Issues with Wifi disconnecting upon restart or Sleep mode - Windows 11 - Lenovo Slim Yoga

Question

Hi

I wondered if you could help me please I have had a persistent issue for sometime that I cant seem to resolve on both my laptop - Lenova and my daughters HP.

So in essence the Wifi keeps disconnecting upon restart/power down. The internet is Gigaclear and is working/operating fine on other devices.

To get it to work I have completed the following solutions

1. Disabled Power Saving Mode - I don't seem to have a Power Management Tab in my Network driver (INTEL (R) Wi Fi 6E AX211 160MhZ). I have researched how to reconnect this tab but nothing has worked to date. I have noticed the tab does appear on the Bluetooth wireless tab
2. Updating or Reinstall Driver - I have completed this several times following online video's and I have to say it has NEVER worked.
3. Run Network Reset - I have completed this several times followed by Command Prompt resets - This has worked on each occasion but it is starting to get annoying as i need to do it every time and doesn't offer a permanent solution.
4. Network Troubleshooting has been completed several times but again doesn't offer a permanent solution.

Please help as it is driving me mad.

Kind regards

Welcome James muir,

Thank you for reaching out to Microsoft Q&A forum.  

I understand how frustrating it can be when Wi‑Fi disconnects after restart or sleep on Windows 11 devices, and the connection only recovers after performing a network reset. 

To speed up the resolution, please confirm the following:  

• Does the Wi‑Fi fail only after Restart or Sleep, or also after a full shutdown and cold boot? 

In the meantime, you can try the workaround steps to troubleshoot the issue:   Option 1: Disable Fast Startup 

• Open Control Panel by searching on Start menu > Power Options > select Choose what the power buttons do 
• Select Change settings that are currently unavailable 
• Uncheck Turn on fast startup 
• Restart the device 

Option 2: Check WLAN AutoConfig service 

• Press Windows key + R > type services.msc and press Enter 
• Locate WLAN AutoConfig 
• Make sure Startup type is set to Automatic 
• If the service is running, restart it 

Option 3: Update system firmware and chipset 

• Go to the device manufacturer’s official support website 
• Install the latest BIOS/UEFI and chipset drivers for Windows 11 
• Restart the device after installation 

Option 4: Reset network adapter advanced settings 

• Open Device Manager by searching on Start menu > expand Network adapters > open the Wi‑Fi adapter properties 
• Go to the Advanced tab 
• Restore all values to default 
• Restart the device 

5, Disable Wi‑Fi power saving at system level 

• Open Control Panel by searching on Start menu > select Power Options 
• Select Change plan settings for the active plan 
• Select Change advanced power settings 
• Set both On battery and Plugged in to Maximum Performance 

I really hope that the information I gave above was helpful to you. Please feel free to reply below and let me know if you have further concern on this matter.
