LinuxQuestions.org - trouble with b43-fwcutter in 8.04

im brand new to linux so i apologize in advance if i butcher any terminology, but im trying to get my wireless card (# bcm4311 rev 1 / bcm4312) up and running and have been having some trouble, ive given a pretty detailed description of what ive done so far so if anyone can help id appreciate it

ive been following the how-to at:

http://forumubuntusoftware.info/view...00c8447783b251

and ive got the right drivers for my chipset, first few steps i have no problem with,got the right driver and everything is in right directories, but when i get to step where im am supposed to run

sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

i get the following response:
sudo: ../../b43-fwcutter-011/b43-fwcutter: command not found

so i checked some forums and changed the command to:

su ../../b43-fwcutter-011/b43-fwcutter -w "/lib/firmware/2.6.24-16-generic" wl_apsta.o

which gave me:
su: invalid option -- w
Usage: su [options] [LOGIN]

Options:
-c, --command COMMAND pass COMMAND to the invoked shell
-h, --help display this help message and exit
-, -l, --login make the shell a login shell
-m, -p,
--preserve-environment do not reset environment variables, and keep
the same shell
-s, --shell SHELL use SHELL instead of the default in passwd

so im assuming i need to use -c since im passing a command from one folder to another so i inputed:

su ../../b43-fwcutter-011/b43-fwcutter -c "/lib/firmware/2.6.24-16-generic" wl_apsta.o

which gave me the following error:

Unknown id: ../../b43-fwcutter-011/b43-fwcutter

now ive run out of ideas and have no clue what to try next if anyone can help id appreciate it
