What factors to consider in determining the router

Essential factors to consider when choosing a router:

1. Optimality: The data being transmitted takes the shortest time from the current node to the destination node.

2. Fairness: Load balance each node in the network.

The traffic is uniform. The users of network resources are treated equally, which not only allows the priority of transmission, but also prevents the users with priority from monopolizing the network.

3. Simplicity: The routing algorithm itself will not increase the overhead of the network too much, that is, the routing algorithm should be simple and easy to implement.

4. Adaptability: It can adapt to changes in the traffic volume and topological state of the network.

5. Stability: When a link or node in the network fails, it will not be affected by the network topology.

The change affects the normal arrival of packets at the destination node, and the delay of the changed route is not much.

A router is a router that connects various LANs and WANs on the Internet.

It will automatically select and set the route according to the situation of the channel, and send the signal in the order of the best path. Routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. Routers are divided into local routers and remote routers, and local routers are used to connect network transmission media, such as optical fiber and coaxial cable.

twisted pair; The remote router is used to connect the remote transmission medium, and requires the corresponding equipment, such as the ** line, to be equipped with a modem.

Wireless should be through wireless receivers and transmitters.

It is a standard protocol of 300m or more!! It is an agreement under 300m! The penetration ability only depends on the db size of the antenna!

Household use is generally good to choose a good brand. If there is no inbound transmission! Basic 150's on it!

Because the 150 antenna and the 300m antenna are the same db, it is recommended for field testing!! In terms of wireless, the parameters can't control the environment!!

If you use it at home, it generally depends on whether the stability is good or not.

Therefore, TP-Link is generally used.

There is also a need to look at the bandwidth, 150M or 300M.

Then there is the signal strength, whether the signal standard is supported.

Because at present, this standard has the strongest signal penetration!

The things that we usually need to pay attention to when choosing a router are:

1.**The more expensive the cost performance and quality are better than the average, when it is not all**The more expensive it is a little easier to use.

This varies from person to person.

2.Whether the frequency band or 5G is used depends on the family's house.

This year, router technology has developed very fast, most of the products used to be products in the frequency band, a small number of products in the 5GHz frequency band, and now products that support dual-band differential calendar have sprung up. The transmission rate has also increased from only 300m to 300m-2200m now! It is recommended that when purchasing, it is best to choose a router that supports both mainstream wireless standards and 11N, that is, and 5GHz.

The 5GHz rate is high, and the interference is small, but the relative wavelength is short, and the wall penetration force is poor. Although the rate is not high, its wavelength is longer and has a good ability to penetrate walls. These two frequency bands are used at the same time, and with a good antenna layout, Maqingchai can provide better WiFi coverage.

3.View product outsourced late molding, appearance, and accessories.

For example, whether there is 3C certification.

Logo, whether the appearance is damaged, whether there is an instruction manual, warranty card, network cable and installation CD, etc.

1. The size of the bandwidth of the router: the bandwidth of the router is theoretically as large as possible, but when choosing, you should still choose the router based on your actual needs;

2. The type of wireless switch of the router: some wireless routers have a wireless switch, and you can turn on or off the wireless wireless directly with this switch, and choose the router according to the actual situation;

3. The wireless signal strength of the router: if the distance is far away or there are many obstacles, you should choose a router with more antennas;

4. Whether the router has WDS function: Some wireless routers do not support wireless bridging function, if there is such a need, you should pay attention to whether the selected router supports WDS function;

4. The WDS function of the router: Some wireless Xiaola routers do not support the wireless bridging function, if there is such a need, you should pay attention to whether the selected router has the WDS function.

5. Whether the Qingqiao router has a signal enhancement function.

It is best to have dual bands separated, power size, support multiple devices, wifi6.

In most cases, it is connected to the home broadband interface or optical modem, and the wifi transmission point is added to the home broadband.

The router is a traveler address translation route**, and there is only one IP in the normal strip wide judgment town shelter belt, and only one device can be used for direct connection, and more devices can be accessed through router conversion when it is not enough.

The router is most suitable for expanding the network, and it is suitable to add router relays in places where the wifi network is not covered.

1. Enter the router management interface.

The first time you enter the router management interface (you can also click the "Setup Wizard" option in the left menu in the main router management interface), a "Setup Wizard" interface will pop up, click the "Next" button;

2. WAN port setting.

In the pop-up "WAN Port Settings" interface, users need to choose the Internet access mode according to the actual situation, which is an extremely important step.

Since you generally use the monthly ADSL broadband service, you need to select PPPoE in the drop-down menu of "WAN Port Connection Type", and enter the corresponding username and password in the "Internet ID" and "Internet Password" dialog boxes, respectively. Since ADSL can automatically assign IP addresses and DNS servers, neither of these is filled. Directly in the corresponding connection mode, select the "automatic connection" item, so that you can connect to the network as soon as you turn on the computer, which greatly increases office efficiency.

It should be noted here that if you are not a monthly subscriber, we recommend that you use "manual connection" to avoid overspending on Internet fees. After the settings are complete, click the "Save" button to save the settings.

3. Set the DHCP function of the router.

DHCP is a special feature of the router, with DHCP we can avoid errors caused by manually setting IP addresses and subnet masks, and also avoid address conflicts caused by assigning an IP address to multiple workstations. The use of DHCP not only greatly reduces the time spent on configuring or reconfiguring workstations in the network, but also provides the flexibility to set the lease period of the address by setting up the DHCP server.

Click the DHCP Server option on the left side of the page, and click Enable in the DHCP Settings window. The "Address Pool Start Address" and "Address Pool End Address" options are and respectively, note that x cannot be , y cannot be 255), here we can arbitrarily enter the 4th address segment of the IP address. Click the "Save" button when you're done setting it up.

After the above settings, as long as you open any computer in the local area network and start the Internet Explorer, you can share resources and surf the Internet.

You can choose the smart router's.

The advantages of smart wireless routers over ordinary routers are as follows:

1.Intelligent control of bandwidth When we have 10M bandwidth and 10 people surf the Internet at the same time, each of us gets 1M bandwidth; But when we have 5 people surfing the Internet, if you are using a non-smart wireless router, each of the 5 of us still only has 1m of bandwidth, and the smart wireless router is different, it will distribute the bandwidth evenly according to the number of people who go online, that is to say, each of us gets 2m of bandwidth.

2.Intelligently control the number of people who use the Internet to limit the bandwidth of each person Recently, I saw a smart wireless router with a screen display, which can see the number of Internet users at any time, and can control the Internet bandwidth of each person and limit their Internet access at any time.

3.Intelligently control the Internet time You can set the Internet time at will, for example, parents set two hours of Internet time for their children, and after two hours, the child's network will be automatically disconnected.

The premise is that a broadband network needs to be installed and multiple devices are required to use wireless wifi to access the Internet.

The wireless router also needs to be set up to access the Internet before it can use WiFi.

1. The bus of the broadband network is connected to the WAN port of the router, and the LAN port of the router is connected to the computer.

2. After starting the device, open the browser and enter it in the address bar to enter the wireless router settings interface. (If you can't get in, please look at the nameplate at the bottom of the router or the router instruction manual, the default settings of different models of routers are different.) ）

3. An account and password to log in to the router appear in the settings interface, enter the default account and password admin, or refer to the manual;

4. After successful login, select the interface of the setup wizard, which will automatically pop up by default;

5. After selecting the setup wizard, a window will pop up to explain that you can set the basic parameters of the router through the wizard, and click Next directly;

6. Set up step by step according to the setup wizard, select the Internet mode, usually ADSL users choose the first PPPoE, if you use other network service providers, select the following two according to the actual situation, if you don't know how to choose, directly select the first item to automatically select, convenient for novice operations, click next after selection;

7. Enter the account and password applied for from the network service provider, and go directly to the next step after the input is completed;

8. Set the wifi password, try to make the alphanumeric combination more complicated, and it is not easy to be rubbed off the network.

9. After entering correctly, it will prompt whether to restart the router, select Yes to confirm the restart of the router, and you can access the Internet normally after restarting the router.
