RSN Checker Script

Looking for a script that can check for and lock in available RSNs with a set character/number variable.

For example;

The script can check for 3 character RSNs using a combination of characters or numbers.

Script can check for 4 character RSNs from a set specified list of names set by the user of script.

Keen to see if anyone has a script like this? If more information needs to be provided please let me know.

 

hm?
