Due to recent hardware network issues I'd like my eth1 (motherboard network) to serve as a backup to my main network connection eth0 (NIC) and can't seem to get it right.

 

I've assigned my Unraid a static IP locally to help with bookmarks etc. But when I disconnect the eth0 cable I can never connect. I've looked but can't seem to find the settings I need to change. Any advice welcome.

Add eth1 to bonding members on eth0

Amazing, thank you

Okay so despite adding eth1 to bonding members eth0 I still have been losing my internet connection. I have also upgraded to the latest Unraid Beta.

 

I keep getting

 

Nov 25 22:16:03 Unraid kernel: r8169 0000:03:00.0 eth1: rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100).
Nov 25 22:16:14 Unraid kernel: r8169 0000:03:00.0 eth1: rtl_txcfg_empty_cond == 0 (loop: 42, delay: 100).

 

r8169 is eth1 so I thought that if eth0 is fine it should be okay.

 

It always seems to happen around 9pm at night, I'd been using it all day. And when I reopen my laptop where I'm logged into my Unraid dashboard and/or the Windows VM running on it it tends to, but not always, fix itself.

 

The Intel NIC seemed to be okay but after an error I thought that bonding the flakey r8169 motherboard device to eth0 it would mean that if one fell out then the other would kick in and I'd have a stable connection.

 

Any thoughts?

Okay so the mystery deepens as now I am getting spammed by these messgaes several times per minute
