How can I share my files from mobile device to PC through wireless router? I have a wireless router and my pc has ip : 192.168.1.101 and my htc desire mobile has ip: 192.168.1.102. But I am not able to ping my mobile from PC. I just want to access my files on mobile through pc. I have also downloaded some app from PlayStore but I am not able to ping my mobile though my pc and mobile are both on same network. Please ! help.
Your version of Android may not have a ping service as one of it's utilities, so trying to ping your device might not work.  Regardless, you should be able to navigate directly to your device's storage from your PC's file manager by running an Android app like Samba.
