Hi there.

So my household currently has Deco installed for WiFi extension and a few Ethernet connections. I also have a TP-Link powerline adapter (close to TL-PA4010) which I have linked together and use to connect to the internet.

The problem is, I don't have access to the deco app. So whenever the internet is being slow for the one who does have access, they kick me off and I have to change my MAC address to reconnect. I have paired my two power lines and disconnected deco to check if I still have connection (I do) but I still manage to get kicked off. I think my power line is still connecting to deco even when paired to the other/flipping between the two? Because I sometimes have doubleNAT issues. 
 

If someone could help me in connecting my power line only to the one I want, I'd be immensely greatful.
