Configuration

Once logged in, we recommend clicking the "Check for updates" button in the QuickSet menu, as updating your
RouterOS software to the latest version ensures the best performance and stability. For wireless models, please
make sure you have selected the country where the device will be used, to conform with local regulations.
RouterOS includes many configuration options in addition to what is described in this document. We suggest to
start here to get yourself accustomed to the possibilities: http://mt.lv/help. In case IP connection is not available, the
Winbox tool (http://mt.lv/winbox) can be used to connect to the MAC address of the device from the LAN side (all
