Download Driver TRENDnet TEW-684UB USB Wifi Adapter

Download Driver TRENDnet TEW-684UB USB Wifi Adapter. This time we are dealing with the TRENDnet TEW-684UB, USB adapter Wi-Fi N dual-band (2.4GHz and 5GHz) 450Mbps destined to beat in performance testing to all adapters that have previously tested.

TRENDnet TEW-684UB Technical Features
Interface: USB 2.0. Supported Standards: IEEE 802.11a / b / g / n (2.4GHz and 5GHz bands). Receiving Sensitivity: 802.11b: -87dBm at 11Mbps; 802.11g: 54Mbps -72dBm; 802.11n / g: -65dBm at 450Mbps; 802.11n / a: -64dBm to 450Mbps. Output Power: 12dBm 802.11a; 18dBm 802.11b; 15dBm 802.11g; 802.11n / g of 15dBm; 802.11n / a of 12dBm. CPU: Ralink RT3573L P4M3870400 with Three Stream to get the 450Mbps. Wireless Amplifier: SiGe 5512L 113AX and Antena 3 2 dBi antennas for the 2.4GHz band and 1dBi for the 5GHz band according to specifications.

TRENDnet TEW-684UB External analysis
As we have done before in this part, we will physically see the device to analyze and compare it with its big brother, the TEW-687GA, since they have the same physical appearance. In the back we can see the connection with other computers on the same brand and a brief description of computer buttons and connections. Also indicates compatibility with operating systems (Windows as indicated, but will try this adapter also with Ubuntu).

Detail WPS button for quick connection to the access point without meter long and complicated keys. They simultaneously pressing the button on the router and button this adapter will automatically sync (for 1 minute for safety). At the bottom of the equipment we adapter's MAC address and serial number and hardware version of this adapter (v.1.0R). Now about the size, the next picture you can see a standard USB 2.0 connector and equipment, both are in the same line with the same perspective, you can appreciate the small size it has. We have 3 LED indicating different states. WPS status (active or not), status of the wireless network (if we are connected to AP or not) and status POWER (if you have connected).

TRENDnet TEW-684UB Internal Analysis
It is time to open the USB adapter to see all its components, I advance that has all the components that a router or access point as they are not needed. The first thing we do to remove it is to remove the rubber mat at the bottom and remove the screws beneath said gum. The CPU of this WiFi adapter is Ralink RT3573L, is a 3T3R with three amplifiers and three internal antennas, Three Stream incorporates technology to get 450Mbps. It supports WPS for quick synchronization, both PCB (button) as PIN number, also incorporates QoS-WMM to transfer data at the maximum possible speed, and WMM Power Save for saving energy, look very important because this is a laptop and often will be powered by batteries. Nor can we forget the MIMO (Multiple In, Multiple Out) that these speeds is critical, incorporates MIMO Power Saving for saving energy. This device supports a bandwidth of 20MHz / 40MHz, also supports all types of wireless encrypted people today. The amplifiers are SiGe 5512L Wireless 113AX. Currently we can not show you the official Datasheet as we have done previously, because they have not posted on the official website Ralink.

Evidence of this adapter will make the 2 routers: TRENDnet TEW-691GR, and Cisco Linksys E4200 (2.4GHz and 5GHz) to check the performance of the double band. If we receive the new TRENDnet TEW-692GR with simultaneous dual-band 450Mbps update this review to put the new measurements with this equipment.

Software TRENDnet
Together with the USB Wi-Fi adapter, comes a CD with a utility to manage TRENDnet computer in Windows operating systems. Here are some screenshots of the software and its different functions we put. The main screen of the software is as follows, where we see general information about our wireless connection. If we click on the buttons above, we will open more windows beside the main window. With this software we can put this adapter Wi-Fi in AP mode to connect to it, thus forming an ad-hoc network between computers. It also supports Wi-Fi Direct, What is Wi-Fi Direct? Read this article.

Another option is to Infrastructure + AP (STA + AP), ie you connect to an access point in client mode while our card acts as AP could say that repeater that wireless signal becomes, or better rather, it becomes in WDS + AP mode (WDS because it is linked to the router and AP because it creates a different SSID). This software includes USB Wi-Fi adapter is easy to install and operate, provides data signal and power received. It also gives us the ability to use Wi-Fi Direct and put the adapter in AP mode and all from the same program. We have been quite pleased with its performance.

TRENDnet TEW-684UB Conclusions
The Wi-Fi USB adapter that today we have presented has regained all other adapters, including mini-PCI cards Intel laptops. TRENDnet has again broken all records that previously had in our comparative Wi-Fi adapters. In addition, the included software provides extra features to make the most of our new USB adapter. Not only has behaved excellently with the TEW-691GR, giving maximum performance (sometimes even better than the TEW-687GA), but the band 5GHz with Cisco Linksys E4200 and a CPU Broadcom is has behaved excellently. This team may use interchangeably with Ralink CPU (which will give you the most for your support) and Broadcom CPU.
