The original Linksys E4200 (you can read our review at goo.gl/TEfmG) delivered two 150Mb/s spatial streams on its 2.4GHz radio and three 150Mb/s spatial streams on its 5GHz radio (for theoretical throughput of 300- and 450Mb/s, respectively). This updated model features a new chipset that delivers theoretical throughput of 450Mb/s on both its radios.
So all the changes are under the hood—the enclosure’s industrial design is identical, and that includes the lid that prevents us from plugging hooded Ethernet cables into the four-port gigabit Ethernet switch. We didn’t encounter any problems getting the router to power up a 2.5-inch USB hard drive this time, but it could be because we switched to a newer 500GB drive (we had been using a Verbatim Clōn; we’re now using a Western Digital My Passport Essential). There’s a UPnP media server onboard, but the router is not DLNA certified. If network-attached storage isn’t important to you, the USB port can be used to share a printer instead.
