Wifi Adapter issue

HP Recommended
Pavillion 15p-100dx
Microsoft Windows 8.1 (64-bit)

I have been having troble with my Realtek wifi adapter, loosing connectivity every now and then. At times troubleshooting will work by Reseting the adapter and I will have my connection back. At other time post reset the wifi adapter would no longer be available and listed in Device MAnager.


Most of the times when I restart my system, it will not find any adapter in Device Manager.


I have tried everything, but no success; wiped out my system and did a clean install, updated BIOS, moved back from Win 10 to Win 8.1 (which came in my laptop), tried several drivers and still failure.


Can someone help on this...

Hi @Gomsi,


Welcome to the HP forums! It is a great way to engage, post questions and find resolutions by working with specialists in the HP community. I understand that your computer’s Wi-Fi keeps disconnecting and at times does not connect at all as the wifi adapter does not get listed in device manager. It’ll be a pleasure to assist you with this.


A commendable job was done by updating the Wi-Fi drivers ,bios and doing a clean install. You done awesome  troubleshooting before posting your question in the HP forums. It is always a great pleasure to work with tech-savvy and technically sound customers like you. Kudos to you for that. I am amazed at your technical skills and levels of technical knowledge.

At this stage, there are very few steps to recommend and it could be a possible Hardware issue with the Wi-Fi card.


Please run Wifi diagnostics on your computer.

  1. Steps to do it: Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press the F2 key repeatedly, about once every second.
  1. The HP PC Hardware Diagnostics (UEFI) main menu is displayed.

Select "component check" and run wifi diagnostics.

  • Perform a bios defaults.
  • Please check for any electromagnetic interferences in the vicinity. (Like microwaves, ACs and cell phones)
  • Please ensure the proximity of the notebook with your router.
  • Please disable the Bluetooth driver in device manager and check.
  • Please check in safe mode with networking to further isolate the issue to being software related.
  • You could also create a new user account to check to further isolate the issue.

If the wireless card is unresponsive or not detected in the diagnostics,  or if the issue still persists after trying all these steps then the wifi card is faulty and needs to be replaced. You could contact HP phone support by visiting this link: You could either send in the computer or have them ship you a wireless card if it is customer replaceable.


Let me know how this goes and hope this helps!. I genuinely hope the issue gets resolved without hassles and your computer works great.

Thanks for being a part of the HP community. Please let me know if this helps, and if it does, please mark this post as an “Accepted  Solution”. Kudos would also be appreciated greatly for my efforts to help. You could simply click the “Thumbs Up” Button.

Thanks and have a blessed week ahead!
