How to carefully select a Broadband Router

How to select a Broadband Router is a problem for users who want to buy a route. So I studied how to buy a Broadband Router. I will share it with you here. I hope it will be useful to you. The Broadband Router market has become increasingly popular, and more users are using broadband routers to solve the problem of Internet sharing among multiple computers.

Choosing a suitable Broadband Router is an important concern for every user. At present, there are many brands of broadband routers, with different performance and quality. When purchasing a product, users often only pay attention to the price, but do not know much about the features and performance of the Broadband Router. So, how to choose a suitable Broadband Router?

Clarify the most important requirements

Before selecting an edge-connected Broadband Router, you must first understand your needs. This is important for every user. Because the performance and functions of all kinds of broadband routers on the market are different, and their applicability are different. In addition, different users have different needs. If you choose blindly, it is not only a waste of expenditure and maintenance; in addition, it may have a negative impact on Internet performance and enterprise information security.

At present, due to different application environments and application requirements, different users have different requirements for broadband routers. For example, SOHO users hope to be simple, stable, and fast, while some small and medium-sized enterprises and Internet cafes that have not yet established their own internal LAN, they urgently need a mature and secure broadband access method with simple and convenient networking and low costs. Before selecting a Broadband Router, you must clarify several aspects: number of terminals, access type, and environment, such as xDSL, Cable Modem, FTTH, and wireless access; 2. Application business types, such as data, VoIP, video, or hybrid applications; 3. Security requirements, such as address filtering and VPN; 4. Requirements on the router data forwarding rate.

Familiar with vro hardware

A vro acts as a device connecting networks. One function is to connect different networks, and the other is to select a line for information transmission. By selecting smooth and fast routes, You can greatly increase the communication speed, reduce the communication load of the network system, save network system resources, and improve the network system accessibility. The throughput, switching speed, and response time of a Broadband Router are the three most important parameters.

The main hardware of a Broadband Router includes the processor, memory, flash memory, wan interface, and LAN interface. Among them, we can directly see a WAN interface connecting to the Broadband Network Portal) and four interfaces with hub and switch functions. The processor model and frequency, memory and flash size are the key to determining the bandwidth router grade. Broadband routers generally use x86, ARM7, arm9-and MIPS processors. Low-end broadband routers have a frequency of only 33 MHz and a memory of only 4 MB. Such a Broadband Router is suitable for ordinary home users; the processor speed of medium-and high-end broadband routers can reach 100 MHz and the memory should not be less than 8 MB. This is suitable for Internet cafes and small and medium-sized enterprises. When selecting a Broadband Router, you must first look at the hardware. Processors, memory, flash memory, Wan interfaces, and LAN interfaces are all important. The processor determines the performance and speed. Memory and flash memory are the basis for function expansion. Therefore, if the hardware model is good, the quality is high, the router functions are stable, and the scalability is good.

Select the Broadband Router Function

With the continuous development of technology, the functions of broadband routers are constantly expanding. Currently, most of the broadband routers in the market provide VPN, firewall, DMZ, on-demand dialing, support for virtual servers, Dynamic DNS, and other functions. Relevant experts suggested that the investment should be measured according to their own needs. When selecting a vro, you need to understand the various features of the Broadband Router and their application scenarios.

MAC function: at present, most broadband carriers bind MAC addresses with user IDs and IP addresses for Internet authentication. A Broadband Router with the MAC address function can write the MAC address on the NIC, so that the server can pass the MAC address verification during access to obtain the broadband access authentication.

Network Address Translation (NAT): the NAT Function converts the IP addresses allocated to each computer in the LAN to the actual IP addresses of the Internet, in this way, each computer in the internal network can communicate directly with other hosts on the Internet.

Dynamic Host Configuration Protocol DHCP) function: DHCP can automatically allocate IP addresses to customer workstations that log on to the TCP/IP network. It provides secure, reliable, and simple network settings to avoid address conflicts. This is very important for family users.

VPN) function: VPN can use the Internet Public Network to establish a private network with autonomy. A secure VPN includes tunneling, encryption, authentication, access control, and review technology. For enterprise users, this function is very important, which not only saves money, but also ensures enterprise information security.

DMZ function: DMZ is mainly used to reduce the risk of providing services to untrusted customers. DMZ can separate public hosts from local network facilities. Most broadband routers can only enable the DMZ function for a single PC, and some more functional broadband routers can set up multiple PCs to provide the DMZ function. In addition, the Broadband Router also provides plug-and-play uPnP and automatic line sequence recognition functions. In general, the function is directly proportional to the price. When selecting a function, you must decide based on your own needs. You must never choose a function based on the principle of "the more expensive the better" and "the better the brand, to avoid waste or repeated investment. In fact, the most appropriate is the best.

Some details to be aware of when selecting

When selecting a Broadband Router, you need to know the number of users that support access. Theoretically, each access router can allow 253 PCs to share an IP address. But in fact, each IP Address can only support 10 to 30; generally, the upper-grade Access Router can support 100 PCs.

When purchasing a Broadband Router, it depends on whether it can support VDSL wired) and 802.11g wireless) technologies, because these two technologies are likely to become the mainstream in the future. In addition, you must pay attention to the brand when selecting a Broadband Router. Because brand products have commitments in after-sales service and quality assurance, which can greatly reduce users' troubles in use.
