Firmware issue with Archer AX21
I have an Archer AX21. According to the app the hardware version is 1.20. I updated the firmware via the app. It says that it is up to date at 1.2.1 Build 20201202 rel.76564(5553). If I go to the TP website the Firmware available for AX21 1.20 is Archer AX21(US)_V1.2_201118 and for AX21 1.2 (no zero) the firmware is Archer AX21(US)_V1.2_201202 (which seems to correlate to the version my app has downloaded). So long story short, the app seems to have installed the firmware for 1.2 on my 1.20 router.
Normally I'd say who cares if things are working, but I have an issue with write access on my attached USB hard drive (on a Catalina Mac) and I am wondering if that could be firmware related. Everything else as well as read access to the drive seems to work fine.
Any thoughts?
