I have another account on here, but for some reason I'm not receiving a VM email link to reset my login info after submitting the request, so I made this one. Anyway, here's the problem:
I checked my hub page today because I noticed something weird was going on. On my phone, under my WiFi symbol, it said that there's "limited connectivity", and asked me to tap if I wanted to connect anyway. I connect anyway, and I can use the internet just fine, but it still says "limited connectivity".
So, I went to the hub page to see what's going on, and I noticed that there are too many devices connected via WiFi. My partner and I turned off all our wireless devices, and it still says there's an 'unknown' wireless device connected. A MAC address manufacturer lookup returns nothing.
So, I looked into how I could block this device. I tried MAC address filtering but it doesn't make it easy to know whether I'm blocking the address or doing something else. I also changed my WiFi password
I've attached two pictures to this post, which show my MAC filtering settings. The ethernet is my PC that's connected via eithernet, the 2.4G one is the unknown device. On the filter list with two MAC addresses listed, that's the MAC address for the unknown device on both listings, one for 2.4G and one for 5G.
I have two questions:
1) Have I filtered/blocked this device correctly?
2) If so, why is it still showing as a connected device? Even after I've filtered its MAC address and after I've changed the WiFi password?
