http://www.belkin.com/us/support-article?articleNum=4736 finds some USB adapter and in short, only the Samsung USB sticks are supported. You can't load a driver since there is no PC inside to support the drivers Belkin issued.

So what to try next? Either the Samsung stick or one of the many WiFi to Ethernet client devices. Figure 20 bucks for that. Example at https://www.amazon.com/TP-Link-Wireless-Repeater-150Mbps-TL-WR702N/dp/B007PTCFFW (may have to buy used or another model)
