I think someone's hacked my optus internet account because lately my internet has been running slow and i think ive been using up more downloads then i should. I've also tried powering off my modem for a long time (1 hour) to see if my ip will change but it stays the same, i think this is because someone is using my account and keeping the connection alive.
So I want to change my internet password. I've tried changing my password on the optus site but i think that only changes my email login password because shouldn't my internet stop working, and my modem ask me for a new password, because how does my modem know what the new password is? I've rang optus and i think the guy was trying to say if I change it on the site it changes everything so i don't know.
Any advise would really be appricated.
