Best security to use for wireless router at remote site

[CiscoDHsu]

I have a remote site with cable modem ISP and a wireless router, Cisco 1811W. What is the best security practice to use for this remote site? Can you provide a configuration example?

You can use 802.1x EAP authentication to secure your network. Here is a configuration example which explains in detail how to configure a 1800 router for Wireless connectivity.
