Hi everyone[[BR]]
Sorry Im sending this BUG to the wrong place but I didn't find another
place to do it.[[BR]]
Eventually the connectivity is lost and I can't continue working with the
wireless card.[[BR]]
Sometimes is 1h, or 30 min or sometimes more.
[[BR]]
I send you the syslog information about the error:
