Local connection 10 0Mbps can not access the Internet 100 0Mbps can access the Internet

Broadband speed becomes the solution2008-02-21 Thursday 21:23 Browse the web to see good, suddenly the computer slows down, open the system manager to see, there are a lot of processes that have not been seen before, some look like viruses, such as . Terminating the process didn't work, it would automatically turn on after termination, so I had to turn off the modem.

Immediately the process does not move, and it can be terminated directly, guessing that it may be a hacker. When I turned on the broadband again, the speed of the Internet connection changed, and I couldn't fully display many web pages. I searched the Internet and finally found a solution:

Right-click"My computer", select"Management"and double-click on the right"System tools", and then click"Device Manager"to see the hardware devices on the unit, one of which is there"Network adapter", find the network card of the machine and double-click it, and the properties dialog box of the network card will pop up. Superior --- left"attributes"There is one"speed & duplex"This is the working mode of the network card selection project, when selected, there will be a hitter on the right"value"You can choose the 100M working mode, generally choose Auto or 100BaseTX Full Duplex, click OK and reconnect to the broadband.

If there is a problem with the crystal head of the place where you surf the Internet, if it still doesn't work to redo it, you check the port of the switch at home, or change the port.

10m and 100m are just the maximum speed of the network card.

If you plug in the network cable repeatedly, it will be normal, and you will know that it is a contact problem.

The contact problem between the crystal head and the network card.,I want to say it's the crystal head problem.。

You've replaced three of them, so it's only a problem with the network card, check it carefully.

The metal shrapnel inside the network card, or try it again regardless of the 3721.

It's better to give the most rustic speech, hehe.

Both of your problems are caused by the same cause.

You've ruled out the settings of port speed matching and network cable issues, so observe whether one of the pins in the Ethernet port of the laptop is deformed or elastic enough to cause poor contact?

You have borrowed someone else's laptop to test on the network cable at home, if you find that other people's use is normal, then it must be a problem with the laptop network card, please find the notebook after-sales maintenance. Treat the domestic after-sales service, please be tougher, this is obviously the problem of the book, you only need to be responsible for judging (in fact, the judgment is the problem of after-sales) and do not need to find out the root cause, do you think that every user must be proficient enough to be able to deal with the fault by themselves? So what else do you have to do after the sale?

In addition, you said that the 10m half-duplex can be used normally when you get it to the service department, so can it be used normally at other speeds in the after-sales service? Because it can only be used in 10m half-duplex after the sale, then it is certain that the problem with the notebook is also certain.

Yours is a LAN, normally there are two network connection icons, one is a LAN and an external network. Your intranet is now as you say there is no problem. Therefore, it can only be a problem with the external network.

Since it is a local area network, you can see if the Internet access of other computers is normal, and if the Internet access of other computers is normal, it means that your computer settings are wrong. You can look for a post on LAN settings online. There are very detailed instructions above, so I won't write them here.

Hope it helps.

After reading your long description, you try this: open the device manager, find your network card, open the properties of the network card, click on the "Advanced" column, and then there is a selection box to select the working mode of the network card, you select "100basetx full" full duplex, and then OK, "OK". Then turn everything off, reopen the broadband dialer program, dial up the Internet, and at this point it is, this is normal!

I'm sure it'll be soon!

I want to know if the current mode of your network card is 100 full duplex or what, you had better set the network card to automatic mode, do not choose 10 or 100, and then you check whether there is a Trojan or virus in your computer Generally this situation is caused by the setting of the network card or a virus, if you believe me, you redo the crystal head, and then see if the computer will be normal in this way.

It's okay to get somewhere else?

That's the problem of telecom broadband on your side.

If the LAN is fine, look for telecommunications.

There is a setting for the network card, which can be adjusted to 10 100m adaptive.

That is there a problem with your computer's network card!

Yes, it should be a broadband issue.

Hit ** to 10000. Call the staff to come and help you get it!

This refers to the maximum access speed of the computer network card, and your network card is 10 megabytes, so it will not delay your use.

Obviously, the operator does limit the bandwidth setting! Something that needs to be paid to solve, hehe!

First of all, can you use the Internet at 10Mbps at the beginning?

If you can access the Internet from 10Mbps to 100Mbps later, you won't be able to access the Internet, because Netcom has set a rate of 10Mbps. When you change to 100mbps, it's 10 on one end and 100 on the otherThey can't communicate with each other, so you can either change your own network card or negotiate with Netcom personnel to see if Netcom can change the rate.

If you can't access the Internet at 10Mbps, the possible reason is that the interface of the transit device (router) you use does not match the rate supported by your network card attributes or the rate supported by Netcom.

You said that you can go to other people's routers, I want to ask, other people's homes also use yes Netcom? If so, you can borrow someone else's router and put it in your house to see if it's OK

If the dial-up number can be turned on, but the route change cannot be accessed, it means that your router settings are incorrect.

If you're going to auto-dial through your router, find someone familiar with you to set it up for you.

It has nothing to do with the local connection 10m or 100m.

It's very likely that the router is broken, or you can create a new connection and try again.

In full-duplex mode, the 8 wires must be connected to the corresponding line sequence position of the crystal head; In half-duplex mode, only 4 wires are required.

In full-duplex mode, the maximum speed of the network cable can reach more than 100 megabytes; In half-duplex mode, the speed that the network cable can achieve is usually about 10 megabytes. The network cable in full-duplex mode can work in both full-duplex mode and half-duplex mode; However, the network cable in half-duplex mode cannot work in full-duplex mode.

If one or more wires in a full-duplex network cable are short-circuited or poorly contacted, such as a blue or brown line group, then changing the network card to half-duplex mode can avoid using the problematic blue or brown wire group, so as to solve the network connection instability, disconnection and other faults.

You can set full-duplex or half-duplex mode in NIC properties.

If it is useless or cannot be changed, there is a problem with the network cable or the crystal head is not done.

You set the router from the new one, or restart it, there is a small hole in the router, hold it down with a pin for 3 seconds, and try it.

I guess the link speed you'll see in Task Manager is 10Mbps

It's a file song.,This can be set.,If there's only a 10m option.,It's your network card that the eggplant bureau is very old and stupid.,It's best to change it.,Now it's all a thousand m network card.。

If the network transmission speed is 10m, that's very good, and now the most used is 1m.

The 10m you see,It's when you see the connection of two small electric ants on the computer desktop,When you see the connection of two small electric worms to raise the brain,10m locally, right??

This is the adaptive speed of your network card, not the speed of your network!

And the home network generally only has dates.

If it's always been like this, there are several possibilities:

1. It may be because the configuration of your machine is not good (you should consider upgrading the hardware);

2. It may be that the bandwidth of your bridge access is not enough and the Internet speed is slow. If it's been like this recently:

If it's something like this recently, it could be:

1. It may be poisoned, you can find suspicious things in the "Task Manager" of Minsocks; Or use the "Internet Assistant" to analyze and process;

2. It may be that the free space of your hard disk is not enough to leak and bend, and you should clean up the disk;

3. It may be that you have too many "temporary Internet files", consider cleaning up;

4. Is the webpage you are opening too big? You can just open the text;

In addition, some malicious** may also affect the speed of opening a web page.

Clean up your computer with a tool such as Internet Assistant or Optimizer.

The rate of the connection is 10 MB per second, 1 byte = 8 bits, that is, the maximum data transfer rate of the current connection is 10 8=

Generally, the current network service with card rate is 10 Lao Lu 100M adaptive network card, or 1Gbps high-speed network card, 10Mbps speed calendar return rate is very slow, this problem may be due to the network card itself is too low-end does not support high-speed network, or it may be due to configuration problems such as working mode, driver and other problems.

It may also be that the device that accesses the network does not support the higher rate, such as the switch or router does not support it (it may also be that the network device configuration is not enabled and the 10 100m adaptive mode is not enabled).
