My motherboard is an Asus A8N-VM CSM, NVIDIA nForce 430 chipset. Symptoms are very similar but show randomly. First live CD boot went well. Once installed, I get random behaviour (sometimes works, sometimes doesn't). My network fails both at startup and after some time of using Firefox to surf the net.
Deactivating and activating back eth0 via the Network Settings panel makes it work. Sometimes, after a while it'll fail again, though. Then I do the deact/act thing and it's back. /etc/init.d/networking restart doesn't make it work. Setting my IP manually doesn't help. Once I get the connection to work, I experience the following: Setting the router (192.168.1.1) as the DNS server makes surfing slow, but won't fail so often. Setting my ISPs DNS servers makes it still slow, but again makes it work more often than not. Setting no DNS servers (letting DHCP solve it) makes it work faster but fails more often. I'm not Linux expert and don't know how to install official NVIDIA drivers yet. Once I learn how to do it, I'll report back. -- Ethernet interface not working after reboot https://launchpad.net/bugs/42608 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
