Hi Young_Clint,

Welcome to the Community,

May I know the Windows version  installed and error message you're getting while trying to install the driver(if any).

Also check and confirm if DW5550 WWAN is getting detected in Device Manager(Other Devices).

Thank You

It is in Device manager, under "other Devices". Error is that it cannot find drivers, I have also treid to search/download from Dell Site. I have Windows 7 32b

Try this Dell Wireless 5550 HSPA Mini Card driver: lt.dell.com/.../lt.aspx

If it does not get installed,try the previous versions given on the same link(click on drop down for Previous Versions).

None of these work, keep getting "Authentication failed. The Dell HSPA Mobile Brooadband Mini Card cannot be installed on this computer, please contact Dell support for further information"

1)  If it is saying authentication failed, try running the installation as administrator.

2) I don't think you need it for the driver installation, but do you have the SIM card?

I have run as Administrator, still authentication failed, And the sim card is in.

Hi Young_Clint,

Two things you may try:

1.Update BIOS  and then try to install the driver: lt.dell.com/.../lt.aspx

2.Create a new temporary user account(with admin privilege),login to the system with new user account and then try installing the driver.

Let me know if this helps.

Note:While updating BIOS,AC adapter should be plugged in,Battery should be adequately charged(more then 10%) and all external peripherals(USB devices) should be disconnected from the system.

I have updated my Bios, this is still not working

Hi  Young_Clint,

Please post a screen shot of Device Manager(expand Network Adapter and Other Devices). Please check  and post back the hardware Id of the WWAN card(right click on card,select Properties,select Details,in drop down select hardware Id).

Also may I know in which region you're using your system? Did you try installing driver with new user account?

USB\VID_413C&PID_818D&REV_0000

USB\VID_413C&PID_818D

That is the hardware id's under other devices, I cannot send a screenshot, cannot paste it in this box. I cannot add a user, my pc is on a domain

Hi Young_Clint,

I've checked and I cant find any other driver for  DW5550 WWAN card.To rule out any issue with the hardware(card),if possible try checking the card on a different system.

Hi,

I got exactly the same problem like Young_Clint.

Did you find any solution to install the DW5500 WWAN card driver?

Hello I had this exact same issue, not sure if it relates to your problem as this is an old thread, but in my case, I used the DW5550 out of my Latitude 5520 and installed it in my Latitude 5530, when trying to install the application/drivers i received the same error. The WWAN that im using is an Ericsson, and the drivers are platform locked, ie. you cant use a WWAN card from the Latitude 5520 in a Latitude 5530 or can you?

Well, the truth is you can, however you need to reverse engineer the MSI and extract the drivers, i'm not going to go into detail on how to do this in this post, but should you require the drivers for the DW5550 that will not work on any platform (Well the ones of tested) you can reply to this post.

Obviously this is not supported by Dell, but platform locking a driver file in my opinion is unnecessary.

Regards

hello,

i have a latitude 5430, i also have the same problem.

do you have a fix
