Deco M4 units have different firmware versions
Deco M4R (US)
Hardware version: V2
I had purchased Deco M4 - 2 Set. I had to replace 1 unit because ethernet was not working. I got the replacement unit and it seems that it is stuck on firmware version 1.4.3 Build 20200918 Rel. 74289 which is causing issues (internet down for 10 seconds, slow speed) with my other deco which has firmware version 1.5.0 Build 20210511 Rel. 34580. I am unable to find the 1.5.0 Build 20210511 Rel. 34580 version on the tp-link website. The unit was purchased and replaced in India. I checked the latest version on Deco app and web ui as well and it states that 1.5.0 Build 20210511 Rel. 34580 is the latest version.
Apparently, I am unable to attach the screenshot. The link to the screenshot is https://1drv.ms/u/s!ArAVjZ6YdarZgeku_PptzuRyTHMtkg?e=fsRcGB The one with 1.4.3 is the main deco. I tried switching the units, still the 1.4.3 is unable to upgrade.
Can anybody please send me the file containing 1.5.0 Build 20210511 Rel. 34580 version?
