My WIFI will disappear or disconnect automatically

[Mitch52301]

I have a pavillion dv7 6135dx, and lately I have noticed that my wifi will disconnect all of a sudden, or when I start up the computer I won't show any networks to connect to. 

Now when this happens I run the troubleshooter, and that will fix the problem, but i will get an error message at times telling me that no adapter is found.  I am not computer saavy as some, but with a little research I can usually find my way if pointed in the right direction. 

So, is my wireless card going bad, and if so will the realtek RLT8188CE work on my machine. I have looked at youtube for replacing the card, and seems to me that its pretty straightforward, and only takes about 5 mins. I am also a bit unclear as to what a whitelist is?  Does that mean that if the card is on the list, then it will work? I will admit, the terminology I am not to familiar with so thats why I am a little confused. 

Any help will be greatly appreciated.

Thanks 

Mitch

Hi! @Mitch52301, Welcome to HP forums.

I understand you have wireless connection issues with your PC.

Don't worry I'm here to help you out.

Did you make any software or hardware changes on your PC?

Are the wireless drivers listed in the device manager?

Excellent description and a great diagnosis done. It is greatly appreciated.

Please share the product number of your PC to assist you better.

If you are connecting your PC using a wireless connection try updating the BIOS, chipset and wireless drivers on your PC and check if it helps.

Update the BIOS using this link. Click Here

Note: Before uninstallation of the wireless drivers make sure your PC is connected via ethernet cable.

Refer this article to know more information about using HP support assistant.

Try the steps recommended below to solve the wireless issue with your PC.

Click the Start Button.
Type “Device Manager” and press Enter.
Click Continue if prompted.
Click the [+] next to Network adapters.
Right Click on “Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC” or similar Wireless card.
Click Properties.
Click on the Advanced Tab.
Click on 802.11d.
On the right-hand side change the drop down to Enabled.
The  following steps are optional but may help:
Select TX power level.
On the right-hand side change the drop down to 100%.
Select Wireless mode.
On the right-hand side change the drop-down menu to “IEEE 802.11b/g”.
Click OK.

Manually change network settings

Manually changing the network settings can resolve wireless connection issues. Create a restore point in Windows, and then manually change the network settings.
Using the search box on the taskbar, search for and open Create a restore point.
The System Properties window displays.
Click Create.
Type a name for the restore point, and then click Create.
Windows creates the restore point.
Using the search box on the taskbar, search for Command Prompt. In the results list, right-click Command Prompt, and then click Run as administrator.
If a User Account Control screen displays asking if you want to allow the app to make changes to your computer, click Yes.

Type the following commands one at a time, pressing Enter after each one.

ipconfig/flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset c:\resetlog.txt
netsh winsock reset
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
To open the TCP Global Settings, type netsh int tcp show global in Command Prompt and then press Enter.
Make sure all settings are disabled except Receive-Side Scaling State.
Close Command Prompt, reboot the system and then try to connect to the Internet.

Forget the wireless connection

If you’re having “Windows 10 can’t connect to this network” error, you might want to “forget” your wireless connection in order to fix this problem. To forget wireless network on Windows 10, do the following:

Open Settings App and go to Network & Internet.
Go to Wi-Fi section and click Manage Wi-Fi settings.
Scroll down to the Manage known networks, select your Wireless network and click Forget.
After you’ve done that, connect to the same wireless network again.

Refer this article to further troubleshoot wireless issues with your laptop. Click Here

If the issue still persists after trying out the steps try running a system diagnostics on your PC and check if the hardware components on your PC are functioning correctly.

Refer this article to know more information about running system diagnostics on your PC.

Let me know if this works!

Have a great day! 🙂

I updated the BIOS, and I also updated missing drivers which I wasn't aware of. I do think that was the root of my problem. 

The model # of my computer is LW174UA#ABA, and the Serial # 5CH1351NMS.

Also I wanted to let you know that I looked for Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC, in the device manager list but couldn't find it listed, I found several others but not that one. Could you please advise me on what to do about that?

These were the only ones listed.

For now I think my connectivity problems have been resolved downloading the missing drivers. However if you think there is something else that really should be done please let me know.

@Mitch52301, thanks for your prompt response and time.

I appreciate your efforts for writing back to us.

As you mentioned after reinstalling the drivers your issue got resolved.

I'm glad to know your issue got resolved after trying out the steps suggested.

Also, I have checked the records and it is Intel Centrino wireless-N6150 card shipped with your PC and not Realtek wireless card.

So the Realtek wireless card is not listed in the device manager.

If you have any queries in future related to any HP products, you can always reach out to us.

We will try our best to help you out.

Take care,
Have a great day! 🙂
