wireless internet connection

[Guest]

Hi,
I have installed Kubuntu on IBM think pad. It was connecting to internet via wireless before upgrade. But once I upgraded to latest KDE, it could not make wireless connection.

Re: wireless internet connection

What version of Kubntu? What version of KDE?

What does your /etc/network/interfaces file contain?

Re: wireless internet connection

It looks like your wireless is being recognized.

Does

iwlist scanning

show yours and any other wireless points in the vicinity?
