Radio frequency is the range of electromagnetic waves that are used to transmit wireless signals.
Different devices and networks use different radio frequencies, such as 2.4 GHz or 5 GHz, to communicate with each other. If there are multiple devices or networks using the same or overlapping radio frequencies, they can interfere with each other and cause Wi-Fi connection issues, such as intermittent disconnections, slow speeds, or poor quality . To fix this issue, the technician can try changing the radio frequency or channel of the router or the laptop, to avoid interference from other sources. The technician can also use a tool such as Wi-Fi Analyzer to scan the nearby wireless networks and find the best frequency or channel to use. Alternatively, the technician can move the router or the laptop to a different location, away from potential sources of interference, such as cordless phones, microwaves, Bluetooth devices, or other routers.
