What is a key factor that affects the speed of a Wi-Fi connection?

Air temperature
Protocol version
Point-to-point access
The device's operating system

The correct answer is: Protocol version

The speed of a Wi-Fi connection is significantly influenced by the protocol version being used. Wi-Fi operates under different standards, such as 802.11n, 802.11ac, and 802.11ax, each of which has specific capabilities regarding data transmission rates, frequency bands, and overall performance characteristics. For instance, newer protocols like 802.11ac and 802.11ax (also known as Wi-Fi 5 and Wi-Fi 6, respectively) offer higher data rates, improved efficiency, and better performance in environments with multiple connected devices compared to older standards. This means that as technology advances and new protocols are adopted, the potential for faster and more reliable Wi-Fi connections increases. Other factors may influence Wi-Fi performance, such as environmental elements, distance from the router, and hardware capabilities, but the protocol version directly correlates with the inherent capabilities for speed and efficiency within the Wi-Fi protocol specifications.
