I've got a Dell Precision 3541, and I'm having a really frustrating issue where the Wi-Fi and Bluetooth chips keep disappearing. This started happening shortly after I upgraded to Windows 11. Usually, I can get them back by restarting the USB hub in the device manager, but every now and then, I have to do a fresh install of Windows to fix the problem. It's gotten so bad that I switched to Linux (Ubuntu), thinking it was a Windows problem. But just three days ago, the same issue happened on Linux. Both Wi-Fi and Bluetooth showed no hardware detected at all. A hard power off and restart fixed the problem, but it happened again the next day. I'm completely at my wits' end—any suggestions on what I should do? Also worth mentioning, there are three other Dell laptops at home, all different models, that started having similar issues around the same time. Two are on Windows 11, one is on Windows 10, and mine is now on Ubuntu.

You might want to check if you're accidentally hitting the Fn + PrintScreen shortcut, which can disable or enable the wireless card on these Dell laptops. It's a common issue!
Make sure you have the latest BIOS version installed. Sometimes, BIOS updates can fix such issues; I had to reflash mine when I faced similar problems.
Sounds like a hardware problem, especially since multiple Dell laptops in your house are experiencing this. Are they all the same model?
No, three are Precision models (different versions) and one is a Vostro.
Just to clarify, are you using the built-in Wi-Fi/Bluetooth module or a USB adapter? If the USB hub isn't resolving the issue, there might be a loose connection or something shorting out somewhere.
I’m using the built-in module. I was just resetting the internal USB hub in Windows.
I had no idea! I’ll definitely check that out—thanks!
