I usually try to read about updates for my AX1800 here:  https://www.tp-link.com/us/support/download/archer-ax1800/#Firmware

I see you have the AX1800.  So do I.   Are you referring to the update that just came through to the router this week?   I don't see it on the website yet.  I don't know why, but sometimes the updates hit the router before they're listed on the website.  But within the router's firmware update page, there's usually a link to 'see whats new' before you install it.

BTW,I see you listed yours as version 1.  Mine says its hardware version 1.20 so be sure to double check your version before installing firmware.  I normally just wait for the router to tell me there's a new version available. 

@FixMacs Thanks for your note.
