Why is my wifi only sent, not received, always 0

If you only send but not receive, the system cannot access the network.

There are several reasons why you can't connect to the internet when you connect to wifi

1. The wifi itself is a problem, and the wifi may not be connected normally, resulting in the inability to access the Internet.

2. Router problems, the router may be overheated or damaged.

3. Broadband arrears may lead to inability to access the Internet.

4. The wifi name contains Chinese, which causes some computers to be unable to connect to the Internet.

5. Computer system problems, there may be problems with the system, resulting in connecting to wifi but unable to access the Internet.

Suggested workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet, and rule out the wifi itself.

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband, such as arrears, recharge the broadband, and then dial up the connection.

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting.

5. If the above reasons are ruled out, it is likely to be a computer system problem for a long time, and it is recommended to restore the factory settings. See if that solves the problem.

To see if you are really assigned an IP address by the router, you type "cmd" in the run, then press enter, and then enter: "ipconfig" After entering, you see if the IP address is like this, if so, it means that the IP is assigned. You just ping a ** again, the command is:

ping** can be replaced)", see if you can ping out, if you can, then no problem.

If there is no IP address assignment, then there is something wrong with your wireless card settings and you may not actually be logged into the router. Let's reset it again.

It may be that there is a problem with the local connection, so you should call the repairer.

1 The full cause may be as follows:

1.A yellow triangular exclamation mark is displayed, restricted, or no connection.

That's because the local PC failed to obtain the IP address after sending the DHCP request, and the router did not respond. This way the local PC will get a local IP.

2.There is no "restricted" message, but I can't access the Internet.

That's because you set the IP manually, and there is no link between this IP and the router, so you still can't ping and can't access the Internet.

Solution: (The hardware problem is troublesome and needs to be tested in many aspects).

Quote "Use a laptop to connect Tianwei Moderm directly with wire, check the DNS with ipconfig all, and record it. ", it should be the router to which it is connected. Ideas:

Troubleshooting (hardware issues are with the wireless card and the wireless sending part of the router, and the software part is in the settings).

1).Wired to the router, record the broadband account password, restore the factory settings, and try to set it up again.

2).Check if your laptop's wireless card is damaged;

3).Whether other computers can be connected wirelessly. There is no fixed method, only multiple tests.

The signal is not good, and in addition, sometimes he doesn't dial it up, and you can't get on.

It must be too far away and the signal is not good, so buy a wireless router yourself.

1.Too far away from too many sources of interference, 2It is recommended to buy a rubbing network card.

Do you see a wireless signal in the wireless list? If you can see it, you can receive a signal, but the connection or password is incorrect. If not, the wireless network location should be an x, there can be your wifi hardware switch turned off.

Open it with the corresponding key combination of fn + . Finally, it is determined that the network card is broken.

Hello! Based on the exclusionary steps that the landlord has done, I make the following suggestions:

1. Connect the cable from the second floor directly to a PC (without using a switch), if you can access the Internet, you can confirm that the problem is caused by this switch. In this case, the most likely problem is the port rate matching, you can manually modify the port rate of the router and switch (if this function is available), and generally set it to 10M full-duplex.

2. If the two PCs under this switch cannot ping each other, you can also confirm that it is a switch problem.

3. Still can't access the Internet. Try to replace the network cable, through the replacement method, you can eliminate them one by one, and finally find the problem.

According to the situation you provide, try to change the mode of the network card to 10M full duplex, because the network cable connectivity should be fine, it may be that the quality is not good, and the signal attenuation is relatively strong.

The above situation is generally because the DHCP of the router is not enabled, or the MAC and IP binding function is enabled in the security settings of the router.

If you're sure it's your home route, it's easy to do! The easiest way is to restore your router to its default, reboot it, and set it up!

From your question, it seems that the DHCP of the router has something to do with it, it may be turned off, click on. Or restart the router and restore the factory settings!

Or bind your own IP and MAC address. You don't need to set it up later. There are also restrictions that may be related to the network card, the best way is to restore the factory settings and set it up again. Fix the connection.

There are several reasons why you are only connected to a wireless network but not the Internet:

1. The wireless router has enabled a security firewall and enabled IP address filtering, and the IP address obtained by the device connected to the wireless network is within the range of being blocked from accessing the Internet;

2. Part of the network managed by the ISP operator connected to the router has a temporary failure and cannot connect to the Internet temporarily;

3. The broadband has expired, and you need to go to the business hall to pay for the renewal of the contract.

4. The router network parameters are set incorrectly, and the central office device cannot be dialed.

Proof that your wireless router's DHCP server is down.

If your manual IP address is incorrect, you will definitely not be able to access the Internet

Whether the router is connected to the network, if it is already connected, delete the network and reconnect to try @!

Refer to the network settings of your friend's book, he is automatically obtaining IP, you use automatic IP, he is specifying IP, you also have to specify IP, anyway, it can be set in the same mode as his book.

Brother, you take a look at your connection to see if the IP assigned by you is correct, and whether you can ping your machine to ping your company's wireless route... If you can't ping, it means that your computer's automatic IP is wrong, you can get the IP again.
