The network card stops working during use

[DaG007]

The network card stops working during use.

This seems to happen after a sleep state.

Attempts to restart the network card (via Parameters window) don't change anything.

I have to restart the computer for the network card to work again... until the next shutdown!
Why???

Any ideas on how to find the cause? Fix the problem?

@DaG007, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Here's a step-by-step guide to help identify and resolve the issue with the network card on your HP ENVY 34" All-in-One Desktop (4G584AV):

Disable Power Saving for the Network Adapter

1. Press Win + X and select Device Manager.
2. Expand Network adapters and right-click your network card (e.g., Intel/Realtek/Wi-Fi/Ethernet).
3. Select Properties and go to the Power Management tab.
4. Uncheck:
   • “Allow the computer to turn off this device to save power”
5. Click OK, then restart your PC.

Update or Roll Back Network Drivers

Update:

1. In Device Manager, right-click your network card and select Update driver.
2. Choose Search automatically for drivers.
   • If it says it's up to date but the issue persists, visit HP’s support site: HP Support for ENVY 34 All-in-One.
   • Download the latest Wi-Fi/Ethernet drivers compatible with Windows 11.

Roll Back:

If the issue started after a recent update:

1. In the same Properties window, go to the Driver tab.
2. Click Roll Back Driver (if available), then restart.

Disable Fast Startup (for shutdown issues)

Fast Startup can interfere with device reinitialization on boot.

1. Press Win + R, type powercfg.cpl, and press Enter.
2. Click Choose what the power buttons do.
3. Click Change settings that are currently unavailable.
4. Uncheck Turn on fast startup (recommended).
5. Click Save changes and restart.

Run the Network Troubleshooter

1. Go to Settings > System > Troubleshoot > Other troubleshooters.
2. Run the Network Adapter Troubleshooter.
   • Follow any recommendations if it detects issues.

Check for Sleep-Related Driver Conflicts

1. Open Command Prompt as Administrator.
2. Run the following commands:

powercfg -devicequery wake_armed

and:

powercfg -lastwake

• These commands may help identify whether the network adapter is being improperly handled on wake.

Also try:

powercfg /energy

• This creates an HTML report showing power and driver issues. Look for network adapter warnings.

BIOS and Firmware Update

Check for updates from HP Support Assistant or directly at the HP Drivers Page.

• Ensure:
  • BIOS is up to date.
  • Firmware for the network adapter is the latest.
  • Chipset drivers are current (they handle power states).

Optional: Test with Sleep Disabled

Temporarily disable sleep mode under Settings > Power & battery > Screen and sleep and see if the issue stops. If it does, it confirms that sleep-related device handling is the root cause.

I hope this helps. 

Take care and have a good day.
