Yes its my old linksys router, and just trying to learn some new things, and sorry if I don't know that much about it, again I'm new. Also sorry for delay, my posts do not show up right away. I did not put any encryption on it to try and keep it simple, also said it was a WRT54G. Not really focused on just a linksys router exploit though, more of a general way for hacking any router. Would be cool to try any thing like that though. Kinda funny though that with just a filter makes the network uncrackable. I have not had any luck with cracking wpa yet so if it would help crack it would putting a wep key with mac filter make it easier? I know how to crack wep just not sure how to crack a filter without a client on. And current don't want to try wpa with a filter yet seems to be very complex.
