[ Huaqiang Security Network News ] I often hear from friends that the broadband router has a problem. Today, I will analyze the problem of the broadband router crash, and see what causes these problems. 
1, from the session said the number of machines caused by the number of crashes <br> Many manufacturers in the promotion of their own broadband router products will generally mention a number of connected machines, most manufacturers will say their four broadband router can With a machine 10-20 sets. However, some users will have a crash when they are in the process of using the machine. In the process of purchasing, we first need to analyze whether the number of broadband routers and their own machines and applications match. Sometimes, because the actual environment is not suitable for using the purchased product, there will be a phenomenon that the broadband router can not bear the network load at all, and the problem of the crash is dropped.
From a technical point of view, we usually talk about the performance of the NetIQ Chariot software test (smartbit purchase cost is too high), and one session (Chinese name session) evaluation can explain some problems. In the IT168 evaluation of the four-port broadband router, generally use this session option in the test, throughput and processing performance we will not talk about, let alone talk about this option directly related to the number of machines. Generally, a broadband router with better performance can establish 300 pairs of sessions at the same time. And almost only can reach 200 pairs of conversations.
We assume that the broadband router has 10 units (here, the connections from the internal network to the external network are mentioned. The connection between the internal networks is based on the switching port of the broadband router, which can basically reach the nominal value of 100 megabytes). When the computer needs to access the WEB page, the broadband router will initiate a session request after entering a domain name in the browser. After the website server receives the request, a response will be returned to the broadband router, and a session will be established. . If these ten machines open 10 pages at the same time, plus QQ, MSN and download tools, etc., each machine needs to establish 20 pair sessions. Ten machines are 200 pair sessions.
Under this load, the general broadband router should be able to operate normally, but when 20 machines are used, it is believed that there will be more applications in the network, and the broadband router will be down. From this example, we can see that in some scenarios of network applications and machines, the home-grade 4-port broadband router is simply not applicable. And some users have bought a home with a 4-port broadband router to do the shared gateway of a small Internet cafe, I think it is not surprising to see the crash.
In summary, when purchasing a broadband router, we must consider the number and needs of our own belts. Do not engage in a small horse-drawn cart, causing unnecessary trouble and economic losses.
2. What is the worst product that users have reported the most deadlocks?
On the online BBS, you can often see that there are many users who are experiencing crashes during the use of some products, but some products do not see such comments. Can these comments indicate that this product is really the worst? I have never used a broadband router before, so I mistakenly think that the broadband router does have many product defects. I once talked about this problem inadvertently chatting with a dealer who sells a broadband router in Beijing. He said that the facts are not the case. From an objective point of view, it is impossible for any manufacturer to achieve a zero percent defect rate, and every product produced by the product is qualified.
Readers may ask, is this defective rate related to the problem of broadband router crashes? Here we give you an example to explain this problem.
It is assumed here that there are A products and B products, and both products are also one in ten thousand defective products. A products are sold in the market with 100,000 units, while B products are only sold in the market for 10,000 units. According to the ratio of one ten thousandth, there are ten products in A products that may have problems, while B products only have problems. There may be a problem with one product. At this time, we can find that the ten users who use the A product will be dissatisfied with the product, and only one user of the B product will be dissatisfied with the product.
From the above analysis, we can see that many broadband routers in the market encounter the problem of deadlock during use. This may be caused by problems in the production process of individual products, but this is not enough to explain the model. There will be problems with the product crashing. Since I later used the broadband router product myself, I found that the product is still very stable, and there is no crash problem mentioned by netizens. Therefore, I personally feel that these netizens’ comments are only cases, not universal problems. .
Of course, from the user's point of view, we hope that the broadband routers produced by the manufacturers can be used by users with confidence, but some manufacturers' products are indeed due to the unqualified product quality, which is not included in the list. Therefore, the evaluation of some products on the Internet does not mean that all products of the broadband router are problematic. We cannot overwhelm a boatman.
3, the user's technical level is limited, the crash caused by improper installation <br> We know that among the users of broadband router products, the technical level is uneven, many users only know a little about the broadband router products and technology For most of the settings of broadband routers are not very well understood. The dealer also told me that many users will not set up after buying the broadband router, and he has done things in a few minutes. Therefore, sometimes the problem of improper setting causes the broadband router to crash.
When encountering such problems, we hope that users can face it with the right attitude, carefully check the product manual, and communicate with the after-sales service personnel in time to accurately determine the cause of the crash. If it is indeed a product quality problem, the manufacturer will also give the user a good solution to the problem. If the manufacturer ignores the phenomenon, we will use some media to reflect the problem and arouse the attention of the manufacturer to take a positive attitude. The embarrassment on the Internet, the author believes that it is an irrational performance, and ultimately will not solve the actual problem.
4, the quality of the access line is poor, the problem of the crash caused by the virus problem is the majority <br> In addition to the problem of improper use of the user will cause the broadband router to operate abnormally, the quality of the access line is poor, the virus is also causing the broadband router An important factor in the phenomenon of dropped calls. From the broadband installation process I have experienced, I found that there are big problems with China's Internet access lines. For example, ADSL lines, the technology itself has very high requirements for the quality of telephone lines, and in some old residential buildings, the use of older telephone lines, the line quality itself is barely coping with the basic call function, in this environment, how can Guarantee the normal operation of the ADSL line?
For example, Great Wall Broadband, my home is installed Great Wall broadband, in order to save costs, the length and width of the wiring in the building using a twisted pair to separate two pairs of lines to access two households, this wiring is a poor quality In the wiring project, the eight pairs of cables in the line are used at the same time, greatly increasing the possibility of signal interference. Such a broadband line sometimes causes frequent disconnection. After the line is dropped, the user cannot find the cause, and it may be unclear that the problem is a broadband router.
Users with a little bit of network knowledge may know that if a virus appears on the network, it sometimes causes the whole network to be paralyzed. Some network viruses will specifically attack specific ports of the broadband router or continuously send broadcast packets on the network. When this happens, the broadband router will cause problems such as crashes due to heavy load. After the above analysis, we recommend that users should carefully check whether there is a virus or the like in the computer when such problems occur.
to sum up:
Above, we did some objective analysis on the crash of the broadband router. The text does not favor users or cover the manufacturers. I just hope that everyone has a correct understanding of the broadband router. I hope all users can use this better. Class products, truly achieve the purpose of high-speed shared Internet access.
