If you had:

• 100mbit Ethernet
• 11g wireless
• router/firewall
• all in one device

and wanted to upgrade to:

• 1gbit Ethernet
• 11n wireless
• router/firewall

would you go with one device or separate them into multiple components? And, what requirements would you have for the component(s)? Lastly, any model recommendations?

Thanks interweb, you're the best! :-)
