How to Change From 2.4ghz to 5ghz Wireless Network Adapter in Windows 10/8/7 [Tutorial]

Wireless adapters can run in 2.4 GHz or 5 GHz, which also refers to as bands in Windows. If you’re experiencing problems with your wireless connection, you could try and specify the preferred band.

Wi-Fi can run on two different bands of radio frequency: 5 GHz and 2.4 GHz.

With Microsoft’s recent firmware update for the Surface Pro 3, among the new bits and pieces was a new Marvell Wifi driver that lets you switch between 2.4GHz and 5GHz bands on the fly. For those of us using a dual-band router, the updated driver should help resolve any related issues.

Channels are a series of sub-bands that operate within the 2.4- or 5-GHz bands. The 2.4-GHz band worked really well when the number of devices operating on the band were few and far between, but with today’s connected world, this band has become crowded, degrading network performance.

The 5-GHz band is much less crowded, resulting in less interference and higher data throughput speeds. If all your devices support it, you can force your router to use only the 5-GHz band. To check your devices for 5-GHz band support, you can check your manual. Or you can change the setting via the steps below on your router and check for devices that no longer work. If all of them work after your router reboots, all of your devices are compatible. The higher frequency band has a smaller range, however, so you’ll want to be sure all your devices will be in range of the router, or you can invest in an extender.

In an environment with other radiating devices nearby (such as microwave ovens, cordless telephones, access points, or client devices), in order to reduce interference, you may prefer the 5GHz band over the 2.4GHz band, or the reverse.

This tutorial will apply for computers, laptops, desktops,and tablets running the Windows 10, Windows 8/8.1, Windows 7 operating systems.Works for all major computer manufactures (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung).
