Intel Wifi Link Drivers not working

[jeeves1618]

I have a lenovo x200 and have installed BT4 final and I can get everything working except for the wireless card. If I check the hardware that is being picked up it shows that my card is there. When i check the available drivers that are pre-installed the correct driver is there, but when I do a '/etc/init.d./networking start' the card just kinda hangs out and I get a "No DHCPOFFERS received"

Any thoughts on this would be great.

Maybe I am missing something simple but I just installed BT4 on my Lenovo x200 and have gotten everything else working except for the wireless card. If I look at the hardware the card shows up properly, but when I perform a '/etc/init.d/networking start' I get my ethernet connection to work but the wireless hangs and I get an error

'no DHCPOFFERS reveived'
No working leases in persistent database - sleeping
if-up.d/mountnnfs[wlan0]: waiting for interface eth1 before doing NFS mounts

I then check the network interfaces and I only have eth0 (working) and lo

I also perform a ifconfig wlan0

Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx (shows up correctly)

any thoughts
