What does 'sudo iwconfig' show? If it reports 'no wireless extensions' found then you have a driver, firmware type of problem.
|
lo no wireless extensions.
eth0 no wireless extensions. wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off |
The wireless card is called 'wlan0'. You are not associated with an access point. What have you done to configure the wireless interface?
Could you run the command 'sudo iwlist scan' and post the results? Please start using the editing icons to post the output. It keeps things lined up, and avoids the smiley faces. On Quick reply the right most icon inserts quotes, you paste the output between them. |
'sudo iwlist scan'
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning. wlan0 Interface doesn't support scanning : Network is down |
My wireless working properly on another PC.

What do you mean: to configure the wireless interface?
|
This is Ubuntu, correct? If yes, it comes with Network Manager installed. Did you go in there, and configure ESSID, IP address from DHCP or a static address? DNS addresses?
If you have not configured it, that is square one, after you have the correct driver installed and working. This is your wireless adapter. Quote:

Did you use the cuttrer program form Broadcom to extract the firmware? |
Actually I just wondering why the laptop wireless device do not recognise any networks?
So, did you mean I should go and configure virtual private network (VPN)? |
I found that two Broadcom 43 and STA wireless drivers are not active and I can`t acitivise them...
