D-Link DWR-921

amazon D-Link DWR-921 reviews

Not only is the traditional wireless router (Wi-Fi router) used in conjunction with fiber optic Internet infrastructure, thanks to the addition of 3G / 4G LTE SIM slot, DWR-921 also allows active users deploy a mobile Wi-Fi hotspot to ‘online’ at the construction, temporary office, passenger car or in picnics, travel.

In trips with family, colleagues or friends, if you choose a budget resort or have a relatively large area, most users will inevitably experience a flickering Wi-Fi network, even It is just losing connection when more people connect at the same time.

At that time, a mobile Wi-Fi transmitter that exploited 4G / 3G bandwidth of the telecom operator was seen as the most rescue solution in such occasions. However, most portable Wi-Fi transmitters today can only ensure connectivity for 10 connected devices at the same time. Therefore, it will be difficult to meet the network connection needs if your group has more members.

Before this situation, D-Link DWR-921 is considered one of the most reasonable solutions. Accordingly, the D-Link DWR-921 is basically a wireless router (Wi-Fi Router) that supports 802.11n / g standard with data transfer rate (theoretically) at 300Mbps.

And yet, the point of creating “value” for this product is 3G / 4G LTE SIM slot, allowing users to switch Internet connection from fixed WAN port (provided from fiber optic modem of service provider Internet) to mobile network.

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

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

In terms of appearance, the DWR-921 has a simple design with a compact box shape, glossy plastic exterior and well-rounded corners and color schemes that show off the modernity.

The front edge of the DWR-921 features an area encapsulated exclusively for signal lights with full information on connection status such as 2G / 3G / 4G LTE, signal strength, … attached. is a button that activates the WPS secure connection feature and a hard reset device button.

On the back side, next to the WAN port to receive “Internet output” from the modem / router above; 4 traditional LAN ports for the DWR-921 to connect to a PC, printer or other network devices such as IP Camera, NAS drive, Acess Point; There is also a SIM card slot (support for 4G LTE standard data network) with a clear “caption”, which helps to minimize the user status of the wrong way of the SIM card.

Manufacturer representative said, D-Link DWR-921 equipped with a total of 4 antennas 3dBi gain , of which 2 underground antennas for broadcasting Wi-Fi signals and 2 external antennas with flexible rotation capabilities specifically for 3G / 4G LTE mobile network.

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

As mentioned above, although the D-Link DWR-921 only supports Wi-Fi speeds at 300Mbps and is not equipped with many outstanding wireless technologies such as its dedicated product lines, but through Practical experience, Biareview feels very satisfied and reassures that this router can completely meet the provision of continuous Internet for 10 to 12 devices connected up at the same time, probably of course speed The Internet connection the user has will depend entirely on the bandwidth of the registered 3G / 4G service package and will certainly reduce the productivity when multiple devices are connected at the same time.

And yet, Biareview highly appreciates the DWR-921’s ability to regulate network tasks. More specifically, Biareview has shared Internet connection provided from SIM 3G / 4G LTE for an Android TV to transmit HD video from online entertainment applications and some other smartphones to surf the Internet.

According to observation, even when streaming HD-standard videos on a TV screen, members of the test team can also freely experience the Internet on their phones.

Moreover, although equipped with 2 underground 2dBi gain antennas in the camera body, the DWR-921 also offers coverage that can “embrace” the living room space of about 50m2. Thus, members of Biareview can freely move in the living room without worrying about losing the connection.

In addition, Biareview also found that, besides using in the hotel because only using fixed adapter, but D-Link DWR-921 can also be used on personal cars or passenger cars to serve the solution needs. to work and work mobile of “VIP” owner or passenger, users only need to buy additional 12V / 1A type charger pipes (attached to the cigarette primer head) and USB cable corresponding to the device’s power supply jack standard .

Thinking, if the integrated manufacturer gives this router a microUSB port to use via a mobile charger to expand its performance, it is certain that the DWR-921 will become “more efficient”.

In terms of “original” performance as a Wi-Fi router over the WAN, the DWR-921 only reaches 10 / 100Mbps, but considering the use of this device when traveling, perhaps This is more than enough (!).

Easy to use, attractive management features

Not beyond the expectations of Biareview, D-Link DWR-921 is also integrated with D-Link’s fast configuration interface similar to its other Wi-Fi router series, allowing users to simplify Turn on setup operations and quickly bring this device “airplay” according to its own configuration.

Once the configuration is complete, right at the Internet settings interface, users can modify the default parameters such as LAN address layer, or option to exploit Internet from WAN port through upper layer router according to mechanism for allocating static / dynamic IP addresses or via 3G / 4G data networks

Also here, users can enable the feature that is considered to be the most special on this router – automatically switching the Failover signal source.

Basically, this is a feature that helps the D-Link DWR-921 to establish a backup Internet connection based on the signal level from the WAN port or 4G / 3G SIM card. More specifically, when the traditional Internet output – ie the WAN port – is disconnected due to network failure, the DWR-921 will immediately transfer the signal to the pre-configured 4G / 3G data network, and backwards.

This allows users to continually experience the Internet without having to worry about network drops or glitches.

Accordingly, in the Failover interface, if you are selecting the default Internet output (Primary WAN) as a signal from the WAN port, you only need to select the 4G network in the drop down menu Secondary WAN, and vice versa.

According to Biareview, in the Remote Host for Keep Alive section, DWR-921 has been configured to the default address of Google’s DNS server (ie 8.8.8.8). Therefore, if you are a network administrator, you can customize this parameter as you like.

With the Wi-Fi network created by the DWR-921, users can actively rename the SSID as well as the new login password as desired, WEP / WPA / WPA2 or WPS encryption standard.

In addition, the DWR-921 also integrates some basic network management features such as QoS – Priority bandwidth for critical equipment, URL Filter – allows / blocks specific website addresses, Schedules – Set timetable for each specific device, …

And yet, this router also integrates some advanced features for network infrastructure administrators such as DNS, DMZ, Virtual Network, ….

Replace the ending

With support for integrated 4G LTE, the DWR-921 is the ideal solution for creating a fast wireless network, giving users maximum flexibility in working, studying and entertaining all things. Even though it’s anywhere.

And yet, this 4G Wi-Fi Router is also a savior for apartments and offices that are not yet fitted with fiber-optic Internet lines. Even the DWR-921 can be used in buses, trains or boats, allowing passengers to check e-mail and chat online while on the move.
