Hi dear,
Could you tell me what your device is? Because different ONTs and version have different user name and password, for example:
• EG Series
The default user name and password for common users are Epuser and userEp, respectively.
• Other Series
The default user name and password for common users are:
V300R016C10 and before: root and admin, respectively.
V300R017C00 and later: root and adminHW, respectively.
PS: Certain Service Providers may customize accounts and passwords, which are different from the default accounts and passwords listed in the preceding. For details, contact the corresponding Service Provider.
