  @Jeremy_12  Thank you very much for your reply, as always TP-LINK support is kind and active in the forum.

First detail, why can't the Omada Controller find the latest firmware for the ER7206 V2.20?

Shouldn't this be automatic?

Why do I have to do it manually?

I already made a post here that Omada in Brazil is not updating some EAPS, as per the LINK below.

https://community.tp-link.com/en/business/forum/topic/859290

Will this be recurring, will Omada always have failures when updating its equipment, forcing us to do it manually?

But I tried to do it manually, here are the screenshots.

I downloaded it.

Performing the manual update

When I upload the downloaded file from the TP-LINK website, for both the ER7206 V2 and V2.20, the file doesn't load; it gets stuck in an infinite loop (the loading circle keeps spinning), preventing me from pressing the UPGRADE button.

I used a later firmware version than the one installed, which is 2.2.7.
