Gents, I'm experiencing odd things with the Device Manager view of the XR500: 1. Sometimes when I try to select a device, from either the Device table or the Device tree I get the error : TypeError: undefined is not an object (evaluating 'a._id=null') 2. The information in the Device table is not always consistent with Device Settings that are visible after selecting the device. For example in the Device table the IP address of a device is given as N/A, while in the Device Settings window the right IP address is given. Another example is a device that has in the Device table the Connection Status Offline, but when trying to delete the device I get the error “Error: Unable to delete device because it is online.” 3. I want to delete a device from the Device table list. The device itself has been switched off for more than an hour, but the XR500 is still showing connection status Online, and as a result the device cann't be deleted. Does anyone has suggestions to solve these issues, or has any workarounds?

I assume you've tried all of the steps that were suggested earlier in the thread? Restarting, resetting if neccersary. There hasn't been any firmware updates since then but one is in final testing.

What browser are you using? Try a different browser like FF or Opera. Has a factory reset and setup from scratch been performed?

1. As above, what web browser are you using? Do you see this issue in Google Chrome?2/3. I'm wondering if the browser isn't updating the information on the view that's not shown properly, do you observe the same behaviour on Chrome? Is the device in a standby/rest mode? If so packets every so often will be transmitted, keeping the connection alive so you can't delete it.

Gents, Up to now I was using Safari on a Mac, but today I tested both Firefox and Chrome (all running on Mojava). All three browsers show exactly the same behaviour. So I'm afraid it has to do with some issues in DumaOS. Both turning off the power, and removing the ethernet cable of my Airport Express still didn't result in getting it in the "Offline" status. I'm a little reluctant to reboot the XR500. I gave all devices readable names, and I'm not sure if this information will be preserved after a reboot.

Names should persist during a reboot.
