just got to thinking, i had to cycle my wifi once i put the modified one in and changed permissions... it should automatically shut it off if i remember correctly but if not definitely do so yourself. (i've done this on two different a500's so i know the process works with whats posted) sorry if its causing you trouble, just make sure you keep your original wpa file incase heh
Humantelope....just to be sure. Could you confirm the file size of the new file is 230.62k?
