Perhaps I'm not the only one who doesn't know what Wap has to do with
Linux?

Hmm. Using ndiswrapper, under linux to access a wireless access point
and setting up network to work thus, I hope is related to linux :-) I
suppose I could have said wifi instead of wap.

People put off by the Subject won't get to see the article, no matter how
'on topic' it might be ;))

I'm guessing you mean that you can't get your USB wifi dongle to
work with WPA encryption - perhaps putting /that/ into your Subject would
get more interest?

Ok. I meant Wireless access point. I have the same access point which I
can access through my laptop also runing crux.

So you didn't want to discuss web access phones ...

I've changed the Subject to something closer to what your difficulty seems
to be ;))

I've done some trimming to highlight the points that I think might be
significant, although I'm no wifi expert (and I've never used Crux).

iwlist shows my wap as below.

Is your router set up to permit access from the MAC number identifying
your wifi dongle? Do the DHCP settings on the computer and the router
agree? Does the dongle handle 802.11b as apparently required by the
router you've found by scanning? Is the dongle tuned to "channel 1"?


I don't use dhcp.

So your router and your computer have to agree about what the IP number
for the computer is.

The access point is set to accept any mac. The dongle
is 802.11g and backwardly compatible. How do I set the dongle to channel
1? I tried iwconfig wlan0 channel 1 but it does not change anything when
I try to read back the outcome by doing iwconfig wlan0!!

Thanks

I would expect to see the encryption key shown (in Hex) as part of the
output of iwconfig for your computer's wireless device (as the router
seems to have encryption "on"), rather than the "off" you have, as well as
the ESSID specific to your router, and Mode:Managed rather than Auto.

I don't know how to make your USB dongle change from 802.11g to the
802.11b which your router requires, nor how to make it use 'channel 1';
those may be 'driver' matters specific to your particular hardware.
