In Ubuntu 8.10, the system detects the card and I can even see signal strengths, but I could never get it to connect to my Dell notebook which also has 802.11N.
Trying Suse, the only trace I can find of it is on the USB bus:
/bin$ lsusb | grep ASUS
Bus 001 Device 004: ID 0b05:1742 ASUSTek Computer, Inc. 802.11n Network Adapter
In yast -> network_devices -> network_settings, it shows both ethernets, but no wifi. I have no module name either to attempt to hack it in.
I looked in the manual and on the specifications page on asus.com and they don't give the chip part number or even the vendor.
Does anybody have wifi working with Suse 64 bit on an Asus p5q3 mobo?
