I believe that to be a straight dictionary hack, performed in low case only, and not caps/lows/nums/chars... I believe it also requires knowing where the internal gateway is, which may not be standard (mine certainly isn't).
And even if so, who has it out for you so bad that they are willing to spend 8 hrs hacking your wifi? Only for you to discover the wayward name in your dhcp table and reset your passwords again?
meh. Routers are pretty bulletproof. Change the access password, change the IP range, change the password to something relatively safe, and you're golden... Unless you are wanted by the FBI or you pissed off your hacker ex.
Sorry that is incorrect. It is a full alphanumeric 95 character set.
8 hours is done by a machine and can be done overnight
So set up a laptop, start recording the wifi traffic, force a station or two to reconnect, and in 4 hours you will have the wifi hash recorded. Go back to the laptop, extract the wifi hash, pass to a cracker box (some are dedicated hardware, some can be ordered from the cloud). Crack the password over night and come back the next morning with the password and you are on the wifi network.
Trust me, that is a standard penetration testing practice. That is one of the tests that my team performs for banks and S&Ls
