Need help with linksys router!

[Pumbas]

My router is configured to cut the internet on a determined time I need to find another way to conect to the internet, I can not acess the router page because I do not have the password.My dad did this because he thinks that I am not going to sleep but he does not realise that I can bot all night long while sleeping, my brother he had some kind of pen drive that would get the signal of the router and create another signal, because only a few machines are blocked, my ipod touch is not blocked, my xbox also, and the host of the internet ( my dad`s pc ), the password is not admin, he totally change and he put to save the password and login on ROBFORM, something like that I tried to press to enter the password and login but ROBFORM asks for a master key password, any tips?I also tried to make my ipod itouch as an hotspot but it needs 3G, It can not do with my linksys signal.
