Okay, when ever i leave my computer desk and let my pc sit in idle, the internet shuts off after an 1hr to 2 and goes into "Unidentified Network." the only way im able to get my internet back is if i go to mange network and disable and re-enable the network, works fine until i leave my pc again. This problem has started ever since i got my new PC Im running Vista Ultimate x64 on the machine atm. Every other computer in this house is not having a problem but they are running on XP. My last pc was running on Vista Home Pre x64 and it never had this problem iv been googling and trying to find out the problem but i give up i was hoping if there was anyone out there that could help me out plz!!!!
