Public bug reported:
wifi becomes unstable upgrading from ubuntu 12.04 to ubuntu 14.04 for many
users using intel wifi card (as described in thid thread:
http://forum.ubuntu-it.org/viewtopic.php?p=4587552), maybe a driver/kernel
issue.
about every half an hour the connection is lost and I have to reset both pc and
router.
slved via:
sudo modprobe -rv iwl3945
sudo modprobe -v iwl3945 swcrypto=1
cat /etc/hosts
sudo rmmod iwl3945
sudo modprobe iwl3945
Intel signaled a previous problem of compatibility between driver and
some kernels.
I updated recently from ubuntu 12.04 to xubuntu 14.04. the problem
didn't existed when I updated via 'update-manager -d', but appeared when
I reinstalled new xubuntu from live dvd.
