[SOLVED] Wired network keeps diying

Hello everyone, this is my first post.
I've been running linux -as user and home-admin- for almost 10years now, and Arch linux for the last 1 and a half.
Never had any serius problems, but right now I'm stucked with a network problem.

My computer runs arch&win7, win7's network is working perfectly, and arch's network was working until yesterday, so the problem is not the router, wire, or network port, since win7 works.

My issue is that the network -wired- keeps diying every ~40seconds, and I have manually to reset the network in order to get it back for another ~40seconds (sudo /etc/rc.d/network restart)

Last thing I did before my problems started, was just reboot, boot windows, played duke nukem for a while , and when I came back to arch, problems started.

I would aprreciate help sooo much, since i ussually need to connect from work to home (dev branch server (apache+mysql+php) is running on my computer, don't ask why).

ifconfig output:

Re: [SOLVED] Wired network keeps diying

Ok, solved
This was really stupid but was driving me crazy.

On windows I use dhcp, on linux, static ip.

While I was on windows, my phone connected my wifi ussing dhcp, and got my linux's ip.

So, when I came back to linux, I had an IP conflict, and my conection died evertyme.

Turned off my phone's wifi, and everything is ok.
