PLW 1000 - Connecting other networks to mine - MASSIVE SECURITY RISK

Question

I live in a condo/appartment block. I bought the powerline adapter and connected it to my network. When checking the ISP Modem, I can see other ISP Modems on my network, through the port where the Powerline adapter is attached to. I have followed this article:&nbsp;
https://kb.netgear.com/29923/Changing-the-DST-network-encryption-key
&nbsp;
To change my encryption key to make sure it wasn't the lack of encryption. I have also turned of the Wireless component as I do not need this. I am still pulling other peoples networks!
&nbsp;
When I release and renew my IP configuration, I am given a Private network address, with the Gateway of another Modem!!!
&nbsp;
Please help! I work from home and this is major risk for me!

&nbsp;

What do you mean "pulling other peoples networks"? You can see their wifi? You can see them on the wired LAN network?
&nbsp;
I don't know about anyone else, but this looks more like the rest of the people on the network should worry, not you.
&nbsp;
You may be able to see them, but can they see you?
&nbsp;
What else is on your network? Router? Modem?

By 'Pulling other people's networks' I mean, I can see their router's/modems on my network. When I ipconfig /release | ipconfig /renew I am able to connect to their network, but still using the name of my wifi. I can also see their devices on my network when running a scan using Advanced IP Scanner.
&nbsp;
If I can see them, connect to their modem's and get to their modem's gateway address', I'm pretty sure they can see me.
&nbsp;
On my network, I have my ISP's modem/router which connects to the Netgear device, and then the other netgear device on the other side of my apartment. There are no other devices.

I see no answer to these questions:
&nbsp;
You can see their wifi? You can see them on the wired LAN network?
&nbsp;

Any evidence that they can see you? "Pretty sure" won't stand up in court.
&nbsp;
What happens if you remove the Powerline plug from the network?

Yes, but what is it?

My apologies.
&nbsp;
You can see their wifi?&nbsp;
&nbsp;I can see their wifi SSID in the list of possible connections in the Windows Network Connections. When I change the IPConfig with the release and renew command it does not switch me over to their SSID. It stays on my SSID, but the IP address and Gateway address changes. I can then access their Modems and see their WIFI SSID is completely different to the one I am connected to.
&nbsp;
You can see them on the wired LAN network?
I can see the other modems on the wired LAN network, the modem can see them as if they were wired in from port 2 (port 2 on my ISP's Modem/Router is where the Netgear Device is plugged in).
&nbsp;
Evidence that they see me?
I do not know if this is evidence, but there is a device, which is NOT mine, which is connects to my network only when the Netgear device is plugged in. When the Netgear device is removed, the other connecting device dissapears.&nbsp;
&nbsp;
When the netgear device is removed from the network:
I can no longer see any of the other networks on my LAN.
&nbsp;
What is it?
It is a Ubee Avanced Wireless Voice Gateway&nbsp; -Model DVW32CB

You will see all wifi SSIDs in range unless the people who own them deliberately hide the SSIDs. That is how wifi works.
&nbsp;
But can you connect to those sources?

&nbsp;

Is that with or without the Powerline plugs. Or can you see those devices with the plugs disconnected?
&nbsp;
I am still trying to understand how the Powerline devices play a part in this scenario. 
&nbsp;
If you see these devices with the Powerline plugs removed, then that is where you need to work out what is going on.

&nbsp;
That looks like a Modem/Router as well as a"gateway" for a phone.
&nbsp;
I assume that the Powerline&nbsp;plug is connected to that.
