I am indeed a newbie so bear with my stupidity. I am setting up my third computer with Ubuntu/Kubuntu and have come across a problem with this Acer that I haven't been able to resolve. I think that I know what it wrong, I just can't figure out how to fix it.
The problem is that the wireless just stopped working on this laptop after a couple of hours of use. It may be that the wireless disable switch was hit by accident and then turned back on. Regardless of the cause, my wireless does not work any longer. I have the option via the network manager to setup a wireless connection but it is not seeing my wireless network when I scan. I updated the network driver to the madwifi drivers as suggested and had some success. When I run iwconfig It appears that my wireless card (ath0) is working, but the network settings when I run lshw -c network show my wireless network using wifi0. I am positive that this is probably my issue but I can't seem to figure out how to change the lshw result. I tried to change the /etc/udev/70-persistent-net.rules line for ath0 to wifi0 but it simply added the ath0 line back in once I rebooted. I didn't expect that to work but I am getting deperate. Below is the text of both an iwconfig and lshw -c network run in my terminal.

Thank you in advance for any assistance in this problem. Just as a side note, I found that all three of my computers have no network information in the /etc/network/interfaces documentation. Itonly have the loopback lines. I have added ath0 to this configuration with no positive result.
Thanks again.
