since i upgraded to ML, i can no longer transfer large files from my win 7 pc (wired) to my mba ml wireless. This only occurs on large files, small files work fine (so i believe its either a time limit issue or file size issue). This also occurs when transfering files to my wired mbp ML. my mba still shows up under network on my win 7 pc, and i can access files, but transfering to it i get a network error. It used to work fine before the ML update. I am fully updated on all machines. any ideas?
