We’re going to divide it into several sections so that you can find what you need quickly without going through the whole article.

1. If No Device is Working

That usually means there’s something wrong with your router or your internet service provider (ISP). More often than not, simply restarting the router fixes it. if it doesn’t, contact your ISP and inquire if their service is down. Alternatively, you can enter your router IP address in the browser to get into the admin panel and use the reset option from there.

2. The Device is Working on 2.4 GHz but not on 5 GHz

(A) Use Command: If the laptop or computer is working on another network, no need to reset your router or the access point. Also, it’s safe the assume that the drivers are working just fine, so no need to update that either. Follow these steps, one by one until your internet is fixed.

Flush your DNS (Domain Name System)
Bring up the Run dialogue box by pressing Windows + R key
Type ipconfig/flushdns and hit enter
This should remove all previous DNS cache from your system and force your computer into requesting a new DNS address from the server.

Now check your internet connection again.

Use the netsh command to get a new IP address.

Press Windows + X key
Select Windows PowerShell (Admin)
Type the command netsh int ip reset
Restart your computer

If it still doesn’t work, use the following command –

netsh winsock reset catalog

netsh int ipv4 reset reset.log

and restart

(B) Update your network adapter:

Another tried and tested method is simply updating the outdated driver.

Go to Device Manager
Select Network Adapter and find your Wireless Network Adapter
Select Update Driver by right-clicking on it. Let Windows take care of the rest.

(C) Disable the Fast Startup option in Windows:

Sometimes the fast startup option gets in the way of Windows properly loading or renewing settings or data.

Pressing the Windows + X key, select Power Options
Select Additional Power Settings from the right
On the left, look for What the Power Buttons Do, click on it
Then click on Change Settings that are Currently Unavailable
Untick the Fast Startup checkbox, and restart.

(D) Fiddle with the wireless network standard (turn off 5 GHz and on again):

Go to Network Connection by right-clicking on the Start menu
Double-click on the Wi-Fi Adapter and open the Network Adapter
Select Configure and go to the Advanced tab
Select 802.11n/ac and turn it off, press Ok
Next, go to the same menu and turn it back on.
