my device cannot connect to wifi, all other devices including tvs can

Question

running windows 10 on hp dsektop computer, cannot connect to wifi, all other devices can.

Answer 1

If you can, you can try switching to another waveband of WIFI, they are usually 2.4 GHz (old), 4GHz (standard, if it doesn't specify, it's most likely this), and 5GHz (relatively new, bad connection with older devices). Some routers have more than one waveband listed as separate connections, but they have the same password. Another problem I had with a different device is the WPN type on the router. There's WPN2 and WPN3, along with their subsets and hybrids. WPN2 is the older standard, so if you have a router even a few years old, it probably has this. WPN3 is a different newer type of connection which older devices cannot connect to, and you will probably need a whole different router altogether.

Answer 2

Hi! Let me help you.

Please hover your mouse over the Network or Wireless icon at the lower right-hand corner, then right-click it and click Troubleshoot Network. Let the troubleshooter finish its task, then this should either resolve the problem or display an error message.

If that doesn't work, we need to remove the WIFI driver from the Device Manager and restart the pc to reinstall it.

Here are the steps to completely remove a Device from your computer.

Step 1. Use shortcut keys Windows key+ + X

Step 2. Select Device Manager.

Step 3. Expand the entry for Network Adapters, Right-click the problematic device, which is either an Intel Wireless or Realtek WIFI adapter, and select Uninstall device.

Step 4. You need to check the option Delete the driver software for this device and then click the Uninstall button.

Step 5. Reboot the computer.

After the reboot, please see if the problem is fixed.

If that still does not work, please visit the support website of your laptop or desktop and then download and install the latest Wireless driver, and then restart the PC.

Follow these steps on the Windows 10 HP desktop to troubleshoot Wi‑Fi when other devices work:

1. Check Wi‑Fi status and Airplane mode
   • Select the Network, Sound, or Battery icon on the right side of the taskbar.
   • Make sure Wi‑Fi is turned on and that a known network is selected and shows Connected. If not, select the correct Wi‑Fi and try to connect.
   • Open Start > Settings > Network & Internet > Airplane mode and ensure Airplane mode is turned off.
2. Run the Network troubleshooter
   • Go to Start > Settings > Network & Internet.
   • Select Status on the left.
   • Scroll down and select Network troubleshooter.
   • In the Troubleshoot Problems window, follow the on‑screen instructions and apply any fixes it suggests.
3. Forget and reconnect to the Wi‑Fi network
   • Open Settings > Network & internet > Wi‑Fi.
   • Select Manage known networks.
   • Select the problematic Wi‑Fi network and choose Forget.
   • Reconnect by selecting the same network from the Wi‑Fi list and entering the password again.
4. Restart modem and router
   • Unplug the router’s power cable.
   • Unplug the modem’s power cable (and remove its battery if lights stay on).
   • Wait at least 30 seconds.
   • Reinsert the modem battery (if removed) and plug the modem back in; wait until its lights stabilize.
   • Plug the router back in and wait a few minutes until it fully powers on.
   • Try connecting from the HP desktop again.
5. Try the other Wi‑Fi band (2.4 GHz vs 5 GHz)
   • If the router broadcasts both 2.4 GHz and 5 GHz networks (they appear as separate network names), try connecting the desktop to the other band and see if it connects successfully.
6. Test with another device on the same network
   • On another laptop or phone, connect to the same Wi‑Fi network.
   • If other devices connect but the HP desktop still cannot, the issue is likely with the desktop’s Windows or Wi‑Fi adapter configuration, so the steps above (troubleshooter, forget/reconnect, restart router, switch band) are the primary fixes.

If the problem persists after these steps, continue with advanced commands:

7. Reset TCP/IP and renew IP/DNS from Command Prompt
   • Select Search on the taskbar, type command prompt.
   • Right‑click Command Prompt and choose Run as administrator > Yes.
   • Run these commands in order, pressing Enter after each:
     • netsh winsock reset
     • netsh int ip reset
     • ipconfig /release
     • ipconfig /renew
     • ipconfig /flushdns
   • Restart the PC and try connecting to Wi‑Fi again.

If the desktop connects to Wi‑Fi but shows No Internet, also:

8. Renew IP and flush DNS
   • Open Command Prompt as Administrator.
   • Run:
     • ipconfig /release
     • ipconfig /renew
     • ipconfig /flushdns
9. Check proxy settings
   • Go to Settings > Network & Internet > Proxy.
   • Turn off any manual proxy settings.
10. Check IP address

• Find the IP address (see Find your IP address).
• If it looks like 169.254.x.x, the PC is not getting an IP from the router. Ensure DHCP is enabled on the router per its documentation.
