Lenovo L470 - EM7455 4G LTE Mobile Broadband

Hi all,

i have a problem with my Lenovo L470.

I would like to connect to internet with a sim card but i don't see Sierra Wireless EM7455 device on my Network Adapters.

i tried to install it but when i tried i saw that Driver result already installed on my PC.. but i can't see device..

I saw on BIOS setup and WWAN is enabled...

What i can do?

 

Thanks to all

Welcome to the Community

Are you sure the wwan card is installed in the laptop? Are there unknown devices in Device Manager (Other Devices category or anywhere)? What're the laptop's MTM code and OS installed?

Running newest bios and drivers, according to Lenovo

The answer (and a cause of issue) is the same as described below

Marketing p/n 4XC0L59128 matches FRU 00JT542.

You should REALLY not use model name EM7455 on different modems. If the modem is different then use another model name, FRU and product numbers.
