I have 2 laptops and a PC connected to my router to access the internet. The laptops are wireless and PC cable. All three connected without trouble to the internet.
I have upgraded one Laptop from XP SP2 to XP3. Since then I cannot access the internet. I do connect to the router. If I look at the wireless network properties it shows as connected, good signal strength but there is now a picture of a lock. How do I unlock this so I can connect to the internet again.
