configuring wireless

[KaiChong]

Hi there,

I have trouble with setting up my wireless network. the following code is what I got so far:

======================== iwconfig eth1 ==================
eth1      unassociated  ESSID:"dlink"  
          Mode:Managed  Frequency=2.437 GHz  Access Point: Not-Associated   
          Bit Rate:0 kb/s   Tx-Power=20 dBm   Sensitivity=8/0  
          Retry limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:493  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:571   Missed beacon:0
======================== iwlist eth1 =======================
eth1      Scan completed :
          Cell 01 - Address: 00:22:B0:D2:08:D5
                    ESSID:"dlink"
                    Protocol:IEEE 802.11bg
                    Mode:Master
                    Frequency:2.437 GHz (Channel 6)
                    Encryption key:on
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
                              9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
                              48 Mb/s; 54 Mb/s
                    Quality=89/100  Signal level=-39 dBm  
                    Extra: Last beacon: 68ms ago

What should I do now? I tried to configure iwconfig such as essid, mode, and channel, but it didnt work.

after some research and configuration, my wireless card can now find the access point. the code looks like this:

=================== iwconfig eth2 =====================
eth2      IEEE 802.11g  ESSID:"dlink"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:22:B0:D2:08:D5   
          Bit Rate=54 Mb/s   Tx-Power=20 dBm   Sensitivity=8/0  
          Retry limit:7   RTS thr:off   Fragment thr:off
          Encryption key:0000-0000-0000-0000-0000-0000-00   Security mode:open
          Power Management:off
          Link Quality=94/100  Signal level=-31 dBm  Noise level=-89 dBm
          Rx invalid nwid:0  Rx invalid crypt:2042  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:54   Missed beacon:3

but I still can't connect to internet via wireless, I think the reason should be the DHCP connection since I found this:

======================dhclient eth2 ======================
listening on LPF/eth2/00:12:f0:d3:20:2b
Sending on LPF/eth2/00:12:f0:d3:20:2b
Sending on Socket/fallback
DHCPDISCOVER on eth2 to 255.255.255.255 jport 67 interval 8
DHCPDISCOVER on eth2 to 255.255.255.255 jport 67 interval 8
DHCPDISCOVER on eth2 to 255.255.255.255 jport 67 interval 12
DHCPDISCOVER on eth2 to 255.255.255.255 jport 67 interval 14

Can anybody help me out? Thanks in advance

Which distro are you using? Is there a reason you aren't using a network management program, like wicd or networkmanager (the default in most distros)?

[KaiChong]

No, I don't have either wicd nor networkmanager installed in my laptop. Is it necessary?

[MikeTbob]

It isn't necessary but it sure makes life a little easier.
