hello guys. need help here. i recently install prolink H5004N router/modem. it was working fine until i upgraded the firmware. when i access the router page 192.168.1.1, in its new firmware it has the "quick setup" tab. it ask the "connection to internet user and password" in which i have no idea. do i need to set the thing up manually? i forgot to backup its default settings/firmware, stupid of me. anyway any help guys?
