Keyspace List for WPA on Default Routers

[duhblow7]

ssid = DG1670AXX
preshared key = DG1670A+[0-9A-F][len6]

Example:
SSID = DG1670AB2
PSK = DG1670A919DB2

keyspace = 16^6 = 16,777,216

edit- I cracked a few more of these and I noticed that the last two characters of the PSK are the same as the last two characters of the SSID.

This takes the keyspace down to 16^4 = 65536
