Unexpected Wifi Disconnection on New PC
florylie -
Hello,
We just acquired a new HP Pavilion Laptop 15 with Windows 11
AMD Ryzen - 8 GB of RAM.
Everything works very well except the Wi-Fi, which disconnects randomly every day (4 to 5 times a day or more).
I have to run the "Windows Network Diagnostics" which tells me that a network cable is not connected properly or is damaged, and that the issue with the wireless network card or access point is fixed, in order to recover my Wi-Fi connection.
All our other devices work perfectly and do not disconnect.
Could someone please tell me how to stop this from disconnecting?
Thank you in advance for your responses.

Hello.
Go to Device Manager, then to "Network Adapters," right-click on your WiFi network card and select "Properties." In the window that appears, go to the "Power Management" tab, uncheck the box that allows your card to be turned off to save power, then confirm by clicking OK. Restart your PC and check if it’s still the same. Also, provide me with the exact name of your WiFi network card as it appears in Device Manager.

A hello, a response, a thank you are always appreciated.
Hello.
What Wi-Fi card is installed on this laptop?
It's possible that the driver installed by the operating system may not be the best one. Try downloading the driver from the manufacturer's website: brand and model. For example: Realtek RTL8821CE.
Hello Bazfile and Epiloguest,
The problem is that when I go to the device manager and look at the Network Adapter, I don't have the "Power Management" tab. I'm on Windows 11, maybe this tab has disappeared, or is somewhere else, but I can't find it.
What should I do?
Otherwise, the network card I have is a Realtek RTL8852AE Wifi 6 80211as PCIe Adapter.
When I try to update it from the Device Manager, it says "The best drivers for your device are already installed."
Which website can I go to in order to try to download the updates?
Hello,
It's not a network problem, at least I don't think so, but first we need to know what this network is made of and a copy-paste of the Wi-Fi connection content from settings> network> wifi>properties button copy and paste the result here.
like this:

Good evening Brupala,
Here is the copy-paste of the wifi connection
Epiloguest,
what do you mean by the PC environment?
OK, thanks,
So, you are connected via AC wifi on a Livebox, on channel 108.
It might be channel 108 that's causing the problem (normally not, but as mentioned, depending on the environment, it can affect it).
I don't know if it's possible, but check on the LBX if you can configure another channel in 5 GHz, below 100, for example channel 42.
Ideally, it would be good to scan with a proper app, for example inSSIDer to see the least crowded channels, knowing that channels >100 are subject to DFS.
Hello Epiloguest and Brupala,
Regarding the environment, it seems unlikely to me; the laptop is placed 2 meters away from the router, and I had no issues with the old laptop.
Otherwise, about the channel, why change it? It's set to automatic, and why on 42 and not on another since there are plenty of others?
Sorry to ask these questions, but I'm a bit hesitant to touch anything that's already on automatic.
Have a good day.
Hi,
If you don't want to change anything, you don't change anything...
I said 42 randomly, but I think on lbx, it suggests 40 instead, and I explained to you that DFS channels can cause problems under certain conditions.
On the other hand,
at 2 meters from your box, I strongly recommend that you connect with a direct ethernet cable; you'll be fine if you want to connect for hours.
Since your ultrabook probably doesn't have an ethernet port, I suggest you invest in a gigabit/usb-c adapter
Yes, the box is indeed 2 meters away from the PC, and I found it more convenient not to have any wires on my laptop when I use it, especially since I often sit on the couch (which is in the same room as the Box) but is more than 2 meters away from the Box, so a wire is not very practical, but of course I can also connect via Ethernet.
Your problem may also come from software you have installed that is disrupting your connection, otherwise you have USB WiFi adapters.
To see:
Download FRST once downloaded save it on the desktop then right-click on FRST and choose Run as administrator you will have this:
Click on Scan
Be careful, wait for the messages saying that the scan is complete to appear.
At the end of the scan you will have two text files on the desktop FRST and Addition.
Then send the FRST and ADDITION reports to PJJOINT then provide the two links generated by PJJOINT in your response.
The FRST report is not complete but well, we'll make do.
Regarding your connection, the only software that might be an issue is HP Connection Optimizer, I don't really know what it's for, apparently to optimize the connection ? It's up to you to decide.
Your PC is apparently a HP Pavilion 15.6 inches - 15-eh1000, if that's the case, here is the driver download page, check in network drivers for the latest one for your WiFi network card, it's from April 11, 2022.
Nothing else to add.
This software is a piece of software that was pre-installed on your PC. You have an HP PC, so you have applications from HP; if you had a PC from another brand, you would have had software from that other brand. Most of this software is unnecessary since if you reinstall Windows without going through HP's recovery, your PC will work just fine without these bloatware programs that are originally installed by PC manufacturers.
