As pointed out in the thread, bluetooth may be switched off.
If the blue light (above F10, immediately R of green wifi) is
unlit, check if the sliding switch on the side (R of <return>
key) is in its central position. Towards the screen is off,
central is on, towards you is a momentary position that AIUI
requires configuring for a proprietary effect[1].
If you use wifi, then it'll be on already.
You might also check on:
$ /usr/sbin/rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
6: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

The wireless switch on your Dell computer uses the Dell Wi-Fi Catcher Network Locator to scan
specifically for WiFi WLAN in your vicinity. For more information about the wireless switch, see "Dell
