -iA3 ethernet (I don't know what does this command show but I have come across this command when I was looking for the answer in google) command:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 02)
    Subsystem: ASRock Incorporation Motherboard (one of many)
    Kernel driver in use: r8169
    Kernel modules: r8169`

Edit on Sep 9 2017, Sat: I tried to install r8168 driver from realtek's site. First, I followed the manual instructions in this site: https://unixblogger.com/2016/08/11/how-to-get-your-realtek-rtl8111rtl8168-working-updated-guide/

I tried to install dependencies by entering the code into terminal:

sudo apt-get install build-essential linux-headers-$(uname -r)

and then I downloaded the driver from Realtek's site: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#2

I downloaded the version which states Linux driver for kernel up to 4.7. I don't exactly if that is the case, if that one is causing me the problems.

Then I blacklisted my already installed and working r8169 driver by this code:

user@linux:~$ sudo sh -c 'echo blacklist r8169 >> /etc/modprobe.d/blacklist.conf'

Then I untarred the archive by this code: tar xfvj 0009-r8168-8.044.02.tar.bz2

which showed me the following output:

r8168-8.044.02/

r8168-8.044.02/src/rtl_eeprom.c
r8168-8.044.02/src/rtl_eeprom.h

After that I got into that folder r8168-8.044.02/ and compiled the script autorun.sh sudo ./autorun.shwhich showed me the following output on terminal:

Check old driver and unload it.
rmmod r8169

Completed.

Then I run this code: lsmod | grep r8168 which output: r8168 499712 0

Then I run sudo ethtool -i enp2s0.

After that I suspended my PC and reopened it back, but it had the same problem, it did not connect to Wired connection after suspension. I had reboot it to get working Ethernet connection. After rebooting I tried to install it automatically rather than manually, so I edited /etc/apt/sources.list, I changed xenial main restricted to xenial main restricted universe. Then I sudo apt-get update, then I sudo apt-get install r8168-dkms. However, those things also did not help, when I suspended my PC. So, I had to reboot again to get internet connection.

After rebooting I followed some of the instructions in this site: https://nosemaj.org/hardy-r8168.

I run:

sudo bash

then rmmod r8169 which output rmmod: ERROR: Module r8169 is not currently loaded.

then make clean which output:

make -C src/ clean
make[1]: Entering directory '/home/garakchy/my_stuff_002/drivers_I_downloaded/r8168-8.044.02/src'

then make modules which output:

then make install etc. After all, I suspended my PC and reopened it back, it totally crashed and stopped working at all, let alone the not working Ethernet connection. My PC got stuck. I reboot. After rebooting my PC temporarily working in good condition, but I wanted to go back to r8169 driver, which was installed default. So, I changed modprobe.d/blacklist.conf, I deleted r8169 there and wrote r8168 instead.

Output of sudo lshw -class network command:

It shows r8168 as a driver still, even if I had blacklisted it.

Here are some other information that I thought would be useful: http://paste.ubuntu.com/25497742/
