Looking back through the whole 'showlog' log (thanks NiLuJe!), I do see the following:
121007:201249 cvm: I MainView:Information::The device has WAN module so skip popping up the WiFi dialog.
121007:201259 cvm: I LipcService:EventArrived:source=com.lab126.powerd, name=battLevelChanged,arg0=91,arg1=<None>:
At various points in the log, a 10 second delay after the 'skip popping up the WiFi dialog', the next log line is different from one case to the next, the delay seems to be connected to the 'skip popping up the WiFi dialog' line. So there may be something in twobob's theory. Where do I look to find the URL which twobob refers to?
