First time ever I got my wireless networked hacked into. The ip of the router was changed, wireless disabled, and web based configuration was off. Tried the old and new adress. I did not have any wireless encryption but I did have the MAC filter enabled. There was also a password to get into the router. After a hard reset I set up the mac filter and WPA-TKIP security. Am I still voulnarable? What can I do to prevent this from happening again? How did the hacker get in through the mac filter?
