If the wireless network is not your own, then you need to ask the network administrator for the network key. If the network is yours, then you can follow the steps below to attempt to find your network key.
NOTE Not all routers are the same. some of the below options may not apply to you.
Some wireless routers come preconfigured for wireless security. Most preconfigured routers will have a WEP, or WPA key written on it somewhere. If you see this written on your router somewhere, then use that as your key. If not, keep reading.
If the wireless network router was provided by your ISP, then you may need to contact them to find out what the configured network key is.
1 Connect to your router using a standard network (ethernet) cable, then use your web browser to access the router's setup page. This is typically http://192.168.1.1
2 If your router asks you for a password, please enter your password. If your router was never configured with a password, then usually it will have something generic. You can try some of the below credentials to login, or read your router's manual or get help from their website to learn the default login.
Username: admin
Password:
Username: admin
Password: password
Username:
Password: administator
3. Once you've managed to access your router, look for a link to wireless settings, or wireless security.
4 Once you find the correct page, you will see some fields located on the page marked Key 1, Key 2, Key 3 etc. The key with the check box, or radio button (or whichever key the drop down menu specifies) is the key you need to access your wireless network.
5. Once you locate your correct key, I suggest writing it down.
Hope this helps.
