Hi, I have a laptop DELL M90 with an Intel PRO/Wireless 3945ABG card. I'm using centOS 5.1 kernel 2.6.18-53 i386. I installed ndiswrapper v 1.52 I installed the driver http://ftp.us.dell.com/network/R164255.EXE The wireless-tools is v 28.2 When I trying to connect to my wireless access point with encryption key disabled everything work fine !!!! When I enabled the encryption key on my wireless access point with à 128b WEP it's impossible to connect to it. If I need to connect to the same wifi access with an ancryption key (WEP 128b) it's impossible :-( I receved the message that the laptop cannot get an IP Adress. The same laptop under Windows can connect to the same wireless acces point with encryption key enable ou disable (WEP 128b) The result when Encryption key is off and the laptop is connect.
