I've been having conflicting issues with my on board NIC and my Linksys Ethernet Card. The card will work every other boot up (50% of the time). I can just download the chipset driver for my board, but I have the Linksys in there. I have the on board turned off in my bios. Any ideas why the two are conflicting?
Computer specs are:
Phenom II 940 BE
4GB Corsair 1066
Have you also disabled the onboard nic in windows device manager? Disable it. Do not uninstall it as windows will find it again and allocate resources for it and your problem will come back. Good Luck!
