MIssing my network controller driver after re-installed windows 7

Just re installed windows on my laptop and I wasn't sure which drivers I was supposed to install and came across this. In device manager under the other devices tab there is:

Network controller

NVIDIA stereo controller

PCI simple communications controller

Unknown device

Hi Luke1101,

Please share the system model and operating system installed. 

You might need to install the chipset, video and the wireless card drivers for your computer. You may follow the steps below:

• Click on the below link: http://dell.to/QjjZDA
• Enter the Service Tag of your system and select the operating system.
• Select the category (like chipset, video) and click on the driver available.
• Download and install the drivers by following onscreen instructions. 
• Restart your computer. 

If the issue persists, you may send me the system service tag via private message (click my username and then click Start Conversation).

Please share the findings. 

I installed the drivers following those steps and it was starting  to fix things such as my internet, but the next time I went to turn my laptop on, instead of loading windows is said "invalid partition table" and now I can't login.

Edit: Uh never mind, when I removed the usb with the drivers on it from my computer, windows started up. Also, when I entered my service tag it had 27 drivers I could install but I only installed the 7 from chipset, video and network. Should I download the other ones? I noticed that things like the turbo boost icon don't pop up when I turn my computer on like they used to.

Thanks

Hi Luke1101,

In order to provide you the direct links for the drivers that needs to be installed on your computer, I would need the service tag of your computer. You may send me the system information via private message (click my username and then click Start Conversation). 

Please reply with information.

Hi, I have a similar problem. After a blue screen crash I reinstalled Windows 7 on my Vostro 3750 and cannot connect to the internet as several drivers are missing. I called the Dell helpline and, after the telephone line got cut a couple of times, finally got to speak to someone in IT who helped me locate 2 drivers I'd need, R294380 and YPYJF and then, before I could install them, the call cut again. I've been round in circles with this so many times, can anyone help? I seem to have installed the networikk driver OK (R294380 so that the adapter is working but I still have yellow triangles against all my driver files and can't connect to the internet even via cable. I'm not sure how to install the YPYJF (wifi driver) but have tried pointing everything to the parent folder via the device manager and nothing is picking it up. Any advice greatly appreciated, 2 days into this and I'm still not much further on and Dell's 902 phonelines (I'm in Spain) don't seem capable of holiding a call for more than a  few minutes.

In Device manager what are the ? marks showing under other devices,Try enabling the Wifi using Fn F2 or Wireless switch and let us know the Status on Device manager. Double click on the Network Controller with ? or !  (Assume it shows under Other devices?) go to details tab -> Change the drop down to Hardware ID - Post the info given below in the box. We can find the driver based on the info.

Hi Veejdeej, thanks very much for the response. Fortunately I was able to get through to technical support again and get the drivers needed to get the wifi up and running again, however I still have several drivers missing (all listed under Other Devices with !):

PCI Simple Communications Controller

SM Bus Controller

Unknown Device - Hardware ID: ACPI\SMO88'00

Unknown Device - Hardware ID: USB\VID_138A&PID_0011&REV_0078

As the internet is now working fine, I'm not sure what, if any, impact the lack of these is having on PC performance - I'm still reloading software lost after I reinstalled Windows 7 Pro to try and get back to the funcionality I had before.

One thing that I have lost is the fingerprint recognition software. I managed to find a link to the driver, but when I tried to install it it said that other necessary files were missing, so I presume I need to do a complete reinstallation of the software. Do you know how where I can get this?

Thanks!

Hi rampster,

SMBus: ftp.dell.com/.../R292605.exe

Unknown Device1: ftp.dell.com/.../R292744.exe

USB 3.0 Driver: ftp.dell.com/.../R299161.exe

Card Reader: ftp.dell.com/.../R294157.exe

Unknown Device2: ftp.dell.com/.../R292686.exe - Validity Sensor - Fingerprint

TouchPad drivers for Multitouch: ftp.dell.com/.../R301431.exe

Audio Drivers: ftp.dell.com/.../R297834.exe

QuickSet App: ftp.dell.com/.../R299707.exe

Additional drivers given for better functionality - All drivers above are for Vostro 3750 - Windows 7 64 bit.

Visit ftp.dell.com/.../vostro-3750.html for accessing other Win XP/Win 8 drivers for Vostro 3750

p.s. could it be that I need to download the fingerprint software again first before I install the driver? I don't know where I can obtain the software.

Hi Veejdeej,

Thanks so much for providing the links to these drivers. I've installed them all on my Vostro 3750 (Windows Pro 64 bit) and all have worked, except:

Unknown Device2: ftp.dell.com/.../R292686.exe - Validity Sensor - Fingerprint

It is still staying it cannot find the drivers for this device, even after I've done the installation, and the fingerprint software still doesn't work. Any ideas on how I can resolve this greatly appreciated.

Many thanks,

Catherine

On my original order it is liseted as "Palmrest: Fingerprint Reader Biometric"

you should have got the resource cd or drivers and utilities disk from dell which would contain the drivers and application. Or you can download them from http://smartsource.dell.com.  or go to the last link in my previous post and download ST Microelectronics DE351DL Motion Sensor drivers. If you still see unknown driver then right click on it and choose update driver then choose download or search from internet and download.

The final link solved the driver problems, thanks! The fingerprint reader still isn't working though (I don't get the option to swipe instead of enter my password when I restart the PC). I didn't get a software disk so I can't reload the software from  it. I tried the smartsource link but when I click the button to register my computer nothing happens. I've now registered it through a dell account, but is there another link I can try to download the software?

Rt click on the Internet explorer thru C:\Program Files (X86)\Internet Explorer\iexplore.exe and choose run as Administrator and then go to https://smartsource.dell.com and then try Register button, then click Install (SysProf##) or something would come... This would fetch your service tag from your computer to register. You can see the softwares that were shipped along with the computer. Thru this you can get webcam central, Mcafee and Fingerprint as well i think. Please check.
