You can operate the Wi-Fi repeater on the campsite, but it will only work if you connect to the campsite's existing Wi-Fi. If you do not have the option of making settings on the campsite's main Wi-Fi network or logging in there, the repeater cannot amplify the signal on its own. It needs an existing connection to the main Wi-Fi network to extend the signal. Without such a connection or login to the campsite Wi-Fi, the repeater will not work automatically.

Exactly, if you have the WLAN name and password, you can connect the repeater as normal and boost the signal. You don't need to change anything on the camping device.

In other words, if I have the login word and password, can I use the Repater?
