Hi,

Welcome to LQ!

Not enough information to help you solve the issue. Please consider reading the following;

Quote:

FYI: I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem or query.

How do you know the wireless is connected and to what? Whats does 'ifconfig & ifconfig -a' show from the cli?

What about 'route -n' and the contents of your '/etc/resolv.conf' file from cli?

You could look at Ubuntu Wireless Setup or HOWTO: Set up wireless internet (Desktop or laptop)

well when i press that little wireless symbol on the task bar and press "Namai", which is the name of my home wifi network, in the dropdown menu after a few seconds he asks me for a password, then i enter it and after some time a message appears that i am connected to a network "Namai".
