Ndiswrapper And Wpa In Suse 9.1

Fri Oct 8 01:41:18 PDT 2004

Hi,

in SuSE Linux 9.1 Pro I got my Centrino Broadcom Crad running with 
ndiswrapper (0.10). Authentification works fine with WEP, now I would 
like to use WPA.

Following the den instructions found in the ndiswrapper wiki I have 
installed wpa_suppicant (0.25). This seems to start correctly and also 
seems to communicate with the router. Authentification does not seem to 
be the problem. BUT: WPA and network configuration cannot cooperate. 
Only in one out of 10 cases an IP can be gained from the DHCP server 
(see below). But even then the route is incorrect, there is no 
connection possible. In most cases the computer does not get any IP from 
the DHCP-server.

- Does anyone know how ifcfg-wlan0 and WPA-configuration have to look 
like, so that WPA is recognized by the network configuration for 
authentification?
- What is the correct order (and how? ifup, dhcpcd?) do wlan0 and 
wpa_supplicant have to be started?
- And: Where would one integrate wpa_supplicant to automatically start 
in SuSE?

Thanks for any suggestions,,

Arne
