PC configuration PN51T performs well, I run the startup procedure PN51T, all LEDs lit as its user manual. I turn on the tablet settings and wireless networks + + + active WiFi settings + TIM-PN51Te connects to the tablet, but WiFi icon in the toolbar at the bottom right of the tablet is not green and white. I can't surf the Internet. When it is white and green, is it missing the 3G mark?
