The time for my WPA2 Password cracking increased a lot after secifying chrset

[Super_X]

for this kind of attack you have to put a little afford beforehand, there is no builtin or easy way to achieve this

first prepare a wordlist with the words you remember
second generate a second wordlist from that with 1-x Chars (with suitable charset) PREPENDED to that words third generate a third wordlist (with the first one) witt 1-x Chars APPENDED to thats words
merge list 2 and 3 feed this list and some rules to hascat,

you can use hahscat utils for the steps obove

Uhm. Can you please describe this process better? And what hashcat util tool should I use?
