If your "sharing" your internet with roomates and your on the same network (same network address IE192.168.1.*** you should treat the connection as a public connection. Disabling logging on the router stops the router
from logging the site. It does not stop someone on the network from monitoring traffic with any number of free applications. Set up the guest wireless network and have them on a separate wireless network. Make sure your computer is virus free, your OS has all updates including JAVA updates, the website your connecting to is your actual bank (verify the security certificate etc) and never store your password on your computer.
