Ubuntu 11.10 crash - Wireless [closed]

Question

I have Ubuntu 11.10 and my system crashes after about 10 minutes. I think it is something to do with my wifi. I have Intel Centrino 6250 AGN + WiMax wireless chipset.

I get the following error on the screen: Error sending POWER_TABLE_CMD: time out after 500ms and a big list of other status messages together with it.

I don't know how to gather the messages printed on the screen when the computer crashes. I am new to Ubuntu and not very familiar with the terminal commands.

Any help would be much appreciated.

Thanks Harish

If my comment works for you, create the file /etc/NetworkManager/dispatcher.d/90wirelessfix.sh and add this to the contents:

#!/bin/bash   
IF=$1
STATUS=$2

if [ "$IF" == "wlan0" ]
then
    if [ "$2" == "up" ]
    then
        iwlist wlan0 power off
    fi
fi
