I installed Centos 6.4 on my laptop and neither of the network interfaces will work. When I boot up to windows both the wired and the wireless network interfaces work. I have attached dmesg output for the wireless card. Reading through the messages it appears that OS cannot talk to the NIC. -- Selwyn Schultz selwynsr@xxxxxxxxx c. 616-836-8896
