My route upgrade experience - Asus ACRH17 Reviews
Once a white, tossing routers began with the MTK 7620 architecture, although at the time the BCM5357 and MTK 7620 were midrange routing solutions. However, the MTK7620 is a highly playable, highly integrated design that maximizes the use of third-party firmware.
16 years to start the R6900 router NETGEAR, mainly because the R6900 is much cheaper than the R7000, and you can brush into the Merlin firmware, both of the hardware is very similar, and the performance is very powerful. However, the R6900 does not support MU-MIMO. My wife likes to watch online high-definition video on her mobile phone, and often happens to be stuck. She always suspects that I have limited the speed of her mobile phone. In fact, the transfer rate between the router and the device is not enough. s reason.
From this year's time, MU-MIMO technology began to develop. In addition to routers beginning to support MU-MIMO technology, many terminal equipment also began to support MU-MIMO technology, such as Xiaomi6.
It seems that starting with a router that supports MU-MIMO technology is king.
One, out of the box
ASUS RT-ACRH17 is a dual-band gigabit wireless router with a maximum AC transmission rate of 1700 Mbps.
ACRH17 hardware specifications for the 4-core processor, 128MB ROM, 256MB RAM. The maximum transmission rate of 2.4G is 400Mbps, and the maximum transmission rate of 5G is 1300Mbps. It supports the support of MU-MIMO synchronous streaming technology, and the side of the package identifies product information.
Out of the box
The accessories are mainly routers, power supplies, manuals, and network cables.
The cable should be a Category 6 cable
Power plug output is 12V 2A
router
The appearance of Asus Routing has also begun to set a doll style, from the low-end to mid-range products are not spared, the most obvious difference is the number of antennas.
ACRH17 upper panel shell process is a staggered grid shape, the top panel has 8 indicators, corresponding to power, WIFI, extranet, LAN and other states.
The upper end of the top panel is a horizontal drawing process, separated by a blue line in the middle.
The front panel is shaped as an irregular trapezoid
There are cooling holes on both sides of the router
The back of the router has WPS button, USB 3.0 interface, 4 Gigabit LAN ports, 1 WAN Gigabit Ethernet port, Reset button, power interface, and switch.
Through the bottom it can be seen that the router uses a large area of ​​metal heat sinks inside, and good heat dissipation is a prerequisite for stable work.
The bottom of the router is equipped with 4 small non-slip feet and 2 wall-hung holes.
The router is equipped with 4 antennas, and it is non-detachable. Each degree of freedom can be rotated 180° to adjust the signal strength in different directions.
Second, dismantling
The ACRH17 has 4 pads on the back and 1 screw under each pad.
After removing the screw, open the cover
Upper cover is made of plastic material
Inside the router body
Before disassembling, separate the antenna terminal
Inside the bottom shell has a large number of cooling holes

Chip close-up
The QCA9984 is mainly responsible for data transmission at 5G frequencies and is also the key to implementing MU-MIMO technology.
The processor IPQ4019 is a quad-core processor supporting dual-band 2x2 MU-MIMO at a frequency of 717 MHz.
065FK70324V and 02949EX1719 are signal gain chips.
The QCA8075 is a gigabit switching chip and is responsible for data exchange over Gigabit Ethernet ports.
The back of the main board is covered with a large area heat sink, and the heat sink is very thick.
Remove the heat sink
Motherboard back
The ROM chip model is MX30LF1G18AC, which is from Taiwan Wanghong and has a capacity of 128MB.
The RAM chip model NT5CC128M16IP, from South Asia Yisheng, has a capacity of 256MB.
Third, functional experience
1, APP management
Manage the router on the PC side, as long as there is a little computer base to complete the configuration. ASUS routers can now also be managed through the APP, specifically to experience it.
Download the ASUS Route App by using the market. After the mobile phone opens the APP, it will find the ASUS router by searching the WIFI signal.
Select the router to connect to
Start setting
Set WIFI password
Enter route APP management interface
a, the main interface
Follow the prompts to switch to https connection
Route status
Traffic Statistics
b. Equipment
You can see the devices connected to the router
And limit, speed limit and other management
c. Wireless network
Can manage wireless network name, password, etc.
You can also open and manage guest networks
d, more features
Can perform system monitoring, firmware upgrades, etc.
Plug-ins and third-party extensions are also available
However, the fast network setting function is not very successful. The reason is unknown.
Can't set up under the premise of connected WIFI network
When you can only reset the route to the factory settings, select Manual Settings to configure
2, performance testing
Use IXCHARIOT combination test
Use ASUS USB-AC55 wireless network card to complete the test.
Test the throughput of the NETGEAR ACRH17. The test software is a combination of IXCHARIONT 6.7 and ENDPOINT 7.1.
hardware
A notebook, install ENDPOINT 7.1 server, the laptop through the network cable to connect the router.
One desktop computer with ENDPOINT 7.1 server and IXCHARIONT 6.7 console installed. The desktop connects to the router via USB-AC55.
Two computers access the router ACRH17 through the network cable.
After the connection is complete, the desktop opens the IXCHARIONT console and a new test sample is created. The script type is HIGH_PERFORMANCE_THROUGHPUT. Then edit the test script size according to your needs and set it to 30MB. Run the test and the result is as follows:
PC to notebook
5 PAIRS
Throughput data
Data exchange rate

Node information
10 PAIRS

Through the test data, we can see that the throughput and processing power of ACRH17 has reached the level that a midrange route should have.
Fourth, summary
In fact, the performance of the R6900 is completely sufficient for me, and even excess. However, there is no strong data concurrency capability, resulting in no more high performance. The hardware performance of the ASUS ACRH17 is lower than that of the R6900, but it adds MU-MIMO functionality while maintaining sufficient performance. For real-world applications with multi-device, large-flow, and high-concurrent data transmission, the technical advantages of routers and mobile phones can be fully utilized to tap WIFI transmission available frequency bands to maximize transmission.
advantage:
1. The ASUS router APP has finally achieved universal application. It is easy to use and has good internal heat dissipation.
3, MU-MIMO technology blessing, especially for wireless devices more and more application environment, small and micro enterprises can still fight.
Disadvantages:
1. For the problem that the APP cannot be configured with an extranet, I hope it can be improved.
