Only works if I use particular command line options.

Hi.

Thanks for the quick reply.

AP is access point? I'll give you all the info, just in case I'm wrong
there. The access point is a Dlink G604-T which I own & can reconfigure
if needs be. The NIC is a WG311T. I'm using the current MadWifi drivers,
and the 0.3.2 supplicant code.

Your mention of a possible timing issue clicked when I looked at the
command line options and saw that -Bw means two separate options (I was
trying to dumbly following a howto :>). Leaving the -w in, it works for
me (perhaps I also removed the -w when doing the testing with -d). Sorry
for the false bug report.

My problem now is getting it to work in a bridge configuration. At the
moment, my little test script looks like:

#!/bin/bash
                                                                                                                                                                                                                                                           
while [ -n "$1" ]; do
        case $1 in
                nounload)
                        NOUNLOAD=1
                        ;;
                noload)
                        NOLOAD=1
                        ;;
                nobridge)
                        NOBRIDGE=1
                        ;;
                *)
                        echo "Unrecognised option: $1"
                        exit 1
                        ;;
                esac
                shift
done

fi


And it doesn't work in bridged mode....

I see the activity light on the DLink flicker, so I guess it's receiving
the request, but the reply isn't getting through.
