Model: Archer AX21  
Hardware Version: V4
Firmware Version: 1.1.0 Build 20230725 Rel. 55602(5553)

I am trying to downgrade the firmware on my AX21 to Archer AX21(US)_V4.6_1.0.5 Build 20221116, however when I try to do the Local Update option on the tplinkwifi.com admin UI I get an "Upload error." Specifically, I'm trying to upload the "AX21v4.6_us-up-ver1-0-5-P1[20221116-rel40103]_2022-11-16_11.08.35.bin" file from the TP-Link firmware website. What can I do to be able to have this firmware successfully upload? Thank yOu!

I do not see a note that says the FW can't be downgraded so that should not be a cause of this concern. So a few things i would try.  

 

1.  Download the file again from here:  

2.  Make sure you have unzipped the file, as you will not be able to upload from a zip file in most instances  

3.  upload for a different folder to see if it may have been a location concern
