You need to keep your router secure by buying a router with good encryption. I would say 128 encryption or higher. You will need to set MAC addresses, a password, just about everything it tells you really. Especially in an apartment, where you have neighbors all around you, so if you're not secure, you could have numerous amounts of people tapping in. You don't want that. it's more than hijacking an internet connection. It could mean files, etc.
