Reasons to purchase
In the past few years, my home had been using a TPlink90 spam router. I used a Dlink router the previous year, but it was not easy to use. I sent my friend. Since last year I started using Ruijie's RG-ma1210 router, a very niche router. The market seems to be out of reach now. The stability is first class, but the LAN port is only 100M, wireless is only 2.5G, there is no 5G signal, and the function is slightly less. The router was placed in the study and the signal in the toilet and the second bedroom was reduced to two. I have been looking at routers for a while now, thinking about buying them once, and starting with a high playability point. TPlink, DLink, and other brands will not be considered. ASUS RT-AC88U and other high-end routers are afraid to think. Originally wanted to Taobao bought a well-known netware microwave R6300V2 foreign rubbish to the original when it was more than 200 dollars, the result because they can brush Merlin, let JS scrambled the price to more than 300, the cost of a direct decline.
So every day to see the Avatar Zhang Aunt, search for router preferential information, in the Pamela Forum, found on December 9th Forum "80,000" God released the mesh R6400 Merlin adaptation, and my heart began to R6400 grass. The day before yesterday, I just saw the R6400 of Jingdong's Internet access to engage in spikes. Each piece of 499 can still use 500-100 pods. Therefore, the 508 block of a single line is reduced by 100 after 408.
The dispatch rate of the second-hand East is still very strong. The list of yesterdays will arrive today: 
A big box:
Made in Vietnam:
Unpacking:
Compared with my original RG-ma1210 routing, I feel really big:
Power is also big:
Power on the boot, the official firmware only survived for five minutes, download Merlin firmware, brush machine, everything went well. Why do you not use official firmware, haha, buy this is not to be able to brush Merlin, a tossing person, start with the Eastern official firmware, are embarrassed and say hello:
Regarding why Meilin is brushed, there are the following main points: First, if the broadband used at home supports more dialing, double dialing can be used to increase the bandwidth; secondly, there are rich extension plug-ins to enhance the functions in the road; This router is not to toss it.
In DEBUG mode, open telnet:
TELNET enters the router and backs up the relevant information of the router to prevent bricks from being used to save bricks:
The 80,000-strong Merlin firmware can be directly upgraded from the official firmware. It is very simple:
After restarting the upgrade, be sure to reset it to prevent strange problems:
Smoothly enter the Merlin interface: 
Guest networks, parental controls, etc. all work well:
Adding the tablet computer of the little kid at home to lengthened control and cannot access the internet at a specific time
After the guest network is turned on, friends at home can use the Internet normally, but they are independent and cannot access shared devices at home, such as NAS.
The most important feature of Merlin's firmware is the Software Center, where all kinds of playability features are:
First open the JFFS partition:
Update to Software Center: 
The function of the software center is still very numerous, according to their own needs to download:
Koolproxy, one of the most important features of a variety of advertising, haha, watching video sites, the most cool, advertising, goodbye:
SS, haha, currently applying for a free account for the two sites SS, made a load balance, use extremely cool, GOOGLE, I came to:
After Meilin was brushed, he encountered the problem of 5G signal cut-off and loss. After querying the forum, some netizens said that it was the following problem:
There are 11 US channels for the 2.4G channel and 13 for China. If the region chooses the U.S. channel to be selected automatically, it will only jump back and forth between 1 and 11. Chinese devices can receive it.
There are 12 5G channels in the United States and 4 in China (149 153 157 161). If the region chooses automatic channel selection in the United States and the 5G channel jumps out of the 4 in China, then the Chinese device will search for less than 5G signals. After using the channel for 149 for four days, no loss occurred:
Use ASUS's router management software to manage it normally:
1, because just started, through a few days of testing, is still very satisfied, the price of 399 can also accept.
2, can now brush Meilin firmware, high playability, various functions are still slowly learning.
3, tested in the house, the signal strength is greatly improved than the original router, especially the phone even 5G signal is so cool.
4, 4 Gigabit network port is very cool. Because the home is the Gigabit metropolitan area network, the bandwidth of 100M.
Disadvantages:
1, Meilin firmware there are still some minor problems, such as setting the wireless will restart;
2, the antenna can not be replaced.
