WiFi Card Suddently Not working

[ethernetdan]

I am extremely new to Ubuntu and am having some problems with WiFi. About 2 months or so ago I ordered a new Dell TrueMobile 1350 MiniPCI wifi card and installed it on my Inspiron 5100 laptop. With some difficulty I configured Ndiswrapper. Until now everything has worked fine, Network Manager operated without a hitch and everything was great. Yesterday I turned on the computer and was unable to get WiFi.
Here is the print out from various utilities
lshw -C network:

If I run ndiswrapper -m:

 module configureation contains directive install pci:[[Long string of numbers]] /sbin/modprobe ndiswrapper; you should delete that at /usr/sbin/ndiswrapper-1.9 line 868, <MOD PROBE> Line 7.

It does that almost 15 times with a higher line number at the end each time.

Does anyone have any idea about what I should do next?

Thanks in Advance,
Daniel

I have removed and purged ndiswrapper and reinstalled that and the driver and it still does not work. Does anyone have any tips?

I think you have the same problem as what I had every now and then with Hardy. This is what I did:

1.Go to Network Settings
2.Unlock
3.Highlight Wireless connection and go to the Properties
4.Deselect “Enable roaming mode”
5.Type something in the “Network name” box
6.Under “Connection Settings”, change configuration to DHCP
7.Ok
8.It will show you a “Changing network setting dialogue”.
9.Redo 1-3
10.Select “Enable roaming mode”
11.Ok

If the connection works again then you might consider upgrading your Network Manager to version 0.7. It is explained in this thread: http://ubuntuforums.org/showthread.php?t=797059. I haven't had any problems after the upgrade.
