LinuxQuestions.org - [SOLVED] Fedora 16 Wired connection problem

Helo LQ,

I have strange problem with my Fedora. The setup is Fedora 16 x64, KDE 4.7.4. My Network Manager displays the wired interface (p1p1) as 'cable unplugged'.

Sometimes I manage to connect by physically unplugging/plugging back on the lottery principle. I tried rebooting into Windows 7 - there is no problem with the connection. If I connect to different internal network - I have no problem, just the particular network, which has more complex routes embedded into it.

Code:

ip a l |grep -A1 p1p1

2: p1p1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000

    link/ether f0:de:f1:a2:30:c3 brd ff:ff:ff:ff:ff:ff



ifup p1p1

Error: Connection activation failed: Device not managed by NetworkManager or unavailable

Here's some log outputs:

Code:

I suspect that there could be a conflict between the KDE network manager, and the linux's. The WiFi is working fine. But the wired network interface is displayed incorrectly "unplugged".

I would be grateful if you can point me at things I need to investigate or any help provided. Tell me if I need to post other log/configuration outputs.

Thank you in advance!
