Hello,  i'm new here. I'm suspecting someone hacked the modem/router,  because i saw  5 connected devices in my router,  but there are only 4 devices in my house,  at first i thought it could be just a glitch,  maybe one is duplicated, But i looked at the mac adresses and they're different. now its back to 4. should i worry or not? and what i can do to prevent this from happening ever again.

Hello mino538,

Philbert makes some really good points!  If the issue is still eating at you, I suggest you factory reset the device. Ensure you select WPA2-PSK as the security version. Make the admin and WiFi passwords at least 20 characters long. Use a password manager to manage your passwords. Don't re-use passwords anywhere. Computer power nowadays means that an eight character password can be cracked in three hours. I hope this helps you put the thought of being hacked behind you!  Mike

Do you have any Apple Devices running IOS14 or higher? 

 

If so they have a setting by default that it randomly changes the MAC address of the device when connected to WiFi networks, means this will temporarily appear as a 2nd / 3rd / 4th device on the network with different MAC addresses.   We disable this feature as it causes all sorts of issues for wireless controllers

 

Its also available on Android 10+ but believe its OFF by default, certainly not as prevalent an issue for android.

What version of Android are the devices?  If you have the MAC address written down or recorded we could trace the vendor and might tell you more

 

I would say its unlikely anything to worry about..

@MikeFdes thanks for the tips,  but i have a question  what about the router interface password?  it usually has a very weak password,  like admin or something like that i changed it something a little bit harder but with only 5 characters. is it good?

@mino538 That password is weak by modern computing standards. That number of characters takes about three seconds to crack. I would change both the router interface password and the WiFi password to something between fifteen and twenty characters long.

 

https://bitwarden.com/password-generator/

 

That link above is to a password generator. Use that to set a stronger password. Start using a password generator to store these passwords. That'll also ensure you don't reuse any passwords.
