How do i find my wireless network security key

The security key is maintained by whomever owns the router or access point you want to use to get online. If you did not set it up, you will need to ask the people who did for permission to use their connection. If granted, they will give you the security key.

I have located the Security Key. Thank you for the info.

where is the security key located

It is located at the back of the router. It will be indicated with the prefix PSK: the numbers and the letters must be entered exactly as they appears. Good luck.
