Detects what commands are not common between the computer and the router

The ping command is generally used to check the connectivity of the network layer. In the local area network, how to detect whether a computer and the router are connected normally, you can use the ping command to detect.

The following are the methods and steps on how to use the ping command to check whether the computer and router are connected.

1. In the lower left corner of the computer, click "Start", as shown below

3. In the pop-up command prompt, type: ping

4. If the computer and the router are connected, the reply from will be returned, as shown below: 5. In the pop-up command prompt, type: ping

6. If the computer and the router are not connected, the following information will be returned, as shown in the following figure:

First determine what address your router is? Generally, TP's are foreign, some brands may be or really forgot the address, you can find your manual first to see what the default address is? Then press a button on the router to restore the factory settings, and then use "ping router address -t" to determine whether it works.

Ping is this.

Ping -t is always displayed, if you want to turn it off, use Ctrl+C

In the start-run basket type: ping or.

It would be nice to ping the router address.

Added: ping -t

There is generally an IP address on the back of the router, enter the IP address in the IE address bar, and the login interface will pop up, if you can pop up the login interface, it means that it is connected to the router.

Use the ping command.

Set the IP address of the computer to be on the same network segment as the router, and then ping the IP address of the router.

See if the light of the router is flashing.,Try a program.,If it's flashing fast.,Then there's a link.。

The mobile phone wifi is turned on to find your routing name, and after connecting, try to surf the Internet in the mobile browser

A traceRT is a traceroute utility that determines the path taken by an IP packet to reach its destination.

Use the tracert command to trace.

telnet to your Huawei router, and see if the router can ping the B network segment. If you can ping, write a static route on the router or the host that is connected to the destination network segment through your gateway 200 to see if you can go to the B network segment.

If the static route is invalid, then there is a policy on the core 3 layer, which is what the following netizens said. Except for the CIDR block, no other CIDR block B can be accessed.

Route A is set to an address pool, and Route B is set to dynamic connection in the Connection Mode column.

Explain that your router is set up with a secondary route.

The ACL policy on the B and A segments allows only the IP addresses of the A segment to be accessed.

So your secondary route segment is unreachable to B.

If the two computers are not in the same network segment, they can't ping, 1Both computers are turned on and network sharing resources are set up.

2.Both sides of the computer were added"microsoft"Network File and Print Sharing Services3Both parties have set the IP addresses correctly and must be in one network segment.

4.Firewalls are turned off in both computers, or there is no policy in the firewall policy to block neighbor access.

I've synthesized the answers from the above, so let's try it comprehensively.

Yours is indeed a problem with the network card, although it doesn't show that the network is disconnected or something

Solution, you can try to remove the network card and then reinstall it, if it still doesn't work, change to a new network card, it's not very expensive, only about 25 yuan. Or you can use someone else's network card to do a test to find out what the problem is.

In the IP address, the gateway is the route, and the IP address is the route, for example, the route is your gateway.

Actually, there's another way to get the IP address automatically if it's a 2000 or XP system. and gateways. If you get it to run --- cmd via in the start menu

In the DOS interface, type ipconfig all to find out the obtained IP address and gateway. You can fill it in manually.

The network card problem is too obvious, just change to a new network card. I've seen too many of these kinds of problems.

The IP address of the router interface connecting the switch is in the same network segment as the IP address of the address pool assigned by DHCP, and the router in the IP address pool in the DHCP server must be the IP address of this interface of the router. Of course, the IP address of the DHCP server is also in the same network segment. Then, all computer interfaces are set to automatically get an IP address.

If the external network is directly connected to another interface of the router, you only need to configure the IP address of a different network segment on the other interface, and no other configuration is required.
