tftp/MacOS not working with WR902AC

[Gary]

Just bought a version 3.8 WR902AC. Using MacOS Monterey, set up the TFTP server per instructions, tried to flash and didn't work. No errors, no messages, no nothing, other than the WR902AC booted with its factory fw. tried the other ip address, same thing. tried again, and again. same thing.

I do note that the factory sw does have a manual firmware function. Just point it at the file and go. Normally, I'd just go ahead and do this, but want to make sure I don't brick the device. Will this work? anything special I need to name the file? Any suggestions on troubleshooting the TFTP process?

thanks.

Impatient as I am, I went ahead and tried to upload the tp_recovery.bin file. I got an error:
Error code: 4503
The uploaded file was not accepted by the device.

So not sure what to do now.

A little more about my configuration. WR902AC is connected to an unmanned switch on my home network, my MacBook Pro is connected to the same switch. My network IP addresses are 192.168.108.xxx. Mac firewall is off.

Do I need to disconnect from my home network and connect the WR902AC directly to my Mac, and manually set its address to something on the 192.168.0.x addresses? Only other thing I can think of...

A tiny bit of progress. I found a 3rd party program called "transfer". It at least has some logs, it is showing a timeout for the transfer. It appears the request is coming in, and the file name is correct. As to why the timeout, I still don't know:

i got this working! did direct connect of ethernet cable to my mac, manually set mac ip addr to 192.168.0.66, and it completed the file transfer. It would have probably worked without the "transfer"app, but with the app i got confirmation it successfully transferred the file.

Now, on to licensing issues, my upgrade license I purchased for my old 3020 v1.9 won't work...
