iwlist scanning sees the network; dhclient can't connect (iwl3945 nor ndiswrapper)
 
1. I can load the module: iwl3945
2. I can use iwlist scanning to see my wireless router
3. dhclient and network manager don't want to connect to the wireless router


update:

I tried the ndiswrapper route, and that did not work either. I used the XP/2000 32-bit drivers. So, something unusual is occuring.

Operating system: Debian Lenny via dist-upgrade
Kernel version: 2.6.25-2-686
Computer: Gateway T-6838

I have this new laptop I'm finger tapping, and I've been trying to get it to work with wireless. Supposedly it was yapping about firmware and the such, so I found some website that told me to install firmware.

website: http://fobiazone.wordpress.com/2008/05/12/debian-lenny/
Code:
apt-get install firmware-iwlwifi
That's the only thing I did from that site, because trying to manually install the newer firmware gave me make errors.

That helped a little, I guess. I previously had the module blacklisted cause it kept yapping while I was using the ttys. And when using w3m and having lines of text interfere... it's not cool.

here's what i've been up to...

universe:/home/workstation# modprobe iwl3945


NOTICE:

I also obtain the following information when using ndiswrapper instead of iwl3945.

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
That is the story.
Network manager, too, can see the network but can't connect.

I don't know what's going on.

You haven't specified which station to connect to, you've only scanned to see what's around. Doing it from the command line, you'd do something like
Code:
iwconfig wlan0 mode managed essid fastermangrate-on-song channel 11
Assuming there's no encryption, that should probably associate with the AP. Then you can try dhclient again.

That did not work.

I figured it would not, because I think dhclient wlan0 pretty much says grab an access point and try to connect to it, thus me not needing to use iwconfig.

This is weird.
