I just installed Linux MCE 0704. As I started installing I noticed repeated disconnectes of my adsl connection. When the system was fully installed and booted, my Linksys Router was unable to establish an adsl connection. As soon as I plugged the network cable out of the Linux MCE machine, the problems were all gone.
The Linux MCE System is in the same ethernet segment as the dsl modem and the wan port of the Linksys router. Does Linux MCE somehow try to talk to the dsl modem?
