Watch out, ASUS: you're not the only one with an extremely fast WiFi router these days. Netgear has just released the Nighthawk X4, the latest version of its sinister-looking flagship hotspot. The X4's four antennas let it deliver 802.11ac wireless as quickly as possible on any frequency; it offers the same speedy 1.73Gbps as its ASUS rival on the 5GHz band, and a still quick 600Mbps on 2.4GHz. You shouldn't have to worry about your devices starving for bandwidth just because they have to use a less-than-ideal network, in other words. There's also a relatively brawny 1.4GHz dual-core chip inside to keep traffic flowing smoothly, and you can plug hard drives into the eSATA and USB 3.0 ports to share storage throughout your home. This latest Nighthawk is the antithesis of cheap at $280, but you probably can't find a more capable home router right now. Besides, who doesn't want a network box that can masquerade as a stealth fighter?
