I am using the official release Precise with kernel 3.2.0-23 x64
which i upgraded few days ago from 11.10
upon booting,the wireless connection connects normally but there is no internet/network (i can't even ping the router) connection. I tried to switch off/on the wireless device, i tried disconnecting/connecting from Network manager with no luck.
rmmod iwlwifi and modprobe iwlwifi back again solves the issue.
I'm seeing an error in dmesg:
[ 103.018296] iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000.
attached the dmesg output of the error dump
