My Acer laptop won't connect to the wireless network?

I have an Acer Aspire 5733Z-4851 laptop and a netgear router. Usually I can connect it to the router with an ethernet cable, but it has never connected wirelessly, although it has a wireless card built in. For some reason, now when I connect it (wired) it won't connect to the Internet. I keep getting a notification from Windows saying that it can't connect to the internet (it'll say this when I attempt wired and wireless connections, I simply don't know what to do at this point). Please help!
