Description of problem: This machine has 2 network cards. pcie card: D-Link System Inc DGE-560T PCI Express Gigabit Ethernet Adapter (rev 13) [works fine] and on the MB Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 03) [it may have stopped working with the 3.10.* kernels] Immediately after the install, both worked fine. After the first kernel update, the realtek card stopped working altogether. I have tried allowing NetworkManager to control the card and not doing so (both ways work under fc 17). To check that the card is working, I put the old root (drive) file system from fedora 17 back in place, and when I booted, both cards came up and worked as expected - and did so for about 6 hours before I swapped the drives back and went back to fedora 19. I'm not sure whether this is a NetworkManager problem, a kernel problem, a library problem or some other network-specific problem. So the NetworkManager "component selection" above is a best-guess approximation. manually setting the routing for the card does not help at all (or appear to work). The D-link card controls the external interfaces (ISP, other non-local systems) and the Realtek card is on the local (192.168.1.0) network. Version-Release number of selected component (if applicable): Not sure it's relevent but: NetworkManager-0.9.8.2-8.git20130709.fc19.x86_64 kernel-3.10.7-200.fc19.x86_64 (same as with all other 3.10.* x86_64 kernels) How reproducible: Happens every time Steps to Reproduce: 1.Reboot the machine (or restart network and NetworkManager) 2. 3. Actual results: D-Link (sky) card works as expected Realtek card cannot contact anything on its network. Expected results: Both cards should work as expected Additional info:\ Immediately after the initial install, both cards worked perfectly. But after running yum update, the problem appeared. Since there were > 400 updates in that first batch I don't have a clue which of them triggered the problem.
