Hi@pzoli,
When a Wi-Fi 5 device is connected to a Wi-Fi 6 router, the speed of the Wi-Fi 5 device is mainly limited by the device's own Wi-Fi 5 technology, and the speed of Wi-Fi 5 will not be directly increased to Wi-Fi 6 by connecting to a Wi-Fi 6 router.
When you use an Ethernet cable to test the router's LAN port, which is the wired speed, it is 900–950 Mbps, which is a relatively ideal speed. Because the Ethernet ports of Archer AX23 are 1× Gigabit WAN Port+4× Gigabit LAN Ports. So the ideal wired speed is also close to 1Gbps.
Generally speaking, the wireless network speed of the router is lower than the wired network speed of the router. First, the wireless network of the router is achieved by converting the wired network signal into a wireless signal.
The wireless signal speed is usually lower than the wired speed for the following reasons:
1. Transmission medium: Wired networks use physical cables to provide more stable and faster connections, while wireless signals are transmitted through the air and are limited by signal strength and interference.
2. Bandwidth sharing: Wireless networks need to share bandwidth between multiple devices. The more devices connected, the slower the speed may be.
3. Signal attenuation: With the increase of distance and the presence of obstacles, the wireless signal will attenuate, resulting in a decrease in speed.
4. Interference factors: Other wireless devices, electronic products and building structures will interfere with wireless signals.
5. Technical limitations: Although modern wireless technologies (such as Wi-Fi 6) have significantly improved speeds, it is still difficult to reach the level of wired connections.
In general, the WiFi speed of Archer AX23 is 5 GHz: 1201 Mbps (802.11ax), 2.4 GHz: 574 Mbps (802.11ax), which mainly refers to the Wi-Fi technology used by these two Wi-Fi bands and the highest negotiated speed under ideal conditions, rather than the actual speed of the router.
