no wifi or bluetooth option

I'd suggest downloading / installing the Wi-Fi and Bluetooth drivers from your Dell Product Support page.

It sounds really frustrating, but don’t worry — this usually comes down to a driver issue or the wireless card not being detected properly.

A few things you can try:

1. Check Device Manager
   Go to Device Manager → Network adapters.

   • If you don’t see Intel Wireless / Wi-Fi / Bluetooth listed, look under Unknown devices or Other devices.

   • If it’s missing completely, the system might not be detecting the wireless card.

2. Reinstall Wi-Fi + Bluetooth Drivers
   Download the official drivers for the Inspiron 7391 2-in-1 from Dell’s support site (enter your service tag).
   Install:

   • Intel Wireless driver

   • Intel Bluetooth driver

   • Chipset driver (important)

3. Check in BIOS
   Restart → press F2 → look for Wireless settings.
   Make sure Wi-Fi/Wireless is Enabled.

4. Confirm the Wireless Card Is Not Loose
   If the laptop was opened or serviced recently, the internal Wi-Fi card (M.2 module) may be loose or disconnected.

5. Windows Update
   Sometimes Windows 11 removes or replaces drivers incorrectly.
   Run Settings → Windows Update → Check for updates after installing Dell drivers.

If none of this brings back Wi-Fi or Bluetooth, there’s a chance the internal wireless card has failed — it does happen. In that case, a cheap USB Wi-Fi + Bluetooth dongle can at least get you connected until the card is replaced.

Well I will suggest to update the windows to it latest version or reinstall the windows and try to reinstall the WiFi and Bluetooth driver in your laptop.  

Lots of good information here on this thread, hopefully M3txnt can give us an update on wi-fi/ Bluetooth soon. Like to know the fix.
