Problems with the router, understand the person who came in and said

It is estimated that the router is not set up correctly, please refer to the connection below to re-set your router, it should be able to solve it.

The main thing is the Mac settings.

If there is a problem with the network cable or router, take the network cable to use it for a day, and then test it with someone else's router, and then replace that part if it is broken, and the router can find a broadband connection for you to change it for free, and the network cable will be bought by yourself, one dollar and one meter.

Looking at your problem, I suspect it's a hardware issue that might be routed. First of all, see if the routing lights are flashing normally after the disconnection is disconnected, including the power lights. The WAN entrance light is not on.

Whether it generates a lot of heat and dissipates heat poorly. If it is normal, the DOS pings the routing address, but it can't be seen. If so, troubleshoot intranet issues.

Then the route is entered, and the WAN port dial-up is not dialed up. View route logs. Or the problem with cats.

Troubleshoot step by step.

It's very simple, it may be that you set the ppoe and password in the router when you didn't choose the choice in the router There are several forms of Internet access, such as connecting when accessing the network, and the network will be automatically disconnected when there is no network access, and you choose to access the connection all the time.

It's the router that's broken, and the normal use is 1236 four (4578 useless), uplink use 2 and downlink use 2, and the rest are useless.

There are two ways to use network cables, one is a crossed line, and the other is a parallel line.

The practice of crossing the line is: one end adopts the 568A standard, and the other end uses the 568B standard parallel line: both ends are the same 568A standard or 568B standard, (generally the practice of 568B parallel lines is used).

568A Standard: Green White, Green, Orange White, Blue, Blue White, Orange, Brown White, Brown 568B Standard: Orange White, Orange, Green White, Blue, Blue White, Green, Brown White, Brown.

You can notice that the difference between the two methods is that the orange and green colors are swapped.

If the two parties to the connection are not equal, use parallel wires, such as a computer connected to a router or switch.

Use crosswires if the two connected devices are equal, such as a PC to a PC.

I hope mine can help you a little.

The above is just a regular connection!

Because the general network cable is only used in others, even if it is not connected, it can be used! ~

Use the ranking method. When there is a problem with surfing the Internet, try the following ranking to determine which setting is wrong.

1. Broadband in the form of network cable to home, optical fiber, etc.

If the routing fails to access the Internet or is often disconnected, do not use the router first, and connect the network cable (main line) directly to the network card of the computer, establish a dial-up mode on the desktop, and directly dial-up to connect to the Internet. See if the problem of Internet access will appear again, if it also appears, it means that it is a problem with the broadband line, and it has nothing to do with the router and computer network card. If everything is fine, then there is a problem with the router.

2, ** line into the home, the front end is equipped with a modem (cat) is also not routed, the cat out of the network cable directly connected to the computer, the system with dial-up Internet, see if there will be a problem. If nothing goes wrong, it's a problem with the Lupi Guard. If the problem is still there, it is the cat or the broadband line by the problem, conditionally borrow a cat to replace it, and then further distinguish whether it is the cat or the broadband line.

Reset the router and set it up again.

1. Connect the line between the network cable, the router and the computer, and start the computer and the router equipment;

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 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.

What is the problem? The connection is not good, or the Internet is slow.

The main reasons for the difference are as follows:

Due to the current widespread use of wireless routers, only wireless routers are analyzed here).

1. Speed difference.

Wireless routers follow protocol groups, which come in multiple versions and have a maximum bandwidth of up to 1GB.

Wireless transmission speeds range from 25MB to 1GB, and the speeds of commonly used wireless routers are 150MB, 300MB, 600MB, and 1GB.

**Varies widely.

2. The difference between brand and stability.

You get what you pay for, and although a good brand is more expensive, it is more stable.

If it is an enterprise-level router, the work is more stable, and the ** will naturally go up.

3. Functional differences.

According to the functional classification, wireless routers can be divided into: smart routers and ordinary wireless routers.

Smart routers are high-end configurations in terms of hardware configuration, and the hardware cost is high.

Some smart routers also come with their own hard drives. For example, Xiaomi routers come with 1TB hard drives.

Smart routers can install plug-ins, realize custom functions, can be used as a home intelligent control center, smart routers have high hardware and software costs, and its ** often multiplies.

Ordinary wireless routers also have some differences in function, some routers can adjust the wireless transmission power, and some have a true relay function. So there's a slight difference as well.

To sum up, the difference between an ordinary wireless router and a smart router with a mechanical hard disk is about 600 yuan.

The difference is even greater when compared to an enterprise-class wireless router**.

Personally, I recommend buying tplink.

Basically, there is not much difference, the quality of the big brand is stable, and the small brand depends on the luck. I feel relieved that I will be renewed for a year.

I've used both of them and it doesn't feel the difference.
