Firmware upgrade for TL-PA4020

2021-01-04 18:10:35

Model: TL-PA4020P KIT

Hardware Version: V1

Firmware Version: 1.1.0.844-01_402011_140208_001

Hi Folks

I have a PA4020 which is on firmware version 1.1.0.844-01_402011_140208_001 and I wanted to upgrade it to v4 so I downloaded the update from https://www.tp-link.com/uk/support/download/tl-pa4020p-kit/v4/ and managed to upgrade the base Unit, but the remote unit keeps failing and that's the one I'm actually connected to via a network cable.

The files I have selected are:

4020PV4_1.4_EN50561.pib

mac-release-X.nvm

Any ideas why that might be happening?

Cheers

Hi,

Normally V1 could not update the firmware of V4.

And could you please double check both of the TL-PA4020P are V1 or V4?

By the way, since you have updated one of them already, could you please check what is the current firmware of this one?

Thank you very much and wait for your reply.
