All you really need to do is use *any* Linux machine that has both a hard 
Ethernet and a Wireless Ethernet connection (an older Laptop or a desktop with 
either a PCI Wireless or a USB wireless dongle) and configure the hard 
ethernet (eth0) and wireless (wlan0) into a bridge device.  A Raspberry Pi 3 
is a cheap, low-power option -- all of the hardware for $35 in a very small 
form factor with no moving parts (eg rotating rust, fans, etc.).
