I have a Dasan h640gw router, which I got from a company that has a fiber optic network. The problem is that I can't log in as root for a long time. I used to do it once, and now I keep showing the message that the password is incorrect, even though I haven't changed it, and I type the...

How do you know that the company has not changed the router configuration.

Because I have the same router all the time and I was able to enter with the same login and password.

Configuration change / update may have been done remotely. Ask the supplier.

The problem is that there was no update, it's the same version all the time.

But it is still the operator's equipment - it changed access data remotely. Maybe precisely because you logged in to it as root - on the operator's servers there are logs of the work of this equipment, it checked and closed your access completely. Connect your own router and tinker there.

Just like a colleague writes @ KOCUREK1970 he could change the configuration remotely regardless of the update.

User account working? user / user ps. This router, by default, has no root account, only admin and user

As there is no default root account as is. The user account works without any problem.

via www is admin and user via telnet is root and admin

We don't know what the supplier is. In Vectra it is so that you can reset their modem to factory settings, and when logging into their server it will be reprogrammed to the state planned by the provider.

Topic summary

The discussion revolves around a user experiencing login issues with a Dasan h640gw router, specifically being unable to access the root account despite using the same password that previously worked. Responses suggest that the router's configuration may have been altered remotely by the service provider, which could explain the login failure. It is noted that the Dasan h640gw router does not have a default root account, and users typically access it via admin or user accounts. Suggestions include checking with the supplier for any changes and considering the use of a personal router for further configuration.
