amazon D-Link DWR-921 reviews

Not only is the traditional wireless router (Wi-Fi router) used in conjunction with the fiber-optic Internet infrastructure, thanks to the addition of a 3G / 4G LTE SIM slot, the DWR-921 also allows users to be proactive. Launch a mobile Wi-Fi hotspot to ‘surf the net’ at the site, temporary office, bus, or in the field trip.

In traveling with family, colleagues or friends, if you choose a popular resort or a relatively large area, most likely users will encounter the status of Wi-Fi network flicker, even Lose the connection when multiple people connect at the same time.

At that time, a telecom operator’s 4G / 3G mobile broadband transmitter was seen as the ultimate solution. However, most mobile Wi-Fi transmitters are currently only able to connect to up to 10 connected devices at the same time. Therefore, it will be difficult to meet the demand for network connection if the group has more members.

Prior to this situation, the D-Link DWR-921 is considered one of the most reasonable solution. The D-Link DWR-921 is basically a Wi-Fi router that supports 802.11n / g with a transfer rate (theoretical) of 300Mbps.

Finally, the point of “value” for this product is the 3G / 4G LTE SIM slot, which allows users to switch to an Internet connection from a fixed WAN port (provided by the carrier’s fiber optic modem Internt) to mobile network.

In this way, users can actively turn this router into a portable Wi-Fi transmitter in cases where the fixed network has problems or when installing the device where there is no network cable.

According to the manufacturer, the D-Link DWR-921 is equipped with a 3G / 4G LTE connection supporting downlink / uplink speeds up to 150 / 50Mbps and capable of meeting the needs of Internet access at the same time 16 device.

In terms of looks, the DWR-921 features a simple, lightweight case, glossy plastic cover and polished edges that blend in with modernity.

The front of the DWR-921 features an encapsulated area dedicated to the signal line with full connectivity status information such as 2G / 3G / 4G LTE, signal strength, and so on. is a button to enable secure WPS connection and hard reset button device.

On the back side, beside the WAN port to receive the “Internet output” from the upper layer modem / router; 4 traditional LAN ports for DWR-921 to connect to PC, printer or other network devices such as IP Camera, NAS, Acess Point; There is a SIM card slot (supports 4G LTE data network) with clear “annotation”, which minimizes user misadjustment of the SIM card.

The D-Link DWR-921 features a total of four 3dBi gain antennas, including two antennas for Wi-Fi signaling and two external antennas for flexible rotation. Exclusively for 3G / 4G LTE cellular networks.

In addition, the DWR-921 also incorporates dual-active firewall (SPI and NAT) as some other dedicated routers to prevent potential attacks on the Internet. The WPA / WPA2 wireless encryption keeps your wireless network safe, allowing you to securely share your 3G / 4G connection without having to worry about unauthorized users accessing your network.

As mentioned above, though, the D-Link DWR-921 only supports Wi-Fi speeds of up to 300Mbps and is not equipped with the latest in wireless technologies such as its dedicated line of products. Experience Lab, Biareview is very pleased and is confident that this router can fully support the provision of Internet for 10 to 12 connected devices at the same time, of course, the speed of the connection. The Internet connection that the user gets will be completely dependent on the 3G / 4G service pack subscription bandwidth and will definitely reduce performance when multiple devices are connected at the same time.

Biareview also appreciates the ability to regulate network operations of the DWR-921 is quite good. More specifically, Biareview has been sharing its Internet connection with the 3G / 4G LTE SIM for an Android TV to stream HD video from online entertainment applications, some smartphones to surf the net.

Watching, even when streaming HD video on a TV screen, members of the test team can completely customize the Internet experience on their phones.

Furthermore, despite being equipped with two 2dBi gain antennas in the body, the DWR-921 also offers the coverage area of 50m2. As such, members can freely move in the living room without worrying about losing connections.

In addition, the Test Lab also found that, in addition to the use of a fixed adapter, the D-Link DWR-921 can also be used on private cars or passenger cars to serve the need. Work and travel of the “owner” of the VIP or passenger, users just need to buy more 12V / 1A charger plugs and USB cable corresponding to the power supply socket of the device.

Think, if the manufacturer adds a microUSB port to the router for use on the mobile charger to extend the performance, the DWR-921 will be more “powerful”.

About the “native” performance of a Wi-Fi router over a WAN, the DWR-921 only achieves speeds of 10 / 100Mbps, but considering the use of this device while traveling it is probably This is enough (!).
