Mac Address Filtering - Where?

[#1]

Hi
I've just received my new Plusnet Hub One (Sagecom router) but there doesn't seem to be a section in the settings for mac address filtering. I like to make sure that only devices with mac addresses specified can connect to my router.
Have they forgotten to add what to me is a basic security feature or am I just not looking properly?
Thanks in advance for any help.

I think MAC address based access control doesn't really add much security anyway.

I dont think its possible with the hub1, anyway it adds very little in the way of security and is easily breached,  far better to use a strong password
