Xiaomi BE7000 four 2.5G interfaces are really good, don’t buy it if you are a gigabit broadband fan.
My college roommate, Wei, proudly sent me a message last month.: During the fiber optic reconstruction in the community, he upgraded the broadband to 2000 Mbit/s. I replied to him: Your AX3000T still has a Gigabit port. If you enter your house at 2000 Mbit, it will be blocked at 940 at the first door. This is equivalent to spending two dollars to buy one network. He was stunned for a long time, and the next day he turned around and collected a brand new and undismantled Xiaomi BE7000, and asked me to come over the weekend to help with the migration. After all the fussing, I played with it for three days and got to know almost the ins and outs of this machine.
Identify the machine first: BE7000 is not 10,000 Gigabit, don’t be fooled by the number 7,000.
Before buying, distinguish between three machines with names close to each other. This is the step I get asked the most. Xiaomi BE7000 (official name Xiaomi Router 7000) is dual-band WiFi7, 2.4G is 4x4 1147 MB, 5G is 5760 MB, the two are added together to make up the number 7000 ； Xiaomi 10G router It’s another BE10000 priced at 1,799 yuan. It has three bands and dual 10G ports. It’s not in the same price range at all. ； There is also a BE3600 for starters. I used it as the main choice for the $200 budget when I wrote the third-tier budget. The difference between the four versions That article goes into more detail.
The foundation of BE7000 is quite sufficient.: Qualcomm IPQ9554, quad-core A73 running at 1.5GHz, and a dual-core NPU hanging next to it to handle forwarding ； The memory is 1GB, which is four times more generous than the 256MB of the AX3000T. The official nominal capacity is 600 units. The most valuable thing is All four network ports are 2.5G, WAN/LAN adaptive blind insertion , plus a USB3.0. The initial price was 799, and it has been going down in the past two years. Now the new model is hovering around 500, Lao Wei got it at 549, and the good quality Xianyu is over 400.
| model | price range | Network port | Suitable for whom |
|---|---|---|---|
| Xiaomi BE3600 2.5G version | One hundred and sixty yuan | 1 2.5G+3 Gigabit | Gigabit broadband is enough |
| Xiaomi BE7000 | Five hundred yuan | 4 2.5G+USB3.0 | Two gigabit broadband, NAS exceeds gigabit |
| Xiaomi 10G BE10000 | One thousand and eight gears | Dual 10G+4 2.5G | All-flash array, 10G intranet |
who really needs it: Two gigabit broadband is a hurdle
Lao Wei’s original problem was particularly typical.: Used AX3000T for two years There is nothing wrong with the wireless, the card is stuck on the Gigabit WAN port. The 2000Mb broadband was limited to 940 first when entering the door, and the rest was all in vain. Upgrading your broadband without changing your router will cost half the money and lose half the money.
After switching to BE7000, the desktop computer in the study with the 2.5G network card plugged in is wired, and Speedtest goes directly to 1880 trillion , the evening peak is also around 1800. From 940 to 1880, this multiple is visible to the naked eye. It took him more than half the time to download the 80G game package.
By the way, I will do some calculations for those who want to copy the homework.: Lao Wei's 189 integrated package has a monthly fee of 30 yuan more than the original gigabit package, which is 360 yuan a year. The two gigabit bandwidth is really full. The extra half of the speed will cost more than ten yuan a month. He thinks it is worth it. ； If a family of three just watches videos and takes online classes at night, and the usage is not even a fraction of a gigabit, then this 360 is a purely sponsored operator, and there is no need to upgrade the router accordingly.
On the other hand, For families with gigabit broadband and below, the 2.5G port of this machine is just a decoration. . The total bandwidth of your home is more than 900 megabits, and the four 2.5G ports are all idle. An AX3000T or a cheap CR8809 is enough. Pick up the CR8809 article for 95 yuan I wrote about how to choose. There is another place where it is easy to misplace expectations.: The two-gigabit broadband only speeds up the downlink, but the uplink still gives you 50 to 60 megabits. If you want to rely on it to push streams and connect to a NAS remotely, check it out first. How many megabytes of broadband is enough? Don’t count on the wrong direction in that article.
2.5G port connected to NAS: From 110 to 290, this step is the most valuable
Lao Wei's family has an N100 Feiniu NAS, which was previously plugged into the Gigabit port. SMB copying was capped at 110MB/s all year round. On the day of migration, I moved the network cable to the 2.5G port of BE7000 and re-did it in DHCP. Static IP binding , and then copy the same 4K episode folder: Stable between 285 and 295MB/s. Thirty years ago in Hedong, a network port happened.
USB3.0 is also picked up for free. I plugged in a 4T mobile hard disk, opened Samba in the background, and copied Windows directly after mapping.: Read around 90MB/s, write around 70MB/s. It is much better than the 20 to 30 MB write capacity of the old AX series USB port. The quad-core A73 does this effortlessly. If you want to toss in a more complete gameplay, you can watch it Xiaomi router USB interface That article, but to be honest, the positioning of USB hard drives is temporary turnover, and for serious storage, you still need NAS.
A reminder for USB hard drives: First, don’t put anything you don’t trust. Router sharing is basically in plain text. When it comes to encryption, you have to rely on the NAS account system. ； Second, when the mechanical hard disk is connected, it will follow the router's sleep policy and stop spinning after a while if it is not accessed. Next time you click on it, wait for it to start buzzing. A slow beat is normal, so don't take it as broken. Lao Wei's 4T is now dedicated to playing cartoons and broadcasting them directly on the TV, so as not to occupy another space in the NAS.
WiFi7: The benefits of MLO are there, but not everyone enjoys them.
Lao Wei's Xiaomi 14 supports WiFi7, two meters away from the same room, 5G single link negotiates 2882 MB, and the actual test reaches 1830 MB. This number has already brought the two-gigabit broadband to 80% to 90%, and the MLO dual-link superposition is the icing on the cake for him. Should MLO be opened? I wrote a separate article, and the conclusion remains the same.: Only WiFi7 terminals can use it, and it requires dual-band integration, which is a trade-off when there are many IoT devices in the home.
His wife's iPhone 12 can't connect to this number. The WiFi6 machine negotiates 2402, which is actually six to seven hundred megabits, which is no different from the AX3000T. So don’t believe the words “change WiFi7 router to speed up the whole house”. The mobile phone does not support it, and the router’s unilateral efforts are useless. . The attenuation through the wall will not be compromised just because you switched to WiFi7.: I walked to the study room with Xiaomi 14 in my arms, separated by a load-bearing wall, and the price dropped from 1830 to just over 1100. ； There were more than 700 left at the end of the kitchen. The physical laws of the 5G frequency band are the same on any machine. The edge position coverage relies on adding nodes, not stacking parameters.
There is one more thing that needs to be mentioned.: BE7000 is dual-band and does not have the dedicated backhaul frequency band of the tri-band model. There is a network cable from Lao Wei's study room to the weak current box, so it doesn't matter if we use cable for the return trip. ； If we rely on wireless Mesh networking and step into the data band for the return journey, the speed will be half and still have to be discounted. Should I buy two or three Mesh units? The account in that article also applies here. For large apartments that do not have pre-embedded network cables, this machine needs to be considered as a workhorse.
Three pitfalls, think clearly before buying
The first pitfall is flashing. IPQ9554 is too new, and OpenWrt official support has not kept up. It has the same treatment as IPQ53xx in previous years. Why does everyone have one copy of the MT7981 for AX3000T? Brush the OpenWrt article Written very clearly. Buying the BE7000 means buying the official firmware. You have to accept this premise and avoid it if you want to.
The second is fever. The four 2.5G ports were fully plugged in and ran under full load for an afternoon. The casing felt about 48 degrees Celsius, which is within the normal range. However, this machine is positioned to be placed on the surface of the desktop for heat dissipation. Don’t follow the example of Lao Wei who wanted to plug in a weak current box at the beginning. How much is too much? I tried it with a temperature measuring gun. The temperature inside the box would have to be increased by another seven to eight degrees, which is not cost-effective.
The third one is the power supply. Don't replace the original adapter randomly. The output specifications are written on the sticker on the fuselage. Check the voltage and current against the sticker before replacing it with a third party. The current should only be large or small, and the voltage should be accurate. Lao Wei almost fooled him with the 12V power supply in his drawer, but I stopped him. The pitfalls of the power adapter I have written about it before. As for the 128MB flash memory, it is small, and it does not matter if the official firmware is not crowded, and it does not matter if you do not flash the machine. In terms of machine capacity, the official standard is 600 units, and the 58 devices in Lao Wei's family occupy about 30% of the memory. Account with machine volume You can read old articles, but ordinary families are far from the upper limit.
Do you want to add money to tens of trillions?: What can I buy with a price difference of 1,000 yuan?
What Lao Wei asked me the most: Is it okay to add 1,200 and directly connect to the 10G router? My answer is Let’s first see if you have the equipment to eat it . The 10G model has dual 10G ports, one electrical port and one SFP+ optical port. If you want to connect the optical port to a computer, you have to spend more than 200 to buy a module. ； As for the devices at home that can stably exceed 300MB/s in sequential read and write, the only ones are all-flash NAS or SSD pools. The mechanical disk array can last for two to three hundred dollars, and the 2.5G port is just there to serve it. The extra money you spend can't buy a one-megabit speed increase. Now Xiaomi has also released the BE10000 Pro, which is more expensive and unnecessary for home use.
In the end, just one sentence: Upgrade the broadband first, then the router, don’t reverse the order. . Two gigabit broadband plus 2.5G equipment, BE7000 closes your eyes and enters ； If NAS wants to reach Gigabit, this is the best value for money. ； Below Gigabit, AX3000T will be damaged after use. ； If you want to flash your phone, go check out the MT7981 model. Lao Wei's current configuration is a BE7000 main router plus the original AX3000T wired AP to feed the study room. The cost of a set is less than 700 yuan, and the two gigabit broadband is not wasted. The money is spent wisely.
