What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.7 for now.

Third-party reviews

What customers like about Zyxel NBG5615

  • Supports dual-band Wi-Fi for more flexible and stable wireless connections
  • Includes two USB 2.0 ports for basic media sharing and peripheral connectivity
  • Offers useful security features such as SPI firewall, DoS protection, and IPsec passthrough
  • Provides extra features like QoS, parental controls, DLNA support, and a simplified setup mode
  • Compact and lightweight design that is easy to place in tight spaces
  • Gigabit LAN ports help wired devices avoid the bottlenecks of older Fast Ethernet routers

What customers don't like about Zyxel NBG5615

  • Uses an outdated Wi-Fi generation with much lower speeds than modern Wi-Fi 5 or Wi-Fi 6 routers
  • 5 GHz coverage is limited compared with newer and stronger dual-band models
  • The web interface and firmware are sometimes criticized as clumsy or less polished than the hardware
  • No support for newer wireless standards, so long-term future-proofing is weak
  • Some users raise concerns about support responsiveness and the security of exposed administrative interfaces

Verdict

The Zyxel NBG5615 is a simultaneous dual-band Wireless N750 media router that delivers combined speeds of up to 750 Mbps, utilizing 300 Mbps on the 2.4 GHz band and 450 Mbps on the interference-free 5 GHz band. Key characteristics include three external antennas, four Gigabit Ethernet LAN ports, and two NetUSB ports for sharing printers or storage across the network. Its main pros are the high-speed wired connectivity, hardware-accelerated NAT for improved internet performance, and DLNA certification for easy media streaming. However, it lacks support for the faster Wi-Fi 5 (802.11ac) or Wi-Fi 6 standards, and some users have reported an unpolished web interface and limited technical support.
