New user here.
We are experiencing problems with the new L series with WWAN (Fibocom L830-EB) when it connects to Cicso AnyConnect.
I've spent many hours twisting my head to figure out what is wrong.
I have attached some pingtest so you can see what happens.
I have two troubleshooting scenarios.
L580 running Windows 10 Pro 1709
Microsoft approved driver 10.0.16299.98
Fibocom Sensor driver 3.17134.0.6
L580 running Windows 10 Pro 1803
Microsoft approved driver 10.0.17134.1
Fibocom Sensor driver 18.104.22.168
What I have tried:
Installing Microsoft driver 10.0.16299.98 on the 1803 (rollback driver) didn't work. (Which I thought would have been a solution, since it works with VPN on 1709)
Updating Firmware (L830-EB_FWUpdateTool_18300.1002.00.01.01.14_signed)
Uinstalling Antivirus (Symantec)
Install latest Fibocom driver
I am out of ideas at this point.

Same trouble here, with Windows 10 v1803 and L830-EB (drivers 3.17763.1034.1) when VPN is up (Pulse Secure 5.2).
Have you been able to fix it or to find a workaround ?
We will try to update Windows 10 from 1803 to 1809 in order to see if the problem remains.
Thank you for your help

We found slight inprovements when disabling IPv6 on the interface of Fibocom, but could not see a pattern that this could be a solix fix.
Also we got improvements when disabling Cisco Web Security but that wasn't a good solution either.
We are now in the process of rolling out Fortigate VPN to all our users via Azure Intune.
Which has solved our problem.
Be carefull when updating to 1809 we got worse connection with cellular data than before, even the interface disabled itself.
