Can I somehow reset the router password without losing the RB2011UIAS-RM settings?

Question

network hardware

there is such a router RB2011UIAS-RM, the password is lost, and setting it up again will be quite problematic, since it is not even known what is configured there

Answer 1

Try using the netinstall utility with the Keep old configuration options and a configure script in which you create a new user with administrator rights.
The effectiveness of the solution is not guaranteed.

Answer 2

As written earlier, but subject to amendments, using the utility only with the Keep old configuration parameter set to "ON" (if you do not enable it, it will just reset it to default), then use the "prerelease" software, which will pull you out the password from the user. But all this shamanism is applicable to versions 6.41 and later, that is, on 6.42 such a trick was possible, but he pulled out passwords without special characters.
