Windows 10: Windows 11 Wi-Fi showing not available after sleep

Windows 11 Wi-Fi showing not available after sleep. My wifi card is mediatek wifi 6 mt7921 wireless lan card. The wifi shows no notwork available after it goes to sleep. This issue was not there at first, it happened after I reseted my laptop and yes I have updated the drivers. If anyone know the solution please help

Laptop won't show list of available networks

We suggest checking the list of available Wi-Fi networks on your laptop.

Please follow these steps:

• Click the Windows logo.
• Go to Settings (gear icon).
• Select Network and Internet.
• Then Wi-Fi.
• Make sure the Wi-Fi radio button is On.
• Select Show available networks, then you'll be able to see the list of available Wi-Fi networks.

Update us with the outcome so we provide further assistance.

 

Losing Wi-Fi AFTER Sleep

I noticed there are WDKs for 1903 and 2004 yet none listed for 1909 (which apparently you use).

I suppose you could try scripting turning Airplane Mode on then off again to see if it will force a re-scan of the Wi-Fi card (I think it uses WUDFHost.exe). Brink did this using compiled AutoIt scripts for Windows 8.

Alternatively, have a look at powercfg.exe and, in particular, check the sub-group GUID for Wireless Adapter Settings:




With this in mind, and going back to your first post, the pivot point seems to be how consistently your Wi-Fi adapter is successfully enumerated after a sleep state. AFAIK only something like traces using the WHLK or WPA can determine this. Microsoft's advice is:

I suggested the use of devcon.exe as it can force a re-query of hardware, i.e. it's possible to script the equivalent of 'Scan for hardware changes' in Device Manager's GUI... so at a completely different (ACPI and/or PnP) level to network/Wi-Fi settings after hardware is initialised and identified.

I've found several posts where devcon.exe was used or suggested for similar hardware resume issues.

EDIT: Ignore my powercfg.exe suggestion. On re-reading, you've already tried this.

 

wi fi connection

After windows 1903 update I don't have any wi fi connection or icon showing and have tried many suggestions on how to get it, but none have worked.

Can you provide a step by step instruction on how to get wi fi icon and network.
