5. Use Another Frequency

The modern router uses dual-band technology. This means you can use any frequency between 2.4GHz and 5GHz. 5GHz band is faster but some PCs can’t adopt this and block the signal flow. You can switch the band to any frequency between 2.4 and 5 and check if the WiFi is working or not. 

Also, there are several WiFi channels, you can switch among them. 1,6, and 11 are the best channels to switch.

Here is the instruction to switch the band:

• Go to the control panel and select Network and Internet.

• Now, go to Network and Sharing Center.

• After that, right-click on Wi-Fi and go to its properties.

After doing everything from the steps above, restart your PC. If you found the problem is remaining, then follow the next method.
