Looks like either you are pointing to the wrong directory or the file name you entered on the wlc is wrong. Create a folder on your desktop and point the tftp to that and see if that works.

Thank you,

i had to sleep on it to figure out what i was doing wrong.

in the contoler gui i was selecting the tftp directory, i was doing the same within the tftp program. it was messing it up. so in teh controller gui i typed in the file i wanted, but left the file location blank. only after this did the file transfer occur.. thank you for you help in this!
