Wi-Fi connection suddenly disappears and I can not connect to any wireless network. 

After some attempt, WiFi connection reappears but after few hour randomly desappear.

Tried to reset connection -> same as above

Driver updatet to last one available on HP website.

Any ideas?

@vittoripaolo Welcome to HP Community!

I understand that you are facing Broadcom BCM43142 issue.

Do not worry. I will try to fix the issue.

Would you check this setting?

• Go to Device Manager
• Click on the network adapter to expand the list
• Right click on the adapter listed and choose properties
• Click the power management tab
• If "allow the computer to turn off this device to save power" is checked, please remove it.
• Click OK
• Repeat the above process any additional adapters listed.

Here is a link to  HP PCs - Troubleshooting Wireless Network and Internet (Windows 10) that may also help.

Thank you for the suggestion. It was the only test I hadn't done yet.
I have tried the solution and it seems to have solved the disconnection problems.

The problem remains at power on or after a restart. The WIFI card is struggling to find the networks and when trying to connect, the message "cannot connect to this network" often appears. I have to wait a few minutes and try several times for it to establish a connection.

I know it's a bad quality WIFI card so I ask you if is there any chance to replace it with a better one, best if dual band (2,4GHz+5GHz)?
Is there any compatibility issue due to BIOS blacklist?
Can you suggest me one compatibile with my laptop?

Thank you

@vittoripaolo

I understand your concerns.

A few things to remember are mentioned below: 

The compatibility of your router with the wireless card, 

If the wireless card is 1x1: supports 2.4 GHz and below - slow connection and download/upload speed, 

If it's 2x2 or more: support 5 GHz and above - Fast connected and speed. 

 
Here are your Product specifications: Click here for details. 

Your product Supports the following WLAN formats:

● Realtek RTL8188EE 802.11 b/g/n 1x1 Wi-Fi Adapter

Thank you for the reply.
On page 3 of the manual I read "Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + BT 4.0 Combo Adapter non-Vpro" can be used as well for the ENVY 17 model (that's my model).
Probably the best choice is to have an external USB WiFi adapter to have top performances.

Thank you again for the support.
Have a nice day you too!

@vittoripaolo

Yes, you are correct. You can go for the external USB WiFi adapter.

It will work.
