I'm attempting to update from firmware 3.26.9 to the latest 3.27.9 on the AP9834 USB Wifi units on my SRT1500XLA and SRT3000XLA. I have placed the firmware ism file onto a FAT32 USB drive and attempted to update from both the UPS USB port and the NMC3 USB port.

In both cases, the update fails citing "Invalid File". I have confirmed in the logs the USB drive is detected correctly.

I am unsure how to proceed with updating as the documentation around wifi firmware updating is essentially nonexistent and there do not appear to be any intermediate versions I can attempt upgrading to.
