Does anyone know of any patched libertas drivers or 8688 firmware?
I can certainly confirm that the Guruplug will not work for very long as a WiFi client with the factory distribution. I have also tried recompliling using the sources published with no difference.
I created a really simple script. I have two Guruplugs and the same happens on both. When I run this on a Guruplug connected ONLY via wifi to my home router, the Guruplug crashes - typically after 1 - 2 minutes. There is no error when using ethernet of course!
#!/bin/sh
while [ 1 ]
do
wget ftp://192.168.1.101/Downloads/datasheet.pdf
rm datasheet.pdf
echo "done"
done
exit 0
The same error occurs when using curl to download instead of wget (so it is not the wget package), but it works when I copy the file from one directory to another (ie eliminating the wifi element of the test).
This is the failure I see

If I then take wlan0 down and plug an ethernet cable in and re-run the test, it will execute happily in its loop until I stop it.
Does anyone have the guruplug working in wifi client mode?
