Intermittent network dropouts with Windows 11

Question

Hi, I would appreciate help with a connection issue.

I updated to Windows 11 in early November when MS cut off support to Windows 10. Ever since, my wifi connection has been unstable. It used to drop out every couple of minutes and require me to switch from the 2.4 to 5g signal on my router, which would solve it for a couple of minutes. Now the dropouts are closer to every 30 seconds.

Things I have done:

• All updates from WIndows Update including network drivers
• Deleted, restarted, and reinstalled driver for network card
• Plugged directly into router using ethernet cable -- problem persists
• Ran all relevant Windows troubleshooters

The weird thing is that this machine stays connected to wifi at work -- just not on my home or cafe or hotspot networks. All other devices on both networks are working fine. And again, this machine was working fine until the Windows 11 update.

The wifi adapter is Intel Wifi 6 AX 201 160MHz

The ethernet adapter is ASIX USB to Gigabit Ethernet Family Adapter

It sounds like you're experiencing significant issues with your Wi-Fi connectivity after upgrading to Windows 11. Here are some troubleshooting steps you can try to resolve intermittent network dropouts:

1. Check Network Adapter Settings: Ensure that your Wi-Fi adapter settings are configured correctly. You can access these settings through Device Manager. Right-click on your Wi-Fi adapter, select Properties, and check the Power Management tab to ensure that "Allow the computer to turn off this device to save power" is unchecked.
2. Update Network Drivers: Although you've mentioned updating your drivers, it might be worth checking the manufacturer's website (Intel, in this case) for the latest drivers specifically designed for Windows 11. Sometimes, the drivers provided through Windows Update may not be the most current.
3. Change Wi-Fi Channel: If you're using a dual-band router, try changing the Wi-Fi channel on your router settings. Sometimes interference from other networks can cause dropouts.
4. Disable Bluetooth: If you have Bluetooth enabled, try disabling it temporarily. Some users have reported that Bluetooth can interfere with Wi-Fi signals, especially on certain hardware configurations.
5. Reset Network Settings: You can reset your network settings in Windows 11 by going to Settings > Network & Internet > Status > Network reset. This will remove and reinstall all your network adapters and set other networking components back to their original settings.
6. Check for Interference: Ensure that there are no physical obstructions or electronic devices that could be causing interference with your Wi-Fi signal. Devices like microwaves, cordless phones, or even thick walls can impact connectivity.
7. Run Windows Network Troubleshooter: Since you've already run troubleshooters, consider running the network troubleshooter again after making changes to your settings. This may help identify any remaining issues.
8. Monitor Other Devices: Since your laptop connects well to Wi-Fi at work, check if there are any specific configurations or security settings on your home router that might differ from your workplace settings.

If these steps do not resolve the issue, consider reaching out to Microsoft support for further assistance, as there may be specific compatibility issues with your hardware and Windows 11.

Hi there. It sounds like Windows 11 might be the problem, not your hardware, since it happens with both Wi-Fi and Ethernet on certain networks. It could be a driver issue or a settings problem from the upgrade.

First, try resetting your network in Settings > Network & Internet > Advanced network settings > Network reset, then restart your computer. Also, get the newest Intel AX201 driver from Intel's website, not Windows Update. While you're doing that, turn off power saving for the adapter in Device Manager.

If it still cuts out, run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in Command Prompt to fix any system files. Does the problem still occur if you start in Safe Mode with Networking?
