Hi,
Since yesterday's upgrade to ndiswrapper-utils 1.1.4-ububtu2, my
wireless card doe snot work any more. This may or not be related,
because I reverted to the ubuntu1 package and it still doesnt' work. (I
have since reapplied the upgrade.)
I have rmmod'ed the module, deleted the driver (bcmwl5, a Dell 1450
a/b/g), reloaded the driver, modprobe'd ndiswrapper and still nothing.
(I did this before downgrading the package, after downgrading it and
finally afre re-upgrading it.) The driver itself shouldn't be a problem.
I compared /etc/ndiswrapper/bcmwl5 with a backup from when it was
working and they're the same.
The symptoms:
1) When I run ifup wlan0, the card does not get a DHCP offer from my
wireless router:

database - sleeping.
2) iwlist still finds the network:
root at dirac 49 $ iwlist wlan0 scan

4) Ndiswrapper reports all OK (I guess otherwise the scan wouldn't turn
up anything anyway):
root at dirac 53 $ ndiswrapper -l
Installed ndis drivers:
bcmwl5 driver present, hardware present
5) I ran ndiswrapper-buginfo and here's the output:
