Edimax WiFi Turns Off Automatically

Hello,

I am using Edimax WiFi Adapter. Here i have done all the configuration as given in the following link by adafruit for beagle bone black:

https://learn.adafruit.com/setting-up-wifi-with-beaglebone-black/configuration

Now this script and services run fine on boot up and regular operations.

But most of the time I have a problem where the working WiFi of Beagle Bone Black goes down and Edimax Adapter turns off. Now in order to get WiFi up I have to use following commands to “Ifdown wlan0” and “Ifup wlan0” by connecting BBB to USB or restart the BBB.

I need a very reliable WiFi connection which should never turn off. It should be able to connect router automatically even if the router goes down and comes up after some time.

Here i have disabled HDMI and I am using 5V,2A Adapter.

Regards,
Ajit Wadekar

Something similar we faced earlier with RaspberryPI, and identified that
USB port is not providing enough power to run the WiFi adapter, solved by
using external USB Hub, which been powered separately.

Thanks sunny. Will test that out, but is there any other solution other than external hub?

I used Edimax USB Wi-Fi adapter on Raspberry Pi. I would suggest you to refer to this article. This scheme is good except you need another device to behave as a controller.
