Problem: madwifi is buggy with this wireless chip. If using 32-bit, ndiswrapper is possible and far more stable.

lspci:
03:00.0 Network controller: Atheros Communications, Inc. AR5418 802.11a/b/g/n Wireless PCI Express Adapter (rev 01)

Solution: (Kubuntu 7.10, YMMV)
wget ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/7iwc28ww.exe
sudo apt-get install cabextract ndiswrapper-utils-1.9
cabextract 7iwc28ww.exe
sudo ndiswrapper -i WINXP_2K/NET5416.INF
sudo modprobe ndiswrapper
echo ndiswrapper |sudo tee -a /etc/modules
