How does a router hub share Internet access?

First of all, you need to set up your router:

After <> set up the router, follow the figure below to connect the line.

The way to access the Internet is to use the ADSL modem, connect the WAN of the router with the ADSL modem, and then connect the 3 LAN interfaces of the router to 3 computers. Use one of the computers to set up the router dial-up (PPPoe mode), use the remaining LAN port of the router to connect to the hub (whether this connection is made with crossed wires or parallel wires), and then connect the other computers to the hub interface.

Answer: After using the router, there is no need to set up a dial-up connection on the computer, just enter the router setup wizard to enter the broadband and password to save (it is best to set it to your own connection), so that you don't have to dial by yourself is a routing dial-up.

The hub (now all use switches, parallel wires are connected) should generally be connected with crosswires, if not, use parallel wires.

The IP of the router is the default:

Our DNS:

Is DHCP on the router? Answer: It is recommended to enable DHCP, so that the computer does not need to set the IP (you can also set the IP outside the dynamic IP pool).

Does the router connect the hub with crossover or parallel wires?

Answer: In the past, the hub connected to the hub almost always used a crossover line (even the route has not been used, it is recommended to use a switch (parallel line) for much faster speed).

Is the computer connected to the hub connected to the Internet using crossed or parallel lines? Answer: Parallel lines.

How do I set up my router? Answer: Said above. You can refer to the manual, and you will read it.

How is the computer connected to the router set up? How do I set up the computer connected to the hub? Answer: Even the two are the same, but you don't need to set it up (to ensure that the network can be connected).

The router and hub are connected with a crossover cable, but devices now support automatic flip jumpers.

The IP settings of the machines connected to the hub are the same as those of the machines connected under the LAN port of the router, and they are in the same network segment.

There are three reasons why a computer connected to the hub may not be able to access the Internet

1. The hub itself is faulty.

The fault symptom is that the computers on the hub cannot ping each other, let alone the router. Therefore, the obstacle can only affect all computers connected to the hub.

2. Cascading faults.

For example, the cascading jumper between the router and the hub uses an incorrect line sequence, or the jumper connectivity fails, or the cascade port does not carry the correct code. The symptom is that the computers on the hub can ping to each other, but not to the router. However, Internet access for computers connected directly to the router's LAN port will not be affected.

3. Broadband router failure.

If it is a LAN port failure, the result will be similar to a cascading failure; If it is a routing failure, the result will be that none of the computers in the network can access the Internet, whether connected to the LAN port of the fiber router or connected to the hub.

From the fault phenomenon, the computer connected to the hub can neither ping the router nor other computers, and it is preliminarily concluded that it should be a hub failure.

One ADSL is connected to the router and the other ADSL is connected to another wireless router; Then both routers are connected to the hub, and you're good to go.

It should be noted that: 1. The network segments behind the two routers must be different, for example, one is itself and is responsible for the routing service of the network segment; The other is that the service responsible for the network segment is called; The default IP of the router must be changed to one; It is recommended to change the wired router;

2. The DHCP service on one router must be turned off, otherwise both routers will rush to assign other people's IPs, and the entire network and router will not work normally. It is recommended to turn on the wireless router and turn off the IP address of the wired router;

3. If you change the wired router to 0 network segment, then all desktops are connected to the 0 network segment of the wired router, and all wireless notebooks use 1 network segment, even if they are plugged into the same hub, they will not interfere with each other;

4. The network card of each computer can be tied to two IP addresses and two gateways, which is called load balancing, but it may cause QQ to be disconnected, if this happens, you don't need to remove the double IP, you only need to remove a gateway and keep a gateway.

Routers and hubs are both used for network offloading and are the basic equipment of the local area network.

The signal amplification function of the hub is more effective than that of ordinary routers. Therefore, hubs are generally used in Internet cafes, which can divert a lot of resources and connect multiple computers.

The router is usually used at home and connected to 2 or 3 computers. Generally, it is the LAN interface and WAN interface.

A wireless router, as the name suggests, is a router that can receive and offload the network without the need for network cables. A computer is required to turn on a wireless network, and the router settings are similar.

The hub you are talking about should be a broadband cat, and you need to connect and set up a wireless router correctly.

1.The router is a device that sets up a LAN to achieve network sharing, and the general connection and setting methods are as follows: connect the network cable out of the broadband cat to the WAN port of the router, connect each computer to the LAN port of the router, and the IP address of the computer network card is set to be automatically obtained, enter it in the address bar of the computer browser, and specifically check the network parameters obtained by your computer network card, and log in through the IP address of the gateway) Log in to the router, and the general user name and password are admin, Select the WAN port settings, and set your broadband account and password to the PPPoE mode.

2.If the laptop uses wireless Internet access, the operation is as follows: right-click the online neighbor - properties - right-click the wireless network connection - view the available wireless network, click your wireless network name in the searched wireless network - connection, and enter your wireless network key for verification, after passing the verification, you can connect to the wireless router to surf the Internet normally, at this time the laptop does not need to use broadband connection; If it is a mobile phone wifi, the same as above, it is also a search for wireless signals and enter the wireless network key to connect and you can use it.
