Router Panic reason

Often in the Internet to see many netizens in the purchase of broadband routers, in the use of the process encountered a frequent crash-line problem, to bring a lot of inconvenience to netizens, so that some products are not worthless by netizens. Today, the author makes an objective analysis of the problem of broadband router deadlock, and see what causes these problems.

1, from the session said with the number of machines caused by the fall of the line crash

Many manufacturers in the promotion of their own broadband router products generally refer to a can be connected with the number of machines, most manufacturers will say that their four-port broadband router can bring 10-20 units. However, some users in the use of the process, with machine 10 will appear after the crash line situation, in the purchase process, we first need to analyze their own broadband router and the number of their own machine and the application is matched. Sometimes because of their actual environment is not suitable for the use of purchased products, there will be broadband routers can not afford the network load phenomenon, and caused the problem of the crash line.

From a technical standpoint, we usually talk about product performance with NetIQ Chariot software testing (smartbit expensive), with one session (Chinese name conversation) that can illustrate some of the problems. In the IT168 evaluation of the four-port broadband routers, generally in the test will use this session option, throughput and processing performance We do not talk about, only to talk about with the number of machines directly related to this option. Typically, broadband routes with better performance can establish 300 pairs of sessions at the same time. And almost only 200 pairs of sessions can be reached.

We assume that the broadband router with 10 units (here is the intranet to the external network connection, the connection between the intranet is by the broadband router Exchange port, basically can close to the nominal value of hundred), when the computer needs to access the Web page, Enter a domain name in the browser after the broadband router will initiate a session request, the Web server received this request will have a response back to the broadband router, then will establish a session. If the 10 machines at the same time open 10 pages, plus QQ, MSN and download tools, and so on, each machine to establish a pair session. 10 machines is pair session.

Under this load, the general broadband router should be able to operate normally, but 20 machines, I believe that the application of more than one network, broadband routers will be machine. From this example we can see that in some network applications and machines in many scenarios, the home Class 4-port broadband router is simply not applicable. And some users buy home with 4-port broadband router to do small internet cafes shared gateway, I see the crash line is not surprising.

To sum up, we buy a broadband router must be based on their own number of machines and demand for comprehensive consideration, do not engage in a small horse cart, causing unnecessary trouble and economic losses.

2, users reflect the crash-line problem most of the product is the worst?

BBS on the Internet can often see that some products have a lot of users in the process of talking about using the crash line problem, and some products do not see such comments. Can these comments indicate that the product is really the worst? I have not used a broadband router before, so mistakenly think that broadband routers do have a lot of product defects, once accidentally and a Beijing sales of broadband router dealers talk about this problem, he said the fact is not the case in fact. From an objective point of view, any manufacturer can not achieve 0% of the defective rate, the production of each product is qualified.

Readers may ask, does this defect rate have anything to do with the broadband router crash? Here we give you an example to explain this problem.

This assumes that there is a product and B products, two products are also one of the extremely defective rate. A products in the market sales of 100,000 units, and B products only sold in the market 10,000 units, according to the ratio of one out of 10,000 to analysis, a product will have 10 products may have problems, and B products may only have a product problems. At this point, we can find that the 10 users who use a product are dissatisfied with the product, and B products will only have one user dissatisfied with their products.

From the above analysis we can see that many of the market in the use of broadband routers in the process of using the crash-line problem, this may be due to the production process of individual products caused by problems, but this is not enough to show that this model of the product will be frozen off the line problem. Since I later use the broadband router products, found that its products are still very stable, and did not appear the Netizen mentioned the crash line problem, so I personally feel that the comments of these netizens is only a case, and does not represent a general problem.

Of course, from the user's point of view, we hope that manufacturers to produce broadband routers can allow users to ease the use, but some manufacturers of products are indeed because the quality of the product is not qualified to cause the crash line, is not included in the. Therefore, some products in the online evaluation does not mean that all the products of broadband routers is a problem, we can not be a pole overturned a boat people.

3, the user technical level is limited, the establishment improper causes the deadlock to drop the line question

We know that in the use of broadband router products, the technical level is uneven, many users for broadband router products and technology is only inkling, for most broadband router settings are not very understanding. The dealer also told me that a lot of users will buy the broadband router back, will not set, and he used to a few minutes to fix things. Therefore, sometimes encountered improper setting caused the broadband router to fall off the line of the problem.

When encountering such problems, we hope that users can also face the correct attitude, carefully look at the product use instructions, and after-sales service personnel to communicate in a timely manner in order to accurately determine the reason for the crash line problem. If the quality of the product is a problem, manufacturers will also give users a good solution to the problem. If the manufacturers ignore the phenomenon, we will again through some media to reflect the problem, arouse the attention of manufacturers to take a positive attitude towards. The abuse on the Internet, I think is a kind of irrational performance, ultimately will not solve practical problems.

4, access line quality is poor, virus problems caused by the crash-line problem majority

In addition to the improper use of the user settings will cause the broadband router operation is not normal, access to poor quality, virus and other problems are also caused by broadband routers off the line is an important factor. From my own experience in the process of broadband installation found that China's Internet access lines have a big problem. For example, ADSL line, the technology itself for the telephone line quality requirements are very high, while in some old residential buildings, the use of older telephone lines, line quality itself for the basic function of the call is only barely cope with, in this environment, how to ensure the normal operation of ADSL line?

such as the Great Wall broadband, my own home installed is the Great Wall broadband, in order to save the cost, the long width in the building wiring uses a twisted pair of wires to divide two to connect two households respectively, this kind of wiring is one kind of inferior wiring project, the line eight pairs of cables are simultaneously in use, greatly increases the possibility which the signal interferes. In such a broadband line, sometimes will also cause frequent drop line, after the line, users can not find the reason, it may be unclear to say is the problem of broadband routers.

Users with a bit of network knowledge may know that if a virus in the network sometimes causes the entire network to be paralyzed, some network viruses specifically attack the specific port of the broadband router or send broadcast packets continuously in the network. When this happens, the broadband router will be overloaded and caused by the crash line and so on. After the analysis above, we recommend that users should carefully check the problem of whether the computer is virus or not.

Summarize:

Above we have done some objective analysis for the broadband router's dead line, the article does not favour the user, also do not shield the manufacturer, just hope that we all in the broadband router has a correct understanding, I hope all users can better use this kind of products, real high-speed sharing the purpose of the Internet.
