I can't connect to the internet on my family's routers. My brother has blocked my Xbox's access to the internet for his IP phone network. He uses Tomato( I think it's one or two or three years old, not sure) and I'm not sure how to get past the firmware because I don't know the password. He uses a WRT54GL Linksky's model and when I switch the router with a different Linksky's router(WRT54GS) it still doesn't work. If there are any ways to get past this it'd be greatly appreciated.
