I've been using the AX11000 router for a couple of weeks now and I have been very happy with the reach and speeds in my house. One thing that really has me perplexed is that I can't seem to get Time Machine to work. I have followed the instructions provided in the documentation, but it doesn't work as planned. I keep getting an error message that says, "You do not have the necessary read, write, and append privileges on the selected network backup disk."

I have searched the forums and seen folks post about similar issues. All have said they found workarounds, but never post what those workarounds are. I was hopeful when one post said that a trouble ticket was sent to network engineers, and the engineers sent over a custom firmware update. The OP said they never used the firmware update. 

Someone please help! I'm at my wits end and ready to take this router back.

Thanks.
