Unwanted device on my wifi

dandpgallant170

Hello. 

I have an unwanted device on my Wi-Fi network. it changed names after I tried to kick it off using FING . first it was WPS access point ( atheros ruby ) then to WPS access point (atheros APxx) and now it's Hiltron technology (APxx). Address stayed the same. The first time kicking it off worked for 12 hrs then it came back and now can't remove it

I tried logging into my router admin online and I put the MAC address in my " device filter " under the blocked list -security , still didn't work.

My internet provider can't see it I can just on FING app . The IP address is outside of my (range) according to my router admin page. So the first 7 numbers of IP are the same as the rest of my devices. But last 3 are outside the range. 

Any advice would be helpful.

@dandpgallant170 , first thing I would do is to change the wifi password.  Something more complex than you had before....  See if that keeps it off your network.  Also change the wireless router admin password to something complex just in case that individual had it.

@Marc Yes but I worry if they are seeing my laptop they'll see the new password. Am I correct ?

if your laptop is compromised yes.  But then you have bigger issues then just the router.  In that case you could reset the router by connecting to it with your smartphones browser or app and re-set it as described.  Do not add your laptop back.  

If you're sure the laptop is compromised, then you will need to reset your laptop, basically putting it back to its factory settings.  Do not restore the OS or any apps from a backup.  You will need to add them back via trusted sources like your manufacturer supplied CD or certified App Store etc.
