Wi-Fi problems with Kubuntu

[AxessTerminated]

the setup:
Thinkpad T20 PIII
DLINK DWL G630 wifi card

the newest Kubuntu release recognizes my card fine. i've searched Google for hours, and can't get connected to my network

i can iwlist wlan0 scan, and see all the info, and i use iwconfig to set it all...except KWifiManager reports all 0's for my AP. When I try setting the APs IP address, I get an error telling me that wlan0 doesn't support IP addresses.

What's going on here?

Oh yea, when I try dhcient it goes through a bunch of garbage and eventually tells me that there are no leases...and it sleeps.

Also "iwlist wlan0 scan" returns the AP's MAC address, as well as all the other correct information.

The only peculiar thing I noticed was that my 40-bit WEP key is 6695481890, but it shows it as 0669548189, I don't know if that leading 0 makes a difference.

I also tried copying the resolv.conf file over from Knoppix, but it didn't make a difference.

No clue. I assume you are using WEP, and not WPA or .11i. If you ARE using WPA or .11i, you'll probably need a WPA supplicant package.

I'm not certain. I don't use Kubuntu, just Ubuntu. I don't use it on a platform with a D-Link either.

I am certain you will find a lot more information at http://www.ubuntuforums.org, rather than here. Good luck.

Kubuntu and Ubuntu are the same distros...except Kubuntu uses KDE since Gnome sucks :P...But what configuration files would be involved, other than resolv.conf? I have no rc.conf either..which is something I had to set up when I tried Gentoo...

I know what kubuntu is. It's the repackaging of a fine distro with KDE as the default instead of Gnome. I have no idea why you'd use that, unless you didn't want to bother instaling Ubuntu and then using apt-get to install KDE. *shrug*

As for which config files. I have no clue. I use the Gnome network settings, and it works just fine for me. The Ubuntu forums is possibly teeming with help...or at least links to Kubuntu resources.

Found this as well: http://kubuntuforums.net/

Best of luck, and let us know what was happening, once you've resolved it. I'm curious!

Well I've joined some other forums, posted, and now I'm waiting for help *sob*. But just in case someone can help, here's what I did after booting, and opened a root shell:

Hmmm. Well, you can't run Konqueror bekause you haven't given r00t permission to draw to your display. You've used this device and laptop with different OS/versions successfully in the past?

How about turning off encryption for the AP and trying the good old fashioned way? Sure the right driver is in there?

[AxessTerminated]

I've tried turning off the encryption today too...but to no avail. And yes, I've used three other distros with the wifi card, and they gave me no problems. Actually...just Knoppix and 2 flavors of it; ClusterKnoppix, and Knoppix-STD. I just use ndiswrapper, wlcardconfig, then netcardconfig, and I'm online.

How do I allow root access to x11?

what else I've noticed is that dhclient tries to get an IP from 255.255255.255 on port 67...shouldn't it be trying to get one from 172.16.0.1...i dunno what port though.

I can't use "route add default gw 172.16.0.1", it tells me that the network is unreachable.

A_T

edit: "dhclient -s 172.16.0.1 wlan0" doesnt work.

[AxessTerminated]

Okay, my card is a DWL-G630 rev C...which maybe isn't supported or something. So no I'm trying ndiswrapper...but some other module has got to be using my wifi card in order for it to work as well as it did (even though it wasn't that well)

How can I find out what module it is?
