I have actually just posted some input to the bug Bug #67546, which is a duplicate bug of this one.
Ok, I repeat what I posted there:
--------------- snip ------------
I can confirm this bug. I tried to install from the Ubuntu Edgy RC Live CD, but my network card would not get detected. The live cd even froze on me later during installation (during the "Installing software" part).
Ok, I downloaded the RC alternate CD. During the installation procedure, three network interfaces were detected. wifi0, ath0 and eth0. Well, I have only two cards, the Atheros-based Wifi (ath0) card and the Ethernet card (eth0). Selecting either wifi0 or ath0 did not allow me to connect to my network which is completely open. Only eth0 worked. Ok, again the installer chocked during the "software installation" part, put at least I could finish the installation and reboot. I was thrown to the command prompt though. Ok, I manually added the repositories to /etc/apt/sources.list and did a apt-get update followed by apt-get install kubuntu-desktop. I could download everthing via the ethernet connection from the Ubuntu servers. After finishing, I rebootet my computer and everything worked, apart, alas, wifi was and still is not working.
Here is the output of lspci (only the network controllers shown):
00:0a.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
00:0f.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
As you can see, I have the same chip as the original bug reporter of the duplicate bug #67546.

I tried everyting from manually bringing up the network and also by using knetworkmanager. Unfortunately, nothing succeeded.
-------------- snap ------------
I have also installed linux-generic (dpkg -l gives me):
ii linux-restrict 2.6.17.5-11
I rebooted the computer just to be sure. Still, Wifi would not work. Funny is, that I can see my network in the Knetworkmanager popup window, but I cannot connect to it.
