i forgot my network key and im trying to set up another wireless adapter. where can i find if possible?

Answer 1

Try logging into the router. Some brands/models will display the key in the router's setup page, others won't. Even if it doesn't display the key here, you would at least be able to reset the key to something you know.

Answer 2

Try logging in to your router using a ethernet/network cable and enter the routers IP address into your browser. (search the manual for the default IP address/username/password)

If it does not work, try changing your IP address to a manual one within the same subnet as the routers IP...i.e. routers IP = 192.168.0.1..so your IP = 192.168.0.2 (upto .99) (Subnet mask with both = 255.255.255.0)
