Im using my n900 very often as 3g modem. Im using mobile hotspot app and my ping is very good for 3g modem 80-200ms. It should be better with usb cable because wlan isnt affecting between connection. Or should it ? Im using pc suite to connect n900 with usb and then connect OTA. With usb + pc suite my ping is every time over 300ms. Why is that ? With my thinking it should be lower with usb than over wlan ? Any ideas ?
