Question

Internet or WiFi gets disconnected after Sleep in Windows 11

Jolta 21

After updating my Win a few weeks ago on my Dell laptop, WiFi keeps getting disconnected after Sleep in Windows 11. I had to restart to system to get connected. Wifi shows connected to the router but no internet. There is an internet connection on the router but looks like something blocks it after the sleep mode.

Hello Electricvehicle,

The most probably causes are:

Driver issue: Check for updated drivers on your Wireless NIC manufacturer website if Windows Update doesn't have any specific update for it
Power saving enabled for the device, causing it to deauth from the BSSID: From the Device Manager, go to the properties of the Wireless Interface and in the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box
IPv6 issue: Disable IPv6 from the properties of the Wireless adapter
Disable your Bluetooth adapter if you are not using it
Disable your LAN ethernet adapter if you are not using it

Additionally you may want to check in the forums of your router manufacturer for similar issues, and there may be firmware changes that apply for this issues. One thing you can try is to check if it happens the same when connected to a different router or your phone's hotspot. If it doesn't reproduce the issue then the router would be the problem.

I cannot find any power management tab for the wireless interface. Does this mean that every time I sleep the PC will have to reboot to get a network connection?

I had this same problem on Win10 with a Dell and then an LG. I was hoping it would be resolved by now. It doesn't happen always, but I do often have to reboot, which completely defeats the sleep/hibernate function.

After update of Win11 power management tab of Lan card properties is gone. I hate those windows updates

I tried every solution on the internet but none of them worked. The only solution i found is format. But I want you to know that the problem emerged from my first format. I did my first format without shutting down the computer. I don't remember how made it. Probably win11 things. Then it was fixed when I formatted via USB.
