I've been using Xubuntu Quantal on the same laptop for a year plus and I
no longer have this issue.

Title:
  Lucid - radeon kms causes iwl3945 to drop connection on youtube but
  not with mainline

Status in X.org XServer - ATI gfx chipset driver:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Forgive me if this bug is a duplicate but I didn't see a recent bug
  with these details.... I did a clean install of Kubuntu 10.04 beta 2
  and i noticed the wireless connection would work initially after boot
  and then it would drop and then tray icon would continue to say
  "Connecting" and "Activating" when i right clicked on it and never
  connect again. I did get it to reconnect once after unloading the
  iwl3945 and iwlcore modules and reloading them, then restarting the
  networking init.d script, but that only worked once, every other time
  i had to reboot for it to work again. Most recently though i connected
  it and left it on overnight and it stayed connected fine the whole
  time (i had received IMs meanwhile) and i was able to browse through
  gmail and the web fine but as soon as I went to a YouTube link it
  died right away. So then i installed the mainline kernel version:
  2.6.34-999 from  http://kernel.ubuntu.com/~kernel-
  ppa/mainline/daily/current/ and tried the same YouTube link and
  everything works fine.

  Previous kernel versions I was using that had the problem:
  2.6.32-19
  2.6.32-21

  By the way in case it matters I was using google chrome as the browser and the wireless network I am connected too is using DD-WRT v24-sp1with WPA Personal. My laptop is an IBM Thinkpad T60 and here is my lspci:

   $ lsmod | grep iw
  iwl3945                75395  0
  iwlcore               118803  1 iwl3945
  mac80211              229304  2 iwl3945,iwlcore
  cfg80211              148737  3 iwl3945,iwlcore,mac80211

  So for now it seems to be working fine with the mainline kernel I installed but if there is any other info/testing i can provide let me know.
  Thanks,
