It depends on what you define as "Wi-Fi code" as there are about 3 things this could be. I will go through each of them and show you how to resolve connecting your computer (both in Mac OS x and Windows 7). I will explain how to find them if you have not changed any of the passwords or names:
Firstly it could be your actual Wi-Fi broadcasting SSID. This should be down to you to remember. However, on most routers it is posted on a sticky label someone on the exterior. Once you have found this it is a case of selecting it on your computer. (See my last paragraph).
Secondly, it could be your router password (WEP, WPA, etc...) this could also be found on a sticky label on the side of your router. Once you have found this it is a case of selecting it on your computer. (See my last paragraph).
Lastly, it could be the router password. This is essential to remember to change individual settings on the router (for example: Ip addresses, access control and port forwarding). This is normally on the side of the box for the router. Or on the instruction manual or documentation. After this it will be a case of logging in to the ip address remotely to change settings.
Sometimes, if you have been sent the router from a service provider, there will be a card sent with the router which will contain everything i mentioned could be wrong. If this is the case it should be someone inside the packaging / documentation that arrived with the router.
In OS x go to the menu bar and click the wireless signal icon. A drop down list will appear with all the networks in range of you, select your one. In Windows 7 there is a icon in the bottom right corner of the screen (in the case of this being hidden, show the hidden icons). Click it and select the network. This will display a button stating "connect", click this and your computer should connect to your router.
If all else fails manually reset your router, there should be a small button on the side of your router. Once this is pressed you should be able to connect to your router using it's default settings. Your internet service provider, isp, will have details for this normally.
