How to block someone form using my wifi?

September 9, 2018 at 08:11:48
Specs: iPhone
I use a digisol router DG HR-3400. At first when I went to Active client table I saw an other device also connected. So I changed my password and went to Wireless advanced ➡️ Mac filtering and put my MAC address. For a while then the other device wasn’t shown. After few hours again I see the same device connected. Please help. I switched off my WiFi for a while but I won’t help me. I need to use it. Please help me

How many devices do you have with wireless capability? Computer? PC? Cell phone? Any other devices like an Echo, TV? etc?

Doing the best I can here... And remember, there's always more than one path to success. :)

Are you using WPA2? Difficult password or passphrase?

Any indication as to what that device is?

Are all your computers and printers etc powered down; and television systems which might be Wi-Fi enabled also powered down?

I would try to determine the source of the other WiFi connection.
First by looking at its name, second by shutting down all your
WiFi enabled devices, as trvlr suggests, one-by-one, and
third by moving your WiFi receiver around to determine where
the signal goes out of range and where it is strongest.

You should be able to see the MAC address of the unwanted device. Using that and a "MAC address lookup" (I use the following one)

you can determine the vendor of the device. This should at the very least help you figure out if it's yours or not.

I am surprised filtering all other MAC's except yours didn't work. This makes me wonder if you don't have an issue with your router. In any case, check for a list you can add the offending MAC to that prevents each MAC in the list from connecting. If filtering didn't work, try denying it a connection and see if that doesn't work. There's no guarantee your router can do this, but it's worth looking into.

I would also suggest updating the firmware on your router to the latest if it's not already at that level.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

Are you sure that you are looking at devices only on Wifi and not network in general? You may have hardware devices connected that will show up with MAC address as a network device.

You have to be a little bit crazy to keep you from going insane.
