Model Id: R6700v3 disconnects from browser after applying a Device Name edit

I wanted to change the device name for a component on my LAN

I was in the Attached Devices screem; I selected 1 line, clicked Edit, changed the name and clicked Apply

The Attached Devices frame went blank but did not refresh

The browser page would not refresh

After i closed the browser and reopened the Nighthawk would not respond to the browser -- that IP not responding

the Nighthawk would not respond to a ping

After power cycle, the Nighthawk responded again

The Device name change did occur and could be seen after the Nighthawk came back online

Details ...
