This seems to be another case of the r8168 driver not properly negociating speed and duplex. Reassigning to 'linux'.
As a workaround, you may wish to try installing ethtool and using the following command: 'ethtool -s eth0 autoneg off' ** Package changed: network-manager-applet (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/969793 Title: RTL8111/8168B wont come up and causes Kernel Panic Status in “linux” package in Ubuntu: New Bug description: Problem NIC is an LogiLink® PC0029 lspci says: RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) ubuntu wont detect the plugged in network cable after a fresh install and after installing all aviable "normal release" updates. NIC is working perfectly under other OS, so a Hardware issue can be ruled out. I tried fixing it by installing http://r8168.googlecode.com/files/r8168-8.028.00.tar.bz2 by running the included "autorun.sh" now the NIC gets up, but im still not able to get an IP from local dhcp. Sniffing directly on this NIC ( connected via crossover to another PC) in Promiscuous mode shows there was a DHCP Discovery sent out (recorded on second PC). After setting IP Manually on the Problem NIC and on the other PC I have tried to ping each other. Sniffing on the problem nic (recorded on "Problem PC/NIC") schowed, that the Problem NIC is not recieveing any packages. While Testing this interface with "ping -I eth0 -b -f 255.255.255.255", NUM Lock and CapsLock LED on Keyboard began to blink and system freezed. After this i have booted Knoppix from a live CD without touching any network Hardware.And There Problem NIC worked perfectly without manual configuration.
