Somebody has hacked my home internet. I have their MAC Address and IP Address but I'm assuming it's a VPN because it's showing their location off the coast of Nigeria. I paused their access on my wifi thru my Xfinity app. Should u be safe now because I've changed the password a few times but somehow they keep being able to join. I'm not the most tech savvy so any help on how to resolve this matter would be greatly appreciated. Also if they were able to log into my wifi should I be worried about personal info on all my devices that are also logged into my wifi? Thanks in advance for any help you can give.
