Tenda W900U review: incredibly lightweight 11ac wireless dongle


The Tenda W900U is a wireless 802.11ac USB 2.0 adaptor which uses a Broadcom chipset. This adapter can add wireless 11ac compatibility to any Windows based system (XP to Windows 8) but does not support Apple's OS X operating system. See all Wi-Fi and networking reviews.

The headline feature is the claimed 867 Mb/s figure for its performance on the 5 GHz frequency band, when using an 11ac router.  This is listed because the theoretical maximum for a single antenna transmitting using the AC specification is 433Mb/s. The W900U contains two antennae and therefore its maximum theoretical bandwidth is 867 Mb/s (not 866Mb/s as the numbers are rounded to the nearest integer).

The adapter itself is light in weight, just 19 g, and reasonably well made.  There are no rattles or creaks as you hold or insert it into the computer. The body is white in colour and wrapped in a clear plastic case which seems designed both to protect the adaptor and lend it a stylised look. The body also contains a WPS button for push-button pairing using the standard Wi-Fi Protected Setup system.

The latest 11ac wireless protocol should excel at range so in order to test this we setup a number of scenarios.  All setups used a TP-Link AC1750 router which has three external 5 dBi antennae and so should provide a good signal strength with which to test.

The first setup was a test at 1m from the router to test the maximum throughput of the adapter. Then the router was placed in a 5th floor window and the adapter was attached to a laptop 10m from the building (total distance 18m).  

For the third setup the laptop and adapter were taken 80m from the building (total distance 82m). In all the tests the adaptor was compared against the performance of an early 2011 17in MacBook Pro (Early 2011) with an internal 802.11n card using a 3x3 MIMO antennae setup. Both the 201.11ac and the 802.11n adapter will be using the 5GHz frequency band.

In the first close-range test the adapter achieved a speed of 184 Mb/s. This is in line with the speeds achieved by the current D-Link and Netgear 802.11ac USB adaptors but a little slower than the 200-209 Mb/s of the Asus adapters. At this distance the 802.11n adapter also reached exactly 184 Mb/s.

In the second test the W900U reached a speed of 149 Mb/s, compared to the 802.11n speed of 67 Mb/s. This is also faster than the 125 Mb/s of the D-link DWA-182.

In the final test the W900U returned a speed of 143 Mb/s, almost twice the 86 Mb/s we acheived from 802.11n.

As an additional extreme test, just for fun we took the adaptor 120 m from the building. This even introduced an obstruction from trees, losing a clear line of sight. Even so the adapter still managed to return a speed of 11 Mb/s.

The 2020 Lincoln Aviator gives strong evidence that Ford’s luxury bona fides don’t start and end with the full-size Navigator.
Revealed at the 2018 LA Auto Show, the 2020 Aviator leaps into the niche between the Navigator SUV and the Nautilus crossover, as it revives a nameplate Lincoln hasn’t touched since the 2006 model year.

Asus ZenBook 14 (UX433) Review

Asus has revamped the ZenBook line with a whole new design, including a lighter build, redesigned hinge, and a light-up numpad built right into the touch pad
Should I Buy The Asus ZenBook 14 UX433?
The ZenBook 14 is a very promising shakeup to the Asus laptop line. It’s smaller, lighter, and better looking than any of the previous models, without having to sacrifice either ports or powers. There aren't many laptops around that can offer you a 14in display in a body this compact while still giving you USB-A and HDMI ports, not to mention a Core i7 processor.
Unless you're an Excel addict you can probably safely ignore the glowing numpad - it's a fun gimmick, but most of us will probably forget it's even there, and without tactile feedback it's hardly a proper replacement for the keys. Still, this is a strong enough laptop elsewhere that it doesn't need that gimmick to get by, and there's plenty to recommend it otherwise.

Spider-Man: Into the Spider-Verse Movie Review

Nth Time's a Charm

If you groaned at the thought of another "Spider-Man" movie, fear not because you weren't alone. How many times can one character be rebooted or reimagined before it becomes insufferable? Apparently we aren't there yet, because "Spider-Man: Into the Spider-Verse" is a welcome breath of fresh air.
Everyone's history with the movies about our favorite neighborhood webslinger differs. Sam Raimi's trilogy has its diehard fans (despite only producing one truly great film) and the Andrew Garfield-led "The Amazing Spider-Man" movies were cut short when they didn't meet expectations (the first one is good!). Last year, Jon Watts' "Spider-Man: Homecoming" found Tom Holland in the title role, providing a fun, well-rounded look at the character, which had been missing for a while.
