Hi all, Just got these powerline adapters and they are driving me crazy. As soon as I connect two devices to my router (through the powerline adapter), both ports flash rapidly in sync and the router reboots itself after a little time. If I use one port at a time, I can do this without issues on each port. So they are both definitely working, just not when I try two devices at once.Even if a device is not connected on port one of powerline adapter two, if I plug port one of adapter one into the router and the other port is in use, it still happens. Please can anybody advise? Cheers

Are you connecting two cables from the router or just one?

Two. Although with them both connected it seems to screw up the router.At present I've only just one device going from the powerline to the router until I can work out what's going on. I have a Sky Router. I'm not sure if that may be or at least be contributing to the problem.

I'm about to purchase this kit, but seeing the problem you have, I'm going to make sure your problem is sorted out first.

I have two inverters (Solar Power), and need to send the signal through my router to the inverter manufacturers site; of course both must be sending data at the same time. If I can't do that, then this TL-PA4020PKIT is not what I need. 

My other question regardless of this problem is if I also need tho connect the two Ethernet outlets on the receiver unit connected to the router or just one is fine??

Sorry I haven't been of much help at the moment, but if I find out I will be back with the answer.

Best regards and good luck

@SpanishFlyer 

Hi,

You could use both Ethernet ports on the receiver(the one not connected to the router).

And for the master adapter connected to the home router, only one needs to be connected to the router, the rest one could also be used for other Ethernet connection.

If there is any misunderstanding, please feel free to post it here.

Thanks a lot!

@TP-Link I have this exact kit, and am unable to use two Ethernet ports at once.

One works, I'm currently writing from this connection: Modem > Router port 1 > PLC1 > PLC2 > PC.
All is fine and dandy, but when plugging in a second Ethernet cable (router port 2 to second ethernet port on the AV600 device), the whole network instantly dies. Can't connect to router (192.168.0.1) which doesn't transmit data anymore, and the AV600 Devices disappear from  tpPLC utility software.

 

Windows troubleshoot informs that it couldn't assign an IP address, and I couldn't find a newer firmware on the site.

 

I specifically got the 2-port variant for getting internet to two different devices, hoping there's something I'm missing. Any help?

 

Regards,

Rob

@PapaRob ,

 

I have exact SAME problem, BUT even with newer WPA4220, i want to do Link Aggregation via WPA4220 with BOTH ETH Ports on C3150 Router! sad

I have big House SO my setup is little bit "complex" with 3x PA, 4x Router, 1x SW like this! cool

2. Floor INET <=> Modem <=> AX73 Router <=> PA4010 <=> 1. Floor 

2. Floor Terrace C6 Router WDS <=> C7 Router, i needs to keep SAME Wifi for IoT Devices on 2. Floor

1. Floor PA4010 <=> C7 Router <=> WPA4220 <=> C3150 Router <=> TP-Link SW

 

Everything is working fine, until i connect 2. ETH Ports from WPA4220?!

@TP-Link Please could You explain what is the exact problem here? WPA4220 LAN Ports have SAME MAC addresses OR what?

 

THX & BR

Hello@Kali777, we can't set up a Link Aggregation on a Powerline unit,  that could cause a network storm. 

In your scenario, please do not connect to routers(APs) to WPA4220 together.
