3 Ways to Block Unknown WiFi Users (Very Easy)

There are tons of possible reasons why your Wi-Fi connection is slower than usual. One of the possibilities is someone using it without your permission. If you want to find out who is stealing your Wi-Fi network and how to kick them out of your Wi-Fi, here are 3 ways to do so.

Method 1: Using the page of the router

  • Disconnect all the things except your computer. This way is the easiest to check whether or not you have intruders on the network, as the remaining addresses that you find are owned by your computer or to an intruder. For those who have any Internet that are wired directly to the router through Ethernet cables such as consoles, please disconnect the Ethernet cables.

  • Determine the IP address of the router. If you want to kick someone out of the network from the router page, you will need to find out the address of the router. To do so on Windows, open Start, click Settings, click Network & Internet, click Status, scroll down and click View your network properties, scroll down to the Default gateway heading, and review the numbered address to the right of the heading. If you are on Mac, open the Apple menu, click System Preferences, click Network, choose the Wi-Fi network, click Advanced, click the TCP/IP tab, and review the numbered address to the right of the Router heading.
  • Head over the page of the router. Firstly, open the browser, enter the numbered address of the router into the address bar located at the top of the browser window, and hit Enter.

  • Sign in if needed. When you are asked, enter the login username and password. In case you did not set these credentials by yourself, they will probably be found on the back of the router, in the manual of the router, or in the online documentation of the router. You may also have to log in later when you try to change the settings of the router.

If you find those three ways are too hard for you, you may want to call your ISP. First of all, you will need to gather all the information to verify your identity.

For your own safety, please ask the support agent to recommend the right security settings for you.
