So I was tinkering in my router's settings and i found QoS, where I could give myself priority with Internet bandwidth. Anyway, I saved my MAC address but everytime I clicked on save settings I didn't show up in the array of saved MAC addresses (it was empty). So I took a look around and I saw a setting which was disabled. I don't know its description, but it had three words and one of them was WiFi. So I clicked it, hoping it would help me with saving my MAC adress, but when I clicked save settings, the WiFi stopped working on all devices. I couldn't access router's default gateway wirelessly anymore, so I plugged in the Ethernet cable. Internet worked now, but I couldn't access the default gateway to fix WiFi.
Is there a way we could fix that without resettting the router?
Thank you for your time
