Dual-band wireless routers which contain both 2.4 GHz and 5 GHz are now commonly usef. If your desktop or laptop supports 5GHz Wi-Fi, you are assured of faster and smoother Internet connection. However in some cases, the 5GHz Wi-Fi might not work when you upgrade to Windows 10.
In our previous post, we discussed about how to enable the 5GHz Wi-Fi on your laptop or router.
So in today's article, we will look at how to fix 5GHz wi-fi on your laptop or router if not working. But before we proceed, let's address the differences between the 2GHz and the 5GHz wi-fi.
2GHz vs 5GHz
802.11a, 802.11g & 802.11n can work on both 2.4GHz and 5GHz while 802.11ac can only work on the 5GHz. There are two major differences between 2.4GHz and 5GHz which are interference and range.
#1 The 2.4GHz is more crowded than 5GHz, and devices on 2.4GHz run into more interference than on 5GHz. The 5GHz band has 23 available channels for devices, while the 2.4 GHz has only 3 channels
