2.4 GHz vs. 5 GHz Wi-Fi: What's the Difference?

Choose between longer-range and higher-performance Wi-Fi bands when a router exposes separate networks.

Quick Answer

2.4 GHz usually reaches farther and penetrates obstacles better; 5 GHz often provides higher performance at shorter range.

Step by Step

  1. Determine whether the problem affects one device or every device on the network.
  2. 2.4 GHz usually reaches farther and penetrates obstacles better; 5 GHz often provides higher performance at shorter range.
  3. Change one setting or component at a time and test again.
  4. Record existing router/network settings before changing passwords, DNS, addressing, or advanced configuration.

If That Doesn't Work

  • Router menus, indicator lights, and terminology vary by manufacturer and internet provider.
  • Avoid factory-resetting a modem/router unless you know how it is provisioned and have the information needed to restore the connection.
