Answers to: gnome network manager versus /etc/network/interfaceshttp://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces<p>I need some troubleshooting help with a wireless network problem.</p> <p>I can connect wirelessly using /etc/network/interfaces. ifup wlan0 gets an address via dhcp and all works well. However, I have to click and disable the network manager trying to connect in order for this to work.</p> <p>If I let gnome network manager connect, it does not succeed. I am getting in daemon.log: NetworkManager: Device 'wlan0' IP6 addrconf timed out or failed.</p> <p>Interestingly, gnome network manager succeeds in connecting to public networks in coffee shops. This makes me think something is not properly set up at my home router.</p> <p>Any suggestions? Thanks!</p>enTue, 02 Aug 2011 15:18:36 -0400Comment by Ron on Matyas's questionhttp://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces#2655<p>Your router probably does not support ipv6 (not many do right now), not an answer, just a comment. To use ipv6, you'll need a newer/different router (or firmware). You can also do 6-to-4 tunneling through a free service if need be.</p>RonTue, 02 Aug 2011 15:18:36 -0400http://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces#2655Answer by vorbotehttp://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces/2654<p>I'm under the impression that you may be going the wrong way about it. If by gnome-network-manager you are refering to the gnome applet to control Network Manager, why are you using the ifupdown infrastructure at all? They conflict. Comment out the lines pertaining to wlan0 in /etc/network/interfaces and configure your connection with Network Manager applet. Simply select the network you want to connect to in the menu, give the password, store it if you want (it is optional) and let Network Manager do its thing.</p>vorboteTue, 02 Aug 2011 13:03:50 -0400http://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces/2654Comment by rfelsburg on Matyas's questionhttp://linuxexchange.org/questions/1117/gnome-network-manager-versus-etcnetworkinterfaces#2464<p>Please accept an answer so the question/answer can be finished.
