Wi Fi problems, understand the computer, computer connection to the Wi Fi problem

Landlord. Hello.

First of all, your question, there are a few prerequisites required to set up a wireless network.

1.You need to have a wireless router or you need to be in a location with Wi-Fi coverage.

2.Your computer must have a wireless network card.

But from the problem you described, it seems that your computer should have a wireless network card, so I will tell you about the first case.

If you encounter any problems in the process of using it yourself, you can continue to ask me questions.

Hope it helps.

Generally speaking, there are two main types of reasons for not being able to access the Internet:

The first type is caused by physical reasons. For example, if the client's network cable is not connected or damaged, the switch to the client's network is disconnected, or the telecommunications party has a fault in accessing Zheng Xuan, etc., in addition to the first situation, several other situations need to be repaired.

The second type is caused by system or software reasons. This kind of situation can usually be solved by reinstalling the system or configuring the system correctly.

1.Both the mobile phone and the TV are connected to the Internet normally, which means that the wifi router is normal.

2.If the laptop can be connected to the Internet with a network cable, it means that the laptop network card is normal.

3.According to the above analysis, it should be that the wireless network card of the notebook is not normal, you can see whether the wireless network card is normal in the device manager, check whether the driver is normal, see if the wireless network card is operating normally, or reinstall it.

If it is still abnormal, it may be your wifi port or the hardware may be loose and not plugged in.

First of all, check if there is a problem with the NIC driver, and then restart the router if there is no problem.

Open Network & Sharing Center - Change adapter settings > Wi-Fi disable and re-enable.

It should be that the driver is not installed, so use the driver wizard to detect it.

When we are using a wireless network, sometimes we will encounter a computer that will prompt that we cannot connect to the wireless, then how can we solve this problem?

First of all, confirm the strength of the wireless signal, such as the wireless signal is too weak, the wireless information received by the computer is intermittent, which will cause the data to be transmitted or incomplete, in order to confirm whether the wireless password is correct, of course, in the case of a weak signal, it is very south to confirm whether the password is correct! It is recommended to move the computer to a place with a strong signal to confirm that the password is correct.

If the password is wrong, there will be a prompt!

4. If there is no problem with the above, we now check whether the NIC driver is normal.

Select "Computer" on the desktop, right-click and select "Manage".

5. Select "Device Manager".

6. Click Network Adapters

There are two main ways.

1. The traditional ADSL Internet access method is connected to the home by fixed network, and we connect to the Internet through modem dial-up. In this environment, we build our own wireless router in the back, dial-up Internet access through the wireless router, and we connect to the wireless router through wifi, so as to achieve wireless Internet access.

2. Most of them like KFC and Starbucks are wireless networks in this way, and your laptop can be connected to the Internet as long as you connect it, the reason is the same, but it eliminates the step of connecting to broadband.

3. In addition, it is connected to the mobile network through a wireless network card (HSDPA) to achieve Internet access.

The wireless networking of the computer is generally connected through the router, and the router is just a bridge to connect to the Internet. Therefore, wireless routers need to be connected to a broadband cat to achieve Internet access function. Otherwise, you can only access the router and cannot connect to the Internet.

Router dial-up, you can use it when you connect to it; If you want a computer to dial up, you have to dial the number first.

After the Wi-Fi computer is connected, why is it still connected to broadband?

Wireless and broadband are both network connection methods, as long as you connect one, you can use it!

You're probably talking about Wi-Fi and you're not connected at all, but connected via broadband!

Because the one you connect is broadband, routed wirelessly.

The other could be wifi so just go straight.

Is the IP set by the wireless route automatically assigned? Have you set up DNS?

It's a good idea to check if the DNS is set up.

You first log in to the routing interface to see if it is connected to the telecom normally.

You restart the router and press the button on the back of the router for a few seconds I forgot you go to the manual.

Do you turn on the wireless connection and see if the reception and sending are normal?

1All If you are using a wireless router, first connect with a smartphone to see if you can connect and surf the Internet normally, if the mobile phone also has problems, the router may have a problem with the settings, follow the steps on the manual to reset the router and reset the router.

If the phone can be connected and the Internet is normal (you can try other computers and mobile phones), then it may be a problem with the computer settings. Start - Network Connection - Local Connection - Right-click Properties - Double-click Internet Protocol to see if the IP is fixed. Generally, if you connect to a router, you can choose to get the IP address and DNS address automatically.

If you want to surf the Internet at other fixed network addresses, write down the IP and DNS (such as taking a photo) and select Auto Acquisition to see.

If you still can't solve it, because you don't know much about computers, then it is recommended to ask a repair shop or a friend who understands computers to solve it on the spot, or you can put a few typical **, so that you can analyze it in depth.

If you solve it, tell me, and so will mine.

It's OK to call telecom to change ** line...
