Hi mate.  You need to be using the "console" connection on the router & not the normal ethernet ports.

Most of these Cisco's come woth a CD containing management software for the console connection.  That also overcomes your password issue.

I'd be asking the tutor for a CD if I were you.  You'll be struggling to get the management software from Cisco.

cheers

Yes, the reset button wipes out any passwords. Here is what it does in detail:
http://www.cisco.com/en/US/prod/collateral/routers/ps380/qa_c67-520756_ps380_Products_Q_and_A_Item.html
Q. What is the purpose of the reset button?
A. The reset button is used to restore the router to the default factory settings if pressed within five seconds of router bootup. Here is how it works:
• The router will not react to the reset button if the button is pressed after the five seconds of bootup.

• When the reset button is pressed within five seconds of bootup and there is no valid xxx.cfg file in the flash memory, the router boots up with the factory defaults stored in NVRAM.

• When the reset button is pressed within five seconds of bootup and there is a valid xxx.cfg file in the flash, the router boots up with the xxx.cfg file and avoids the startup-config file in NVRAM.

You can achieve the same result by resetting the router via the console port. See the section Troubleshooting > Recovering a Lost Password for all variations of resets:
