On the website of raspberry pi 2 I read that the current draw for usb ports can be switched from 600mA to 1.2A. I searched around and I couldn't find anything that shows how to do that, I went to raspi-config but there's nothing there about power. What should I do?!

A friend suggested that power might be a problem because every time I connect a local router to my raspbian while I need to be connected to the internet over wifi my raspberry goes nuts and hangs and damages the SD card, and I have to do re-imaging again.

Also, my samsung charger has output of 9v-1.67A or 5v-2A together. Does that mean that it can manage the maximum rate? It is a fast adaptive charger.

I think you're looking for max_usb_current=1 in /boot/config.txt. There's a discussion on setting this on the RPi forums that covers power supply considerations.
