Using Debian

WiFi works great, and I connect via wpa_supplicant. However, Ethernet does not work when trying to use it to ping or access the internet. The link is detected by ethtool as shown below.

My ip link response

will@debian:~$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether d0:67:e5:0c:05:37 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether 38:59:f9:73:36:cc brd ff:ff:ff:ff:ff:ff

my /etc/network/interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
#auto lo
#iface lo inet loopback

#enp3s0 is broken, but ethernet cable is plugged in
auto enp3s0
iface enp3s0 inet dhcp
gateway 192.168.0.1

# wifi works fine
auto wlp2s0
iface wlp2s0 inet dhcp
        wpa-ssid "xxx"
        wpa-psk "yyy"

This computer seems to only support 2.4ghz connections, so ethernet is pretty much my only viable option. Help would be appreciated!

Ok, so I can't add my ethtool response because discord is a bunch of jackasses and want me to pay to send a 500 character message. Here it is:

note that ping -I enp3s0 x.com also hangs up on the following message:

lspci -v preferably

what does (as root)dmesg | grep r8169 show?

jolly stream
#

@lean valve Try to pacman -Sy r8168

#

Or if you are using lts kernel pacman -Sy r8168-lts

#

Then :

# dracut --hostonly --force
# grub-mkconfig -o /boot/grub/grub.cfg
# reboot
#

(As root)

karmic shard
#

why -Sy? aren't partial upgrades not recommended?
-S should be fine I think. or -Syu
