UBUNTU 7.10: WLAN interface problem

Asked by Otto van Lookeren

I started with UBUNTU 7.10 and one problem is left.
I am not able to make a wireless interface with the Broadcom BCM 4312 of my HP Pavilion dv9580ed.
I have downloaded the "firmware for BCM43XX" with the result that the
module was switched on.(LED: red to blue).
With the instruction "sudo lshw -C network" from "Help-- Trouble shooting"
I got the information:

-network
       description: Wireless interface
       product: BCM4312 802.11a/b/g
       vendor: Broadcom Corporation
       physical id: 0
       bus info: pci@0000:03:00.0
       logical name: eth1
       version: 02
       serial: 00:00:00:1a:73:73
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list ethernet
physical wireless
       configuration: broadcast=yes driver=bcm43xx
driverversion=2.6.22-14-generic latency=0 link=no module=bcm43xx
multicast=yes wireless=IEEE 802.11b/g

Compared to a good working wireless interface of another computer where
the "link=yes" is miy link "link=no". To my opinion is that the problem,
because my home wireless network is not found.
Has anybody an idea to let my interface work?

Dear Pedro,
Thanks for your help. The interface is "in use". I am not able to find a wireless network.
The results of troubleshooting are:
*instruction: ~$ iwconfig

lo no wireless extensions.
eth0 no wireless extensions.

eth1 IEEE 802.11b/g ESSID:off/any Nickname:"Broadcom 4311"
          Mode:Managed Frequency=2.472 GHz Access Point: Invalid
          Bit Rate=1 Mb/s Tx-Power=18 dBm
          RTS thr:off Fragment thr:off
          Link Quality=0/100 Signal level=-256 dBm Noise level=-256 dBm
          Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0

*instruction: ~$ sudo iwlist eth1 scan

eth1 No scan results

I did input the SSID with WPA code of my network, but I do not find any network.(there are more in my neighbourhood). The WPA-supplicant has been installed.

Are you able to understand the above mentioned results if I did something wrong?
