It appears that leaving a ping session running with an interval of ten seconds somehow suppresses the network connection drop and wpa_cli chatter. There's a steady stream of "group rekeying" messages, but nothing suggesting an error and the link stays up. Could there be an inactivity timeout that's getting into trouble? Certainly not a fix, but useful as a workaround for now. If this suggests any further experiments I'd be glad to try them. Thanks for reading, bob prohaskahome | help
