I have installed Ubuntu 11.04 and I am using Linksys Wireless WUSB54GC Network Adapter.
Now the Problem is, when i am trying to connect wireless network, It trying to authenticate. but it is not connecting. again it is asking password for the network. i re-checked the password. The Password is correct. But i don't know why it is asking password again and again

In my ADSL Router, i have enabled WPA/WPA2 security key.

But if i am connecting with other wireless modem with WEP security, it is working fine

Then why it is not authenticating with WPA/WPA2 Security

I am in trouble. i cannot access internet with my new Ubuntu OS 11.04

I don't know what to do? Please help

    So the network adapter is working fine, but you have an issue with WPA/WPA2 on a particular router.

    Please describe the password - length, use of upper / lower case etc.

    I have experienced problems on a range of devices and routers and OS when the router is set to WPA / WPA2 mode - I get better results with specifiying a single mode eg WPA or WPA2 but not the "either/or" option. I think there is an issue with identifying which to use.

    Do you have a WPA2 only mode, or WPA only ?
