Dell Latitude D420 - WWAN Integrated Mobile Broadband
Hello.
I recently had someone bring me a Dell Latitude D420 that had been experiencing some issues.
The issues were in form of random uninstalls, I am not here to discuss the meaning of "random" but more to question how to go about replacing one of the items.
The Mobile Broadband connectivity of the device, a long with the wireless card, were uninstalled.
I have placed the wireless card drivers, found on the service tag look-up ( here ), but am now a bit miffed on how to install the WWAN card.
I turned the device over, removed the back panel, and found the information for the card to be:
WWAN
KR-0MN624
REV: A00
ESN: 5B500411
FCC: PKRNVWE725
How do I go about restoring the functionality to this device?

Hi nccfhs,
Try going to the drivers and download (service tag look- up) page you posted and under Drivers found select All related drivers for your Product (71 files). In the list of drivers expand Communications and you will find the WWAN drivers listed.
You may need to find out which mobile broadband service provider(Verizon/Sprint etc) customer was using before you could install the correct driver and utility for the WWAN card.
Thank You

Hello Rosham,
first of all, thank you for the reply. Secondly, I've been here and done this before.
I've installed the Dell Wireless 5700 Mobile Broadband (R144966 & R220062) Utility/Firmware one uni, and the other Verizon. The utility and device are successfully installed, but the created modem, nor utility, do not detect any device.
Going to Device Manager on the computer does not show any uninstalled devices, and the card IS installed into the bottom of the laptop (see picture).
I'm miffed on this, and hopefully it ends up being something I have overlooked.

Check if wireless switch(right side of the system) is configured to enable/disable WWAN under Dell QuickSet utility.
If Dell QuickSet is not installed on the system use this link below to download and install:
For Windows XP: www.dell.com/.../latitude-d420
For Windows Vista 32 bit: www.dell.com/.../latitude-d420
If this does not help try to restore BIOS to defaults.Access BIOS screen (F2) and press F9 to restore defaults and press F10 to save and exit.
