Think all wireless routers are essentially the same? Like most other hardware, features and performance separate one router from another, and the one you choose can be the difference between getting the Internet service you're paying for, or not. One model that's definitely up to the task is the topic of today's top deal -- it's an Asus RT-N66U Dual Band Wireless N900 Gigabit Router for $125 with free shipping (normally $170; Free 5-port gigabit switch w/ coupon code: [EMCWVWL23]). Dubbed the "Dark Knight," this router rose to the top of our Best of the Best list when we reviewed it back in 2012, earning a perfect 10/10 score. It's range is incredible, it's fast, the antennas are upgradeable, and it even supports DD-WRT.
