Your Internet, Your Rules: High-Speed 4G without Compromises
The ASUS 4G-AC86U is the ultimate solution for anyone who needs fast internet without a fixed-line connection. Simply insert a Nano-SIM card and you'll establish a lightning-fast connection via the 4G Network. Thanks to the modern Qualcomm Snapdragon X12 modem with 4G Cat. 12 support, theoretical speeds of up to 600 Mbit/s are possible. That's more than enough power for demanding applications like 4K video streaming, online gaming, or large downloads. In locations with a weak mobile signal, you can also connect external 4G Outdoor Antennas to significantly improve reception.
Always Online: The Intelligent Dual-WAN Failover
What happens if your primary internet connection fails? With the 4G-AC86U: absolutely nothing. It is a perfect router with mobile backup. Simply connect your cable or DSL / VDSL Routers modem to the dedicated Gigabit WAN port. The router immediately detects when the connection drops and seamlessly switches to the 4G connection via the SIM card. You can also operate the two connections in load-balancing mode to optimally distribute the available bandwidth. This flexibility makes it the ideal choice for home offices and small businesses where a stable internet connection is business-critical.
AC2600 WiFi Power for a Connected Home
A fast internet connection is of little use if the WiFi cannot keep up. The 4G-AC86U delivers impressive performance here. As an AC2600 WiFi Router, it achieves combined speeds of up to 2600 Mbit/s on the 2.4 and 5 GHz bands. Thanks to 4x4 MU-MIMO technology, it can supply multiple compatible devices simultaneously at full speed without bottlenecks. ASUS AiRadar Beamforming technology specifically focuses the WiFi signal on your end devices, ensuring a more stable connection and greater range throughout the house.
Enterprise-Level Security with AiProtection Pro
Your data and devices deserve the best protection. That's why the 4G-AC86U is equipped with AiProtection Pro, a comprehensive security package powered by Trend Micro™. This system protects your Network on multiple levels: It blocks malicious websites, prevents attacks through an Intrusion Prevention System (IPS), and isolates already infected devices before they can cause further damage. And the best part: This protection is free for life and is regularly updated to protect you from the latest threats.

Frequently Asked Questions (FAQ)
Can I use the ASUS 4G-AC86U without a landline connection?
Yes, that is its primary application. You only need a Nano-SIM card with an active data plan. The router then establishes an internet connection via the 4G/LTE mobile network.
Which SIM card size is required?
The router uses a Nano-SIM card, the smallest available SIM card size.
Is it possible to connect external 4G Antennas to improve reception?
Yes, the router has two dedicated ports for external mobile Antennas. This allows for the connection of more powerful outdoor or directional antennas to significantly improve reception in locations with weak signals.
Does the router support ASUS AiMesh?
Yes, the 4G-AC86U is AiMesh compatible. It can function as a main router in a mesh system or be added as a node to an existing ASUS AiMesh network to extend Wi-Fi coverage.
What does 4G Cat. 12 mean in practice?
4G Category 12 enables theoretical download speeds of up to 600 Mbit/s. This is achieved through technologies like Carrier Aggregation, where multiple frequency bands of the mobile provider are bundled. The actual speed achieved depends heavily on the network coverage and utilization of the mobile provider at the location.
Is the router suitable for online gaming?
Yes, thanks to the Adaptive QoS function, game traffic can be prioritized to reduce latency (ping). The stable Wi-Fi connection and Gigabit LAN ports also contribute to a good gaming experience. However, the stability of the 4G connection itself depends on the mobile network.
