DIR-825 Xtreme N Dual Band Gigabit Router
http://www.dlink.ca/products/?pid=681
This is the router I use at home. It's been running for a full year without a single reset.
You can set up two separate networks with this router, each will have their own security. I use one with WEP to support my older devices and WPA/WPA2 for my newer stuff.
My router is in the basement and I get connection throughout my 2-storey house
