The latest TL-PA9020P KIT(US) V3 firmware listed on the TP-Link site is:

3.2.4_902103_170627_902

I updated one of my adapters thinking I was getting the latest firmware. But when I checked the other adapter's version, it showed:

3.2.4_902103_180511_903

The numbering suggests the built-in version is actually more up to date than the one available online!

Is 903 actually the latest version? If so, how can I obtain it so that I put back 903 firmware on the adapter that got "downgraded" by mistake?

Thanks!
