D-Link showed a portable 802.11ac router at CES, too, but it only sounds as though its DIR-510L will be faster than most.
It's a dual-band model, so D-Link is summing the bandwidth of its 2.4- and 5GHz networks in order to market it as a "750 mbps" router.
The D-Link DIR-510L seems pricey at $100, but it has compelling features: It can share a hardwired Internet connection, or you can plug in a 3G/4G USB adapter and share a mobile broadband connection.
You can also plug a USB storage device into its second USB port and stream music and video to UPnP and DLNA-capable clients.
Finally, you can use its onboard 4000-mAh battery to charge other mobile devices such as your smartphone or tablet.
