gnome NetworkManager doesn't see any wired or wireless network

[Grzegorz Galezowski]

It;s this way from yesterday. I have both wireless network (wifi, intel 3945) and wired connection with another computer which serves as a gate. The wired connection works which I can confirm by pinging any site. The wireless connection seems to be configured properly, because when I enter System->Preferences->Network, I can see all of wireless networks near me in network selector. The problem is, Gnome Network Manager doesn't see any connection at all. when I click on it, it gives me only the "No network devices found" message (sorry if message contents are inaccurate, I'm running Ubuntu in Polish). I can't really think of any steps to reproduce this bug (I didn't change anything in configuration in the meantime), but its effect is permanent, so if you want any additional info, just instruct me how to gather it and I will.

I had exactly the same problem after upgrading to network-manager 0.6.4-6ubuntu5 as part of a larger upgrade this morning -- nm-applet reported that no network interfaces were available, and no wireless connection was made. (Using Proxim PCMCIA G card, Atheros HAL.)

The wired connection worked correctly.

I fixed the problem on my system by downloading the packages comprising 0.6.4-6ubuntu4 and performing a force-downgrade, i.e.:

$ ls *.deb
libnm-glib0_0.6.4-6ubuntu4_i386.deb
libnm-glib-dev_0.6.4-6ubuntu4_i386.deb
libnm-util0_0.6.4-6ubuntu4_i386.deb
libnm-util-dev_0.6.4-6ubuntu4_i386.deb
network-manager_0.6.4-6ubuntu4_i386.deb
network-manager-dev_0.6.4-6ubuntu4_i386.deb
network-manager-gnome_0.6.4-6ubuntu4_i386.deb
$ dpkg --install --force-downgrade *.deb

The same here. Fortunately I had older versions of debs in /var/cache! Interestingly I had downgraded network-manager and network-manager-gnome packages only, so it looks like the problem is with them and not libnm.

[Stéphane Graber (stgraber)]

NetworkManager seems to be disabled if /etc/network/interfaces has any settings set for one of the interfaces.
I think it's to be able to set custom settings but in some case can become a problem (just like now after an update).
You can fix it by cleaning up your /etc/network/interfaces, removing everything but the two "lo" lines.

Incountered something similar while testing Gutsy Gibon Tribe 3.

Nm didn't see any network device, although I could connect to the internet and an ifconfig showed me a correctly setup eth0.

Then 10 minutes later I found my device.

Here too! Tribe 3

Carroarmato0 and zeddock - please open a new bug report instead of commenting on a bug that is a duplicate of another bug. Thanks!
