LinuxQuestions.org - Fedora Core 2/BCM4309 - scan works but no IP address...

Hi
This is my first ever post here... :D

I'm using Fedora Core 2 with KDE 3.3.1 on a Dell Inspiron 8600, I've installed ndiswrapper to allow my "truemobile 1400" aka Broadcom Corporation BCM4309 802.11a/b/g (rev 02) wireless card to access my AP, a D Link 724p+

The install of ndiswrapper looks to have run ok with a simple make install. These messages have been logged:

Oct 23 07:45:38 localhost kernel: ndiswrapper version 0.11 loaded (preempt=no,smp=no)
Oct 23 07:45:38 localhost kernel: ndiswrapper: using irq 7
Oct 23 07:45:38 localhost kernel: wlan0: ndiswrapper ethernet device <mac addr> using driver bcmwl5a
Oct 23 07:45:38 localhost kernel: ndiswrapper: driver bcmwl5a (Broadcom,06/25/2004, 3.40.73.0) added

I can add the essid and wep key via iwconfig ok with no problems... and an iwlist wlan0 scan gives me a result (but only when I set the essid parameter in iwconfig)
I can only set the wep key before the essid is set.

This is where it gets interesting... the Cell 01 - Address value doesn't match the MAC address of my Wireless Access point. (and the Protocol in iwlist differs from that in iwconfig) I believe this may be causing the problems I'm finding.
This may even be my neighbour's AP which is unsecured. This is a bit weird given my AP is 3 metres away and my neighbours AP is "somewhere".

Anyway, when I try to get an IP address on wlan0 I get nothing. If I'm connecting to my AP *or* the neighbours I should get some form of 192.168 address ?

ifconfig results:

]# ifconfig

ifup results

]# ifup wlan0
Determining IP information for wlan0... failed.

logs report:

Oct 23 10:24:41 localhost dhclient: No DHCPOFFERS received.

So is it the wireless router or the card or the driver, this is the bit I have yet to work out?

I can ping 192.168.0.1 via eth0 but not via wlan0, if I unplug my cable on eth0, I get no connectivity at all.

Hope someone can help?
