Do i need more power to run my pi

Fri Oct 06, 2017 10:39 pm

Hi, I am using a pi 2 with usb pidrive, usb wifi dongle and a camera module. I am using the standard power supply 5v 2.5 A. I am losing connection and sometimes the recorded video is in slow-mo the first time it is played. I have noticed the wifi has a weak signal on the pi. My wifi score is around 65 for 2.4ghz. I was wondering if I should be using a 5v 3a and or a powered hub.

Does the red PWR LED go out when the Pi misbehaves? Do you get a lightening bolt icon on the screen? If neither, then power is probably OK and the problem is elsewhere.

Thanx for that advise, i did not know that. My power supply seems to be ok, I am wondering if it is the drive. I will look up the commands I need to use.
