After the last update for Windows 11 insider (Home). The driver for the wireless card stopped working. There is already a guide on the issue on Intel's boards, but it is not working either. So i think the issue is with the Windows.

I have this problem already since January I think: sometimes I can work without does and than the problem returns, very frustrating. I have an Lenovo idea pad 3 15iil05 and yes that **bleep** Intel Wireless AC9560 gives me the error code 43. I removed them, I downloaded the latest drivers at Lenovo, but it doesn 't solve the problem:-(.

Anyone?

@Fabian_nl I have the exact same laptop. This problem has happened to me multiple times I have brought it to Best Buy twice now to get it fixed. But the problem always comes back. It might be 2 weeks or 6 weeks, but it never fails to fail me.

The only reliable temporary fix we have found is to open device manager, remove the device, then shutdown the laptop (not reboot. Shutdown.) When the laptop powers on the driver has been reinstalled and works. No need to leave it powered down for any amount of time.

The problem comes back every 2-3 weeks, and we repeat this process. I keep monitoring this post hoping someone will find a permanent fix, but until then I hope this temporary fix will help people who are in a bind.

@OussD I have recently just got this fixed in my Lenovo y740 laptop. Similar problem, lots of connectivity issues, code 10 with the driver. Turns out the WiFi card was not properly secured to its position from the factory and had jostled loose after a year or so of use. Simply reseating it to its correct position was enough to cause it to work again. Hope this helps others looking for a solution!

Now With proprietary drivers installed. I have no problem running on hybrid mode, everything works fine But when I go to my bios and turn on dgpu mode, arch boots but the screen starts flickering, the second there is any gpu load - more the load, the greater is the flicker.

I am experiencing the same issue, with any driver after version 450.119 in any Linux distro. Linking my forum post here, I found the root cause to be the Nvidia driver identifying the connection between display and gpu as DP 1.4 instead of DP 1.2 and sending higher bitrate signal on it. (Check the screenshots linked in the post).

Opening this after months, and glad to see that we at least know whats causing it now. The next obvious questions are can we change that connection link in the driver by ourselves or, because drivers are closed source, how do we get this across to an nvidia dev. Because the chances they stumble across our posts and actually take notice is close to zero.

So is it safe to say that Nvidia will never fix this issue? Our Legion y740 laptops are just always going to be broken moving forward? This was fixed in the Windows driver over 2 years ago. What a shame.
