Hello All, I am a recent Mac convert - I just purchased the stock 15" MBP last week. I have run into a strange issue recently (it started today actually). Each time my MBP goes into sleep mode, I lose the connection to my wireless network. As I mentioned, it worked fine for about a week and now today this issue started. When I try to access the Internet via Safari I get this message: "You are not connected to the Internet". I then click on the "Network Diagnostics" button and under "Network Status" I see the following: AirPort - Green Light Airport Settings - Green Light Network Settings - Yellow / Amber Light ISP (Failed) - Red Light Internet (Failed) - Red Light Server (Failed) - Red Light While I am getting the above, I still have full, uninterrupted access to the network on my PC. I then continue on within the Network Diagnostics window and reselct my network, enter in my network password, and then all of a sudden all is good again and I have access to the Internet and it says "Your Internet connection appears to be working correctly." The strange thing is that this happens everytime I wake my Mac up from sleep mode. I am sorry for the long post, but can anyone help me out? Much appreciated!
