BBB - wifi locking up board

Post by jayfehr »

Hello, I'm trying to get a wifi dongle working on my BBB, and every time I boot with wifi enabled the board slows down almost to a halt. I'm using the most recent version of the official debian build (3-27-14-flasher) and here are the results of "uname -a":

Code: Select all

Linux beaglebone 3.8.13-bone43 #1 SMP Wed Mar 26 14:21:39 UTC 2014 armv7l GNU/Linux
I've tried two separate dongles, both with have the same issues. The two I have tried are:

This install is barely modified. Since flashing the eMMC all I have done is to change the root password. Create a new user account with sudo access (which is what I'm currently logged in with). And of course, enabled wifi by uncommenting the following lines in /etc/network/interfaces

Code: Select all

auto wlan0
iface wlan0 inet dhcp
    wpa-ssid "essid"
    wpa-psk  "password"
Of course I changed the ssid and password to match my setup.

Once I reboot my board I am able to ssh into the BBB through the wifi dongle. However after a minute or two the board comes near to a standstill. Typing in commands is delayed for about 30 seconds. They do eventually appear, and in batches so they are being cached at some point. Pinging Google also works, but very slowly and with about an 80% packet loss.

Thinking the issue may be due to not enough power from the USB connection I switched over to a 5V 2A power supply (linked below) and am still having the same issues:

Any help with this would be appreciated. Thanks,

Jason

Try running `top` from the login shell and see if that shows any process consuming more resources than it should.
