In my HP Notebook 15 ac101tu, suddenly, there is no Wi-Fi. I have no option for Wi-Fi in the taskbar and in settings. The error is "Network cable not found" or "Network module is not installed"?

Welcome to HP forums, I see that you are getting wireless connectivity issues.

• Did you do any changes in the notebook?
• When did this issue start?

Meanwhile:

Try the steps mentioned in this HP troubleshooter:- Click here

A second option, is to try these steps:
Powercycle the network:
1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in the modem, and wait for it to come back online.
6. Plug in the router, and wait for it to come back online.
7. Turn on your notebook, and test your connection.

Disable the Power Off option for the adapter:
1. Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
2. Expand the Network adapters.
3. Right click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the check mark beside Allow the computer to turn off this device to save power.
6. Click OK.
7. Test.

Reset the TCP/IP settings on your PC:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.

It may also help to reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.

Reinstall the network adapter drivers:
1. Download the drivers from here but do not run them yet.
2. Go to your start screen/menu and type Device Manager.
3. Expand Network adapters.
4. Right click on the wireless adapter and choose Uninstall.
5. Run the downloaded drivers from step 1.
6. Restart your PC and test.

Test an ethernet connection:
Self explanatory. Test if the issue persists on a wired connection to rule out the wireless adapter hardware so troubleshooting can be directed towards the right areas.

Let me know if that helps.
