There are many innocent Wi-Fi users who pay their bills but they don’t know why their internet speed is slow even with high speed connection. There is no reason of slow speed until you have slow speed plan or any downloading running in background. You can see running internet applications on task manger. So the thing is If you pay for 4mbps or any speed plan then you should get the exact speed you have subscribed with. So why slow speed only because of some malicious people who are accessing your Wi-Fi connection without informing you or without your permission. If you gave them permission then it’s ok but if not then it’s stealing of your internet.
