EW-7438RPn
v1 and v2:May
I use the firmware of EW-7438RPn v2 on EW-7438RPn v1?
No,
if your EW-7438RPn is hardware version 2, the device will
fail if you upgrade it with the firmware file of hardware
version 1. If your EW-7438RPn is hardware version 1, the device
will fail if you upgrade it with the firmware file of hafdware
version version 2.
