ZTE ZXHN F660 - Unknown password and name in the configuration panel

Default admin / admin does not work, I cannot enter the configuration panel and the second problem, not directly related to the router, is an error when trying to connect one pc to the homegroup description of the situation:
- I created a homegroup on the laptop
- The stationary cannot join this group any attempt ends with "The homegroup encountered an error"
- Antiviruses and firewalls disabled, the system ones too
- Both computers have the same workgroup and are on the home network
- Computers can be seen in the network environment, although it is not possible to enter the shared folder on the laptop in the normal way, when you enter the address 192.168 ... it enters
I have no ideas what to do, especially since I can't get to the router's panel
I will be grateful for any good advice .

do a hard reset of the router (after this operation, of course, all configuration to be set), then connect the computer, let it get the address from DHCP. In the connection parameters, see what the gate has set and log in to this address.

On question 2, what systems do you have on your computers?

Question 1 - I can not do a hard reset because this router is from the provider and if something goes wrong then I will have to pay .
Question 2 - Windows 7 is on each one

If it is equipment from the supplier, you will certainly not know the security password. The ISP deliberately protects its devices against unauthorized user interference.

The problem lies only in the settings of the computer and laptop, since you can see yourself on the network.
Check if in the advanced settings of the homegroup you have turned on everything correctly (Home profile) and in particular if files and printers are enabled.

What is the service provider?

Whats the topic a bit, but maybe I can help
the password can be easily extracted ;)



and then RouterPassView
and we are looking for


I have another question why DMS does not show all files from the HDD connected to the router?

What is the HDD?

I'm digging up,
buddy uFo will you write something more about this decoding?
I have this device and I do not want to lose the settings, how to recover the admin password?
Thanks in advance

there is more to this slogan

except that instead of accessing the XML file, I get an XPS file and nothing is going to be read from it because the bushes are all, and I would need a password for this router and unfortunately it is missing (and reset is not an option)

I've already written the manual for this device here:


Software version for me


We create a * .html file, e.g. index.html
we edit it with a notebook and enter:




Request Sent ....




save, run the file in any browser, now the config.bin file should pop out
we browse it with the RouterPassView program and look for IGD.AU1, just give ctrl + f

I did as you wrote, unfortunately, it will not work for me, the connection pops up, but I have another ZTE that is lying horizontally with 2 antennas

something like that

see if you can telnet

yes i have access to telnet from root account

find db_user_cfg.xml and edit it

when editing this db_user_cfg.xml file
there are strange characters it cannot be read as it would be encrypted.

zgwałć to telnetem
cat /temp/ppp/options.oe0

I already have it, but is this the data to connect to the service provider so that there is the internet?
I do not want to reset him because I will be without a net.

The matter with this ONU is very simple. I just have one with one of the providers and I have developed a method to extract data from it for PPPoE connection, switch it to transparent mode (bridge) and terminate PPPoE sessions on Mikrotik placed behind it.

As for resetting the device - in properly made networks nothing should be "unprogrammed", because after synchronizing the PON line, the client device gets the entire configuration from the controller using the TR-069 protocol and if the controller detects the factory settings, it uploads its own configuration (devices are recognized by MAC- at the optical interface). The method of "retrieving" this password described here uses a delay between device startup and line synchronization - and then "suction" configuration - just like in cable modems.

After logging in to the root account by telnet, you need to issue the command:
sendcmd 1 DB p WANCPPP

The data contained in the response concern the data required to create a PPPoE client. But it is not everything , because if you want to enable the bridge mode, you will still need a VLAN on which the session is terminated. But this is not harder to read:
sendcmd 1 DB p WANCD

There will be the VLAN number needed to set up the bridge (or create a PPP session after recovering the login credentials).

It is worth writing down the information, because in the next step we will reset the device (from the level of the web panel or the physical button, there is no difference here - just not via telnet because it may end up with a complete memory wipe with ONU firmware and having to flash via TFTP!). It is important that immediately after the device "wakes up" (before the PON line is synchronized) enter the configuration page (user admin , password admin ) and change the default administrator password to your own - The ONU downloads its settings as soon as TR-069 synchronizes the line and if we don't have time now, the ONU controller can change the password itself and cut off our access to the panel. After changing the password, he will not be able to do so, at least not knowing the new password we set.

Attention! I recommend that you change the default password for the root account in telnet because there is a high risk that the router will be infected with a botnet or used to redirect DNS and perform MitM attacks on, for example, banks' websites - automated viruses are ready to perform such activities! The commands for this are (in sequence):
sendcmd 1 DB set TelnetCfg 0 TS_UPwd A new password
sendcmd 1 DB save

Next - if we want to enable the bridge mode, we have to turn it off (change the activation method from Always On on Manual ) the current WAN interface (if the driver has already created it), disconnect it (after saving the changes - Disconnect ) and create a new one by setting its operation mode to Bridged and providing the VLAN number read from the previous steps. You also need to hook up a new bridge ( WAN Port Mapping ) to one of the physical LAN ports. After connecting your own router to this port, you can easily create a PPPoE client on it.
