How do I unlock locked network

[Tim the Techxpert]

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.

Please help

Looking at your post and the replies it reminds me of something that happened to me some time back. To get round the problem I had to put the wifi Mac address into the router to allow it to connect to the Internet. Try it it would be quicker than dial up regards Tim the Techxpert

basicly run cmd and type in ipconfig and check if everything looks fine. then try and ping all of the computers ip numbers. you also need to check firewall settings in windows 7. go to control panel / windows firewall / advanced settings / windows firewall settings / protected networks. then untick you lan / wireless networks - otherwise it will bock everthing, and it will give alot of problems. also make sure of internet sharing setting. ip normally is 192.168.0.1 / 255.255.255.0 on the host computers. so make sure all the other computers are running on the same subnet mask. if you need additional support , contact me . regards, metrohub.
