Four transmit and four receive streams deliver combined wireless speeds up to 2334 Mbps: up to 1734 Mbps on the 5GHz band and 600 Mbps on 2.4GHz, plenty of headroom for 4K streaming, large file transfers, and low-latency online gaming at the same time.\u003c\/p\u003e\n\u003cp\u003eUnder the hood, a 1GHz dual-core main processor handles routing, USB, and 2.4GHz traffic while a second dedicated dual-core processor runs the 5GHz band. Hardware NAT acceleration removes the usual bottleneck between your internet connection and your home network, boosting WAN-to-LAN throughput two to five times over software-based routing.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDual-band AC2400 WiFi with combined speeds up to 2334 Mbps (600 + 1734 Mbps)\u003c\/li\u003e\n\u003cli\u003eTrue 4x4 antenna design with MU-MIMO support and AiRadar beamforming for strong, stable coverage to the far corners of your home\u003c\/li\u003e\n\u003cli\u003eAiProtection network security powered by Trend Micro, included free for the life of the router, with robust parental controls\u003c\/li\u003e\n\u003cli\u003eAdaptive QoS prioritizes gaming, streaming, and work traffic the way you choose\u003c\/li\u003e\n\u003cli\u003e1GHz dual-core processor plus a dedicated 5GHz WiFi processor, with hardware NAT acceleration\u003c\/li\u003e\n\u003cli\u003eFour Gigabit LAN ports and one Gigabit WAN port for wired devices\u003c\/li\u003e\n\u003cli\u003eUSB 3.0 and USB 2.0 ports for shared storage, printer sharing, and 3G\/4G dongle backup internet\u003c\/li\u003e\n\u003cli\u003eDual WAN failover and a built-in VPN server (OpenVPN, PPTP, L2TP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eASUSWRT Interface, App Control, and AiCloud\u003c\/h4\u003e\n\u003cp\u003eThe ASUSWRT web interface gets you online with a simple three-step setup and no discs or extra software, then opens up a deep set of advanced options when you want them.

As a wireless router, the RT-AC87U is not tied to any single internet company. It works with cable, DSL, and fiber providers alike once it is connected to a compatible modem or fiber gateway.

It creates and manages your WiFi network but must connect to a modem or fiber gateway to reach the internet.\u003c\/p\u003e\n\n\u003ch4\u003eWhat internet plans can the RT-AC87U handle?\u003c\/h4\u003e\n\u003cp\u003eThe Gigabit WAN port supports plans up to 1 Gbps for wired connections. Over WiFi, real-world device speeds make the RT-AC87U a strong fit for internet plans up to about 500 Mbps.\u003c\/p\u003e\n\n\u003ch4\u003eDoes the RT-AC87U support MU-MIMO?\u003c\/h4\u003e\n\u003cp\u003eYes. Its 4x4 Wave 2 5GHz radio supports MU-MIMO, which lets the router serve multiple compatible devices at once instead of taking turns, keeping speeds up in busy households.\u003c\/p\u003e\n\n\u003ch4\u003eIs AiProtection free?\u003c\/h4\u003e\n\u003cp\u003eYes. AiProtection is powered by Trend Micro and included for the life of the router at no charge. It blocks malicious sites, guards against network vulnerabilities, alerts you if an infected device is detected, and includes the parental controls.\u003c\/p\u003e\n\n\u003ch4\u003eCan I share a USB drive or printer on my network?\u003c\/h4\u003e\n\u003cp\u003eYes. The USB 3.0 and USB 2.0 ports support shared storage, media streaming, and printer sharing across your network, plus remote file access through AiCloud 2.0. You can also plug in a 3G\/4G USB dongle as a backup internet connection.\u003c\/p\u003e\n\n\u003ch4\u003eIs a WiFi 5 router like this still worth buying in 2026?\u003c\/h4\u003e\n\u003cp\u003eFor plans up to about 500 Mbps, the RT-AC87U remains a strong value with features that still beat many rental gateways. Just note that ASUS no longer issues regular firmware updates for this generation.
