Problems with secure wireless network

We are using Acer laptops with wireless cards that connect to our network and in a domain.

Connectivity with no security is fine. But if you enable WEP and try to authenticate to access the network, it fails to get an ip address from DHCP server and fails to authenticate with AD userid to to domain and get no connection. We use a Cisco ACS Radius server. The laptops have Windows XP SP2 using Acer IPN2220 wireless lan cards.

Any ideas?

I have had a similar issue with W2K laptops using a Linksys card and configuration utility and am still researching the issue. Are you using the XP wireless configuration manager or a third party app?

connect them wired at least once. logon to the domain. allow the ad profile to be loaded. log off. disconnect the rj45. then logon on again. it should logon to the pc even though you have the domain selected. it will use the profile you just created by the 1st logon. the wireles util will start an ip will be obtained. it will take about 3 seconds before you have complete access to the domain but should be transparent to the end user. i implemented a wireless lab for a school and they were using travelmate 400 acers. it works fine. good luck.

I have already tried that, I can login ok over a wired network and get an IP address but if I disconnect, and try the wireless, it will say 'Discovering network address' and fails and repeats over and over.

I think the wireless card and/or drivers are somewhat dodgy.
Later, we tried an external pcmcia card and that worked first time!

No, since we are using a Radius server for authentication, we cannot use that (even though its better than WEP).

The same prob i faced in Hawking WAP / Router. I enabled the WEP-PSK and TKIP encryption. Now the communication is secured. Hope this will help.

Problem has been solved. I was given the wrong SSID name for wireless network, the new SSID works just fine!

Thanks for the tips anyway.
