oh god..
right.. find problem first. Wireless router! Can you access the router? You use a web browser and the address is something like 192.168.1.0 (for example). If no little log in box appears you will need a bit of cat5 cable to connect your computer to the router manually. If you have the drivers installed properly it will connect automatically using above address (or the correct one like it).
Once you can "talk" to the router, access the setup program in the router (login admin/admin is common) and turn off any security for the wireless. Use the connections manager to search for a wireless connection. If it works ok then you need to set up the security (follow instructions.. psk string is easiest and best). If not you need to reinstall it from scratch.
This is sometimes a tricky thing. You must get to communicate with the router though. Got any instructions with it?
