You can use a raspberry pi 3 to connect to WiFi. Ethernet from Xbox to Rpi. A bonus to this is you can install xlink kai server on the pi also for online gaming. Or there is this; Vonets Wireless Mini Bridge dongle, WiFi Bridge Cable Convert RJ45 Ethernet Port to Wireless/WiFi Dongle, 300mbps WiFi Hotspot Signal Booster Extender Amplifier VAP11G-300 https://www.amazon.co.uk/dp/B014SK2H6W/ref=cm_sw_r_cp_apa_i_nAstEb7JZ4PE6 It requires a pc to set up initially but then just works

I have never had any problems, when I first used it the only downside was plugin compatability!

I use this build; XBMC(4xbox)-14095-XLinkKai It is the last xbmc to support Kai from the console and with Kai running on a raspberry pi you can have an all in one solution
