I have set up a few of these CPE710 units and AP and clients. I am having a difficult time this this last one.  I am havng a difficult time getting it to connect to the AP. It lets me set the username and password, but if I log out and try to log back in or it decides to disconnect, when I try to log back on, It tells me that the username or password is in correct.  I have to reset it and start over.  The first time, I thought I typed it in wrong when I set it,  The second time I made sure that I entered it correctly and it still says it is wrong when I try to log back in.  What could the issue be?
