Wireless network problem

[Golvmopp]

Hello.
I'm not too experienced with this..
I've got a problem on my newly bought Lenovo s10 lap-top. The first thing I did was of course to install Ubuntu.
My problem: The wireless network won't find any of my two routers. The hardware works, it's actually searching when I manually write in the router information. The routers works, my other laptops can find them. Internet works, when I connect it with a wire, it works with eth0.
I've got Ubuntu 10.4

Thank you for helping me out with this.

hi,
your wireless interface runs ok? I mean if you can see other wireless network with network-manager or when you run iwconfig in terminal can you see your interface and scanning with iwlist interface-name scanning?

I can't find any wireless networks.
Didn't really understand what you mean though..

william@S10:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

run iwlist wlan0 scanning
if this show you wireless networks, the problem is with network-manager.

Im sorry if i can not explain correctly but my english is not too good.

From the iwconfig output:
Mode:Managed Access Point: Not-Associated Tx-Power=off
The Tx-Power=off likely means your laptop has a physical switch that turns off the wifi transmitter. Look for the the Wifi switch on the laptop case somewhere and assure it is on.

Thanks to both of you for taking your time.

william@S10:~$ iwlist wlan0 scanning
wlan0 Failed to read scan data : Network is down

The switch is ON.

[JosePF]

"The switch is ON."
The switch buttons on notebooks dont work well on all computers.
I'll try:

1) run:
sudo ifconfig wlan0 up

2) I would check if bios is set to start automatically the wireless interface when boot.

I ran:

sudo ifconfig wlan0 up

Then I had to type in my password and then nothing more happened. Wireless network still does not work.
Everything I could find about wireless network in BIOS is turned on.

Please, could you report:

sudo dmesg | grep wlan0

sudo lspci -k

sudo lsmod
?
