Intel 3945ABG won't connect to wireless.

[Nem1976]

I have a Acer Laptop that I'm tring to get connected to my work wireless network. I'm using wicd for my network manager and the laptop sees the wireless ssid but if I try and connect it just sits there saying trying to obtain ip address. I can boot into windows and use the intel card and get connected. If I put a netgear pcmcia card in and I'm able to connect up just fine. I can go home and the intel works fine but just this specific network it doesn't like.

I just can't get the Intel card to connect under ubuntu on this specific network.

Any suggestions would be helpful.

Thanks
Nem

The Intel card is supported natively, so it should be working. Check if the package wpasupplicant is installed.


Also post the output of this command:

lshw -C Network

The access points I'm trying to connect to are a number of Cisco Aironet 350's.

Here is the output of lshw -C Network

Is there any kind of encryption on the network?

No encryption what so ever.

We have an authenticate server that is running radius on it. I have tried to static Ip assignment and I still can't get connected. But if I boot to Vista(dual boot) I can connect with the intel card just fine. This has me completely stumped why this is happening.

The only difference that I see is in the configuration (Dell Inspiron E1505 using 8.04.01 and wicd because Network Manager loses the WPA passphrase) I've got an IP assigned via DHCP:

Ya this is very strange. This wireless works fine at other locations with the intel card it's just doesn't seem to like talking to the cisco equipment when using linux.

try to configure your router with wep with 64bit key
and try to connect because with authenticate server that is running radius sometimes it will not authenticate
