hello- how do you block a specific website? what would be the way to do this that would slow the computer down the least? it seems like i should be able to do this with my router/firewall, but there are no settings to do this. i am using a 2wire 'homeportal 1800g' i don't have software firewall, just hardware/ configuration. could i go to a newer, more advanced modem and have this ability?
