I've downgraded to the previous firmware and it's working so far (for about 3-4 days in a row). Here is a short howto:
1) download the previous firmware version from http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-4965-ucode-228.57.2.23.tgz 2) rename your actual firmware /lib/firmware/iwlwifi-4965-2.ucode to something else (e.g. /lib/firmware/iwlwifi-4965-2.ucode.copy), just in case ... 3) unpack the tar and copy the firmware iwlwifi-4965-2.ucode into /lib/firmware/iwlwifi-4965-2.ucode 4) restart the wireless module: sudo rmmod iwlagn sudo modprobe iwlagn 5) check that the new firmware has been successfully loaded: dmesg | grep firmware [105935.317633] iwlagn 0000:02:00.0: loaded firmware version 228.57.2.23 Cheers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779159 Title: [regression] after update to 11.04 wireless lan interruptions and Microcode SW error detected.
