unable to log into the admin settings on my Panoramic router

trying to log into my router but unable to get in i know the username is admin because when i tried to use user or user id or password in the admin spot it says that its not a user name but when i put in admin it tells me the password is wrong and with admin ive tried password, admin, user, userid  dont know what else to try i didnt change it myself this is my first time logging into the router since i got it so i know it wasnt changed...
