What is 2.4Ghz
2.4 GHz refers to a gigahertz, which is a unit of frequency representing one billion cycles per second. In the context of Wi-Fi, 2.4 GHz is one of two primary radio frequencies used by wireless networks, characterized by its longer range, better ability to penetrate walls, and broader compatibility with devices, though it also experiences more interference and slower speeds due to higher congestion.
What is 5Ghz
5GHz refers to a higher frequency for Wi-Fi, which enables faster data speeds but offers a shorter range and less signal penetration through walls compared to the older 2.4GHz band.
Why would I need to do this?
Switching your devices to use the 5GHz Wi-Fi band automatically means your laptop, phone, or tablet will always connect to the faster signal instead of defaulting to the 2.4GHz band. The 5GHz band allows data to move more quickly and with less interference. This results in smoother video calls, more reliable streaming during presentations, and fewer disruptions when using cloud applications or large file transfers.
Adjust Settings on Your Device
Please keep in mind that, as we do not provide the device you are using, we only have general steps below. For more specific advice based on your device, please speak to your IT Team or check the user guide/manual.

Click OK to the save.
Mac (Apple Computer)
Click the Apple menu in the top-left corner of your screen.
Select System Preferences (or System Settings on newer macOS).
Click Network.
Choose Wi-Fi from the left-hand menu.
Click Advanced… (or Details on newer macOS).
Find the option for Preferred Networks or Wi-Fi Options.
Change the Wi-Fi band setting (if available) to 5GHz or Prefer 5GHz.
On some versions of macOS, you’ll see a setting under Hardware > Configure where you can select the band or channel.
Click OK, then Apply to save.
Phone or Tablet
(Steps may vary by brand and version)
Open the Settings app.
Tap Connections (or “Network & Internet”).
Tap Wi-Fi, then tap the gear/cog icon next to your connected network.
Look for Wi-Fi Frequency Band or Advanced Settings.
Select 5GHz only (or “Prefer 5GHz”).
Your phone will now stay on 5GHz whenever it’s available.
Troubleshooting: If 5GHz Doesn’t Work or Doesn’t Show Up
If your device keeps connecting to 2.4GHz, or you don’t see a 5GHz option, try these fixes:
Check if your device supports 5GHz
Older devices may only work on 2.4GHz.
Search your device model online with “supports 5GHz Wi-Fi” to confirm.
Update your device software/drivers
On Windows: Update your Wi-Fi adapter driver (please first check with your IT Team, that they are happy for this to go ahead on your device).
On Mac, iOS, or Android: Install the latest system update.
Move closer to your router
5GHz is faster but has a shorter range than 2.4GHz.
If you’re far away or behind thick walls, your device may switch back to 2.4GHz.
