@Marvin_S Hey, the Indian Website firmware isn't updated yet, soo I am stuck here. Is there any other way to obtain the firmware? I mailed the TP-Link India about this, but no response yet. Also the CC is clueless about the firmware as well, saying it got bricked coz I used the Tether app to update the firmware, which caused it to just outright refuse to work by bricking it somehow.

  @Marvin_S Hey, So I couldn't find the Indian Variant of the file. The current version v1.20 (US) is causing Wi-Fi slowdowns on my 5GHz band. Is there any other way to obtain the firmware file?

@IfranAli I found the exact version of the firmware which is installed on my TP-Link Archer AX23(IN) v1.28 on the Brazil page https://www.tp-link.com/br/support/download/archer-ax23/#Firmware

It has the same build and rel number as the version which was installed on my router via online upgrade.
The downloaded firmware also mentions several countries AX23_us_ca_tw_sg-up-ver1-1-1-P1[20240822-rel44461]_2024-08-22_12.25.33 but not India.

 

Online installed version

I haven't tried installing this myself, so proceed at your own discreation.
