Why can t my laptop connect to the network?

The abnormal network connection may be caused by the wrong network connection, we can disconnect the wireless network first, use the password and reconnect again.

A WiFi wireless router actually converts a wired network signal into a wireless signal through a WiFi wireless router for computers, mobile phones, PDAs, etc. that support its technology. For example, ADSL at home, community broadband, as long as you connect a WiFi wireless router, you can realize wireless Internet access for WiFi devices.

Nothing more than these cases: 1The password is incorrect2

There is a problem with the network setup 3The wireless network encryption method is not compatible with the NIC. 4.

Wireless routers have security rules such as filtering. 5.Wireless network cards are not compatible.

Therefore, targeted, 1Verify password correctness 2Open the Control Panel of Network & Internet Network Connections, double click on Wireless Network - Properties - Internet Protocol Version 4 - Automatically Get IP Address, Automatically Get DNS Server Address.

3.Open the wireless router settings. Find the security option - turn off IP address filtering as well as MAC address filtering.

4.Change how the wireless network in your router is encrypted. 5.

If the network card is not compatible, there is no way but to replace the network card.

If the laptop can't connect to the network, one may be that his network card is broken or that it may be the reason of the system, restart the system, or there is a problem with the router, so the mobile phone or laptop can't receive it.

The problem of automatic IP acquisition, due to the large number of people connected to WiFi, the automatic IP acquisition cannot be obtained, or the router cannot automatically assign IP addresses due to failure, so you have to set it manually.

If the wifi signal is too weak, the wifi signal is too weak or too far, the computer will not be able to access the Internet.

If the router crashes, you can restart it.

If you are in arrears of broadband bills, you must pay the bills.

LAN software interception causes inability to access the Internet.

If the desktop can be linked, then you can plug this network cable into the laptop to try, if it does, then it proves to be a setup problem. If you still can't link to it, then it should be a problem with the notebook.

You can look at the attributes in the network link to see if you choose to automatically obtain the IP.

Try redoing the root cable.

A driver wizard with a network card driver installed, which contains diagnostics.

For example, if the "Startup Type" is "Disabled", right-click on the service and select "Properties", set the "Startup Type" to "Startup" on the interface that appears, click "Apply", then click "Start", and then click OK.

Once all the services involved have been completed, try to reconnect to the wireless network.

2. Use the slow key command to try to re-obtain the IP address.

Press the windows key and the R key at the same time, enter cmd and click OK, then enter "ipconfig release" and press the enter key, and then enter "ipconfig new" and press the enter key, it will try to obtain the IP address again, and you can test whether it can be successful.

3. If the above operations are invalid, you can try to reset the network configuration and then restart the computer for testing.

Press the Windows key and the R key at the same time, type cmd, click OK, then type "netsh winsock reset" and press the enter key, wait for the display operation to be successful, and then restart the computer for testing.
