Trying to figure out what is causing the my dell mini random 3G disconnection , I disabled some drivers in Device Manager and found that the all functions of the WWAN and GPS still working normally even with the following drivers disabled and even after rebooting:
Dell Wireless Mobile Broadband MiniCard HSPA PC SC Port
Dell Wireless Mobile Broadband MiniCard HSPA Modem
Then, for what these drivers are ?
Dell Inspiron mini10 , 1Gb, Windows XP, 3G HSPA 5530 WLAN Minicard , Bluetooth, Wireless 1397, Intel Graphics 500, 6 cell battery.
