I get disconnected from the network (i.e., the internet) when my machine has been idles for a couple of hours. I need to restart to get re-connected. After three calls into my software consulation company, they were not able to fix it. I am connected with an ethernet cable and there is no problem with the internet service (my other computer works fine). The power management options include 1) allow the computer to turn off this device to save power, 2) allow this device to wake the computer, and 3) only allow managment stations to wake the computer. I unchecked the first one, but it did not fix the problem. If #2 is checked, then #3 is automatically checked (that is, I cannot have #2 as the only option that is checked). Please help! This is a real pain and I have already spent countless hours trying to fix it.
