Unlocking Dasan H660GM-A

1) login to 192.168.1.1 with admin : admin

2) go to maintenance> logs > system logs

3) search for "passwd" on that page

you will most probably get 3 results among them 1 is for default "admin" access, 1 is for a higher level access "superuser", and the other one is for telnet access
(both the username and password will be mentioned there)

4) login with the superuser account and go to maintenance > utilities > acl and enable telnet access for lan and save it

5) open telnet on 192.168.1.1 and then use the password as mentioned earlier in step 3 to login

6) type "bootcfg customer DASAN" and then do a factory reset to unlock the ont

(Note: after unlocking the WebUI credentials will change to admin : vertex25 and this will give you full access to all the settings and the telnet credentials will change to admin : 1234)

imo Dasan has much more advanced features compared to zte(which I used before this) such as separate DNS even for pppoe, beamforming and mu mimo support, inbuilt mesh and more

does anybody know how can we update time on this airtel router H660GM-A (Firmware - V3.2.2120054)?

The NTP settings under Maintenance part of the router admin page is not doing anything. I have tried entering direct IP address of the NTP servers and domain name as well.

I have a static IP and this router is in bridge mode, if that matters.
 
Why do you want to update the time in a bridge mode router?🙂
There's no internet access on a bridge mode router, that's the reason NTP servers are not reachable.
