One of the first Observatory blog entries that Roman wrote was called Having NWAM under control. It is the only Observatory blog entry that I have printed out so that I can carry it in my laptop bag. I can always refer to blog entries here and elsewhere online, but only if I can first get NWAM to connect. :-)
I recently found another document that is worth printing out in order to have it available if networking problems strike: Troubleshooting Network Problems, which describes how to detect and resolve common problems when using NWAM.
I told Roman about it and he was particularly happy to hear that the document includes information on how turn on NWAM debug logging.
