Powerline Adapter setup

I bought four powerline adapters (Monoprice Ethernet over Power Powerline Converter 1Gbps).

I installed two, and they work just fine.  When adding the next 2 it doesn't pair for some reason.  I've attached a pdf of a representation of my network is setup.  My house is WIRED for CAT5 (not 5e, or 6).  Thus, I've introduced the 1Gbps Powerline adapters.  My modem/main router is located in basement.  

My FIRST pair of powerline adapters (which are working fine as a "PUBLIC" network) are connecting the "Floor 2 Router" to the "Floor 3 Router".  Basically, the Floor 2 router is plugged (via powerline) into a LAN port of the Floor 3 router.

Since the Floor 3 router is CURRENTLY connected to the Basement Router (e4200) via CAT5, I want to replace this connection with the Powerline adapters so I have at least 1Gbps of flow between my Basement router (e4200) and my Floor 3 router (which would subsequently server my Floor 2 router via the current Powerline connection).

The problem is, when break the Floor 3 Router and Basement Switch connection and replace it with 2 powerline adapters, they won't pair.  In my head I'm thinking that this electric circuitry IP setup:  comcast cable ---> cable modem ---> basement router (e4200) ---> HP switch ----> Floor 3 router ---->  Floor 2 router, is conflicting with the new pair that I add to the network when I connect (via Powerline) the Floor 3 Router to the "backbone" Basement HP switch.

All four devices are on a "public" network.  I'm sure I've thoroughly confused the issue, but hopefully someone can help!

From this Netgear post:

"If you want to have two independent links between pairs of nodes, it can be arranged by setting the encryption keys for each pair to different values"

Did you set up different encryption?

No, all four are on the same "public" network.   How can I do so using MY adapters?  Is that the answer?
Here is a Netgear guide for setting encryption keys. I think in your case, you should try it as I think this is what you might need.

Does it matter that I didn't buy Netgear devices?
You can purchase the brand of your choice, but get the documentation for setting them up.

?? I purchased the powerline adapters in my OP... I thought that was what you were responding to.  I don't have Netgear adapters...

Thank you both.  I was able to download the Utility that allows me to create Private networks.  I created a private network between the Switch and Level 3 Router, and also between the Level 3 router and the Level 2 router.

Only thing is, the bandwidth seems really low now.  Between 10-15Mbps.  I was getting 50Mbps before.
You are very welcome and I was happy to help. Unfortunately I do not have a pair of these to test.
