I have an hp 6315. I have had most of these problems over the years. I can get my WiFi to connect but only at 3 feet from WiFi Router, and at that range i only get 1 bar on strength. I do this on or off wall power not in cradle. I believe my WiFi internal antenna is not connected properly. Any one has any ideas on checking for disconnected WiFi antenna on an hp Ipaq 6315
