Networking problem windows vista

If you repair the connection, does this solve the problem? (Right click wireless connection in taskbar > repair)

If not, what error message do you get after repairing?

Do you use encryption for the home wireless network? If so, are you sure that the password/encryption key has been entered correctly?

Welcome to TSF,

Pls remove your current wireless profiles then re-add it again. Make sure that you type in the correct network encryption.
Removing an existing wireless "profile"

If above suggestion didn't work, remove the network security from your router then test your connection.

Pls let us know.
