[ubuntu] Problem with Network Computer and Sleeping Laptop

view full story

http://ubuntuforums.org – I am new to Ubuntu and am having some problems. I closed the laptop lid to sleep the computer. When I opened the lid to open it, it did not wake up so I turned the computer off. When I turned the computer back on, it said that networking was disabled and it showed the wrong time. Now I am getting a Window asking me to enter a password to unlock a keyring. It does not accept my password and says that the password I entered is wrong. I tried both my login password and the password I created for the keyring. How do I unlock the keyring and re-connect to my wireless network? How do I fix the time? (HowTos)
