I am using Ubuntu 9.10

Type in "top" in the terminal and post what it says.

It will tell what program is using so much of your CPU resources.

You may want to try Xubuntu if the machine is way to sluggish.

I find that KDE or Gnome are way to hefty for my machine.

Hi -

Please:
1. Look at these links:
http://ubuntuforums.org/showthread.php?p=7479544
https://bugzilla.redhat.com/show_bug.cgi?id=506659

2. If you have an Atheros wifi card (e.g. ath5k), try disabling it and see if the problem goes away
<= EXAMPLES: dmesg|grep -i ath

3. Failing all else, look at Athero's latest/greatest drivers page:
http://madwifi-project.org/

'Hope that helps .. PSM

PS:
Please DO post back as to whether or not Atheros wifi was actually the problem!

I think you'll find this marked solved in another (at least one) thread.
Multiple posts about the same problem ...

As syg00 said - this is a duplicate post.

The OP solved the problem by removing his "wireless NIC".

So it sounds like it was probably an Atheros NIC, and probably the same as the issues cited above:

Also, for future reference, it's extremely likely there might be a solution here:
