I need to remove some devices from my devices list in my Router. I have not seen a way to do it. I would like to avoid changing the password in order to confirm or not if someone is using my wifi. 

Thanks!

Depending upon your RG/Router, you can probably get the device's MAC address from the DHCP server, then go into the MAC Address filtering and block traffic to/from that MAC address.  That should prevent the device from accessing your internet service.  Of course, if the person is persistent, they could alter their device MAC address and re-connect again.  The simple solution here is for you to determine teh MAC addresses for the devices you want to allow, and set the filtering rules to default everyone to no-access, then add exceptions for all your devices you want to allow to connect.  I used to use this method in the past, and it worked quite well.
