WiFi install problem

by rdiederich on Tue Feb 19, 2013 11:29 pm

While trying to install the updates for the USB WiFi. I encountered to following error. It appeared that all the firmware installed correctly but when I did a reboot prior to running "ifconfig wlan0" as per the instructions I received the errors listed below. I have attempted the total install/upgrade multiple times and get the same error.

Can anyone please provide me an approach to resolve this problem?

Thanks

That's the watchdog timer refusing to close. The driver has been compiled with an option to prevent it from accepting close requests (see line 182). Have you done anything special with the watchdog?

Thanks for the reply,

I have not changed any code. I was following the instructions on page 16 of the http://learn.adafruit.com/beaglebone document which installs the linux-firmware-rtl8192-cu code which I believe is the code that enables the usb wifi adapter. I have tried re running the instruction at least 3 time with the same results. I will try again today and see what else I can fine and port the results.
