I have problems with my wireless card in the thinkpad x201. Everything is working fine - wireless connects and i can hit up websites. But after sleep/some time or changing the wireless AP form one to another something breaks.

lspci -vvv:

The only fix so far is a reboot of the whole system. I used a few distros over the last month like gentoo,arch,debian and it happens on all of the distros. It never happend on the Windows 7 system that is installed too.

I hope someone can help me with this.


I had nightmares with Intel wifi until I ran across this. Perhaps it helps. Had to turn off power-management

Reference: How can I prevent iwconfig power management from being turned on?

Create /etc/network/if-up.d/wifi-powerman-off (chmod +x)

# Reference: https://askubuntu.com/questions/85214/how-can-i-prevent-iwconfig-power-management-from-being-turned-on
WLAN_IFACE=<<interface name>>
if [ ! -x $IWCONFIG ]; then
    exit 1
if [ "$IFACE" = $WLAN_IFACE ]; then
    $IWCONFIG $IFACE power off
