Realtek RTL8852BE-VS WiFi 6 802.11ax PCIe Adapter

[Mbh68]

My new HP laptop gets on  my WIFI 5 network with Realtek RTL8852BE-VS WiFi 6 802.11ax PCIe Adapter but every few minutes loses internet connection.

I seem to have the up-to-date driver installed.   6001.15.152.0     16/04/2024

Any ideas on how to solve this issue?

It may be going to sleep and taking too long to wake up

The Wi-Fi device has a Power Management feature as shown below. If you un-check the box "Allow the computer.." then the Wi-Fi device will be enabled during sleep and will not have to be woken up when the computer resumes from sleep.

Thanks for your reply,

but Realtek RTL8852BE-VS WiFi 6 802.11ax PCIe Adapter

seems not have Power Management, i do not found it?

The problem occurs when using the browser, not after a break ...

Laptops in modern standby do not have that option according to Microsoft. I was unaware why that power option was missing on some systems and present on others and read about it a few minutes ago..

Try this driver that our senior expert @Paul_Tikkanen listed back in Dec 2023

Hi, @BeemerBiker 

@Mbh68 has a newer version of the driver already installed, (6001.15.152.0  16/04/2024) so I would be very surprised if the older driver would fix the problem.

Possibly the WiFi signal is weak.  Your adapter has "WiFI 6" and possibly your modem does 2.4, 5 and 6ghz band.

Try selecting or forcing one of the bands. 

From ChatGPT (OpenAI 3.5)

The 2.4 GHz, 5 GHz, and 6 GHz Wi-Fi bands each have distinct characteristics that make them suitable for different use cases. Here's a comparison of these bands:

2.4 GHz Band

• Range: Longer range, better at penetrating walls and obstacles.
• Speed: Lower maximum data rates compared to 5 GHz and 6 GHz bands.
• Interference: More prone to interference because many devices (e.g., microwaves, cordless phones, Bluetooth devices) operate on this frequency.
• Channels: Fewer non-overlapping channels (usually 3 in most regions), leading to potential congestion.

5 GHz Band

• Range: Shorter range compared to 2.4 GHz; less effective at penetrating walls and obstacles.
• Speed: Higher maximum data rates, making it suitable for high-bandwidth applications like streaming HD video and online gaming.
• Interference: Less interference compared to 2.4 GHz because fewer household devices use this frequency.
• Channels: More non-overlapping channels, reducing the likelihood of congestion.

6 GHz Band

• Range: Similar or slightly shorter than 5 GHz due to higher frequency.
• Speed: Even higher maximum data rates than 5 GHz, ideal for the latest high-bandwidth applications and future-proofing.
• Interference: Currently the least interference as it is less congested, being a newer band with fewer devices operating on it.
• Channels: Significantly more non-overlapping channels, greatly reducing congestion and allowing for more simultaneous connections.

Use Cases and Considerations

• 2.4 GHz: Best for general use, especially in larger homes or environments with many walls and obstacles. Good for devices that do not require high-speed connections, like IoT devices.
• 5 GHz: Ideal for high-speed applications and environments with fewer obstacles. Great for apartments or open spaces where range is less of a concern but higher speeds are needed.
• 6 GHz: Best for the latest devices that support this band, offering the highest speeds and least congestion. Ideal for very high-speed internet connections and dense urban environments with many Wi-Fi networks.

Compatibility

• 2.4 GHz: Supported by almost all Wi-Fi devices.
• 5 GHz: Supported by most modern Wi-Fi devices.
• 6 GHz: Supported by the newest Wi-Fi 6E devices.

You can possibly recommend a band if you have these options

Alternately, log into the modem and specify a different SSID (name) for each band. I had to do that to force my iPhone to use the 5ghz band

Thank you for your message, but my Wifi signal is not weak, I am 2m from the Box.
I also use it with smartphones without any problems.
The problem only exists with my HP laptop and since the purchase about 6 months ago, I am already on the fifth version of the driver without ever resolving the problem.
The Internet connection is interrupted, but data are still exchanged, I installed a counter. To get the Internet working again, I just need to disconnect from the WiFi connection and reconnect.
The Internet connection comes back immediately for about 10 to 15 minutes and then there is an interruption again.

I'm not sure if the problem is related to the driver?

This could still be a sleep problem.  Your system is powering down the network when it is idle.  Please verify you are in modern standby

Modern standby is explained here

If you are using Modern Standby then your bios is configured to use S0.

Please copy and paste the following command into Windows Command Prompt using Administrator mode.

powercfg /a

Should look something like this:

If there is a problem with modern standby possibly your BIOS setup has the option to use S3 instead of S0.

If not, then this article explains how to disable it. If you decide to try disabling using any of the methods explained, be sure to set a restore point in Windows to make it easy to return to s0 state.

If getting out of modern standby fixed the problem, I would contact HP and make a warranty claim.

You might also look at some sleep diagnostics and try the two command shown here

My laptop uses S0

I said 10 to 15 minutes but the disconnection time is totally random.

The problem is indeed related to power management, I changed the settings in Windows (performance, long time) and the problem has almost disappeared.

Can we remove the power management at the Wifi adapter?
