Q: iMac 27" Late 2012 i7 Loosing ETHERNET connection on wake

There are a lot of threads addressing this problem for Wifi, and I understand it's a known issue. However, I am experiencing this issue with an ethernet connection.

 

When my new Late 2012 27" iMac i7 wakes up from sleep mode, the internet connection takes a minute or more to come back (I keep refreshing chrome until it works again).

 

This is not a router/ISP problem as I have had a PC connected to it for years with no issues (it is currently still connected & working fine). I am running OSX 10.8.2 and it is up to date.

 

Has anyone figured out the cause of this issue?

iMac (27-inch, Late 2012), OS X Mountain Lion (10.8.2)

    Make a New Location, Using network locations in Mac OS X ...

     

    http://support.apple.com/kb/HT2712

     

    10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    If still a problem...

     

    In the network pref pane for Ethernet>Advanced>Ethernet tab, instead of Configure Automatic, try Manually>10 BaseT Half Duplex for a start & work up after reboots if the slower works.

    Great news, thanks!

     

    Did the first suggestion fix it?

    Actually, it did at first but now the issue has returned. I'm having trouble following this part in bold:
