WiFi Adapter disappears after waking up from Sleep

Hello,

I know this issue has been raised a couple of times and I have read most of the troubleshooting provided on other forums but to no avail. I would like to raise this issue again with hopes of finding solutions.

Issue: When waking up from sleep, Wifi is disconnected. Checked in NCPA.CPL (network connections) that WiFi adapter has disappeared. Wasn't able to check in device manager. User have to restart to fix issue.

Laptop: Surface Laptop 3

Network Adapter: Intel(r) wi-fi 6 ax201 160MHz

Windows version 2004

Network Adapters List:

What we've done so far..

1. Checked that the Network adapter doesn't have the Power Management Tab.

2. Checked HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power and found out that it doesn't have CsEnabled DWORD. Created CsEnabled and set it to 0. Restarted but nothing happened. Still no Power Management Tab

3. No Wireless Adapter settings in Power Options.

4. Updated the driver. Asked user to test if this solved the problem but it didn't. WiFi still disconnects after sleep.

5. Reinstalled Driver -- still waiting for update from user

6. Surface support suggested the following:

     a. Restore the power plan to default settings. Power Options > Edit Plan Settings > Restore default settings for this plan.

           - Still waiting for update

     b. Please try to go to Settings > Power & Sleep > Network Connection > Select Never as an option for "when PC is asleep and on battery power,               disconnect from the network".

            - The laptop doesn't have this option. 

Please help on this.

Hello Jan YvanForbile,
go to Device Manager> network adapters, select your network adapter in use, click on the Advanced tab and disable any option related to power saving, look for the MIMO Power Save Mode option, try to set to No SMPS.

I have been having exactly this issue for about 3 days now.

My PC is an HP Envy laptop with an AMD processor and a realtek network device. If the PC goes to sleep (e.g. I shut the lid), when I open the lid again, the network adapter has disappeared from device manager. The only option is to shut it down and restart it.

I have looked at the solutions above, but they don't cure my problem (I have no hard disk, just solid state and the network adapter has no power settings in the advanced driver area)

Any help appreciated.

For me, it seemed to cure the issue when I rolled the device adapter driver back to the previous version. Can you try that?

My laptop is new and it has this Wi-Fi 6 which is new and there is no rollback option. I suspect because the hardware and driver are new, its a bug that will have to be figured out by devs.
