Dear Lati,
Thank you for reaching Small Business Support Community and for your time and patience regarding your inquiry.
I would first suggest you to reset the switch; unplug it, wait a minute and plug it back in, then try the console connection through hyperterminal as described in the chapter 4 of the admin guide;

If the problem persists reset the router once more and try the web-based utility as described by the same admin guide, chapter 5.
If you are still unable to login the device I would then suggest you to contact the Small Business Contact Center for further assistance and please do not hesitate to reach me back if there is anything I may assist you with in the meantime.
