My router is downstairs in my basement. I run this wifi extender to get Ethernet in my room upstairshttps://www.amazon.com/TP-Link-Extender-Pass-Through-Outlet-TL-WA860RE/dp/B00PEW7V7E/ref=sr_1_8?ie=UTF8&qid=1481158041&sr=8-8&keywords=tp+link+wifi+extender. But, it's giving me slower speed than the regular network. I have tried to plug in the ethernet cord i get from the extender to run a router but it dosent work. Do i need a modem connection to run a router in my room? If so, can i get one without buying another connection?
