In principle, a good device with many setting possibilities. However, it is very annoying that the provision to the factory settings when you no longer get to the web interface of the device (for example, because one no longer knows the fixed IP or has forgotten the password), is very inconvenient! One must first take a computer with a serial port connection raise (!), Then you have under Windows build with HyperTerminal session to the device (the HyperTerminal program was last shipped with Windows XP and is not since Windows Vista longer part of Windows ). After all, one does not have time for about 1 second between turning on the switches and pressing Ctrl-B to enter the appropriate boot mode from the device, where you can do that provision. Very difficult when you are alone (in particular, because the device has no power switch ...).
