Foreword
If Nighthawk AX4 (review link) is Netgear’s entry-level AX router, then the Nighthawk AX8 (official website link) that comes to the Koolshare review room this time is It belongs to the mid-range level among AX routers owned by Netgear. Nighthawk AX8 is carefully designed and uses advanced technologies such as OFDMA, MU-MIMO, 160MHz channel support and 1024 QAM to provide four times the data capacity of previous standards, significantly improving network efficiency. Let’s take a look at its performance

BCM4908 has 5 PHYs, responsible for LAN1-LAN5. The WAN port uses an independent PHY chip BCM54612E. The wireless part has an independent external power amplifier circuit PA and a low-noise power amplifier receiving circuit LNA, which can effectively increase the transmit power and reduce noise interference. Except for USB3.0, which is the ancestral black tape shielding method, other main chip areas are metal shielded, covered with thick heat dissipation armor, equipped with fans to assist heat dissipation, and have excellent workmanship

Summary
▲As the second AX router in the Nighthawk family, Nighthawk AX8 adopts the full Broadcom solution of BCM4908 BCM43684 BCM43684, with solid workmanship and excellent heat dissipation. The WAN port and LAN1 port support aggregation, making 1000M broadband useful. LAN4 and LAN5 also support port aggregation. When multiple clients access, you can feel the performance improvement brought by port aggregation.
Nighthawk AX8 also performs very well in terms of wireless throughput. The throughput of the 2x2 160Mhz AX200 wireless network card has exceeded the PCE-AC88, which makes me look forward to the arrival of the 4x4 160Mhz AX wireless network card. In addition, Nighthawk AX8 USB3.0 reading and writing is also very conspicuous. It seems that the tape shielding does not have a big impact on USB3.0 performance. All in all, this is a wireless AX router with unique appearance and powerful performance, worthy of choice by network enthusiasts
