Sierra Wireless EM7345 4G LTE had event Fatal error: The miniport has detected an internal error.

Hi ,

 

I have updated to the 1607 Anniversary Update in August and noticed that my WWAN Sierra Wireless EM7345 had problems starting up after reboot. Because of other problems with the 1607 I reverted back to 1511 and everything was alright again.

A week ago I upgraded again to 1607 and again, my WWAN sometimes cannot start when booting up. The error log shows Miniport Sierra Wireless EM7345 4G LTE, {b343453c-24e6-493d-ba47-33eaec4de5e3}, had event Fatal error: The miniport has detected an internal error (details see below). So this clearly has to do something with the 1607 update or the drivers for the WWAN. I am using the latest drivers from the Lenovo website and have also tried to update drivers in device manager. But no luck.

 

What helps to finally start the WWAN is either a reboot (the chances the WWAN is started properly are about fifty-fifty) or clicking WWAN off and on in flight mode options of Windows.

 

 

Maybe someone has an idea other than waiting for Microsoft to fix this stupid 1607?

 

Thanks and best regards,

Martin

It is restarting and not answering within 400ms window when resuming from sleep. Probably all users have this event logged (one time after resume), at least I have too - however my card is resuming without problem every time, just a few seconds delay.

So I am in this thread not because of problem but log content. I understand card is connecting to network and it takes a few seconds. However I think also phones are quicker to search and connect so question is if is it normal? Does someone have EM7455 resuming from sleep instantly (or nearly instantly)?

Of course it could also depend on network conditions, number of network providers and so on however for modern chipset shouln't it be nearly immediately?
