no wireless connection

Hey all, another post about ' no wireless connection'. I've been reading and trying anything described so far, but I can't connect to my router wirelessly. I'm using Linpus, did base (re)install and didn' t upgrade. Upgrading messes up everything, so I decided to not upgrade untill I got everything to work. My last trial was: switching off any password-stuff to connect to the router (so, no WEP or WPA). This is the output of wlassistant:

I did manage to go wireless online with my pc (Ubuntu) without much trouble (I had to configure the /etc/network/interfaces file manually, but it works like charm - on Linpus, there is no interfaces-file, so I'm lost and I can't find where I have to configure the network). Anyway, the network is unreachable according to the output of wlassistant. What can be the cause of this? Oh yes, I use mac-address filtering on the router, and I accept the MAC-address of eth0 and ath0.
Any help how I can proceed, what I can test or what I can do to make wifi work...? Meanwhile, I will reinstall again, start over (again) with a complete fresh install.

Thanks.

**EDIT1: I see that the driver tries to connect to 192.168.2.1 for an ip-number (dhcp). However, the router has ip 192.168.19.2. It seems to try to connect to the wrong ip-address. How to solve this?

 

Dude thank you for the tips,
Thats great, i'm facing the same problem, so i shall use that command, hofully I may get there
Thanks again
