From the brand point of view, H3C is a world-renowned network equipment manufacturer, and all network products are very good.

1, H3C Compared with ordinary home routers, the router produced by H3C has stronger functions, better data forwarding ability and more stable use. It's enterprise-class equipment.

2.H3C ER3 100 enterprise router is used for export routing of small and medium-sized enterprises and serves as the gateway of the whole enterprise intranet. ER3 100 can solve enterprise problems well through the built-in shaping module. P2P can further limit the excessive use of bandwidth by IM applications such as QQ/MSN through application control module and system module, and improve the work efficiency of employees.

Router selection method

Step 1: Choose a brand.

Home routers have similar functions, but the quality is what you get. Brand is the first factor. Users should pay more attention to the ability and reputation of equipment vendors when choosing router products to form their own networks. These things can be found online.

Another convenient way to look at the quality is to see whether the product has obtained some necessary certifications from a neutral institution, passed the inspection of the regulatory agency and so on. Finally, users need to know the sales volume of this product and how it is well received by users. Everyone is using it, and it sells a lot. Someone has to choose his route.

Step 2: Look at the parameters.

The main parameters involved are: 1. Processor 2. Memory 3. Data throughput 4. Number of tape drives (that is, the maximum number of terminals supporting authentication). Generally speaking, the larger the processor's memory, the better. However, the main frequency of home router processors is between 100M and 200 m, and below 100 m is a lower frequency, and above 200 is a higher frequency, which is generally the configuration of enterprise routers.

Memory: At present, in router memory, 1M to 4M bytes are low, 8M bytes are medium, and 16M bytes or more are large. Data throughput: The router throughput indicates the amount of data that the router can handle per second, which is an intuitive reflection of the router performance.

There are also two important signs: 2.4G-5G, 150M, 300M, 450M, 1200M, 1750M. 2.4G-5G: represents the frequency band of the router. The advantages of 2.4G are long transmission distance and good wall penetration performance. The disadvantage is that there are many interference sources and the speed is slightly lower than 5G. The advantage of 5G is faster speed and less interference. However, the transmission distance is short and the wall penetration performance is weak.

This is a parameter in the router settings. Generally, you can choose to support dual-band 5G wireless WiFi and 2.4G wireless WiFi.

150M, 300M, 450M, 1200M and 1750M represent the maximum supported wireless network speed. For broadband above 1000M, you should choose a router that supports1000 m, that is, you should have 1200M, and.

Step 3: Test the performance.

This is relatively simple, that is, to test the speed of a mobile phone or computer at different network speeds under the router. If possible, find more terminals and test the stable operation rate under the same route. Generally, electronic products now provide a 7-day return package. If it doesn't work, let's change it.
