I'm beginning to wonder what role an Internet connection plays in getting the initial fix. I've installed and run agps some weeks ago. Just now my N810 was in off line mode and I started Maemo Mapper. It found no satellites so I reset the GPS by disabling and then enabling. Still no satellites. Next I put the tablet in online mode and established a WiFi connection. Again I reset the GPS and now I have satellites in view and acquired a fix within a minute or two. Is this a coincidence or have I discovered a solution? More experimentation is in order. Comments anyone.
