Hi Mike, I have a similar problem with my 27" iMac i7 - except that my connection to the net is wireless.
I hadn't picked up on a pattern, so I can't confirm that it is limited to overnight sleep (though, if so, I don't think it occurs every time the machine sleeeps overnight). When I wake the machine, the wireless network is showing as connected and working - but it says there is no internet connection. In my case, I find that just going to the airport icon in the menu bar and turning airport off and then turning airport back on fixes the problem - ie when the iMac re-connects to the airport network it again "sees" the internet connection. In my case, this is just a minor niggle - so I haven't looked much harder. I had hoped that the upgrade to 10.6.3 might fix it but I haven't had time to do the upgrade yet (got some other work I want to get out of the way first) - however, since you are experiencing what sounds like a very similar fault under 10.6.3, I may be disappointed :( In your case, you are getting your internet via a hard-wired ethernet connection, so my solution won't directly work for you - however it might point to a couple of things you could try: First off - have you tried just unplugging and re-plugging the ethernet cable - I'm not suggesting regular unplugging/re-plugging as a solution - just to see if it works. Secondly, to try to make the iMac "look-for" the internet connection again, you could try opening system preferences, going to the network preferences and selecting the Ethernet connection from the left-hand pane - I'm assuming you will have the default setting for "Configure Ipv4" of "Using DHCP" - if so, here are a couple of thing you could try: - Click on the "Advanced" button and in the Window that opens select the TCP/IP tab, then click the button which says "Renew DHCP Lease" - If that doesn't work you could try, under the "Configure Ipv4" drop-down list selecting "Off" and hitting the "Apply" then selecting "Using DHCP" again and again hitting "Apply" - this is the closest thing I can think of to my "solution" of basically switching the connection off and then on again. I have only just thought about these options when considering your problem, but I could also try the same thing (but on the Airport pane of the network preferences) the next time I see my problem. Let us know how you go. Cheers Neil -- Neil R.
