Hi all,

I have recently purchased 4x TL-PA9020P and have them connected to 4x Google Wifi APs (1x AP is set as router and others are APs only).

Currentl looks like this: 

• ISP Router (bridge mode)
• >>> Google AP (Router Mode)
• >>> 8 Port Switch
• >>> No.1 TL-PA9020P (Primary) 
  • >> No.2 TL-PA9020P >> Google AP
  • >> No.3 TL-PA9020P >> Google AP
  • >> No.4 TL-PA9020P >> Google AP

What confuses me is when I look at tpPLC and it shows me the topology it shows me that No.4 TL-PA9020P is the primary communicating out to 1,2 and 3. 

The only logic I can think of (because the primary appears to change around on tpPLC) is that tpPLC is drawing a map based on my laptops current path of connectivity. If that is the case that would make sense but otherwise I would of expected to see No.1 being the primary and has arrows pointing to all the other power line adapter (2,3 and 4).

So Question no.1 is that correct? Is the tpPLC mapping by route traversed? If it is not correct how do I mark the No.1 TLPA9020P to be the "Primary"/ Master.

Question no.2 which I also think I know the answer for but seeing as these devices are MIMO should I have two network links coming in from my switch into my first "primary" TL-PA9020P or is that going to create a loop?

Thanks,

Ger
