Sony VAIO vgn-n325e + Ubuntu 11.04 + wireless issue

[lewis866]

hey guys , im pretty new with Ubuntu and having a issue with my wifi. I have the network icon in the upper bar but cant see any network in it. It used to work well when I was still using vista. And with my other computer I see a shitload of wireless network available ( using vista ).

I did the basic command in the terminal and it look fine. ( ifconfig and sudo lhsw -C network. )

Anyone can help ?

Lewis.

Everything is looking good.
Execute this command:

iwlist wlan0 scan

Post all output.

[lewis866]

louis-denis@Pc-Lewis:~$ iwlist wlan0 scan
wlan0 No scan results

louis-denis@Pc-Lewis:~$


But I know there is other network around, I see them with my other PC.

[jayd512]

This should be working.
Is Ubuntu the only OS on this laptop?

[lewis866]

Yes it is. I just realize that when I boot the computer for the first time after a while I can see all the wireless available and connect for 1-2minutes and then I loose the connection and cant see wireless no more. But few day ago when I was still Vista user everything was allright so I guest the hardware is ok ...

Have any idea ?

thank.
