These powerline adapters AV1000 have the Broadcom BCM960355 chip. Therefore you can use regardless what supplier of your powerline device is the same firmware. Some suppliers do not offer latest firmware.
Broadcom firmware is a ggl file which is a tar archive. With a viewer for compressed archives you can open this file and see what firmware is inside it.
The latest available firmware file is fw_upgrade.14077.rakis_A1_no_diag.BCM960355.bin. The number 14077 is the version.
If you use different powerline adapter types and different hardware versions the powerline adapters have different default firmware versions when bought. In your powerline network due to the different firmware versions and even older firmware versions you will not get the maximum transfer speed and stability. It was measured that with the latest firmware sometimes transfer speed doubles.
Via the D-Link PLC utility with this firmware even the D-link Dhp-601av (2x Dhp-600av) Powerline Gigabit Starter Kit or other work great with the TP-Link adapters together.
