Wifi ADAPTER NOT SEEN IN NETWORK CONNECTIONS

Product Name: HP Pavilion 15 Notebook PC
Operating System: Microsoft Windows 8.1 (64-bit)

the wifi adapter appears sometimes and sometimes it doesn't appear, i can't use wifi whenever i want. so i am confined to use ethernet only and this confines me to leave my laptop at home only.

it is causing a serious issues, not only this many other problems are also being noticed:

1. the hp logo stucks when i start my laptop and remains like that only until i use the power button to switch it again

2. wifi adapter not available always

3. numpad is always locked when i start my system

Re: Wifi ADAPTER NOT SEEN IN NETWORK CONNECTIONS

Hi @sri49,

 

Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I came across your post and wanted to assist you. I see from the post that you are having multiple issues on your PC. Don't worry as I have a few suggestions which should help you resolve this concern,

 

Let's attempt one issue at a time. Let's start off by performing a Hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, the keyboard stops responding, or other external devices locking up.

 

To provide you with an accurate solution, I'll need a few more details:

Did this happen after a recent update/upgrade?

Have you tried to perform a Hard reset on the PC?

Have you tried to run any diagnostics?

 

In the meantime, let's start off by performing a Hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, the keyboard stops responding, or other external devices locking up.

 

Next thing, I would suggest here is to perform a Bios defaults, 

 

If the issue persists then please shut down the laptop.

Power on the laptop and immediately hit the F10 key repeatedly for the BIOS to load. 

AT the BIOS screen, press the F10 key to load the BIOS defaults. Save and exit the changes.

 

If the issue persists, I would suggest here is to turn off the PC and then try to attempt to run an extensive system diagnostics test from F2 (Please capture the failure ID for further assistance).

 

Regarding the Numpad, I would suggest you try to uninstall and reinstall the keyboard drivers from Device manager.

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:

Power cycle 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 networki...

 

I hope this helps. Let me know if you need any further assistance. I'll be more than happy to help.
