Dual-band WiFi 6 router for busy homes

The ASUS RT-AX3000S delivers AX3000 wireless speeds across 2.4 GHz and 5 GHz bands. It supports IEEE 802.11ax with 1024-QAM, OFDMA and MU-MIMO to handle many simultaneous devices. Four external antennas and four Gigabit LAN ports plus one Gigabit WAN port provide wired backhaul options. The unit runs on a 12 V 1.5 A supply with 256 MB RAM and 128 MB flash.

AX3000 total throughput decides fit

Combined wireless data rates reach 3.0 Gbps, split as 574 Mbps on 2.4 GHz and 2402 Mbps on 5 GHz. Wired throughput exceeds 1 Gbps through the Gigabit ports. If your internet plan or local traffic stays within this envelope the router will not bottleneck; higher multi-gigabit WAN or LAN needs cannot be met by this model.

Handles typical smart-home loads with headroom

The 256 MB RAM and 128 MB flash comfortably run VPN server and client modes including WireGuard, OpenVPN and Instant Guard alongside parental controls and AiMesh node duties. Very heavy concurrent VPN tunnels or hundreds of active IoT clients may exhaust memory before the radio bandwidth limit is reached.

Questions about this item

What does the AX3000 rating mean for actual throughput on this router?

The AX3000 rating combines 574 Mbps on the 2.4 GHz band and 2402 Mbps on the 5 GHz band; real-world throughput exceeds 1 Gbps.

How does the Gigabit WAN port affect the maximum internet speed I can use?

The single 10/100/1000M WAN port caps incoming internet connections at 1 Gbps, so plans faster than that will be bottlenecked at the router.

How much space do the four external antennas need when the router is placed on a shelf?

The unit measures 2.20 inches high, 9.06 inches wide and 5.28 inches deep; the external antennas add height and can be angled to fit tighter spaces.
