The 5 GHz band offers faster speeds compared to 2.4 GHz. It can provide more stable connections for high-bandwidth activities such as HD video streaming, online gaming, and large file transfers. Since it has more available channels, it also experiences less interference from other household devices.
However, the 5 GHz band has a shorter range compared to 2.4 GHz, and its signals are less able to pass through obstacles like walls and floors. This means you may need a Wi-Fi extender or multiple access points if you want to cover a larger area.
