I purchased my HP Pavilion DV4 yesterday. I have an issue with my wireless connection. When opening the lid and unlocking the computer after a period of inactivity, it says that I am connected to my Netgear wireless network but I am unable to access any web pages unless I restart the computer. Can you please advise as to why this would be happening? I am running Vista Home Premium 64 bit. It is getting quite annoying. I don't have any problems with my Macbook or my Dell Mini Netbook.
