Hello,

Booting Liquorix 4.20.0-5.2 :
Network is operational locally but route table is empty and other computers are not reachable.
I.e : pinging local address or loopback is OK, pinging or trying to resolve a name is not OK.

Booting Liquorix 4.20.0-5.1 :
Everything's fine.

Found this in logs :

You want to show: inxi -xxxiz
That will give more useful information about your actual interfaces etc. The -z will hide IP and mac addresses.

[37693.393826] usb 3-4: new SuperSpeed Gen 1 USB device number 4 using xhci_hcd

Booting Windows on the same computer is fine, so I exclude a hardware fault.
I reckon a driver is the culprit.

It seems that a lot of people have problems with the r8169 driver that you're using. All I can recommend is try another ethernet cable or buy a ethernet card to replace your onboard.

Looking at your motherboard online, you have plenty of expansion ports to pick from, both PCI and PCIe: https://www.asus.com/Motherboards/Z97K/websites/global/products/3wvOh4rV4y53ywKS/img/hp/overview/overview.png

I personally would use the older PCI ports so you can reserve your PCIe ports for newer hardware. Here's a decent one made by Intel on Newegg: https://www.newegg.com/Product/Product.aspx?Item=9SIA4A08GT2322

Not the answer you probably wanted to hear, but swiftly replacing hardware that doesn't work well with linux is the best choice to solving these problems if you can afford it.

Just to add, for future reference :

Reboot -> network doesn't work
Cold boot -> network works ...

See https://bugzilla.redhat.com/show_bug.cgi?id=1650984 -- 2019-02-01 02:20:28 UTC , same thing here.
