Access Router Without Admin Password

We have a WRT310N v1 device from Cisco/Linksys.

It was installed by another company and has critical information in it for a dedicated fiber circuit so resetting it is not an option nor do we know the password.  The default password does not work.

It has the stock firmware (from the manufacturer) however we are not sure of the exact version.

Is there any way to get into this router (we have local, physical access to it) to either retrieve the critical information (IP address, subnet, DNS, gateway, et cetera) or is it impossible?

We don't believe it is something overly complicated (such as a 12+ character password generated) yet not obvious as we have tried many combinations.
