What I would do and I have had issues with my 1941w when upgrading. I would delete the image from flash and install the rcv image and have the AP801 join and download the new firmware. That code you are running is a TAC release and maybe the image is corrupt for the AP801. You will have to test that by deleting the image and having the AP download the code again.
This is how I fixed my issues which you are having. Some beta codes I have used never worked because of the AP801 image being corrupt. The v7.4 both versions, v188.8.131.52 and v184.108.40.206 all work fine with my AP801.
