|Hi there ,|
To find your network key, you need to log in to your router.
and for logging into router you need to know the username and password for that which is normally provided by a internet service provider or it willbe written somewhere in router manual.Without knowing your exact router model this may be hit or miss...
Open up your internet explorer browser and type in 192.168.0.1 If that won't go anywhere, the number could possibly be 192.168.1.1
It will ask for a username and password.
Provide the username and password.
Once you are in, there will probably be a button up near the top that says "setup". Click on it and then click on "wireless settings"
The key you are looking for will be in there somewhere. You may have to choose "wep wireless security" or something similar to get the settings. Again, it's really tough to do without know what model of router you have.
Hope this helps you.
Best of luck
