I tried this: I turned off wireless network. I went in Network Manager, modified my cabled network configuration from DHCP to fixed, entered an IP adress and everything else is needed to make my wired network work. I turned detached my eth0 cable, turned on wirelss network, and canceled the wired configuration I had entered previously. I turned off wireless network again and tried to plug in a network cable in my eth0 port. I had the problem I reported at the beginning of this bug. I took a look at the /etc/NetworkManager/NetworkManager.conf file and this is what is in it now:
[main] plugins=ifupdown,keyfile dns=dnsmasq #no-auto-default=C8:0A:A9:11:DE:0A, no-auto-default=C8:0A:A9:11:DE:0A, [ifupdown] managed=false As you can see there is another line "no-auto-default=C8:0A:A9:11:DE:0A," that is not commented. I think that, if you configure a wired network without DHCP in Network Manager and then cancel it the no-auto-default line remains in the configuration file and is not cancelled, so the next time you try to use DHCP you are not able to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059065 Title: Network Manager does not connect the network adapter to a network with a DHCP server automatically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1059065/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
