Sorry, it’s the MAC filter that I can’t get to work. So I just reset the router and was prompted to reset my router access password and the network password, which I did. I’d like to set things up so that I can use the MAC filtering to enable some devices but not others. When I tried this, I was able to save the changes. But I was unable to connect with a device that I had set up to have access–my new password was denied. Right now, I’m left to just disabling the wifi altogether to regulate it–but I’d like to get the full system to work again so I can regulate device by device without any difficulty. Any advice?
