With the designation "International", the device should actually also work on standards of boxes operated abroad. In my experience, certain cheaper or older repeaters paralyse the entire Wifi network and even render the LAN access of a box unusable (e.g. SFR, Orange France)! If the device is operated or sold abroad, it is advisable to read the technical data carefully to avoid inconveniences or incompatibilities.

To be precise, I would have to guess, because I don't have an answer to this question. I use the device to extend the existing WiFi and have not experienced any problems so far.

International= Weltweit
