Hello, well i am a network administrator. We have bought devices from our distributor. It looks like they have flashed some firmware in the unit. If i work with original huawei device there is default telecomadmin account and wifi ssid HUAWEI-(something) Everything works great and could be setup without problems
This device have Administrator accout : CMCCAdmin and SSID of wifi is CMCC-(something). There is a problem that we can not change things like wifi name, password and another parameters.
So, i think that distributor bought some version of device for china and sold it to us in europe (they flashed some firmware which is not compatible with this device)
EDIT: The telnet is blocked and root user have changed password, in web Maintain Account password could not be changed, still default
