Current firmware :
TP-WPA4530 (TL-WPA4530(UK)_V1_160426) from tpPLC (1.1.0.871-04_453011_150324_002)
TL-PA4020 (TL-PA4020P_V1.2_UK_160311) from tpPLC (1.3.0.2134-00_402191_160311_903)

Default firmware RX 100~110Mbps 50~Mbps (lots of dropped packet)
Current firmware RX 110~120Mbps 60~70Mbps (Smooth with Ferrite Choke on neighbouring power strip to reduce RFI)

Current Setup:

Gigabit Router > TL-PA4020 > TP-WPA4530 > PC + Laptop

Problem:
When I try to connect 2 TL-PA4020 Fast Ethernet Port to 2 Gigabit port on the router, the router hangs up because of the broadcast storm. *silly me*

Question:
1. Can I link aggregate 2 TL-PA4020 using a easy smart switch or smart switch to get 200Mbps to my Powerline network?TL-PA9020P KIT

Gigabit Router > TL-SG108E >> TP-WPA4530 (2 Ethernet Port) > TP-WPA4530 > PC + Laptop

TL-SG108E support Link Aggregation by software work on PLC devices?
or
Does PLC devices support Link Aggregation?

2. If I introduce AV1200 (TL-WPA8630P KIT) to my powerline network. Will my overall powerline network upgrade to AV1200 and TP-WPA4530 kit will max out at AV500 speed?
or
my whole powerline network bottleneck at AV500 speed?
