Hi ieee488,

First of all I would like to thank you for your quick reply. Unfortunately, this did not resolve my issue.

When installing the Dell Wireless 1540/1550/1560 WiFi Driver:  Network_Driver_P73MT_WN32_7.35.317.0_A02.EXE | Update Package for Microsoft® Windows® (65 MB)

It gives me the following error;

Dell Wireless 1540/1550/1560 WiFi Driver  

v7.35.317.0 (A02) October 15, 2015  

 The update installer operation is unsuccessful.

I have saved as well the Installation Log of this error. If needed, I can provide this.

In the device manager, it keeps showing up as an "other devices" with a rectangular ! symbol, and a round ? symbol. Updating the driver from there still doesn't work.

I really have no Idea how this happened. It happened from 1 day to another without me making any changes.

Are there some other idea's / tips that can help me?

Thanks in advance.

You followed the install order?

Hi ieee488,

Indeed I did follow the correct order.

Drivers for Service Tag :

Shows the following categories.

- Application

- Audio

- BIOS

- Chipset

- Mouse, keyboard & input devices

- Network

- Serial ATA

- System Management

1. I started with the System Management;

- Systems-Management_Application_K82GG_WN32_2.1.0_A00.EXE

2.Then I started with the 3 chipset drivers;

- Intel(R) Management Engine Components Installer Driver

- ST Microelectronics Free Fall Data Protection

- Intel Chipset Driver

3. Because there is no Security category, I skipped 3, and went to 4. Intel Matrix Storage Manager.

- Intel Rapid Storage Technology Driver and Management Console

This download doesn't work. Intel Rapid Storage Technology gives me the following error;

* The setup program ended permaturely because of the following error:

"This platform is not supported"

5. Audio drivers:

- IDT 92HD93 High-Definition Audio Driver (Success)

6. Video Driver -> Because this was not in the list, I went to 7. Network Interface card or ethernet drivers. There were no Network Interface Card or Ethernet drivers (Just Dell Wireless 1540 WiFi driver and a Dell Wireless Bluetooth Driver).

I skipped point 7 as well, and went to 8. Point 8 was also not on my list, so I went to point 9. Dell Quickset. There is an application category, but this shows only: "Dell Digital Delivery Application". So I skipped this one as well and went to point 10.

10. Wireless Network Drivers:

- Dell Wireless 1540/1550/1560 WiFi Driver (Network_Driver_P73MT_WN32_7.35.317.0_A02.EXE)

This goes download gives me an error: The update installer operation is unsuccessful.

!!Installation log is safed on my desktop!!

11. Bluetooth drivers:

- Dell Wireless 380/1550/1560 Bluetooth Driver. Installation successful.

Unfortunately, the problem remains. Any other tips?

No idea.  Maybe try A01 version of the wifi driver?

No success either.

Both V01 and V00 give me the same error.

I have also entered the BIOS mode, and the WiFi card is enabled there.

I forgot to mention, maybe it will help. My computer is a: Latitude E5430 non-vPro

How about try re-seating the wifi card?

Otherwise, I am out of ideas.
