At work we have around 10 Dell Latitude 5590 laptops (Intel Core i5-8350U) that won't connect to wireless display adapters (Microsoft Display Adapter. Yes, they have the latest firmware installed). I've already tried some things: the obvious ones like updating BIOS, drivers and Windows.

What to Know On some Dell systems, you can toggle Wi-Fi on and off using the Fn + F2 shortcut. Or, press Win + A. Select the arrow next to the Wi-Fi symbol (W11), or press Network (W10), to pick a Wi-Fi network. Some Dell PCs have a Wi-Fi switch that you must turn to the On position.
If this doesn't work, test seeing if your laptop will connect via Ethernet. If so, then your WiFi card may be going. You can either look to replace it/have it replaced, or get an external (plugs in via USB) WiFi card.
Boot the laptop into the BIOS (tap rapidly on the F2 key as the laptop starts up), and look at the NIC port on your laptop to determine whether the Ethernet ports LED lights are on, off, or flashing: If the LEDs are on or flashing, then your laptop is picking up your network and a connection is in place. Go to step 6.
When you want to disable all the wireless connections on your Dell laptop, such as when you are on an airplane, you can enable Airplane Mode (Flight Mode). You can also disable individual wireless devices (Wi-Fi, Bluetooth, or Mobile Broadband) while leaving the others enabled.
