Hp Laptop won't connect to internet despite wifi working

[Alex_ph]

My laptop keeps showing it's connected to the wifi but no internet. But even when it gets connected to the internet, it only lasts for a few seconds, and it won't go to certain websites and it would show, "this site is unreachable." I know the internet and wifi is working because all my other devices are connected to the internet and it's working. When I try to use usb tethering or hotspot with my phone, it would still show connected but no internet. When I use the Windows troubleshooting for network it shows I'm connected.

@Alex_ph, welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Here is a list of steps that commonly resolve issues with wireless connectivity.

First, we have a step-by-step guide to walk you through the troubleshooting process here:

Troubleshooting Your Wireless Network and Internet Connection

Second option, is to try these steps:

Power cycle the network:

• Shut down your notebook.
• Unplug the power to your router.
• Unplug the power to your modem.
• Wait at least 45 seconds.
• Plug in the modem and wait for it to come back online.
• Plug in the router and wait for it to come back online.
• Turn on your notebook and test your connection.

Disable the Power Off option for the adapter:

• Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
• Expand the Network adapters.
• Right click on the Ethernet/Wireless Adapter and click Properties.
• Click the Power Management tab.
• Remove the check mark beside Allow the computer to turn off this device to save power.
• Click OK.
• Test.

Reset the TCP/IP settings:

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

Reset the winsock catalogue:

• Go to your start screen/menu and type CMD.
• Right click on the command prompt icon and chose Run as administrator.
• In the window that opens type "netsh winsock reset" without quotes, and press enter.
• Restart your PC and test.

Reinstall the network adapter drivers:

• Download the drivers from here (select the OS and its version) but do not run them yet.
• Go to your start screen/menu and type Device Manager.
• Expand Network adapters.
• Right click on the wireless adapter and choose Uninstall.
• Run the downloaded drivers from step 1.
• 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.

If these steps do not resolve the issue, try this document published by Microsoft for networking issues: Wired and wireless network problems. You can change the operating system with the dropdown in the upper-right corner of the document.

I hope these steps help resolve the issue
