Asus RT-AX88U AX6000 Dual-Band Wi-Fi Router

ASUS RT-AX88U Overview

The ASUS RT-AX88U is a dual-band AX6000 WiFi 6 flagship built for smart homes packed with connected devices. Its 4x4 radios deliver up to 1148 Mbps on the 2.4GHz band and 4804 Mbps on the 5GHz band, with 160MHz channels and 1024-QAM pushing wireless performance well beyond WiFi 5 routers.

WiFi 6 combines OFDMA and MU-MIMO so the router serves many devices at once instead of taking turns, which keeps gaming, 4K streaming, and video calls smooth even on a crowded network. A 1.8GHz quad-core processor with 1GB of RAM provides the horsepower, and eight Gigabit LAN ports make this one of the best wired-connectivity routers in its class.

AiMesh, App Control, and Lifetime Security

The ASUS Router app handles setup, traffic monitoring, diagnostics, and firmware updates from your phone. If you later need more coverage, AiMesh lets you link the RT-AX88U with other compatible ASUS routers into a seamless mesh network instead of replacing it. AiProtection Pro, powered by Trend Micro, blocks internet threats for every connected device and never requires a subscription, and WPA3 support keeps your wireless security current.

What's Included

Will this work with my internet company?

Yes. The RT-AX88U is a wireless router, so it is not tied to any single internet company and works with cable, DSL, and fiber providers alike once connected to a compatible modem or fiber gateway. If you need a modem to pair with it, you can browse modems by internet provider.

If your provider issued a combined modem router gateway, connect the RT-AX88U behind it and ask your provider to enable bridge mode so the ASUS handles all WiFi duties for the best performance.

Skip the Monthly Rental Fee

Provider WiFi equipment rents for $10 to $15 per month, up to $180 per year, and rarely matches flagship performance. A professionally refurbished RT-AX88U delivers WiFi 6 speeds and lifetime security for a fraction of its original retail price, typically paying for itself within the first year of avoided fees.

Setup

1. Connect an Ethernet cable from your modem to the RT-AX88U's WAN port, then power cycle the modem.
2. Plug in the router and wait for the power light to stabilize.
3. Connect a phone or computer to the preset WiFi network printed on the label.
4. Open the ASUS Router app (or router.asus.com) and follow the quick setup wizard to name your network and set a password.
5. Reconnect your devices, and add AiMesh nodes later if you want to extend coverage.
