This is a Linksys EA7500 Max-Stream™ AC1900 MU-MIMO Gigabit Wi-Fi Router. It is in perfect working condition, and it comes with the AC power adapter. Product details The Linksys EA7500 Max-Stream AC1900 MU-MIMO Gigabit Router ($199.99) represents the company's second foray into the Multi-User Multiple-Input, Multiple-Output (MU-MIMO) router arena. Like its predecessor, the Linksys EA8500 Max-Stream AC2600 MU-MIMO Smart Wi-Fi Router ($129.99 at Amazon)(Opens in a new window) , the EA7500($135.00 at Amazon)(Opens in a new window) can serve multiple clients simultaneously (rather than sequentially) without bandwidth degradation. However, those clients must be equipped with a network adapter that supports MU-MIMO technology in order to take advantage of the increased throughput. That said, the EA7500 is equipped with plenty of I/O ports and management settings, and it delivered speedy throughput in our 2.4GHz, 5GHz, and MU-MIMO tests. It's our top pick for midrange routers. Design and Features The EA7500 is a dual-band, 802.11ac, AC1900 router with a maximum potential bandwidth of 600Mbps on the 2.4GHz band and 1,300Mbps on the 5GHz band. It's powered by a 1.4GHz dual-core Qualcomm processor and uses three detachable antennas for 3x3 data streaming. It can operate in router, bridge, and access point (AP) modes.
