New Firmware 1.4.0.18 released

I solved the problem by changing the static IP address of my computer. Not sure why that fixed it. But I have a hunch. 

I originally set up the Orbi from this computer, connected to the router by ethernet, with a static IP address of 192.128.1.250 ... And almost every time I tried to list the attached devices in the web interface, I would get that message about another device being logged in. Other pages in the web interface seemed okay. When I used another computer on my network, also connected to the router by ethernet, but with a different static IP address, no problem.

So I tried changing my IP address to 150, then later to 251. I have not had that problem since. So I wonder if setting the router up with a computer with a static IP address caused some kind of problem where the router remembers that IP address, or creates some process using that IP address, which then conflicted with my computer's IP address. Because, along with this error, I would sometimes get an error from my computer saying there was another device on the network with the same IP address.

So seems like some sort of glitch in the firmware possible related to initial set up from a computer with a static IP address.
