Then go down to privacy settings, pick which encryption type to use ( I recommend WPA-PSK or TKIP) if that doesn't fly with your laptop (or other wifi stuff) then pick the highest encryption method that all of your wireless devices are capable of (like WEP) 64-bit, 128-bit or 256-bit. 

 

Most devices use 64 and 128 bit, but if all of your devices use 256, then use it. Then create a wireless key to use, If the key is selected, the WPA key can be any random string of up to 63 characters (with the possible exception of blank spaces), the WEP Key is treated as a string of text characters, and the number of characters must be either 5 (for 64-bit encryption) or 13 (for 128-bit encryption) or 29 (for 256-bit encryption). 

If not selected the WEP key is treated as a string of hexadecimal characters and the number of characters must be either 10 (for 64-bit encryption), 26 (for 128-bit encryption) or 58 (for 256-bit encryption). The only allowable hexadecimal characters for WEP (hex) are 0-9 and A-F. 

 

My hint is to use hexadecimal, it is easier If you want a truly random password go to this site (passwords) and select which one you want to use, then copy and paste it into the correct key box, save the settings and type the same key into the NETWORK KEY boxes that windows should present you with. 

 

If you have trouble connecting after all this you may need to go to the properties of your wireless connection and delete your preferred networks list, then try again.
