Thanks again!
As expected, the browser on a phone or a tablet cannot connect to the content server without safe mode but the two machines do recognize each other (they accept each other's pings, for example). Compatibility issues between Calibre / CC and McAfee / Windows seem most likely. However, there are a lot of knobs in the McAfee / Windows combination, and I have tried many different combinations. Calibre / CC seem to be the only pair of programs I have encountered so far with such issues; iTunes file transfer, for example, works fine in wireless mode.
