I would look at this as two seperate issues, and focus on the wired connection first. Once that is confirmed working, move on to the often more complex wireless connection. For now, to prevent possible issues, disable the wireless connection, and connect wired to your LAN.
What are you connecting to? Is it a router, or directly into a modem, or a hub?
From the start menu, enter cmd in the search box and hit enter, then type "ipconfig" without the quotes. What is the IPv4 address, and the default gateway listed for the Ethernet connection?
With this information, we should be able to troubleshoot further.
The only way to learn anything is to question everything.
