 .. note:: The typical configuration is to use the Bullet in *Router* mode with a DHCP server, as to automatically address an IP to each connecting device. If this is the case, this configuration can be performed in the "Network" tab and the changes can be applied with the "Apply" button. After a short connection drop, you may connect to the access point's WiFi network and access it with the IP specified in the "Network" tab. As the Router mode isolates the LAN and WLAN interfaces, connection between wireless devices and the Raspberry's Ethernet becomes impossible. Thus, in the case of the Platypus boat, **the radio must be configured in Bridge mode**.

 Testing the connection between WiFi and the Raspberry's Ethernet

-As there is no DHCP server, the Raspberry and WiFi devices must be manually connected to the Bullet. Once again, this can be done with the ``ifconfig`` command in Linux. For the Raspberry, the interface used is the Ethernet (e.g., eth0). After connecting the LAN cable on the Raspberry's Ethernet port, run:
