Everything works fine, with the exception of the onboard ethernet, which is a Realtek RTL8105E chip. The stock CentOS installation attempts to use the r8169 driver, which does not work. I've been around the block a few times dealing with Realtek interfaces and their driver hell, but this one is stumping me. >> >> Things tried so far: >> >> -Adding pci=assign-busses to the kernel parameters >> -Installing kmod-r8101 from elrepo, old and new versions >> -Compiling driver from scratch direct from Realtek >> >> In every test, I end up with what *appears* to be a functioning ethernet interface (r8101 driver detects chip as RTL8105E correctly), or as reported by the software (ifconfig, ethtool, etc). But, I just cannot get any traffic to pass. There is a link light for the ethernet interface, but no actual activity when testing. >> >> Any thoughts? > > Hi Tim. > > If this NIC is built onto the motherboard, would it not be > easier just to find an (PCI?) expansion slot NIC that is > known to work out of the box on Centos 5.5 and use that > instead? Or the other option could be to use a USB to RJ45 adaptor instead of the onboard NIC? http://www.amazon.co.uk/USB-LAN01-Usb-lan-RJ45/dp/B000CCZP88/ref=sr_1_3?ie=UTF8&qid=1345222425&sr=8-3 Keith ----------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------
