As gamers we need the best net connections possible, and while we prefer the super-reliability and ubiquity of (Intel) Gigabit Ethernet in our ROG motherboards and ASUS RT routers, sometimes running a wire is not always possible. ASUS' new EA-AC87 and existing RT-AC87U and RT-AC3200 fit this need.
For times when you need WiFi, 802.11ac gives the best speeds and reliability, but not every device ships with this spec so the new EA-AC87 AP can convert a Gigabit Ethernet connection from your gaming PC or even Xbox One, PS4 or NAS/HTPC (all together - there are four Ethernet ports) into 802.11ac wireless that then connects to your main 802.11ac router.
