Sierra EM7455 - "Configuring mobile broadband device"

Not sure if this is a problem, more just a question...

 

I installed a brand new Sierra EM7455 WWAN module a few days ago in my X260--got it direct from Lenovo. Getting it working was a little convoluted (had to reset BIOS) but it connects just fine to AT&T.

 

The question or concern I have is when ever I restart the computer, I get a pop-up in the lower right that says "Configuring mobile broadband device...Do not shut down or restart Windows." It takes about 1-2 minutes, says "success" then everything is fine. The "problem" is that this happening every time I reboot. Has anyone seen this or know what's wrong? I've attached a screenshot of the message.

 

I installed the official Lenovo drivers for the EM7455. I tried uninstalling the Sierra package and the message goes away--but so does the WWAN module... I re-installed the driver package and now the message is back.

 

I had an X250 with the previous gen Sierra WWAN module and it was generally trouble free, no strange issues like this.

 

Thanks

Re: Sierra EM7455 - "Configuring mobile broadband device"

Hello

I'd assume the screen message follows the modem firmware applying process with customized settings for certain (AT&T) cellular operator. There is a lot of such files (cusomized fw) in the package.

You can determine the process causes that window appearing in the task manager.

Even if my assumption is correct I can't explain the reason modem's driver does it every time laptop starts (BTW, during cold start or restart, reboot?). In the past, Qualcomm manufactured Gobi 2000/3000 modems, which load operator related fw after laptop cold start. But I didn't see such delay of the process and appropriate message as it's being done fast enough and in the silent mode.

Modern modems based on the Qualcomm chips have another architecture, but includes customized fw as earlier. Modem em7455 has capabilities to switch fw image if it doesn't match sim card inserted. So, I'd assume this is a cause of befavior.

Lenovo branded modem em7455 with Sierra drivers on the Lenovo site are being configured to load default fw image for Vodafone. To change that you have to reinstall drivers with appropriate settings or, probably, there is some tool in the package to switch default image (honestly, I didn't check out that yet).

Re: Sierra EM7455 - "Configuring mobile broadband device"

Hi,

Since the last driver release (16.7.2.8 from ‎6‎.‎9‎.‎2016‎) I have started seeing the same popup every time the machine comes out of sleep. This is very annoying and inconvinient, because I have to wait 2-3 minutes before I can use the WWAN connection. I need a solution to this stupid problem.

Re: Sierra EM7455 - "Configuring mobile broadband device"

Having messed with this recently - which driver did you install? r07ws07w?

 

If you just extract it and not launch it, look in "Configuration.ini" file and add under "[Default Values]"

 

DEFAULTIMAGE=6

 

For Generic or 0..17 if you have an operator from the list. Or change:

 

FWUPDATE=OFF

 

If you don't want firmware to be automatically updated. Assuming the current firmware works OK for your operator. If not it seems you can flash it manually with FDT and be done with it.

 

Then install.

 

If you don't want to uninstall/re-install, look for "Sierra" in the registry with RegEdit and change the values there:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Sierra Wireless Inc

 

The parameters are similar but are in various Keys under this. I have not done it for 7455 but older 7355 and so on.

 

I hope this helps.

Hi TripleX1,

 

I am using nz1wn01w. There are no such files in that driver version.

Re: Sierra EM7455 - "Configuring mobile broadband device"

There seem to be different EM7455 drivers @ Lenovo. The one you mention extracts drivers *only*.

 

The one I mentioned r07ws07w "Sierra WWAN Driver for Windows 10 4441.0101" expands to "setup.exe" and "Config.ini".

 

The one you mentioned nz1wn01w "Sierra Wireless EM7455" seems more generic and expands drivers only. (though images are included too)

 

If you are running Windows 10 try the r07ws07w; if not then we need to see which driver includes a setup & config so you can modify easily.

 

Otherwise perhaps someone else has better ideas on fixing this.

Re: Sierra EM7455 - "Configuring mobile broadband device"

I'm having exactly the same problem on an (quite advanced and expensive) X1 tablet. When I tried to install the recommended driver (r07ws07w) the Sierra EM7455 configuation did not work at all. I'm close to just diabling the device when not absolutely needed ..... BTW I tried Lenovo support and all I got (after several iterations and even when pointing them to this thread) was .... Windows Recovery .... or send to repair station ........
