from my droid?
I've seen apps for Locale called "Wake on Lan" or something to that effect. Uses bluetooth so when you come in proximity, it wakes your computer from hibernate.
I think there are similar apps that might be free, but it's not something I use. My computer wakes pretty darn fast itself
If you set it up that way you can access it outside of your network. Normally you can only access the router config page from a pc physically connected to the router (atleast thats the case with linksys routers), obviously for security purposes. If you do allow outside access Id recommend changing the default port
