Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I recently updated my system from ubuntu 10.10 to 11.04. Since then my computer freezes on startup. I believe my wireless card is the cause. When I turn it off, I can sometimes start without freeze yet this doesn't always work.

Here is the output of "sudo lshw -C network"


  • description: Wireless interface
  • product: Centrino Wireless-N 1000
  • vendor: Intel Corporation
  • physical id: 0
  • bus info: pci@0000:03:00.0
  • logical name: wlan0
  • version: 00
  • serial: 8c:a9:82:25:6e:a6
  • width: 64 bits
  • clock: 33MHz
  • capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
  • configuration: broadcast=yes driver=iwlagn driverversion=2.6.38-8-generic firmware= build 13488 ip= latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn
  • resources: irq:43 memory:c2400000-c2401fff

Does anyone know how to solve this issue?

Thanks a lot in advance for any help! I gladly provide more information if need be.

I believe it's a bug. I experience the same problem (on login) –  Lekensteyn Jun 11 '11 at 16:29
If you have all your files backed up and can afford it, maybe you should scrap your old installation and do a clean install of 11.04. There are a lot differences in the system between each stable release of Ubuntu and something might have gone wrong during the update process for you. –  13east Jul 15 '11 at 6:02
