I take no credit for this script, I just found it and thought, after testing it, that I would share it here to help others. I guess they have a huge security flaw and these guys figured out how to generate the default keys for them. This is the script: https://bitbucket.org/dudux/belkin4xx/src I got a few min and tried this belkin scrpit on 4 routers I found on Ebay that were all diff model numbers, and this script does work every time. If you download the script ( it doesn't matter where you put it) then open terminal in that directory, type: "python belkin4xx.py -b bssid(the mac address) -e ESSID (like belkin.c4a) -a" This will give you a list of all possible keys, on each they were diffrent and from 4 to 15 keys, but the correct one was always there. Just 2 seconds to run through thoes keys.
