I installed ndiswrapper properly. Like I was used to but now I'm somewhere where I can't acces the ESSID with the command:
Code:
Jasper:/home/jasper# iwconfig wlan0
wlan0     IEEE 802.11g  ESSID:off/any
          Mode:Managed  Frequency:2.437 GHz  Access Point: Not-Associated
          Bit Rate:1 Mb/s
          RTS thr:2347 B   Fragment thr:2346 B
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
Jasper:/home/jasper# iwconfig wlan0 essid SANTIS50-6BEC49 
Jasper:/home/jasper# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

sit0      no wireless extensions.

wlan0     IEEE 802.11g  ESSID:off/any
          Mode:Managed  Frequency:2.437 GHz  Access Point: Not-Associated
          Bit Rate:1 Mb/s
          RTS thr:2347 B   Fragment thr:2346 B

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
But when I try the ESSID of my neighbours it does work

Code:
Jasper:/home/jasper# iwconfig wlan0 essid router
Jasper:/home/jasper# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

sit0      no wireless extensions.

wlan0     IEEE 802.11g  ESSID:"router"
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:11:95:01:B2:0A
          Bit Rate:54 Mb/s
          RTS thr:2347 B   Fragment thr:2346 B
          Encryption key:off
          Power Management:off
          Link Quality:48/100  Signal level:-65 dBm  Noise level:-96 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
I just want to mention that the MY router uses mac-security but I added mine to the list so that shouldn't be a problem?
