Roxxor2 · 03-19-2006, 03:59 AM

My computer (network card) detects the network but it does not connect to it. I have typed the correct WEP key.I am running Ubuntu.
Our router is set to:
- Channel 1
- Open System
- Ascii
- 64 bit encryption

sudo dhclient wlan0

Code:

roxxor@laptop:~$ sudo dhclient wlan0

I have done everything I know.

Please help me!

In my experience sometimes an interface needs to associated with an access point before communication can take place.

iwconfig wlan0 ap xx:xx:xx:xx:xx:xx

you did issue these command didn't you?

modprobe ndiswrapper

dhcpcd wlan0 or dhclient wlan0 or pump -i (wlan0)? not sure about this last one

sometimes you need to issue encryption open or restricted

example:

iwconfig wlan0 key open xxxxxxxxxxx

or

iwconfig wlan0 key restricted xxxxxxxxxxxxxx

Holy shit!!!

I just typed iwconfig wlan0 ap 00:00:00:00:00:00 and then it worked!

How come?

DrEwMoNeY · 03-19-2006, 04:26 AM

Try iwconfig again to see if anything changed. Did you literally type all zeros did you put the ap address in.

Yes I did, but now I think it was
iwconfig wlan0 key open <my passwd> that helped me.

As long as it works, that's all that matters, right?

I've used a couple different cards and routers with ndiswrapper, they all react a little different than the other. Sometimes it's just trial and error.

Needless to say, I've spent a bit of time at the ndiswrapper wiki. Still learning myself, though.
