Hey KevTech, I never save my config because I do not run any applications that required complication operational with the router (etc port forwarding?). Therefore, I backup my router configuration.
I was thinking the same thing that you had mentioned Eddie "you might have a defective router". I do not think the router is defection. There is something wrong with the firmware I think, but I cannot explain properly due too, lack of networking knowledge. When I hit enter with the mouse or keyboard with password had entered, the result are the same "wrong password message". This happened after I ran the router for 2-3 days after I reset the router. For now I ran my router without password-ed because I do not think anyone would want to hack into my router.
