I too am unable to use networking with Hardy (kernel version 2-6-24-17) on my machine which features an Asrock AliveDual-eSATA2 motherboard with a Realtek RTL8111B/RTL8111C on board LAN controller.
However this hardware works fine if I boot from either a Feisty CD, a Gutsy CD or a Knoppix 5.1 CD. After this experimentation I tried installing Gutsy 32bit and this worked o.k. After this I installed Gutsy 64 bit, which again worked o.k., which I followed by doing a distribution upgrade to Hardy. Once again the machine cannot now connect to the network. Following this I failed to find this post (I was very tired at the time) so raised another bug (#236287) which should get marked as a duplicate of this. As I have tremendous problems with X under Gutsy I am therefore leaving this machine in it's current knackered state until a patch becomes available (I can always boot from Knoppix when I need to use it to do some work) -- RTL8111/8168B does not work in Hardy https://bugs.launchpad.net/bugs/221499 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
