[wlug] Wireless networking

29 Dec 2006

      Hi

I am trying to get my wifes computer set up on a wireless network, 
Ubuntu Edgy.
I have a Dynalink / Netcom NP452 network card 88w8835 (libertas) chipset.
I have set up the drivers with ndiswrapper.
All seems OK except access point not associated, as below

noi(a)noi-desktop:~$ sudo iwconfig
lo        no wireless extensions.

wlan0     IEEE 802.11FH  ESSID:off/any 
          Mode:Managed  Frequency:2.442 GHz  Access Point: Not-Associated  
          Bit Rate:1 Mb/s   Sensitivity=-200 dBm 
          RTS thr:2346 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

Yes no signal shows up from the router (Dynalink RTA1025W) -- Linux 
based apparently :-)
but doing a scan picks up two networks.
Mine is the first one.

noi(a)noi-desktop:~$ sudo iwlist wlan0 scan

I have updated the router firmware, I am not sure what to do next.
Rather new to networking, particularly wireless.

Any suggestions appreciated
