Another workaround for those who don't want to use the network manager: I set the method of my wlan interface to manual in /etc/network/interfaces: iface wlan1 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf post-up /etc/network/dhclient-wrapper & post-down [ -f /var/run/dhclient.wlan1.pid ] && kill `cat /var/run/dhclient.wlan1.pid` To get an IP adress from an dhcp server I wrote the attached script dhclient-wrapper. It calls the dhclient3 with parameter -1. If the dhclient cannot obtain an address it exits with code 2. In this case I deactivate the wlan interface in the script. However the & makes the script running in the background preventing Ubuntu from hanging while it boots up. The post-down statement is for killing the dhclient programm if the interface is deactivated. ** Attachment added: "Script for calling dhclient in the background and deactivating the interface if no dhcp server was found" http://launchpadlibrarian.net/20880392/dhclient-wrapper -- Ubuntu 8.10 booting hangs for a while on "configuring network interfaces" on iwl3945 and iwl4965 https://bugs.launchpad.net/bugs/293023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You are right, if I delete my /etc/network/interfaces there is no delay on booting. But this is not a solution because you need the file for configuring the network interfaces. I don't want to use the network manager and I think the Ubuntu network should not depend on it. For me the basic configuration with /etc/network/interfaces works much better than the network manager. (Multiple default routes, proper handling of access point selection with wpa_supplicant, even with hidden networks). So deleting the file and using the network manager would be a workaround but no fix for this bug. -- Ubuntu 8.10 booting hangs for a while on "configuring network interfaces" on iwl3945 and iwl4965 https://bugs.launchpad.net/bugs/293023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think Adam is right. I don't understand it, too. It worked just fine under Ubuntu 8.04, so I am almost sure this is a bug! -- Ubuntu 8.10 booting hangs for a while on "configuring network interfaces" on iwl3945 and iwl4965 https://bugs.launchpad.net/bugs/293023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think setting to zero is not a good idea. I have configured a netbook with an atheros network card yesterday. After setting timeout to 5, I was not able to get an IP address so I had to increase the value to 10. As far as I have seen from the output, the network card was not ready in 5 seconds, so the first dhcp request was not successful and is waiting for some seconds like this: DHCPDISCOVER on wlan1 to 255.255.255.255 port 67 interval 6 No DHCPOFFERS received. If timeout is 5, no more discovers are made, instead the dhcplient cancels. After setting timeout to 10 it worked because the second request has been answered. -- Ubuntu 8.10 booting hangs for a while on "configuring network interfaces" on iwl3945 and iwl4965 https://bugs.launchpad.net/bugs/293023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wow. You dhclient is definitly much faster than mine? What did you set the timeout value to? I set it to 5 (perhaps uncommenting it, too ;-) ) ** Attachment added: "intrepid-20081205-4.png" http://launchpadlibrarian.net/20233793/intrepid-20081205-4.png -- Ubuntu 8.10 booting hangs for a while on "configuring network interfaces" on iwl3945 and iwl4965 https://bugs.launchpad.net/bugs/293023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I set the timeout value to 5. After that, Ubuntu boots faster but I have still a delay for 20 seconds. It is better than one and a half minute but still annoying if sitting in the train and waiting for linux to come up. Maybe I will try it with the use of different runlevels (to disable network at startup).

I have the same issue. Ubuntu 8.10 hangs a while by "Configuring network devices..." if no configured wlan is reachable.

But the NM doesn't work for me so I don't want to use it. -- In Ubuntu 8.04 all works fine. If a network configured in wpa_supplicant.conf is in range Ubuntu boots just fast and fine.
