I have 3 computers on my wireless network (PC, Dell Laptop, Sony Laptop). All of which were connected fine to my wireless network and working as expected. A few days ago, I ran the Windows update for my Dell Laptop and it installed MS Service Pack 2. Ever since this update, the wireless connection on the Dell Laptop will become disconnected every 5-10 minutes. There is NO disruption in connectivity to the other systems on the network. This is VERY frustrating, can anyone help?
