While surfing to the internet it sometimes become too slow and I am realizing that someone has came into the network and acting like an intruder. I am right now getting a lot of lag with live feeds this has not been a problem before. I get the Mac address of the other computer. How can I find it who it is? Please help me to detect this intruder
