Telecom routers have two WiFi signals, mainly because the router supports dual band functionality, which means it operates on two frequency bands simultaneously: 2, 4GHz, and 5GHz. These two frequency bands each have their own characteristics and advantages, suitable for different usage scenarios. 1、 2. 4GHz frequency band
Features: Relatively slow speed, but strong ability to pass through and wrap around walls, with a wide coverage area.
Applicable scenarios: When the user is far away from the router or obstructed by walls or other obstacles, choosing WiFi signals in the 2 and 4GHz frequency bands can maintain good connection quality. When covering a large area or penetrating multiple walls, the 2 and 4GHz frequency bands are better choices. 2、 5GHz frequency band
Characteristics: The speed is much faster than the 2 and 4GHz frequency bands, but the coverage and penetration capabilities are poor.
Applicable scenario: When the user is in the same room as the router and there are not many obstacles, choosing a 5GHz WiFi signal can achieve faster network speed. Suitable for scenarios that require high-speed data transmission, such as online gaming, high-definition video streaming, etc. 3、 Settings and Selection
Setting method: Users can set and select the frequency band to use through the router's management interface (usually accessed through a browser to specific IP addresses such as 192, 168, 1, 1). In wireless settings, you can choose to enable two frequency bands simultaneously or only one frequency band as needed.
Suggestion for selection: Choose the appropriate frequency band based on your actual needs and usage scenarios. If you need faster speed and are closer to the router, you can choose the 5GHz frequency band; If you need stronger wall penetration capability or larger coverage area, you can choose the 2 and 4GHz frequency bands. 4、 Precautions
Frequency interference: Due to its widespread use, the 4GHz frequency band may be affected by interference from other electronic products such as microwave ovens and Bluetooth devices, resulting in unstable signals. The 5GHz frequency band has relatively less interference.
Router performance: As the price of a router increases, its performance will also improve accordingly, including an increase in the speed difference between the two frequency bands.
Compatibility: Ensure that the device supports the selected frequency band. Although most modern devices support dual band functionality, there are still some older devices that may only support the 2 and 4GHz frequency bands.
The appearance of two WiFi signals on telecom routers is to meet the needs of users in different scenarios. Users can choose the appropriate frequency band according to their actual situation to obtain the best network experience.
