WLAN Pi – Setup a Wi-Fi Hotspot
Thanks to Florent Lassia, we were able to configure the Wi-Fi NIC to bride to the Ethernet NIC. In the Hotspot mode, you can now have your Wi-Fi hotspot running, connect a client device to that Wi-Fi network and receive network connectivity to the LAN if your WLAN Pi is connected to the LAN via its Ethernet interface. We have detailed how to do it on this blog post: https://www.semfionetworks.com/blog/wlan-pi-bridge-wi-fi-hotspot-to-ethernet-interface
