Changes

# * These two may have something in common - generally, offline mode sucks:## ** sometimes offline mode doesn't detect disconnection properly, i.e., when used in VMware (or: it detects disconnection, but logon delay still waits full time)## ** on some laptops, WPKG stalls on the first "pre" task. These machines disconnect the network card when running on a battery; however, WPKG hangs even if it's not running on a battery - probably the driver puts the network card in a disconnected state on bootup, and enables it later - this confuses WPKG service.# * some laptops have only wireless connections which is enabled much later. Wait until a network connection is available - what to do with the logon delay then?
