Get Better Wireless by Preferring 5 GHz Band

If your laptop is experiencing slow WiFi, it might be stuck on the 2.4 GHz Band. The 5GHz band will provide a faster WiFi service. See below for instructions on how to prefer the 5GHz band based on your specific operating system.

Windows Devices

You can check to see which band your device is using by following these steps:

  1. Click on the start menu and type in Wifi Settings and press Enter
  2. Click on the link that says Hardware Properties
  3. Look for the Network band as shown below: 

If it shows 2.4 GHz as the band, then it likely means you may have more wireless issues than if it is on the 5GHz band. Follow these steps to fix this issue by preferring the 5GHz band:

  1. Click on the start menu and type in Device Manager, then press Enter
  2. Locate your WiFi adapter under Network Adapters and double click it. (Make sure it is the one that says Wireless Adapter)
    1. If you do not see an Advanced tab, you may need to click on the Change Settings button. 
  3. In the Advanced tab of the adapter properties window, click on Preferred Band and set the Value dropdown to Prefer 5GHz Band.  This will allow automatic band-steering to 5 GHz and ensure a faster WiFi experience.
  4. Click OK and then your wireless will disconnect and reconnect

See the following image for what it should look like: 

Mac OS Devices

macOS always defaults to the 5 GHz band over the 2.4 GHz band. This happens as long as the RSSI for a 5 GHz network is -68 dBm or better (NOTE: Better equates to a smaller number).

To learn the RSSI for the associated network, hold the Option key while you click the Wi-Fi  menu.
