It sounds like Windows updates may have caused compatibility issues with the
Qualcomm QCA61x4A 802.11ac Wireless adapter, which is unfortunately not uncommon after major updates. Here are additional targeted steps to resolve the issue:
1. Check Device Manager for Errors
- Open Device Manager (
Win + X > Device Manager
) and locate your wireless adapter under Network Adapters.
- Look for any yellow exclamation marks or errors.
- If the issue persists:
- Right-click your adapter > Uninstall device.
- Restart your PC. Windows will attempt to reinstall the driver automatically.
2. Download the Latest Driver From the Manufacturer
- Even if Windows reports the driver is "up-to-date," manually downloading from the manufacturer's website often solves issues.
- For Dell PCs: Use Dell Command Update or check the Dell support website.
- For Lenovo PCs: Use Lenovo Vantage or visit Lenovo’s driver support page.
Regarding the
Qualcomm QCA61x4A adapter, try to find a compatible Windows 11 driver for the chipset:
- Visit the Qualcomm website if your system manufacturer doesn’t provide the latest driver.
3. Roll Back Wi-Fi Driver
If a recent driver update caused the issue, rolling back may help:
- Open Device Manager > Network Adapters > Right-click Qualcomm QCA61x4A.
- Select Properties > Driver tab > Roll Back Driver.
4. Test with a Clean Boot
A clean boot may identify software conflicts:
- Open
msconfig
(Run command Win + R
> type msconfig
).
- Under the Services tab, check Hide all Microsoft services, then click Disable all.
- Reboot and check if the Wi-Fi works.
5. Manually Reinstall an Older Driver
Sometimes newer drivers don't play well with certain updates:
- Uninstall the current driver via Device Manager (
Right Click > Uninstall
).
- Download a driver version from earlier in 2023 if available from Dell/Lenovo archives.
6. Use a Temporary USB Wi-Fi Adapter
While troubleshooting, a USB Wi-Fi adapter (if available) helps ensure uninterrupted connectivity.
