First to be a spoiler, the difference between the performance of the 300 routers and the 2000 routers? Tell you, the difference in the data on the book is not great. Does this sound natural? We will not draw conclusions. A simple fact is in front of them. Just like the computer motherboard industry, the same chip set, some motherboards are selling 5,000, and some can only sell a thousand, of which there is a brand sentiment blessing, but more importantly, can The seven-to-one convenience store, like the one that worked all year round, was definitely the 5,000 board, and one thousand might have been blasted for repairs. Like a computer motherboard, what is the most important quality of a router? There is only one answer: stability, ultimate stability, and overriding stability. This route is very cold. NETGEAR is famous for specializing in high-end routers. It has always sniffed down the low-end routers to reduce the network experience. A few days ago, NETGEAR executives also said publicly that they would not To bow down, we must stick to the cold line. Today, we gave everyone a good example of this high-end routing nighthawk X4S R7800 (Nighthawk X4S R7800), and it really felt that it dared to sell 2,000 blocks. R7800 sports car shape and four antennas The NETGEAR router has always given people the impression that: small boxes, no antennas, strange shapes. However, this R7800 is an uncharacteristic, not only absorbed the good genes of the older generation R6300, the whole body uses a wedge-shaped design, in addition to the top surface, the rest are air vents, this cool shape, but also coupled with four modeling A high-performance antenna with a racing deflector sits on the table like a supercar. In the back, R7800 has a LED switch, Reset button, five Gigabit Ethernet port (standard 1 WAN port, 4 LAN port), power connector and power switch button. The four antennas of this router can be disassembled, and the user can select a higher-gain antenna with better performance for replacement. What needs to be pointed out here is that routers filled with antennas like octopus are, to a large extent, compromises that manufacturers have made in order to cater to the user's psychology. Signal strength depends on the signal strength of the chip and the antenna and the router. Not very big, in fact, many high-end routers are not equipped with external antennas, the signal is as strong. Return to R7800 itself. When I took it apart, I saw that the R7800 inherited the rigorous production style of NETGEAR. Considering the exhaust vents, the use of a large number of metal shields can not only prevent static electricity, prevent electromagnetic interference, but also protect the chip. Role, the structure of the metal heat sink, simple and bright motherboard design, of course, coupled with the strict control of the fine workmanship, all add a lot to this router. In the above figure, the R7800 network core is placed inside the largest square metal shield on the left side, and the dual-core 1.7GHz Qualcomm IPQ8065 chip is installed. On the right side are two Qualcomm QCA9984 wireless network chips. Two red and one black wires are used to connect the antenna interface and the wireless network core. In the middle is covered by black waterproof tape, it is a Qualcomm QCA8337 wired network chip. After seeing the motherboard directly, the interfaces connecting the external storage devices on both sides are clear at a glance. The left black waterproof tape covers the two USB ports, while the right side is the eSATA port. 2000 block router is not good speed? When it comes to routers, the first thing to mention is speed. The R7800 wireless router's most proud feature is the AC2600 dual-band wireless network. With five Gigabit wired network ports, the R7800 is undoubtedly one of the top few home routers in the wireless router market. Below, we will test speeds for several network environments. The Internet, when many people use the router, there must be such a question, why does the actual speed and the speed of the family's handling vary? In fact, in most cases, the speed of the network is slower and routers are related. In order to detect whether the R7800 will affect the quality of the network in the daily use of ordinary households, Electric Technology has deliberately used more than a dozen wireless devices to simulate a variety of common home network methods for detection. Briefly describe the test environment here. In the space of 22 square meters, there are 7 computers and 6 mobile phones accessing the router at the same time, and the router is connected to 100M Gehua Broadband. In the access device, two computers perform the Thunder download task, and the rest of the devices perform browsing tasks such as browsing web pages and watching videos. Difference 1: Low network stability packet loss rate In this test environment, we pinged a server address in the "League of Legends" Netcom zone of the game. The ping value of the reaction result floated between 25 and 39. Considering that the TTL return value is low, it will result in the transmission process. Certain losses, so this ping value can be considered very stable. As a comparison, we also used another midrange router with a value of around 300 yuan. In the process of Thunder download, a ping value was detected. It is also a server address. The difference is obvious. Comparing the two, we can see that the network delay of the R7800 is even lower. On average, the R7800 is 33% more powerful than its own 300-yuan router, and the network speed fluctuates less and the number of dropped frames is also lower. Difference 2: Temperature Control Excellent Wireless Stability After a period of stress testing, the temperature of the R7800 was always between 42 and 44 degrees Celsius, and no exaggerated temperatures were produced due to high-strength use. The use of a large number of exhaust channels and metal heat sinks is the key to ensuring that the router continues to stabilize at low temperatures. It is important to note that high temperatures can reduce the effectiveness and useful life of electronic devices and reduce the value of the router in disguise. Of course, seeing such excellent temperature-controlled electricity technology is also somewhat skeptical. Will the R7800's wireless launch capability be weak and the power consumption is not high enough to make it difficult to raise the temperature? So I captured the signal strength over a period of time. As shown in the figure, the same high-intensity operation for a period of time, the R7800 signal strength is still stable, compared with the mid-range router, occasionally the problem of intermittent signals. Different point 3: 2.4 GHz through-wall capability is normal, 5 GHz instead of force When it comes to signal strength, the signal interference of a large number of load-bearing walls is probably the main environmental difference between Chinese and American home routers. Having left the “greenhouse†of American wooden walls, will the R7800 be dissatisfied in foreign land? In this regard, we monitored the signal strength in the absence of walls (4 meters from the router) and a load-bearing wall (6 meters from the router). The following is a monitoring using a thousand yuan Android phone as a sampler. No data results under the condition of passing through the wall Wearing a load bearing wall data results The 2.4GHz and 5GHz attenuation rates are roughly equivalent, which is somewhat surprising. Is this the R7800's 2.4GHz not enough power, or is it 5GHz more powerful? Electrotechnology has conducted the following tests. The figure shows the signal status after wearing a load-bearing wall. The 5GHz signal strength of the R7800 is 14.2% stronger than the 5GHz signal of our own router. What's more exaggerated is that in the bathroom where the signal is blocked very severely, the 5GHz signal of the R7800 is actually seen. . Toilet signal diagram The 5GHz signal of the R7800 can support a wider range of coverage, and letting 5GHz be more than just a synonym for "short range, poor transmission", this should make up for the regret of the R7800 at 2.4GHz. local area network In today's era of mainstream home Internet bandwidth, which is mostly above and below 100Mbps, a Gigabit or higher router is obviously overkill. In fact, the AC2600 class's maximum transmission speed standard is for data transmission within the LAN. Does the R7800 have excellent LAN transmission capabilities? We will use the R7800's easy-to-share to detect if the Gigabit transmission speed is really outstanding. In the case of connecting router Gigabit Ethernet ports, the transmission speed can reach 47.3MB/s. In the use of wireless network, 2.4GHz signal frequency band, the transmission speed is 7.36MB/s. In the use of wireless networks, 5GHz signal band, the transmission speed is 34.6MB/s. Although this data is still a bit away from the theoretical maximum speed that can be achieved by 800M+1733M, considering that the network cable, receiving network card, and other devices used in this test environment are not top-level accessories, the overall performance of R7800 has not been stimulated. come out. However, compared to China’s current use of the most low-end routers below 600M, such data has completely made the R7800 stand out from the crowd. What is worth mentioning here is the easy-to-share feature used to test LAN speeds. The R7800 official firmware has an easy-to-share feature that can be used to share hard disk files attached to the router. With two USB 3.0 ports and one eSATA port on the side, users can flexibly combine storage devices. High scalability can bring more room for easy sharing. With the ultra-high speed, easy to share can easily build a simple NAS for the family. R7800: It is not difficult to be a geek Netgear R7800 may be a tall product in many people's eyes, and the endless loop of third-party firmware has also made many routed novices prohibitive. However, this router is not so difficult to control. The R7800 is also the same as the other routers of the netware. It is optimized for users to use the third-party firmware. This feature is also the place where the R7800 shines. Maybe ordinary users do not understand the firmware upgrade, but the R7800 adopts a full-scale high-pass solution with mature firmware design, and the official firmware integrates most of the leading-edge router functions, such as high-quality QOS services, offline download functions, and easy sharing. Even ordinary users can easily experience a geek life through the R7800. The official firmware will also be upgraded and updated to ensure the maximum user experience. The update method is very simple and can be done with just one keystroke. The specific operation method is to log in the router and enter the setting interface. In the firmware update function page, the latest official firmware can be detected and updated. You can see some changes on the interface before and after the update. The new firmware adds offline downloading of the BETA version. Pre-update version V1.0.0.30 Updated version V1.0.0.30 It may be a coincidence that under the old version of the official firmware, both the signal strength and the wireless transmission speed are far behind the later firmware update. The figure shows the signal strength status before updating the firmware. Referring to the previous pattern, the old firmware is far less effective than the updated one. Of course, in addition to the main interface is more concise and beautiful, in a part of the function settings, R7800 also uses the interface design of the traditional table format, although the efficiency is high, but may not be in line with the Chinese general user preferences. Traditional tabular interface design Gigabit high-speed router R7800, if you have a harsh demand for network stability, or need to set up a high-quality high-speed home LAN environment, then the R7800 this small two thousand price really worth the price.
