BSOD USB 3G modem + VPN

I am getting BSOD every time I try to start a VPN connection while connected with a USB 3G modem.

The modem is Huawei e173. Initially I was having problems only with the Cisco VPN client, which would connect but crash with BSOD when any data transfer started, but now I am also having problems with SonicWall VPN Client. The dump files attached are from a SonicWall crash - BSOD as soon as the client even starts initializing the connection.

Dump files attached per BSOD sticky. I was not able to run perfmon /report - it never finished despite waiting for quite a while.

Any help with this is much appreciated!

Device Concerns:

Cisco Systems VPN Adapter for 64-bit Windows	ROOT\NET\0000	This device is disabled.
SonicWALL Virtual NIC	ROOT\SWVNIC\0000	This device is disabled.
Shrew Soft Virtual Adapter	ROOT\VNET\0000	This device is disabled.

Were you aware of the above? If so, please explain your reasoning so we may understand your troubleshooting steps. I assume it has to do with the VPN problems you've had?​

Software Concerns:

Your VPN software is still running even though the VPN devices are disabled. This may cause conflicts. Also, if you try to use one VPN manufacturer, you should remove the software and devices from the other manufacturer.​

Analysis:

Drivers:

Your SonicWall VPN drivers are out of date. This may cause conflicts.​

Blue Screens:

Crashes point to your USB NDIS Miniport Driver from company Huawei Technologies Co., Ltd.; Either replace the device or update its driver. You may need to contact Huawei Technologies for support information: Support - Huawei Device Co., Ltd..


The following information may be helpful if you need to re-install/update the driver for the USB NDIS Miniport device.

Thanks for the quick response.

I have not been able to find any updated drivers for the Huawei modem - and suspect that this may be the main cause of the problems I'm having.

I did find that removing and then reinstalling the Huawei drivers fixed the SonicWall VPN connection. This is now working normally again (so long as I don't even start the Cisco service).

I have not been able to get the Cisco VPN to work at all - BSOD every time - but I think I'm going to give up on that for now. It works fine with a regular wifi connection, but not with the Huawei modem, again pointing to the modem driver as the source of the problem. This will have to wait until I can get updated software for the modem.

As far as the VPN clients are concerned I realize that the network devices are disabled - this is normal, they are enabled by the VPN client software when a connection is initalized. With the exception of the Huawei device, I have not had any problems having all of these VPN devices installed concurrently.
