I have setup my new Pi2 to run with ethernet. Then I connected my edimax wifi dongle (which works well with older pi's) on one of the usb ports. After a couple of minutes, the ethernet interface of the pi2 goes down and the wifi interface also is inaccessible.
I read in some forums that this may indicate a power supply problem. Although the supply I used is 5V 2A, I changed it with another one but with no success. The kernel I use is 3.18.10-v7+ #774 SMP PREEMPT Wed Mar 25 14:10:30 GMT 2015 armv7l GNU/Linux.
Any ideas what to do next??
