WiFi/Networks disappear after certain duration

[SumitB06]

My problem started about 2-3 months back. After certain duration of usage, the wifi connectivity disconnects/disappears from laptop completely. There would be no LAN or WiFi option available in network section. After reboot, it will be there as normally would(rarely requires another reboot to work). If WiFi disconnects automatically, for next couple of seconds, there will be no available options shown (do note it's not the problem with WiFi modem, as other devices are running fine at that time). After that connections will appear and I will be able to connect normally. If WiFi option disappears, then there is no connectivity option, WiFi or LAN. And at that same time, certain open windows will crash, like Chrome, task manager or any folder that is open. After reboot all these issues will be gone, but then after some time the same will happen again. The time before this happens usually varies from 10-15 minutes to 2-3 hours even, but this will happen. Troubleshooting does not pick up any issues.

My laptop came with original Windows 8.1, which updated to Windows 10 long ago. Since I am not able to backup the Windows as well due to some other issue, I am unable to go for the format option. So please suggest any other solutions, that may work.

Welcome to the HP Forums,

We'll be with you until it's all sorted.

I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Have you noticed if the network connection fails when the notebook is switched to battery power (Disconnecting the adapter)?

(If yes, Click here to troubleshoot the same)

If the issue persists or occurs at random moments, I recommend you Update the BIOS & the chipset drivers using the HP website:
Click here to download

If the issue persists, try the below steps:

1. Open DEVICE MANAGER  

2. Open up NETWORK ADAPTERS  

3. Right click on the WiFi Adapter for the pc and left click on PROPERTIES  

4. Click on POWER MANAGEMENT at the top.  

5. Remove the check mark beside: ALLOW THE COMPUTER TO TURN OFF THIS DEVICE TO SAVE POWER  

6. Click OK  

7. Close DEVICE MANAGER and test.    

NOTE:  It may also be checked under the FAMILY CONTROLLER (eg. Realtek PCIe GBE Family Controller which would be listed under the WiFi Card). If so, you could remove the check mark beside ALLOW THE COMPUTER TO TURN OFF THIS DEVICE TO SAVE POWER.

Also, did you install Windows 10 using the recovery manager or was it a retail copy from the store?

Keep me posted, as I (Or a trusted colleague) shall follow-up on this case to ensure the concern has been addressed, 

And your device is up and running again, only in case you don't get back to us, first! 

That said, If the information I've provided was helpful, give us some reinforcement by clicking the solution and kudos buttons, 

That'll help us, and others see that we've got the answers!

Good Luck.

Thank you for your reply. According to your instructions, here is the current update/information you requested.

I have somewhat customized power plan to handle battery/plugged in mode. I do use my notebook in both modes randomly, and this issue occurs irrespective of whether I am on battery or plugged in.

This issue is random in terms of duration of occurance, but it does happen sooner or later. Sometimes laptop will run for hours without any issues and then this issue comes, sometimes right of the bat, on reboot or within 30 minutes of usage. I have previously updated BIOS from HP website, which didn't fix this. I have not updated Chipset drivers, as I am not sure if they are upgraded versions that the ones already In. Since the release dates of chipset drivers go back to Nov, 2014, where I bought the device on May/June 2015.

I have made changes in Device Manager as per the steps you mentioned. Let's hope this does the trick.

Update: Issue still persists. Taken a screenshot of network panel if it helps anything.

About Windows 10, my laptop came with preinstalled 8.1, and I updated it to windows 10 during microsoft allowing free upgrade to windows 10 from windows 8/8.1

Thank you for replying with this detailed response,

I appreciate your time and efforts,

That said, I have a few more steps to help you out depending on the details you've mentioned so far,

For my next trick, I'll need you to ensure your laptop is 'not' connected to the modem/router via an Ethernet cable and then, follow the steps:

1. Go to "Control Panel".
2. Next go to "Network and Internet" and then "Network and Sharing".
3. Now click on "Manage Wireless Networks".
4. On this screen, remove all wireless connections by "right clicking" on it and select "Remove network" from the drop-down menu. 
5. After doing this, close the open windows and reboot the computer.
6. Once the computer is fully reloaded, scan for the "Wi-Fi networks". 
7. Click on the available network that you want to access and select "connect". 
8. It takes a moment, but then you will be asked to give a password for your Wi-Fi connection. Type in the password and click the "connect" button. 

It should now be connected.

NOTE: If this doesn't work, you may want to reset your modem/router, and then once it is fully loaded again, repeat the above steps.

If this doesn't work, test seeing if your laptop will connect via Ethernet. If so, then your WiFi card may be going. You can either look to replace it/have it replaced, or get an external (plugs in via USB) WiFi card.

Refer to my private message for details on getting a replacement card from HP:

Thanks for your time. According to your mentioned steps, I could not find the exact options to go to. So what I did was wait till the issue occurred. Once that happened, I went to network troubleshooter and chose to troubleshoot WiFi. It detected some issue and suggested network configuration reset and reboot, which I did. Let's see if this does solve it or not. If not, then accodring to you there is nothing more to do for here, and I guess I will have to get the hardware checked for malfunction.
