CF-31-5 with windows 11 pro em7355 wwan issues

So Panasonic tech support is saying that they don’t have drivers for anything after windows 10 version 18 09 and the wwan card manufacturer doesn’t list a driver for anything after windows 10… any options out there??

You should be able to use the Win10 drivers in Win11

Ok I’ll try it out and see what happens… is there a utility I need to make the connection once the drivers are installed??

That should be included with the software package, at least with the usb modems that I've used in the past. I've yet to install a Sierra Wireless card into my toughbook so I don't have any experience with that particular modem.

Well installed the drivers from Panasonic and the port_install but no luck… I don’t even see the wwan in the bios to enable it so I’m not sure really where to go and there are no videos on 11 pro for the 31’s…

If that doesn't work, ive been using this program on my cf 31 mk5 with windows 7 32bit, windows 7 64bit and windows 10: https://sdi-tool.org/

Get it on a large (120gb) usb and bring it to all your computers to update all the drivers, pretty slick.. all the panasonic utilities and function buttons work. 10/10 super easy highly recommend.
