the mystery of atwi

[j. kelley]

Hi.

Recently I acquired a Compaq Evo N610C for free and decided to make the most 
out it by installing FreeBSD. I naturally wanted to take advantage of the USB
wireless card, and found gobs of information on the net refering to Stuart 
Walsh's atwi(4) driver and how it worked only on -CURRENT.I installed, card
was seen as a generic USB device, but it was not seen as a network interface.
More searching turned up many references to atwi, none of which dated past late
2003. Nothing thusfar has worked. I haven't been able to find any documentation
on atwi being implemented into the src tree, I have emailed Stu Walsh but I'm 
sure he's rather busy and as such received no response.  I searched the -mobile
and -usb freebsd mailing list archives with little success, so as a last resort,
I come here.

I hope the least that happens is that someone says, "Silly boy, you've been 
looking in all the wrong places, why don't you just do this..." and I then I
get a little egg on my face and move on. 

Cheers,
john



The device is a Compaq WLAN Multiport W200.

In my kernel config, I have the following enabled. (I added atuwi just for kicks,
since it is the only other wireless NIC USB driver):

# Wireless NIC cards
device          wlan            # 802.11 support
device          atuwi
device          wi              # WaveLAN/Intersil/Symbol 802.11 wireless NICs.
