I am using Raspberry Pi using Raspbian which is just Debian.I would like to bridge from the primary WiFi network router that connects to Cox Cable to my cabled router here for my subnet to have reliable internet access.   It needs to be a WiFi-to-Ethernet bridge.  I have set /etc/networks for a static address for the USB wlan1 with the external adapter and hi-gain antenna.  wpa_supplicant is configured to log in to the master router properly.  So right now it is set up so I can login to the proper network with the password, on external wlan1. Static address is set in /etc/networks. Gateway and nameserver are OK. I can browse web pages, etc. The missing link is to bridge this to the eth0 port so my router can connect also, to provide service to my subnet.No need for any extra network services like routing or nat or dhcp, etc.  Just a simple bridge.  Can anyone please point me in the right direction to make this happen?Thank you in advance for any help.
How do I configure a network interface bridge from WiFi to Ethernet with Debian?
debian;wifi;ethernet;bridge
For configuring a bridge from ethernet to wifi, it is as simple as doing in your /etc/network/interfaces:auto eth0allow-hotplug eth0iface eth0 inet manualauto wlan0allow-hotplug wlan0iface wlan0 inet manualauto br0iface br0 inet staticbridge_ports eth0 wlan0    address 192.168.1.100    netmask 255.255.255.0Replace the IP address with something more appropriate to your network.If you prefer the IP attribution done via DHCP, change it to:auto br0iface br0 inet dhcpbridge_ports eth0 wlan0After changing /etc/network/interfaces, either restarting Debian or doing service networking restartWill activate this configuration.You will have to make sure for this configuration to have bridge-utils installed. You can install it with:sudo apt install bridge-utilsFor more information, see: BRIDGE-UTILS-INTERFACESThe wlan0 interface also has to be condigured to connect to your remote AP so this configuration is not be used verbatim.
