First thing to try would be to reset the router. Next, PRAM/SMC reset.

If there's still an issue, try open Device Manager on Windows and check the Wi-Fi card, right-click and select Properties. Is it coming up with a Code 43 error or anything like that? Does it show any visible networks?

In OS X, when you click the Wi-Fi icon, does it show visible networks or display nothing? If it shows no visible networks, please can you access it through the Network Preferences pane and see if clicking the drop-down list for Network Name displays anything?
