So I'm using a H368N ZTEEG04E6R01093 and im trying to block a person in my house on my wifi, because the person is taking up waaay too much bandwith. (and yes i have a password on my wifi, also not a factory one) In the system settings for this router when you type in 192.168.1.1 and log in, you can simply block someone from your net like with other wifis. (This is because my ISP apparently choosed to remove certain features from this router for some reason) I know the method of blocking a network in the basic way, but it seems like when I try to use the "MAC Filtering" it wont work. (My guess for this is that i lack the knowledge of it, however I do understand it, the Filtering proccess for MAC, need a Source mac addres and a Destination address(http://imgur.com/a/7RlaV) and i don't know how to get hand of a Source and Destination address) Then there's IP Filtering. Okay this is something I quite not dosn't understand. (http://imgur.com/a/1S2yZ) I have all kind of ways of obtaining the IPs MACs and so on. This problem isn't like any other problem ive faced before so I need some help with configuring the Blocking proccess. Mainly becuase I don't want to be unable to use my WiFi at all only because one person is taking up all the brandwith. (No it is not possible to get more brandwith and also not faster network since it isn't available where i live)
