First of all, I have to say that I am a new user of Ubuntu and I am not familiar with it at all... After installing Ubuntu 12.10 it would not recognise the wireless networks available... How do I fix this?

After trying the Wireless troubleshooting the results are:

  1. The device is on!

  2. The output of the terminal lshw -C network is :

  3. I tried with no success to find the windows driver, so I cannot use the windows wireless drivers.

  4. The output of the terminal iwconfig is :

      eth0      no wireless extensions.
  lo        no wireless extensions.

  5. The output of ifconfig is: 

    eth0      Link encap:Ethernet  HWaddr 4c:72:b9:83:7b:1e  
    inet addr:192.168.10.17  Bcast:192.168.10.255  Mask:255.255.255.0

  6. The output of the terminal ping -c3 85.190.27.2 is : 

    PING 85.190.27.2 (85.190.27.2) 56(84) bytes of data.

--- 85.190.27.2 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2014ms

  7. The output of the terminal ping www.ubuntu.com is:

    64 bytes from avocado.canonical.com (91.189.90.40): 
    icmp_req=1 ttl=50 time=112 ms

    a thousand times

  8. No output with the terminal gksudo gedit /etc/modprobe.d/aliases !!

I must be doing something ....

As you are new to Ubuntu I request you to go through the Ubuntu Official Documentation Wireless troubleshooting
