Second, Tenda AC18 1900M enhanced 11ac dual-band Gigabit router (unpacking & appearance)
Received a large package today, not only big and heavy, but it was not a little guy at first glance
In the thousands of express delivery, I saw the most unique one at a glance. Even the paper boxes were full of Aunt's website and logo.
The packaging is very tight, it is difficult to open the outer paper shell, there are several layers of bubble paper
Remove all the bubble paper and finally you can see the router. Black orange tie, Tenda classic router packaging, overall plastic, the right is the appearance and model of the router, the orange part of the left describes some features and functions of the router
Model:AC18

DC2.1 plug
The gift of a super five cable, very short, only about 1m
Manual, hardware installation and software setup
The last is the router body. The router is also packed in transparent bags to prevent scratches during transportation.
Take out the router, put a shape, still very domineering
The upper right corner is the wireless name and password of the router. If there is no wired connection, the wireless connection will directly make the connection process a lot easier.
The color of the top cover of the router is not a simple black color. Instead, it has a layer of diamond-like sensation on the surface of plastic. The touch is delicate, and the reflection of light from different angles is not the same. The coating is very beautiful.
Tengda's small sign hides the small horn on the left front. The light is the power, WAN, LAN, WPS indicator. The indicator light is blue, not dazzling.
On the right is the 2.4G, 5G, USB3.0, SYS indicator, the appearance of tough, really a little alien feeling
The surface angle is not the same, slightly tilted, the reflective surface has changed
Large and large vents on the sides and top
The last time is the DC power socket, switch, WIFI switch, WPS, Reset, a WAN interface, Gigabit LAN interface
The top cooling hole has a certain opening angle, which not only guarantees the heat emission, but also won't let a lot of dust fall into it.
The antenna is not a cylinder, but a six prism, a strong sense of three-dimensional
The antenna is thick and thin, and the ridge line is from bottom to top
In addition to the necessary labels, pads and hanging holes on the back, there are cooling holes
In addition, there is a USB3.0 interface hidden in front of the router, blocked by a plastic cover
The pad is quite thick and placed very well
Tear off pad, Phillips screws below, four screws on bottom
After removing the screws at the bottom, split along the gaps around, this router has a snap around it and it's tightly attached
The overall top view of the cover is very fine, there is no flaw, and the indicator light uses a light guide.
Open the cover and you can see two huge aluminum passive heat sinks, which is the secret of this router can run for a long time without active cooling
Unscrew the screw and you can see three shields. From left to right, the main SOC area, the 2.4G area, and the 5G area are used. A thermal pad is used between the shield and the passive heat sink to efficiently transfer heat to the heat sink. sheet
Three-snap antenna with buckle design and secondary fixing with tape to prevent falling off
The main SOC is bcm4708
An old SOC, dual-core ARM architecture A9 processor
256MB of South Asian cache, the frequency is DDR3 1600
Both 2.4G and 5G use the bcm4360 chip
Transmission bandwidth up to 1.3Gbps
The aluminum heat sink is very thick, with horizontal bars on the fins to increase the contact area with the air, which is conducive to heat dissipation
Remove the antenna can remove the PCB board, first look at the back, there is a huge memory chip in the lower left corner
Winbond’s 1Gb is a 128MB memory chip
In order to shield the interference, USB3.0 socket is wrapped in metal
Connect to the computer, enter 19.168.0.1 to enter the router settings interface. The first time you enter the setup screen, a welcome screen will appear. Then set the network connection method and password.

USB settings, USB can be set to file sharing, DLNA, printer service
What's left is advanced features. What's surprising is that there is no Qos feature.
More useful speed control in advanced functions
Firewall
The last is the system settings
The following talk about the more interesting app management, first open the app management in the advanced function, and then there is a QR code on the right, scan the code under the app
The name of the app is called Tengda. It is not tall at all.
To enter the interface, you need to register your account via your mobile phone or email, and then enter the registered mobile number or email in the router settings.
You can see the corresponding router in the app. Click the router icon and enter the login password of the router to manage the router. The main interface can see the upload and download speeds of the router. The main functions include parental control, signal optimization, and network deployment.
