Hello,
I have a fresh installed F12 on my machine. For some reason, the NetworkManager always prefer to connect to Wireless network rather than to using the ethernet connected cable (System Eth0). Even when before turning on the machine, I already plug in the ethernet cable, after logging in to KDE the NetworkManager still picks the wireless connection. I have to manually disconnect from wireless, and choose System Eth0 everytime to use the ethernet.
This happens both on my work campus, which has open wifi network for visitor, and at my home network with WEP. On the workplace it would connect to the open wifi, at home, it would prompt me the Keyring manager and then connect to the wifi, both time with cable plugged in to it.
I tried to search on Google, and look at /etc to find out where I can change this behavior, but haven't had any luck.
Several other laptops I set up with F12 for friends do not have this problem.
Thanks for any help. AC
