Installation issues / Re: Installing LinuxMCE on server - installer issues, networking, video playback...« on: September 22, 2014, 04:44:35 am »
For me, this was the case. The NICs were recognized by the OS but weren't "up" because the LMCE install logic failed to configure them.
The reason for that: turns out my cable modem requires a power cycle when the MAC address connected to it changes, otherwise it clams up. If the LMCE install logic can't find a path to the internet on either NIC it leaves them both down I think. See if you can bring one of them up with ifconfig and run dhclient to verify DHCP is working and you can reach the internet.
