[SOLVED] Someone is accessing my wireless network. How do I revoke their access & prevent further interaction with my network?

Question

My upload/download speed suffers due to this inconvenience. Any advice would be appreciated.

Answer 1

I don't think you need Kali Linux.
If you connect to your Wi-Fi and enter it's IP address in the search bar, it should take you to the router management settings. There, you should be able to see who's connected to the wifi and be able to block them... at least that's how it is for my router.
You should probably contact your ISP or simply change your password as recommended by Frost. They'd probably be easier and faster than using Kali but if you're adamant on using it, you can Google videos on how to use Kali to achieve this

Answer 2

Enter your router's default gateway into your browser's url-bar. It's usually something like 192.168.***.*.

You'll likely be presented with a login screen. Google the default credentials, sign in, and navigate to your security/firewall settings. Also, assign your own credentials regarding the login, rather than leaving them as the default credentials.

Answer 3

Change the password?

Answer 4

Just like others said, login to your router management/settings page.
Check out who's using your wifi, there would be a list of Mac addresses of each device connected to your device. Lookout the mac addresses of your devices, if you find any mac address that doesn't matches with any of your device's mac address, put it into mac filter list.
And do change the password.

Answer 5

Try what CipherFox said. Your login should be "admin" and the default password is normally on the box or with the router packaging.

If the person has taken over (by logging in and changing settings via CF's method):
1. Find the factory reset on the router (usually a paper-clip-sized hole).
2. Using a paper-clip if needed, hold the reset down for 30-60 secs.
3. Connect via ethernet to router.
4. Enter default IP (on packaging).
5. Login (default details on packaging).
6. Change login details.
7. Set the AP name to hidden and make it simple, eg: MyWifi.
8. Set the AP password to WPA/WPA2-PSK and make it long without real words, eg: ZaOfftenzeFurDasMettAlFurden000 (you'll memorise it over time though it's gibberish).
9. Call your ISP if needed for any required settings. You may need a friend's help getting online here.
10. To connect over wireless, you must enter the AP name manually as it is not broadcast, followed by the password.
