T460S "Configuring Mobile Broadband Device" every time on power up (Sierra EM7455)

I've been trying to fix a problem with my Lenovo T460S for months now, with hours spent on it and no success. The thing pops up with "Configuring mobile broadband device" every time from a fresh start, which takes about 30 seconds to complete. I've read this is to do with the SierraEM7455 onboard, but there is only one driver available for this on the website, and this does not fix the problem. 

 

Does anyone know how to fix this? I'm getting very frustrated with it.

Hi

There is a solution in another thread where you've posted short question about issue with em7455 - disable Selective Suspend Mode drivers.

Navigate to the folder where em7455 drivers package from Lenovo site is extracted (usually c:\drivers...). There should be Lenovo7455DriverSetup installer and Configuration.ini file. Open the latter in the text editor like Notepad. Add the following string in the 1st section [Default Values]:
SS=0

It'll disable SS mode drivers installation. Save the file, reinstall the drivers. I'd advice to remove existing modem drivers firstly.

Another way might be to edit the registry, but drivers reinstallation seems a bit reliable.

Thanks for the reply. When I click the downloaded file, it says to select a location where the software will be installed (not extracted). The automatic location is C:/DRIVERS/WIN/WWANSREM7445

 

When I navigate to this folder, I do not find either of the files that you mentioned. There is a dpinst and a 'Package' folder with various subfolders and files. I'm using Windows 10

As you probably have seen in another thread, there are two em7455 drivers packages on the support site, with different content. The package on the T460s download page is full, with files after extracting I mentioned.

I can only find one driver on the website, and this one does not help the problem. Can you point me towards the correct driver?

That's the package I've been using. I've been unable to locate a second one.

Sorry for inconvience. The recent drivers packages are repacked, have different structure and installation routines.

Do you know if it's possible to get the old driver that can fix the issue?
