At least you are taking the time to read the available docs, which is much more than most users do :-)

All that points are basically summarized to: how to setup a capture and analyze the results

That's exactly what I was thinking about the part missing in the User's Guide. Thanks for your examples anyway.

That's basically used as a "database for capture files" so one can look at those packets if none of such available is on your own network.

It gave me a good idea what a user misses from the user's guide, so yes, it was helpful and much more feedback than I usually get ;-)

Having a general network troubleshooting guide using Wireshark would be really helpful, but that will require a lot more work than I currently have the time for :-( 

However, long cold nights at winter time are coming, so we'll see what the future will bring ...
