nothing

enp5s0 has static ip 192.168.0.10
wlp0s20u7 is DHCP

[alamahant]

Either configure your eth iface to NOT have a default gateway assigned to it, or the wlan iface.
You generally should not have two default gateways assigned in the same lan.
Ideally disable one of them.
As for the no internet after hibernate issue,just try to use an elogind script as in the above link with something like:

Code: Select all

rc-service net.<iface> restart

or systemd or NM equivalent.

Code: Select all

default via 192.168.0.1 dev enp5s0 proto static 
default via 192.168.0.1 dev enp5s0 proto dhcp src 192.168.0.221 metric 1002

This looks like a double configuration of both static and DHCP.

If you want pure static, then the DHCP client daemon should be configured to ignore this interface.

This looks like a double configuration of both static and DHCP.

If you want pure static, then the DHCP client daemon should be configured to ignore this interface.

That was the clue.

I had following in file /etc/systemd/network/70-static.network

Code: Select all

[Match]
Name=enp5s0

[Network]
Address=192.168.0.10
Gateway=192.168.0.1
DNS=192.168.0.1

Removed this file.

added following to /etc/dhcpcd.conf

Code: Select all

interface enp5s0
static ip_address=192.168.0.10
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

Code: Select all

ip route

Code: Select all

default via 192.168.0.1 dev enp5s0 src 192.168.0.10 metric 1002 
default via 192.168.0.1 dev wlp0s20u7 proto dhcp src 192.168.0.102 metric 3005 
192.168.0.0/24 dev enp5s0 proto dhcp scope link src 192.168.0.10 metric 1002 
192.168.0.0/24 dev wlp0s20u7 proto dhcp scope link src 192.168.0.102 metric 3005

And hibernation problem is solved.

Thanks a lot grknight
