Nowadays, dual-band wireless routers are very popular, which contain both 2.4 GHz and 5 GHz. If your desktop or laptop also supports 5GHz Wi-Fi, you could get a faster and smoother Internet connection. After upgrading to Windows 10, your 5GHz Wi-Fi doesn't work or disappear. Don't tear your hair out. Here's how to fix the 5GHz Wi-Fi not showing up or not working issue if your PC supports 5GHz.
1. The 2.4GHz is way 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.
2. The 2.4GHz has a further range compared with 5.0GHz band, and goes through walls better. The 5GHz is limited to indoor use only.
