Analysis of the cause of the router crashing and dropping
Today, the author conducts an objective analysis of the problem of broadband router crashes and drops to see what causes these problems. It is often seen on the Internet that after buying a broadband router, many netizens experience frequent crashes and crashes during use. This has caused a lot of inconvenience to netizens, and some products have been worthless.
1. From the session, the number of dropped machines caused by offline
Many manufacturers generally mention a number of connected machines when they advertise their broadband router products. Most manufacturers will say that their four-port broadband router can carry 10-20 machines. However, in the process of use, some users will crash after 10 units are brought online. During the purchase process, we first need to analyze whether the number of our broadband routers and their machines match the application. Sometimes, because the actual environment is not suitable for using the purchased product, there will be a phenomenon that the broadband router simply cannot bear the network load, and the problem of crashing and disconnection occurs.
From a technical point of view, we usually talk about the performance of products tested with NeTIQ Chariot software (the purchase cost of smartbit is too high), and one of the session (Chinese name session) evaluation can explain some problems. The four-port broadband router evaluated in IT168 will generally use this session option in the test. We will not talk about throughput and processing performance for now, but only talk about this option that is directly related to the number of belt machines. Generally, broadband routes with better performance can establish 300 pairs of sessions at the same time. And almost can only reach 200 pairs of sessions.
Let ’s assume that 10 broadband routers are installed (all connections from the internal network to the external network are mentioned here. The connection between the internal networks is based on the switching port of the broadband router, which can basically be close to the nominal value of 100M), 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 web server receives this 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, download tools, etc., each machine must establish 20 pair sessions. Ten machines are 200 pair sessions.
Under this load, general broadband routers should be able to run normally, but when 20 machines are used, I believe that with more network applications, the broadband router will crash. From this example, we can see that in some scenarios with many network applications and machines, a home-grade 4-port broadband router is simply not applicable. And some users use the 4-port broadband router as a shared gateway for small Internet cafes. I don't think it's not surprising that the phone crashed.
To sum up, when we buy a broadband router, we must take into consideration the number and needs of our own machines. Do not make a small horse-drawn cart, causing unnecessary trouble and economic losses to ourselves.
2.Does netizens report that the product with the most crash problems is the worst?
On the online BBS, you can often see that some products have a lot of users experiencing crashes during the use process, and 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 thought that there are many product defects in the broadband router. When I accidentally chatted with a dealer who sells a broadband router in Beijing Talking about this issue, he said that the facts are not the case. From an objective point of view, no manufacturer can achieve a zero-percent defect rate, and every product produced is qualified.
Readers may ask, is this defective rate related to the problem of broadband router crashing and dropping? Here we will give you an example to explain this problem.
It is assumed here that there are product A and product B. Both products are also inferior in 10,000. Product A sold 100,000 units on the market, while product B only sold 10,000 units on the market. According to the ratio of 1 in 10,000, product A will have 10 products that may have problems, while product B only 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, while only one user of the B product will be dissatisfied with the product.
From the above analysis, we can see that many broadband routers on the market encounter the problem of crash and disconnection during use. This may be caused by problems in the production process of individual products, but this is not enough to explain this model. The product will have the problem of crashing and dropping. Since I later used a broadband router product myself, I found that its product is still very stable, and there are no crashes and offline problems mentioned by netizens. .
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 unqualified product quality and cause crashes. Therefore, the evaluation of some products on the Internet does not mean that all the products of the broadband router are problematic, and we cannot overthrow a boat with one shot.
3. The user's technical level is limited, and the crash caused by improper settings
We know that among users who use broadband router products, the technical level is uneven. Many users only know a little about the products and technologies of broadband routers, and are not very familiar with the settings of most broadband routers. The dealer also told me that many users will not set up after buying the broadband router, and he has done it in a few minutes. So sometimes it will encounter the problem of improper setting causing the broadband router to go offline and crash.
When encountering this kind of problem, we hope that users can also face it with a correct attitude, carefully check the product instruction 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 users a good solution to the problem. If the manufacturer ignores the phenomenon, we will reflect the problem through some media, arouse the manufacturer's attention, and take a positive attitude. Abuse on the Internet, the author thinks it is an irrational performance, and ultimately will not solve the actual problem.
4. Poor access line quality and virus crashes caused by the majority of crashes
In addition to the problem of improper use of the user's settings, which will cause the broadband router to operate abnormally, poor access line quality and viruses are also important factors that cause the broadband router to drop and crash. From several broadband installation processes I have experienced myself It is found that China's Internet access line has great problems. For example, the ADSL line has high technical requirements for the quality of the telephone line. In some old residential buildings, the older telephone lines are used. The line quality itself is barely coped with the basic call function. In this environment, how can How to ensure the normal operation of ADSL lines?
Another example is the Great Wall Broadband. In my own house, the Great Wall Broadband is installed. In order to save costs, the wiring in the building uses a twisted pair to separate two pairs of lines and connect them to two households. This kind of wiring is inferior. In the wiring project, the eight pairs of cables in the line are all in use at the same time, greatly increasing the possibility of signal interference. Such a broadband line sometimes causes frequent disconnection. After the disconnection, the user cannot find the reason, and it may be unclear that it is a problem with the broadband router.
Users with a little network knowledge may know that if a virus appears on the network, sometimes the entire network will be paralyzed. Some network viruses will specifically attack specific ports of broadband routers or continuously send broadcast packets on the network. When encountering such a situation, the broadband router will cause a crash and other problems due to excessive 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:
In the above, we have done some objective analysis on the crash of the broadband router. The article does not favor the users or cover the manufacturers. I just hope that everyone has a correct understanding of the broadband router and hopes that all users can use this better. Products, truly achieve the purpose of high-speed shared Internet access, and truly experience the happy experience of surfing the Internet.
