Netlink V2801SG Firmware Upgrade

[Abhiabhishek]

I got a new Netlink v2810sg from market and I can't log in the first time itself..it's showing wrong password on using the default username and password..any solutions for this

What username and password did you use?

 

[Abhiabhishek]

admin and stdONU101 tried many combinations ..also tried reset and hard reset ..got a new onu from the shop thinking the first one may have some problems but still no use..and no customer support due to weekend I'm guessing..bsnl guy has bailed on me too

That is weird. It should have revereted to the default credentials after you reset the unit.

See if admin and admin works if you have not already tried it.

Yes it didn't revert back..but finally the issue got solved.. Netlink cc remotely entered his super user password and changed the password.. then upgraded the firmware ..now I have the password and he gave another password to use if I ever reset it again

check if username: user and pwd: user works. Mine had this additional user (feature / backdoor).

Sharing some vulnerabilities. BSNL FTTH has public ip address, so the ONT is accessible from the internet. Its annoying that LCO did not do these simple changes. Most likely for their ease of use - any problems can be fixed by LCO by remotely accessing users, using the exact same default...

Also, can you share that reset password? It was admin / admin for me. Is there any other user also?

After reading your post, I too became ecstatic and flashed the Digisol DG-GR6010 GPON firmware on my Netlink V2801SG and it was successful 😅👍
But I don't see any visible changes in the WEB UI or settings, except for the huge DIGISOL logo on top 😛

i hav Net-link v2801SG and i downloaded the official firmware for GPON and the digisol fw u mentioned too. but when flashing it say integrity check failed.
@whyzee @Morty
the file is .bin and i couldn't open it using iso tools or winrar it says file is invalid
