This is with an up-to-date Precise install, and on this occasion when ISO testing. I doubt that it has to do with hardware, because it's happened on two completely different machines (Asus EeePC 900 with Atheros L2 chip and a desktop machine with r8169). When this happens, the computer is assigned an IP number, an internet connection exists and I can ping various websites plus my router by using the IP number. Website names of course don't get resolved. The problem is solved (in the short term) by entering "sudo dhclient" in a terminal. ~$ sudo dhclient RTNETLINK answers: File exists Before issuing this command, /etc/resolv.conf reads: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.0.1 search lan After issuing the command, /etc/resolv.conf reads: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 192.168.1.254 nameserver 127.0.0.1 search lan ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: network-manager 0.9.3.995+git201203152001.04b2a74-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-20.32-generic-pae 3.2.12 Uname: Linux 3.2.0-20-generic-pae i686 ApportVersion: 1.95-0ubuntu1 Architecture: i386 CRDA: Error: [Errno 2] No such file or directory Date: Sun Mar 25 01:51:16 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Alpha i386 (20120324.1) IwConfig: lo no wireless extensions. eth0 no wireless extensions.
