| Wireless network speed is lower than wired network speed |
This is likely due to the signal attenuation caused by interference to the Wi-Fi signal. Wi-Fi signals are transmitted over the air. Therefore, the number of antennas, signal interference, transmission distance, obstacles, and number of wireless devices can all cause signal attenuation, which affects the tested Wi-Fi rate. Generally speaking, the tested Wi-Fi rate is lower than the tested wired network rate.

Note:
- If the tested rate of a Wi-Fi 7 device is the same as that of a Wi-Fi 6 device when each is connected to a Wi-Fi 7 router, you are advised to enable MLO. (Log in to the router's web-based management page, click My Wi-Fi, enable MLO, and click Save.)
- iPhone X and earlier versions are Wi-Fi 5 devices, and iPhone 11 and later versions are Wi-Fi 6 devices.
The preceding data was obtained in a minimal interference environment. During actual usage, if the interference is greater, the tested speed may be lower. The greater the interference, the greater the difference will be.
1. When a user tests the speed on a mobile phone, the results may vary from phone to phone. The speed tested on a single-antenna mobile phone is always lower than that on a dual-antenna phone. The greater the interference, the greater the difference will be.
2. When the user tests the speed on the computer, the model of the wireless network adapter may affect the test results as well. The speed tested on a device with a 1 x 1 wireless network adapter is always lower than that on a device with a 2 x 2 wireless network adapter.
3. The tested rate is limited by the uplink bandwidth. For example, if the uplink bandwidth is 20 Mbps, the tested maximum rate can only reach 20 Mbps. In addition, if the WAN port is a 100 Mbps network port, the maximum speed test results can only approach 100 Mbps, even if the bandwidth is 200 Mbps.
