Unable to connect to my home wireless network

[Malydia]

I am unable to connect to my wireless network. The networks are being found but when I try connecting to it, I am not getting through. This is happening even at home using my home network.

Which operating system have you installed in your pc? Is it a laptop or a computer? What is the make or model of the laptop or what is the computer specifications? Which router are you using? It could be that it might need a new IP address. So, simple rebooting of the computer and resetting the IP Address of the computer can take care of the issue.

Thank you for your reply. I have a dell studio 1535 series laptop and the operating system is Vista. I have tried setting the sytem to its factory settings and it still didnt work.

When I connect the modem directly to the laptop, I am getting connected to the internet, but when I use wlan, I am unable to connect even though I am finding the connections. I thought the problem was the Wlan card, so I bought one and changed it, and it still didn't work.

Do you have any antivirus or any firewall installed? If yes then try to turn it off and then try to connect to the network. If that doesnt work then restart your laptop and press F8 at boot and run safe mode with network support. See if you can connect. If you can then you have something running in the background that is preventing your connection.
