[Particularly recommended] Typical broadband sharing problems

This article includes common classic problems in broadband sharing. You can take a look at any questions about network sharing!

1. What are the benefits of shared bandwidth?

Now, broadband networks have been activated in many places, and the network speed is greatly improved compared to that of the ordinary MODEM in the past, while the network bandwidth required for browsing web pages and chatting on the Internet is not high, if you just want a computer to use a broadband connection, most of the network bandwidth will be wasted. For a home or small office with multiple computers, if you can share multiple computers with one account to access the Internet at the same time, you can make full use of the network bandwidth so that more people can enjoy the internet. In addition to shared broadband Internet access, multiple computers can also share multimedia files and printers, as well as multiplayer online games.

2. Will Internet sharing by multiple computers increase my network fees?

Most of the current Internet access methods, including adsl modem, CableMODEM, and residential broadband, are generally billed on a hourly basis or monthly basis. Therefore, the amount of data traffic does not affect the network fee. If you only use a computer to browse or chat online, even though the data traffic is small, the Internet access fee you pay is not reduced. In contrast, the Internet shared by multiple computers does not increase your network fees when you get more fun. In a sense, Internet fees are saved. However, pay special attention when using a Broadband Router to share the Internet. Because the Broadband Router has the automatic dialing function, it will always be online as long as it is turned on, disable the vro if you do not have access to the Internet. Otherwise, the network fee overspending will occur.

3. Can different Internet access methods be shared? Can I share a fixed IP address or dynamic IP address?

Technically speaking, various Internet access methods, including common MODEM, ISDN, adsl modem, Cable MODEM, and residential broadband, can be shared by Dynamic IP addresses or fixed IP addresses, the implementation method varies according to the actual situation.

4. Will the network speed slow after multiple computers share the Internet?

The speed of Internet sharing depends on the method you use. The speed of ADSL is generally 512 kbps, and the Cable MODEM and residential broadband are 10 MB, however, the actual network speed is still dependent on the quality of service provided by the supplier. Taking the 512 kbps ADSL Network as an example, when the network speed is ideal, four to eight computers can share the Internet browsing, chatting, and sending and receiving emails. The total bandwidth of these computers is kbps, instead, each computer has a bandwidth of kbps. In addition, the bandwidth is not necessarily evenly distributed to each computer. In this case, if one of the computers uses multi-thread download software (such as network ant financial and FlashGet) to download the firmware, it takes up most of the network bandwidth, leading to slow network speeds of other computers and even the inability to browse webpages. Although Cable MODEM and residential broadband are shared with 10 mbps bandwidth, the Internet access speed between four or eight computers is not slow even when the network speed is ideal.

5. What methods can I use to share broadband Internet access?

Shared bandwidth is mainly divided into software sharing and hardware sharing. Software sharing is to install software such as SyGate and WinGate on computers connected to the Internet, so that the computer can be used as a server and other computers can access the Internet through this machine. This sharing method is easy to implement and is widely used at present. However, it must have a computer with good performance as a server. If the server fails, other computers cannot access the Internet.

Hardware sharing means that computers in the LAN share the Internet through a Broadband Router. It is easier to set up than the sharing software, and no server is required. Any computer can access the Internet independently. In addition, there are corresponding indicators on the Broadband Router, which are simple and intuitive, and users can easily determine the fault location.

6. Is Internet sharing highly demanding for computer configuration?

Using shared software to access the Internet requires a computer as the server. If there are too many computers under load and the data traffic is very large, the host is prone to paralysis. However, for shared Internet access at home, a small number of computers do not require a high configuration of the computer. A computer that uses the celon megamhz processor and MB of memory should be competent. At this time, we need to pay attention to the stability of the server, because once the server fails, other computers will not be able to access the Internet. If you use a Broadband Router or ADSLMODEM with the routing function. It has nothing to do with computer configuration, because a Broadband Router acts as a server, and other computers only need to meet the requirements of broadband Internet access.

7. is shared Internet access in danger of being hacked?

Currently, shared-Access software has powerful functions and generally has firewall functions. When the external network actively connects to the local area network, the local area network only has a valid 1 P address, the external connection is only the server used for Internet sharing. Other internal clients cannot access the server, and thus cannot be intruded. Therefore, compared with independent Internet access by computers, Internet sharing greatly improves computer security. In addition, many broadband routers also have firewall functions, so the external connection is the vro itself, and the vast majority of hacker attacks will no longer work after encountering a vro, in addition, the vro itself is not afraid of being attacked, so it is more secure.

8. Is it costly to purchase hardware devices through Internet sharing?

Currently, the most common solution is to share the Internet with two computers. In this case, the most economical solution is to install two NICs on the computer that serves as the server, one for connecting to the broadband, another network card connects to the network card of another computer through a cross network cable, and then installs the shared Internet software on the server. The price of a common Nic is only about 50 yuan, and the price of the network cable is about 1.2 yuan/meter. Therefore, the cost of purchasing hardware equipment is not high. If the number of computers exceeds two, in addition to the network cards required for each computer, you also need to purchase a hub, switch or Broadband Router. The price of a low-price hub and switch is between-yuan, the price of a Broadband Router is slightly more expensive. The price of a Common product is between and RMB. If possible, you can also purchase second-hand equipment to reduce costs. In general, it is not costly to purchase hardware devices to achieve shared bandwidth, which can be borne by ordinary households. If economic conditions permit, you can select a Broadband Router.

9. Is there a limit on the distance between different computers for Internet access through shared bandwidth?

Shared broadband Internet access is restricted by the distance between computers, depending on the network device you are using. The two computers are directly connected to the Internet through the network adapter, and the distance between them should be less than 100 meters. When using a hub or switch for networking, the distance between the computer and the switch is generally up to 100 meters, depending on the transmission power and the environment, the distance is usually 100 to 3 0 0 meters. When connected via Bluetooth, the valid transmission distance is about 10 meters.

10. Can I use a vswitch to allow multiple computers to access the Internet simultaneously using one account?

Broadband suppliers usually limit that one account can only be assigned one IP address and cannot log on again. Therefore, multiple computers cannot use one account to access the Internet at the same time through a vswitch. In this case, only one computer can be used as a server, or a Broadband Router can be used to share an account to access the Internet.

11. Can I share the Internet via a wireless lan?

Internet sharing is generally implemented through a wired LAN. However, with the increase in the number of computers or the difficulty in wiring, the problem can be solved through a wireless LAN, moreover, wireless LAN is especially suitable for mobile Internet sharing on portable computers. Adsl modem, Cable MODEM, and residential broadband can all be shared over the Internet through a wireless LAN. In addition, wired and wireless networks can be used in combination, providing great flexibility.

12. I want two computers in my house to share the Internet, but I think it is troublesome to install the NIC. Is there a simple method?

If you do not want to install another Nic, you can select a USB Link to connect the two computers and then share the internet. However, you must note that there are two types of USB Link cables. One type only provides the simplest file transmission function and must be implemented using special software, such a line cannot achieve Internet sharing. Another type of USB connector is more expensive than the previous one, but with a dedicated control chip integrated, the driver will be virtualized as a network adapter in the hardware list after installation, there is no difference between the use and configuration of the common Nic, so you can use it to achieve Internet sharing. Compared with the network cable, the disadvantage of the USB Link line is that the connection distance is short, generally not more than 5 meters. Note that the peak data transmission rate of the USB 1.1 interface is 12 Mbps, which is generally equivalent to the 10 M Ethernet speed. If you require high network speed, you can select a USB connector of the USB 1.1 specification. The bandwidth is 40 times that of USB 1.1, and the actual transmission rate is much higher than that of USB.

13. What are the features of software that supports broadband sharing?

There are two main types of software for network sharing: one is proxy server, such as WinGate, and the other is NAT, such as SyGate and ICS. The difference between the two types of software is that the proxy server software sets the host as a proxy server, and requests from other clients to access the network are first sent to the host, then, the host downloads resources from the corresponding website and saves them on the local hard disk, and then sends feedback to the requesting machine. The advantage is that the data can be stored on the local hard disk as a buffer, which can improve access speed and save network bandwidth. The agent server software has powerful control capabilities, but the disadvantage is that the settings are complicated. The advantage of NAT-type network sharing software is that you only need to set the server address to the client's gateway, and the service software completes all the conversions, the client can access the Internet just like directly accessing the Internet without other settings. This proxy method is also called "transparent proxy" because you do not need to configure each network application ". However, it cannot set up a buffer on the hard disk. When multiple machines access the same resource, it has no speed advantage and has weak management and control capabilities on network application software. We can consider which type of software to use as needed. Generally, WinGate can be used when small enterprises/offices need to strictly control the Internet access, for shared Internet access, you can use SyGate or Windows * as the built-in ICS function.

14. Can I share the Internet without a server after using a Broadband Router? If so, what types of Internet access can the Broadband Router share?

A Broadband Router can achieve shared access by multiple users, and all computers in the LAN can access the internet without installing any client software or configuring a proxy server. A Broadband Router is actually equivalent to a host, so it does not need other computers in the LAN as servers. Broadband routers should all support the PPPoE protocol. Therefore, they can connect the Ethernet ports of the adsl modem and Cable MODEM to the Internet, and also support the residential broadband (such as the Netcom broadband) that is directly connected to the Ethernet ).

15. Can I achieve server-free Internet sharing without buying a Broadband Router?

Currently, some adsl modem has the routing function, or you can enable the routing function by setting. In this case, you only need to purchase a switch to connect to the adsl modem, and then
