Note to self: make sure that the router is also set to reserve the static IP address. Once I updated the router (which I had forgotten to do), everything worked like a charm.

While Googling, I came across a few instances of others suffering with the same problem as me only to discover their ethernet cables weren't working, or something equally trivial. Hah! What idiots! Surely that's the first thing you check! ... Well, it turns out the power cable had ever-so-slightly slipped out of my network switch. I shall hang my head in ...

Put your /etc/NetworkManager/NetworkManager.conf file back the way it was - you'll just break Network Manager for no reason. Also remove the eth0 entry from /etc/network/interfaces because Network Manager is managing it. Your Ethernet card is definitely not disabled, so try: sudo ifconfig eth0 up sudo dhclient And see if you get an address assigned that ...

You need to install libnl-3-200_3.2.21-1_amd64.deb, not libnl-3-200-dbg_3.2.21-1_amd64.deb (note the additional -dbg) to perform the recommended fix. Please verify that you downloaded the correct package files, delete unrequired package files, and try again.

I had this issue with a VMware guest. The root cause is that I had the trusty-proposed repository enabled. I personally won't do that again. My resolution was to re-install. An option I took as it was a test virtual. As I understand it, a fix for a physical machine would be to sneakernet across the previous deb files to roll back the upgrade that broke ...

Ubuntu just had a major glitch. One of the last updated caused you & me and probably many others to stay disconnected because network-manager is crashing.

thank . you . so . much :) this was driving me bonkers! Note, this worked for me on Ubuntu 14.04. The indicators seemed to disappear after a routine system update. However, in my case, I did not need to sudo apt-add-repository ppa:jconti/gnome3 -y. The steps of removing items from the panel, and then doing "add to panel" worked for me. I also did sudo ...

The obvious mistake you made was mixing you mount point with the name of your block device. You can't do: sudo cp /etc/resolv.conf /sda2/etc/resolv.conf because /sda2 is non-existing directory. Earlier you did: sudo mount /dev/sda2 /mnt and /mnt (not /sda2) is the right directory for your copy operations. So do: sudo cp /etc/resolv.conf ...

Edit your NetworkManager.conf file.

The easiest way is to setup your router the way that 2.4 and 5 GHz radio interfaces have different SSID (network name). Then you will just choose the right SSID in Network Manager.

I don't know what wireless card you have in your computer.. or what router you have, but some of the latest BT routers (and probably others) are using new encryption protocols that some older wireless cards/software simply don't support. you may be able to change the encryption system in your router by logging in using a wired connection, and then opting for ...

A million thanks to this question here the problem is a bug in libnl package (see here for details ). I do not claim any credit for this answer.

I have the same issue. Seems that a recent update is the cause. Lots of messages in the syslog for network-manager being killed by segv (segmentation fault) signal. I believe the update for network manager has a segmentation violation bug somewhere. I managed to resolve my issue using the advice given by Paul Iulian. The link in his post does not work, so I ...

Update to network-manager 0.9.8.8-0ubuntu7.2, and reboot. Hot workaround: using manual network settings over sudo nano /etc/network/interfaces Working workaround! Downgrade some libraries: sudo apt-get install libnl-3-200=3.2.21-1 libnl-route-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1

Networks are re-checked automatically. You do not need to press anything. You can wait for some seconds to see a new network. To re-check immidiately you do not need to restart Network Manager. You can click "Disable Wi-Fi" and "Enable Wi-Fi", if you are so impatient.
