Assuming it's a managed router, which most are, you'd probably want to refer to the documentation to navigate to the configuration page and be able to enter the administrative credentials to access it.
Typically, router configuration pages can be accessed by typing in 192.168.1.1 in your browser's URL bar, but some have different gateway addresses, which will be noted in your documentation.
Also, usually the username will be "admin", and either have a blank password or a default password in the documentation or on a sticker physically located on the router.
Once you're in the config page, you should see something to the effect of access control or security, etc. Basically, you're looking for anywhere it allows you to put a MAC address in. Usually the default is to have MAC filtering disabled, so in order to enable it, you'll have to set it that way in the pertinent section. After enabling it, you will be required to enter the MAC addresses you wish to gain connectivity through the router. You will have to add the MAC address of every device that connects to it. PS3/Xbox, Laptops, phones, PCs, etc.
This is good if you want to make sure you control who uses your internet, assuming they can get through your passcode, assuming you have one implemented.
If you just want to make sure you're NOT filtering MAC addresses, you would just log in and ensure no MAC filtering is enabled, in the configuration as described above.
Pretty much any modern router will have MAC filtering, but I have never seen one with it enabled by default, since you would not be able to connect to it out of the box, which would make configuring it a bit hard...
But you would definitely want to check that someone has not gone in and enabled it after the fact.
