    Good afternoon,

    Thank goodness I have Win XP running under Parallels 5. That's the only way I can get Ethernet to keep working. I don't think it's hardware; I think it's OS X as you'll see below.

    I'm a Mac newbie, but I consider myself at least reasonably computer savvy (actually got the Power User compliment from a software guy in my office) and can contribute this troubleshooting tidbit:

    I had to edit some video off my company's server 2 days ago, and the Ethernet in OS X went from dropping to not being able to connect at all when I tried to hunt for the clips and open them off the server. I wasn't going to bring it in over Airport so I used Win XP to put the clips in the Parallels Shared Folder so I could open them in iMovie. Aside: iMovie rocks! I've never edited video #1 and have now made 2 short videos with fades and some animated text with just 30 minutes in the iMovie tutorials.

    Just to make sure they weren't coming over Airport when I imported them into the Parallels Shared Folder in Windows (both Airport and Ethernet showed connected with assigned IP's, etc in Network Preferences even when Ethernet wouldn't work in OS X), I shut Airport off. Windows was solid the whole time, and I pulled the clips in over Ethernet as planned. For what it may matter, the Ethernet port is in Shared Networking mode in Parallels.

    Imagine, having to have Windows rescue OS X. Not what I expected when I went all in Apple from my Verizon Blackberry (to iPhone) and Dell laptop.

    Glad to be aboard. Hope this helps.

    Add another 13'' to the list - exactly the same symptoms. Very frustrating.

    Adding my name to the list. MBP Core i7, I did not do any automated software migration and the OS is factory clean. What brought it to my attention was the install of Hardware Growler. I am connected to only a wifi (via TimeCapsule) and have not yet plugged an ethernet cable into this laptop.

    When it occurs I see the following entry in the system.log

    May 6 13:01:46 mbp configd[14]: network configuration changed.

    There is no entry in the kernel.log when this happens.

    Hi,

    Just bought a brand new Macbook Pro 15" i7 With antiglare HiRes, 7200 RPM Drive. I can confirm that the problem exists by checking the network settings and monitoring the status. 70 seconds later it goes orange, status: "unknown" then to Red Status: "Cable Not Connected". I didnt use migration assistant and didnt install any other software yet. I don't have anything in the console logs to show the issue and it doesn't seem to be noticeable if you were not looking for it. I happened to cross this forum and just checked to see. I installed growl and I now get the "Ethernet Deactivated" message every 70 seconds.

    Oh another observation, if you use wireshark to capture packets, every time the ethernet deactivation occurs, there is a DHCP request, so it actually looks like the interface is reset every time this happens.

    No. Time Source Destination Protocol Info

    Just bought a 15" i7 and am seeing exactly the same issue; I'm very happy I'm not the only one! I get a pair of ethernet disconnect messages every 70 seconds, if I'm connected to a wireless network.

    I also noticed this due to having Hardware Growler installed, but I can also confirm that it's not a problem with that -- it's just doing the right thing and showing me that something is going on.

    I don't suspect this is a functional "problem", but it is a bit of a nuisance since it clearly shouldn't be doing this and I don't prefer to just tell HwG to ignore my ethernet port entirely (it's really useful for knowing if sketchy ethernet jacks at hotels work or not). Here's hoping that this is a quick OS X fix.

    One final note: I also discovered that removing the ethernet connection in the Network control panel (assuming you don't need ethernet) stops the problem. You can also create a new location with the ethernet connection disabled so you can quickly turn it on and off depending on what you're doing.

    Same here ! I just had My MBP 15" Core i7 delivered and I have the same issue while on wi-fi. I get disconected eth0 messages every 70 seconds. Was made aware of it after installing Growl Hardware.

    Glad I'm not the only one but really hoping for a fix or an aknowledgment by Apple

    Same exact problem. MBP core i7 2.66 15". very annoying, especially when using SSH. Apple please find out whats wrong. Even with a ifconfig en0 down the issue still happens over wireless. If you run a constant ping to a gateway address it will time out every 70 seconds..

    Console shows:
    5/11/10 11:33:20 AM kernel Auth result for: 00:24:6c:ba:72:e0 MAC AUTH succeeded
    5/11/10 11:33:20 AM kernel AirPort: RSN handshake complete on en1

    Which is interesting since I use WPA2-PSK not MAC auth.

    I have a mid 2010 i7 15" MBP. I get the same Growl notification and the same status change other see in Network Preferences, however I have no krb5kdc message in on my Console Log.
