can't connect to network (wireless)

Hello, I have a Dell Vostro 1500 with an Intel pro 3985 wireless card. The driver that comes with the latest kernel is installed. Running lsmod shows iwl3945.

ifconfig wlan0:

wlan0     Link encap:Ethernet  HWaddr 00:1C:BF:99:B1:DE  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

The wireless card seems to be working, since it detects the network when I run iwlist wlan0 scan:

wlan0     Scan completed :
          Cell 01 - Address: 00:0D:72:4B:2E:F9
                    ESSID:"2WIRE208"
                    Mode:Master
                    Channel:6
                    Frequency:2.437 GHz (Channel 6)
                    Quality=96/100  Signal level=-32 dBm  Noise level=-127 dBm
                    Encryption key:on
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 22 Mb/s
                    Extra:tsf=0000000022a51dd3

When I run iwconfig wlan0 essid 2WIRE208 key ********* and dhclient -d wlan0 I get:

Listening on LPF/wlan0/00:1c:bf:99:b1:de
Sending on   LPF/wlan0/00:1c:bf:99:b1:de
Sending on   Socket/fallback

DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 20
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

I also tried doing it with netcfg2 and using the following configuration:

CONNECTION="wireless"
INTERFACE=wlan0
SCAN=yes
SECURITY=wep
ESSID=2WIRE208
KEY=**********
IP="dhcp"
TIMEOUT=30

Running netcfg with the conf gives me: DHCP IP lease attempt failed.

Can anyone help me find out where I'm going wrong and how to fix it? I feel like I'm doing everything right, but nothing works and most of these tools are horrible in telling me what went wrong...

Re: can't connect to network (wireless)

Can you connect if you disable security? I always try that first... it helps lower down what the issue may be.

Re: can't connect to network (wireless)

The problem has to do with the dhcp server not on the computer but on the router side.  The router dhcp server is not handing out an address, either because you don't have a dhcp server (or maybe it is not enabled in the router) or because there is a limit on the number of simultaneous users ie. there is a maximum of 2 dhcp clients and you are trying to be the 3rd.

Hope that helped

Re: can't connect to network (wireless)

I hope that u use the iwl driver.

I can tell by experience that this driver have bugs that make it hard (extremely hard) to connect to wireless connection. I have an IPW3945, and i use the ipw3945 driver.

Try to use another driver if you can.
