Connectivity issues after recent update

Since the recent update (a few days ago) my Ascii system looses network connectivity pretty much instantly after boot. I can re-establish a network connection using the wcid widget, but before said update, my network was always connected to my LAN. After a period of inactivity, the network disconnects again, despite my settings (in wcid) to re-establish a connection when lost. The system has a Gigibyte F2A88XM-D3H mainboard, with a Realtec RTL8111/8168/8411 Gbit network chipset, no wireless.

/etc/network/interfaces:

# 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

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto

/etc/network/NetworkManager.conf:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

Hope this can be resolved quickly, as it's getting old now :-\

you have both wicd and NetworkManager installed? maybe try removing one of those..
also the latter should be "/etc/NetworkManager/NetworkManager.conf", right?

Re: Connectivity issues after recent update

Yup, my bad, it's indeed in /etc/networkmanager.

Oddly enough, the issues I had even yesterday don't seem to manifest themselves today. However, I doubt removing either of the managers as you suggest would solve it, as it has worked flawlessly before with both installed. But thx for the suggestion anyway, should it re-occur I might ditch wcid to see if there's a conflict between the two.

Re: Connectivity issues after recent update

The other standard suggestion in this case is to either use one network manager or configure in /etc/network/interfaces. Not both. If it's not a laptop that travels around to different networks, you may as well ditch both network managers.

Re: Connectivity issues after recent update

Note that eth0 is being controlled by ifupdown rather than NetworkManager: https://wiki.debian.org/NetworkManager# … _Unmanaged

So try replacing "allow-hotplug eth0" with "auto eth0". Or use NetworkManager instead of ifupdown.

Don't bother with wicd, it's crap.

Re: Connectivity issues after recent update

Thx gentlemen. On reflection, I have purged both network managers from my system, adjusted /etc/network/interfaces as suggested and will await the next boot for results. This machine is indeed my regular desktop, which is on for most of the day when I'm home.

I have good success with wicd. I have used NetworkManager before and it was OK. I think I even successfully used NM to connect with those complicated auth schemes like EAP v2 (that AD RADIUS auth stuff) but that was back in my Fedora days.
While /etc/network/interfaces is fine with me, and I prefered the old Red Hat /etc/sysconfig/network-scripts because it was shell scripts, I have found wicd-cli and wicd-gtk quite sufficient!

What do you dislike about wicd?

It's written in Python2, which is now officially dead[1], and it hasn't been updated for four years[2].

Re: Connectivity issues after recent update

wicd is already being ported to python3, and there is a -buggy- python3 version in debian experimental , so it's got a future...
