hp pavilion 17 notebook not connecting to internet

[joeca23]

Hi,

My computer was connecting to my home wifi perfectly fine and I tried to download Kaspersky internet protection that I bought for it and now it won't connect to the internet anymore. I uninstalled Kaspersky but that didn't change anything. 

Any ideas what's wrong?

A very warm welcome to the HP community. A very good day to you. 

I understand that you have an HP Pavillion 17 series laptop with WinXP. I read that the laptop stopped connecting to the wifi after installing Kaspersky Internet Protection. However, you have uninstalled it and still the laptop does not connect to the wifi. I appreciate the steps you have performed and have certainly done a good job. Not worry, I'll do my best to help you. 

To provide an accurate resolution, I need a few more details: 

• Did you uninstall the Kaspersky from the control panel and all the entries of this software are removed?

Meanwhile, I suggest you to perform a Microsoft system restore to rollback the laptop to an earlier date when it acually was able to connect to the internet. This will not delete your data. 

If the issue persists after performing a Microsoft system restore then I suggest you to perform the steps as described in detail below to fix wireless connectivity issues;

First, we have a step by step guide to walk you through the troubleshooting process here: 
Troubleshooting Your Wireless Network and Internet Connection

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.

Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network.

If those three 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.

Hope this information helps. Let me know. All the best! 🙂
