Understanding Wi-Fi technology and device performance

Overview of device impact on Wi-Fi performance
The maximum Wi-Fi speed and connection efficiency of a home network depend directly on the Wi-Fi standards supported by connected devices (smartphones, laptops, gaming consoles, and smart TVs). While high-speed fiber internet delivers multi-gigabit data to the home router, individual devices can only transmit and receive data up to the limits of their internal Wi-Fi hardware.
Definition of a Wi-Fi standard
A Wi-Fi standard is a technical protocol defined by the Institute of Electrical and Electronics Engineers (IEEE) that dictates how wireless devices transmit data over radio frequencies. Each successive IEEE standard increases maximum bandwidth, reduces latency, and improves multi-device efficiency:
- Wi-Fi 5 (802.11ac): Supports basic high-speed wireless networking on older client hardware.
- Wi-Fi 6 (802.11ax): Increases efficiency and device capacity on 2.4 GHz and 5 GHz frequency bands.
- Wi-Fi 6E (802.11ax extended): Introduces access to the 6 GHz frequency band for lower network congestion and faster speeds.
- Wi-Fi 7 (802.11be): Delivers next-generation wireless throughput, higher channel bandwidth, and ultra-low latency.
To utilize maximum internet speeds and eliminate lag (the response time between your device and the network), router hardware must support the same or higher Wi-Fi standards as the connected devices:
- Backward Compatibility: Modern routers support legacy devices, but older hardware operating on legacy standards (like Wi-Fi 5) cannot achieve Wi-Fi 6 or Wi-Fi 7 speeds.
- Hardware Matching: Connecting a Wi-Fi 6 or Wi-Fi 7 smartphone to a matching Wi-Fi 6/7 router unlocks the highest available throughput and lowest network latency.
- Network Optimization: Upgrading home routers ensures that new hardware operates at peak capability without bottlenecks.
Wi-Fi speeds depend on the technology your devices are able to support. To make things easier, we’ve put together a list of common phones, laptops and gaming consoles along with their Wi-Fi capabilities. Use this chart to check which Wi-Fi technology your devices are built with so you can make the most out of them. Check out the comprehensive list here.
