As WiFi 6 becomes more widespread, we can expect to see even more devices connecting to 5GHz WiFi networks.
Conclusion
The number of devices that can connect to 5GHz WiFi depends on various factors, including network congestion, AP capacity, and channel bandwidth. While the theoretical limit is 255 devices per AP, the practical limit is much lower, ranging from 20-30 devices for home networks to 10-20 devices for enterprise networks. By optimizing your 5GHz WiFi network using techniques like channel bonding, QoS, and WiFi analytics tools, you can support a larger number of devices. As WiFi 6 becomes more prevalent, we can expect to see even more devices connecting to 5GHz WiFi networks.
