Hello, friend!
If you want faster wifi, you can click the Advanced > WLAN tab, and choose 5G Basic Network Settings from the navigation tree on the left. In the right pane, configure the basic parameters of the 5G Wi-Fi network.
However, the 5 GHz Wi-Fi range is very small.
If you want more wifi coverage, you can choose to purchase an AP compatible with your device. You click the Advanced > WLAN tab, and choose WiFi Coverage from the navigation tree on the left. In the right pane, specify the SSID used for smart WiFi coverage and add the identified external AP devices to the WiFi network.
Thanks!
