I have an Inspiron 5515 that's past the warranty expiration of January 2023. For some unknown reason, my network adapter keeps losing all of the networks that are available (meaning when I look at the available networks, the list is empty and it says there are no networks found), and through trial and error I found that if I go to Windows 11 troubleshooting and click "Restart the Wi-Fi network adapter" button, that temporarily fixes the problem (sometimes for 5 minutes, sometimes for 24 hours) and I'm back online. This always works but it doesn't stay working. I'm at a loss for what to do next.

My network adapter is a "Qualcomm QCA61x4A 802.11ac Wireless Adapter" showing date 5/19/21 and version 12.0.0.1118.

Here's what I've done to try to fix the problem:

1. System > Windows update: already up to date
2. System Restore: nothing to use before 4 months ago (April 2023), and when I tried to go there my computer wouldn't start, so I had to go back to my current setup
3. Device Manager > Network Adapters > Qualcomm QCA61x4A > right-click to update driver: already up to date
4. Device Manager > Network Adapters > Qualcomm QCA61x4A > right-click to disable driver, the right-click to enable it: that gets me back connected, but it goes out again
5. Device Manager > Network Adapters > Qualcomm QCA61x4A > right-click on Properties > Driver tab > Update Driver: already up to date
6. Device Manager > Network Adapters > Qualcomm QCA61x4A > right-click on Properties > Driver tab > Roll Back Driver: rebooted then still had the problem with the previous version of the driver, then I located and downloaded a new copy of the current driver and installed that, then rebooted and still had the problem
7. Used the Dell drivers & downloads page to analyze my system and update the Qualcomm driver. The version is still 12.0.0.1118.

Anyone have an idea? I don't even know if this is hardware or software, though a software reboot of the adapter always temporarily works.
