Hi can anybody help me please I live in a house share where we all pay our way for the wifi - one person in the house is refusing to pay and I've tried changing the password and it messed up the modem so I'm trying to find an alternative way to just block out this one persons device, is this possible to do if so can anyone explain as best as they can how I go about doing this. Thank you very much.
Welcome to our forum, shame that somebody is unable to pay, it is possible in theory to block devices from their MAC address, we have an article here that explains more Setting up MAC filtering on my router
If you log in to the router via 192.168.0.1 then click on the tab that says 'device connection status' you get a list of all the devices that have connected. Perhaps you could use this to show the person that since they are using the WiFi they should pay? Just a thought, but I realise they might be not very easy to reason with.
