About internet routers and other related issues

If you want to let 10 machines access the Internet, you can set up a fixed 10 IP in the router to access the WAN port, you can access the Internet, and the other 20 machines can access each other as long as they are in the same IP segment as the first 10 machines. The features you mentioned can be perfectly fine. There will be technical support for how to set up the route you procure.

Regarding the ** you said, it depends on whether you are good or almost, ** are not the same.

And you are 2M optical port access, you can use an optical port WAN port routing, industrial-grade to more than 2000 yuan, the rest you can check on the Internet**.

The switch must be wanted, it is impossible for you to use the hub! You don't need to buy a server, you can use the networked machine as a server. It should be done.

1.Several PCs connected to a router belong to the same LAN. So a dormitory connected by a router must belong to the same network.

Moreover, this LAN belongs to the intranet. Due to the limited number of IP addresses, it is estimated that your school can only assign one or two IP addresses (fixed IP addresses of the Internet, provided by the operator), and the IP addresses of the PCs in each dormitory of the school are intranet addresses (and are both intranet addresses, which are local test addresses, and these addresses cannot be used as IP addresses of the Internet).

2.You can use arp-a to look up the IP address of your route, or you can use cmd and then config all to find the IP address of your PC.

3.Any PC has only one IP address, your dormitory is a local area network, and the school is also a local area network. Layer 2 switches are divided into Layer 2 switches and Layer 3 switches, and Layer 2 switches do not generate IP issues.

It's the same as LAN!

ARP-A is the path from the computer you checked to the route, including the IP, and the subnet you said does not need to be set.

Just press the default!

A computer has only one IP, and the switch is equivalent to exchanging data, you can explain that the router adds a few more ports, and the switch will not produce a router!

First of all, arp is the protocol of the network layer, which interprets the IP address as the MAC address, and the arp-a command is to display the ARP cache table, and you should use ipconfig all

Come and check your IP information, I don't know how the above brothers understand ARP, your dormitory is a small LAN, the school is called a large LAN, collectively referred to as the campus network, and the school's IP is equipped with network management.

The summary of the hope is:

Since it starts with 129 and ends with 135 and ends with 135-129=6, the requirement for the subnet mask is to leave at least 8 positions to the power of 2 to him.

So the subnet mask should be pushed forward by 3 bits, which is a 21-bit mask, so the result is.

Network Parameters - WAN Port Settings - Connection Type, PPPOE, Account, Password (Your Own Broadband Account Password).

Set the name and password in the wireless parameters, and the MAC address filter is turned off.

First, press the reset button on your router and set your IP to and press enter in IE.

Then enter the name and password, both are admin, OK, and then select Quick Settings (to set your username and password for Internet access in PPPoE in the WAN), enter them as required.

Finally, set your IP to be automatically acquired and you can surf the Internet.

DHCP server"=> selection"List of clients"After selecting it, you can see how many machines are surfing the Internet.

Enter the router's settings home page, generally the router has written, tp is generally.

Tengda's: It's all by default. The account and password are admin!

Open the routing management interface, there should be a machine IP address to view the router in use, you see, how many are using your router.

Look at what routers to look at! Some routers can be granular enough to instantly monitor which computer is on which one**. It depends on the functionality of the router itself!

Go to the router home page.

Now the DHCP server.

Clients are listed below.

Hitchhiker asks, can you see other machines within the same route through your online neighbors?

As long as your routing is set up to access the Internet, even if the computer turns off the route, it is still dialed by yourself**, that is, you want to go online without turning off the computer, as long as the route and the cat are on, the rest do not need to be set, if there is anything you don't understand, continue to ask questions, I hope to help you.

Doesn't the router have built-in pop dialing?,You use the router as a switch.,Cup,On the back of the router there is the IP address and password of the router login,Log in,Then set the WAN parameters,Fill in the ADSL password,It's really not going to be filled in step by step with the wizard inside,It's you don't understand what I said,The network cable socket of the router is divided into LAN and WAN,WAN is to pick up the cat,LAN to connect to the computer,You should be this connected wrong,

1.When looking for a switch, plug it in directly and use it.

2. Find a route, do not plug in the WAN port, plug in the LAN as above.

Buy another router (or switch),And then use a network cable to connect your router with his router in series.,It's all on the LAN port.,But your network speed is not fast?,If it's too small, I'm afraid you won't be able to play.。

I would like to ask you, did you enter the page of the route through your mobile phone or the computer? If you are entering by mobile phone, I recommend that you use a computer instead to access via a wired connection.

A wireless router is nothing more than doing the following three things:

1. Make sure that the router is connected to the modem or the external network cable normally, and the external network cable should be connected to the WAN port of the router anyway;

2. Enter the routing control page through the wired connection, and in the WAN settings in the network settings, you must choose according to your network mode, for example, if you are an ADSL user, then you can choose the PPPoE connection, and correctly fill in the account and password given to you by the operator;

3. Turn on the DHCP function of the route, which is the switch to automatically obtain the IP (find it in the control page of the route). However, on the basis of this function, all routes are turned on by default.

According to your description, it should be that you set it up incorrectly, so check the network cable and account settings.

First check whether the connection between the wireless router and the cat is normal, whether the cat is working normally (under normal circumstances, there should be three lights on, one is a pow power light, one is an adsl external line light, and one is an internet lan light) If all three lights are on, among which ADSL and so on are flashing non-stop, then there is no problem with the cat.

Secondly, if there is no problem with the cat, then check your wireless router, enter the wireless routing settings to meet, one of which is to select the wireless router transmit power and channel, find him, and then set it according to the manual, if not, let the wireless router reply to the exit setting, and then do not change the channel (automatic) and transmit power (high) when setting.

Finally, if it still doesn't work, please add a detailed description of the problem.

Hope it helps you ......

Step 2: First of all, turn on DHCP, and then go to the wireless part to set up, don't set any security measures. Then use your phone to connect to the wireless router, and if it does, try whether your phone can access the Internet.

Step 3: The above two steps can basically make your computer and mobile phone go online at the same time. This step is mainly to set up security measures. It is to encrypt the wireless part.

Step 4: Save all the settings and restart the router.

It has nothing to do with PPP. Password or something,.

Even if you are not connected to the Internet, the router can also be searched with a mobile phone, try it with a notebook, see if you can get on it, and see if the cat and the router are connected to the network.
