Assuming you don't need particularly high security for any reason, you can use 64-bit WEP and put the key in where it says %26quot;Key 1%26quot;. If you're using 64-bit WEP, the key should consist of 16 characters, each 0, 1, 2, 3, 4, 5,6, 7, 8, 9, A, B, C, D, E, or F. You'll know you have it right if you cannot connect to the wireless network without entering the key.Wireless Router passcode? How do I add one?
Pick WPA/WPA2 it is the better encryption type and then the code you put in can be meaningful, such as a name or word, but use mixed alphanumeric characters.  Myh0u5e123
Ignore all other options
Then save and apply.
