When I install Ubuntu 9.04 the wireless works fine on my Toshiba Satellite. However, when I let the update manager update to the newest things the wireless doesn't even show up as a choice, as if the wireless card isn't installed. The drop down menu from the network icon only has wired on the list and I can't seem to find anywhere to set the wireless as existing. The same thing happens when I install a new version of Ubuntu 9.10. It just doesn't seem to be there. If anyone knows why this is or how I can fix it it would be greatly appreciated. If you need any more info from me just let me know. Thanks!

I had the same problem with Ubuntu 9.10. After installing 9.10 my wireless was not visible in network-manager. Even trying to get my wireless going from the terminal was having limited success.
What I did was to install wicd. After I installed wicd my wireless showed up right away and I was quickly online. You may need to reboot to have wicd automatically load up your wireless. I don't remember if I had to reboot or not.
Note that installing wicd will remove network-manager.
If at some point you should ever wish to uninstall wicd and want to go back to network-manager, then just reinstall network-manager and network-manager-gnome.

Unfortunately wicd has the same problem. Any other ideas?

Verify that Ubuntu still is detecting you wireless card. Run lspci in the terminal and see if your wirelss card is listed in the output. Then run lsmod to verify that the proper driver is being loaded. If the wireless is detected and the driver loaded then wicd should be able to detect and configure it for you.
