we have problems with MC7304 cards installed in Panasonic Toughbooks. Since Win10 update 1903, there is the issue with the mobile connection.
After Windows starts, the status of the mobile connection is “Turned off” and the mobile switch button does not react. The name of the operator is displayed correctly and the internet access works. So there is the issue, that Windows says “no internet connection” nevertheless connection works.
The only way to show status correctlly is switch the airplane mode on and than switch it back off. After that the mobile connection get status “Connected” and the mobile switch button begin works. Until next shutdown / restart / sleep.
This issue is present on all commputers with Windows 10 1903+. Before this update, everything worked fine.
All drivers and updates are up to date.
I tried clean installation, but w/o luck.
