Overview
ASUS builds this router on the newer Wi-Fi standard with retractable antennas, wired gigabit ports and a USB port. Network security is listed as subscription-free, and the router joins an AiMesh network and includes a built-in VPN.
The reason to buy is a feature set that includes parental control and security without a monthly fee, plus antennas you can aim. The limit is the vague coverage claim and the lack of a stated multi-gig port. The disclaimer notes that real speed varies with building materials.
Who it's for
Apartments and mid-size homes with streaming and gaming on several devices are the setting. Large houses, or users with very fast internet, may need mesh nodes or faster ports.
Pros and cons
- Retractable antennas can be adjusted
- Security and parental control without a subscription
- USB port included
- Coverage area not quantified
- Gigabit-only wired speeds
- Enterprise-style security entries only
Performance notes
The router uses two radio streams per band with wide channels and denser modulation to move more data per second, which helps crowded networks. Antenna angle changes where the signal is strongest. Actual throughput varies with traffic, walls and the internet plan, as the seller's disclaimer notes.
