Archer MR400 firmware does not match hardware version
Hello there,
I have an Archer MR400 with hardware version v4.20 (at least this is what is written on its label on the bottom), but the admin page says: Firmware Version:1.0.0 0.9.1 v0001.0 Build 210610 Rel.67239n Hardware Version:Archer MR400 v4 00000001
Here it says that hardware is v4.
Firmware seems out of date (since I don't know the proper hardware version I downloaded both v4 and v4.20 firmwares and those version numbers are higher). If I try to upgrade firmware via the admin page or Tether app it says "Your firmware is up to date".
Help me please - what is my real hardware version and why cannot I upgrade firmware to a (seemingly) newer one?
