Windows 10: Windows 11: WiFi gone after sleep

My laptop is installed with Windows 11 Home Single Language and using the network adapter of Realtek 8822CE Wireless LAN 802.11ac PCI-E NIC. Every time when I put my laptop in sleep mode, the WiFi disconnected automatically, and the network adapter driver also disappeared from the list of device manager. After I restart my laptop, everything goes back to normal, but I would like to resolve this issue permanently. I have updated the driver, but the issue still persists. Below are the images that illustrate the issue. 1 WIFI gone after sleep mode. T2 When this issue happens, the WIFI icon also

Wifi gone after sleep / crash in Windows 11, adapter QCA61x4A

Dear all,

I have a persistent wifi issue that i am not able to solve since my upgrade to windows 11. I have a dell inspiron 5505 which ships with a Qualcomm QCA61x4A bluetooth / wifi adapter. The issues were not there when i still used windows 10. My mother has the same type of laptop and has the same issues.

In short:

Wifi is gone (ie: world symbol with a no parking sign) when woken after a period of sleep. Sometimes it appears that the computer did crash between going to sleep and waking up, as windows that were open when i enabled sleep mode are gone. Also in the device manager the QCA61x4A wifi / bluetooth combo is listed as a bluetooth adapter only.

I only manage to get the wifi working again after two reboots and one shutdown and start. As this only works untill the next sleep makes using the laptop very cumbersome.

This issue may seem duplicate to these for example. however they are not as my issue persists.

What I did to try solve the problem:

• Ran the troubleshooter of windows
  
• Updated drivers
  
• Renewed windows 11
  
• Disallowed the wifi to be turned of to save power
  
• Switched off link state power management
  

Unfortunatly none of this did fix my problem. Any help?

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

WIFI and Bluetooth Connection are gone after Windows 11 Update

Also had the same, but kind of resolved it after posting a thread on this forum and the Dell community.

A Dell employee did send me this guide:

https://www.dell.com/support/kbdoc/...d-or-hibernate-mode-but-will-power-on?lang=en

What i tried myself;

updated drivers with the my dell app

Enabled hibernate, using hibernate din't cause the issue, so i suspected sleep.

Disabled power savings options of the wifi card in the device manager. Also switched off link state power management in energy management. Both to no avail.

Then also switched off the activation timers in energy management.

Also downloaded a radeon (my cpu and onboard graphics is from AMD) driver that did not appear to be in the xml driver list export off the dell update app.

Lastly did the Refresh hiberfil.sys File off the Dell guide.

Do not know what fixed it but I am now two days without a single crash in sleep mode.

Good luck
