Contents: In 2020 Wi-Fi 6 (802.11ax) wireless routers began rolling out. See: Wi-Fi 6, explained: how fast it really is - The Verge Designation / Notation ACxxxx AC1900 = AC Standard 1900 Mbps total (600 Mbps on 2.4 GHz and 1300 on 5 GHz) To get higher than 1900 Mbps routers use 2 5Ghz radios (tri-band). See terms below for more specifications 802.11n vs 802.11ac 802.11n and 802.11ac are both dual band routers with 2.4 and 5 GHz radios. 802.11ac can support more antennas, up to 8, and has a higher bandwidth per antenna vs 802.11n. 802.11n supportes four spatial streams (4x4 MIMO) and a channel width of 40MHz 802.11ac suports eight spatial streams and has channels up to 80MHz wide See MIMO: Why Multiple Antennas Matter | Cisco Meraki Blog Does An AC Router Improve N Device Performance? - SmallNetBuilder They compared AC routers against the top-ranked ASUS RT-N66U as the reference N router. Download speed improvement: See more throughput comparisons below. See Also What is 802.11ac Wi-Fi, and how much faster than 802.11n is it? | ExtremeTech and Gigabit Wireless? Five 802.11ac Routers, Benchmarked - 802.11ac: Tom's Hardware My Tests 5 GHz vs 2.4 GHz. 2.4 GHz more penetrating power to go thru walls. More interference from other devices, cordless phones, baby monitors, etc. I got mixed results with a Netgear R6250 (AC1600) at our cabin thru a floor and 2 walls. 2.4 was faster some times and 5 GHz was faster others 5 Ghz - More bandwidth I got better throughput thru 4 walls on 5 GHz (117 Mbps) than with 2.4 GHz with the D-Link DIR-868L AC1750 supplied by Optimum (Cablevision). My cordless phone is 1.9GHz so should have not been a problem on either band. In my tests tests thru a wall I got ARRIS DG1660A 802.11n 20 Mbps Netgear R6250 (AC1600) 130 Mbps See Wireless Wi-Fi Testing
