wireless connection has Access Point but naught else

My Laptop:
Asus S96s Core 2 Duo T7300
Intel 3945ABG Wireless
Kubuntu 64 bit

Me:
I've used Linux at work for some time but am new to being an administrator / linux box owner.

The problem:

To start off kwifimanager turns off my wireless card and it won't turn on again until I reboot. That is a separate issue I think but ask me for more information on that if you think it is important.

I also intalled wifi-radar but that only seems to do the same as "iwlist scanning" and doesn't actually help connect to a network.

OK so from the command line or (or rather Konsole):

Code:

$ sudo iwconfig eth1 essid Aston-General-Access

Seems to connect me... sort-of.

Here is what I get when I enter iwconfig

Code:

lo        no wireless extensions.

eth0      no wireless extensions.

eth1      IEEE 802.11g  ESSID:"Aston-General-Access"
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:17:0F:E7:75:70
          Bit Rate:18 Mb/s   Tx-Power:15 dBm
          Retry limit:15   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=45/100  Signal level=-85 dBm  Noise level=-86 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:287   Missed beacon:0

So I do have an access point and am displaying a connection speed of about 15Mb/s. However no applications seem to be able to connect. When I have it connected my ethernet connection works fine. I was worried about the signal strength initially but I have tried this in areas with a stronger signal than that displayed above and had the same problems.

entering ifconfig gives the following

Code:

eth0      Link encap:Ethernet  HWaddr 00:1D:60:B8:CC:CB
          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

          Interrupt:17 Base address:0x6000 Memory:fbeff000-fbefffff

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:66 errors:0 dropped:0 overruns:0 frame:0
          TX packets:66 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:5104 (4.9 KB)  TX bytes:5104 (4.9 KB)

Should I be concerned that my wireless card "eth1" is listed as "Link encap:Ethernet" ?

Well, iwconfig says that eth1 is connected to the access point, but you have no IP address.

Try running dhclient eth1 (as root) and see if it gets an IP address from the router. If not, you may need to look into your security settings.

Thanks. I'll try that. In the meantime if you or anyone else could let me know what security setting might be at fault and how I'd go about changing them.

I forgot to mention that I think I had exactly the same problem with connecting to a password-protected network: Once I entered the correct password and essid I got an access point but connection (presumably no IP as above).

Thanks again

I'm like totally connected. Cheers.
