Windows 11: WiFi gone after sleep

Go to wifi device properties using device manager, then click on power management , untick mark allow the computer to turn off this device to save power.

There is no "Wireless Adapter Settings" in the advance power settings.

Hi lch87,you have to expand PCI Express and act on Sleep as well.

I have a similar problem, although in my case the driver remains visible in Device Manager and reports no issues. And in my case, it can find various access points and even connect to my home network, but it cannot access anything outside my network (or perhaps it is a TCP protocol issue... I will test and update this comment) and it reports "No Internet" until I reboot. I have a Surface Book 3 running Windows 11 build 22622.440, although this has been an issue across multiple versions, going back to Windows 10.

I had previously fixed this issue on Windows 10, over two years ago, presumably through the Power Management tab in Device Manager, and did not have any issues after updating to Windows 11. However, I recently swapped my previous machine for a refurbished Surface Book 3 (unrelated issue), then updated 10 to 11 without first making that change, and now here we are.

The troubleshooter detects that I have no Internet connection, but its only suggestion is to reinstall my drivers. As expected, the problem persists after updating to the latest Intel drivers for my Wi-Fi hardware. I also saw no difference after making the suggested changes in the Power Options panel for Wireless Adapter Settings and PCI Express, although I don't know which Sleep options franco d'esaro has in mind.

I appreciate any assistance... but I do want to reiterate that this has been an issue at least since Windows 10 on a clean install, two and a half years ago, on a machine built, branded, and sold by Microsoft. This is not a rare issue, as there are plenty of posts online about how to fix this through the "Power Management" tab, which now no longer exists for whatever reason. I shouldn't have to go hunting for some other driver, nor dig into advanced system settings, just to be able to access the Internet.

More importantly, changing settings to prevent certain hardware from powering down does not address the root cause, as the hardware should be able to power down and then power back up. So how can we get a true fix to this issue? Not just tech support with a workaround, but an open bug report? Because sending Feedback to MS hasn't seemed to work so far.

Okay so I had this problem for months and finally solved this issue for myself, and I hope this solution might be useful for those that do not see power options in windows 10/11, so cannot manipulate the wi-fi properties for power saving in device manager, and at the same time have an integrated wi-fi/bluetooth card module. I think the root of this problem lies in power settings for many. It is beyond me why Microsoft removed those options at all when correct operation of many drivers still hinges on those settings and why they don't fix when so many people suffer from this issue but okay, let me cut to the chase.

So, neither the above mentioned solution, nor any other solutions mentioned on the internet like updating/rolling back the drivers, flushing dns, resetting wi-fi, or manipulating service files worked for me. I have the Mediatek MT7921 WiFi card, and I noticed this card integrates bluetooth and wi-fi together. When I go to device manager, right click on my wi-fi adapter and click properties, there is NO "power management" tab at all. But when I do the same with my Bluetooth driver, There IS!!

So, go to device manager, right click on the Bluetooth adapter, click properties and there (hopefully) you will see the power management setting tab that is missing in the wi-fi card. Untick "allow this computer to turn off this device to save power" tab and save the settings, et voila! I think because it is the same actual card - and because of general windows bizarreness- changing the setting for the bluetooth driver will change it for the wi-fi card too (I assume only if the card is integrated).

As you can imagine I do not know if this works for everybody. The same problem sometimes requires different solutions depending on underlying causes. Just because it is the same symptom, it doesn't mean the same disease. Just putting this out there to try because I know how I pulled my hair out over this for months and months and this ridiculous "trick" did it for me. Hopefully others can benefit.

Thanks for your suggestion. However, as you can see from below picture, there is no power management tab. If I am not mistaken, the feature of no power management tab is a common feature of Windows 11.

I have the same issue on and rog strix with a wifi 6 certified wifi board.

It worked perfectly on win 10 but 11 seems to have forgotten something along the way.

It is clearly a win 11 issue.

I tried all the stupid fixes and none work - clean reinstall, network reset bla bla bla bla.

My fix WITHOUT restart -- go to DEVICE Manager - network adapters -- wifi adapter -- properties --Advanced

And I change a property - i usually change 802.11 ax/ac/n.

I change it from ax to ac and than back again and this does the trick in a few seconds without the need to restart.

It forces a board wake up...apparently.

All of this for one line of code...i am sure....

It is lame that microsoft did not fix this issue for such a long time. It affects lots of machines.

I hate it because if I take a short brake from work I need to do this in order to restore wifi.

I will set the laptop to nonstop.

"Thank you" Microsoft for a bigger electricity bill.
