Network Dies every 5 - 10 minutes, Start/Stop Fixes

I am on a HP laptop at work. Every 5 - 10 minutes my network connection stops working and if I do deactivate/reactivate it will start working again.

Here is what is in the log file, during that time period.

What could be the issue? I asked some of our sysadmin's if I needed to do anything to get fedora working in our domain. They use unubuntu with no problems.

Disable IPV6 on your box* and add valid DNS entries from your ISP to your /etc/resolv.conf file.

*= add the following lines to /etc/modprobe.conf:
alias net-pf-10 off
alias ipv6 off

Ok, I made the changes to modprobe.conf.
My resolv.conf had the correct DNS entries, already.
Then I rebooted. Seemed to boot faster, too.
I will surf around a little and see if the connection is stable.

Thanks for the reply.

Do the network link LEDs blink off when you lose the connection ? I suspect so. Normally loss/restore of connectivity (link) causes these messages and similar.
Nov 15 09:47:01 LLX1002481 kernel: ADDRCONF(NETDEV_UP): eth0: link is not ready
Nov 15 09:47:01 LLX1002481 kernel: e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex
Nov 15 09:47:01 LLX1002481 kernel: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
This could mean a bad cable or a bad slot i nthe corporate switch.


It is EXTREMELY unlikely that /etc/resolv.conf is related to the problem as it is an upper protocol and you are losing connectivity. Find an absolute IP you can always ping (like ping 4.2.2.2) and *if* you can still ping it when you are having problems then *maybe resolv.conf is the problem. Most likely not.

Here is the requested output. One thing is, when my network is down, I can't ping via ip addy. I don't think it is a resolution issue.
Also, I have been using this laptop, cable, port for a while and had no problems. The issue happened as soon as I switched from XP to FC6.

==SOLVED==
Stevea was the closest to the right answer. I just found out that somehow my laptop and a video conference device were using the same IP addy.
Every five minutes the device would knock me off, and then when I would disable/enable the port it would kill the video conference.
They are researching how I got that IP in the first place, since my client is set to DHCP.
Thanks for the help!
