NPCAP - Breaks connection over mobile net adapter (DW5811a Snapdragon X7 LTE) #1651
After installing Wireshark with NPCAP 0.992 on Windows 10, my mobile network adapater no longer has internet access.
Interestingly, it gets an IP, it sets up routes, but you cannot ping even the other side of the tunnel. Ping returns a General failure.
Removing NPCAP and restarting the computer fixes it.
Unchecking NPCAP in the connection properties of the adapter has no affect, a full uninstall needs to happen.
What diagnostics would be usefull here?
Thanks for the report! We're tracking a similar problem with a Sierra Wireless mobile adapter over at #1497, and we've gotten a report on Twitter as well. In that case, reinstalling Npcap without the loopback adapter was sufficient to solve the problem. Does this solve it for you as well?
We are investigating alternative methods of providing loopback capture and injection support that do not involve an adapter, since this has been a source of many problems. In the case of mobile adapters, I believe it has to do with routing metrics, but manually setting high metrics for the Npcap Loopback Adapter does not fix the issue; Windows may be doing something "smart" to prefer non-metered connections.
Diags are attached.
The work around does not work, if you just go into the Mobile Adapter Properties and uncheck either or both NCAP drivers the failure still exists. If you disable the NPCAP Loopback adapter it will work.
Let me know if there is anything else I can do to help you further.
