The exact radio frequency that your wireless router uses to broadcast your network’s wireless signal is listed in your router’s Web Administration page. You can access the page through any browser on your computer or applicable wireless device, such as a tablet. Depending on your router model, the device may broadcast a Wi-Fi signal in the 2.4-GHz frequency band, the 5-GHz frequency band or either if it is capable of dual band broadcasting.
