These appear as distinct networks in the list of available Wi-Fi networks. If your Wi-Fi networks list has both a 2.4 GHz network and a 5 GHz network, try to connect to the other network. To find out more about the differences between 2.4 GHz networks and 5 GHz networks, Wi-Fi Problems Activated Case and your reception arrangement.
Make sure the physical wi-fi switch on your laptop is activated. (Its activation is generally indicated by a light indicator.))
Run the network problem solving utility. The network problem solving utility makes it possible to diagnose and solve current connection problems.

To execute the network problem solving utility

Select To start up >Settings >System >Solve problems >Other problem -solving utilities .
Below The most common, select Network & Internet >Execute, or select the button below to start the network & Internet functionality get help.

Noticed : If you have a combined device-to-the-day/Wi-Fi route, you should only follow the single device steps.

Disconnect the supply cable from the power source router.
Disconnect the supply cable from the power source modem.

Limit the source of the problem

Connection problems can be due to various reasons: website problems, device, Wi-Fi router, modem or internet service provider (ISP). Try the following steps to refine the source of the problem.

If the “Wi-Fi connection” icon is displayed on the right side of the taskbar, visit another website. If the website opens, there may be a problem with the specific website. If you cannot connect to another website, go to the next step.
On another laptop or phone, try to connect to the same network. If you can connect, the source of the problem is probably due to your device. Access the network problem solving section on your device. If you cannot connect to the network on a device, go to the next step.
Check if there is a problem with connection to your Wi-Fi router. To do this, use a ping test.
1. Select To research in the taskbar, then type Command Prompt. The button Command Prompt appears. To the right of it, select Execute as administrator >Yes.
2. At the command prompt, type ipconfig, Then select Entrance. Look for the name of your Wi-Fi network in the results, then search for the IP address listed with regard to Default Gateway For this Wi-Fi network. Note this address if necessary. For example: 192.168.1.1
3. At the invite, type ping, then select Entrance. For example, type Ping 192.168.1.1, Then select Entrance. The results must look like this:

Response from 192.168.1.1: bytes = 32 Duration = 5 ms TTL = 64

Response from 192.168.1.1: bytes = 32 Duration = 5 ms TTL = 64

Ping statistics for 192.168.1.1: Packages: sent = 4, received = 4, lost = 0 (loss of 0 %), approximate round trip in millions second: minimum = 4 ms, maximum = 5 ms, medium = 4 ms

If you see results like this and you get an answer, you have a connection to your Wi-Fi router. There may therefore be a problem with your MoDem or your Internet Service Provider. Contact your Internet service provider or box activated online on another device (if you can) to see if there is a service failure.

If the Ping test results indicate that you do not get a response from the router, try to connect your PC directly to your modem using an ethernet cable (if possible). If you can connect to the Internet using an Ethernet cable, this confirms that the connection problem is due to the Wi-Fi router. Check that you have installed the most recent firmware and consult the documentation of your router.

Solve internet connection problems on Mac

If you cannot connect your Mac to the Internet, the problem may be linked to cables, devices, network settings or your Internet access provider (ISP).

Consult Wi-Fi recommendations or use wireless diagnostics

If problems related to Wi-Fi are detected on your Mac, you can consult these problems and solutions suggested. Click on the Wi-Fi status icon in the menu bar, then select Wi-Fi recommendations. Wi-Fi recommendations are not available for business networks or connection sharing.

You can use wireless diagnostics to solve problems related to a network that you have already configured.

Check a Wi-Fi connection

If you usually connect to the Internet using a Wi-Fi network, check that you are well connected.

If you are connected to the Wi-Fi network, but you cannot connect to the Internet, it is possible that the problem comes from your Internet connection. If you configure the Wi-Fi network using an Airport device (such as an Airport Extreme access terminal), you can obtain information on the device and its Internet connection using Airport utility. To get more help on Airport utility, choose Help> Airport Utility Help.

Check the condition of your network connections

Check your external cables and devices

Make sure all the cables are properly connected. If you use an external modem, make sure that one cable is firmly connected from this device to the computer and that the other connects the modem to a power outlet.

Check that all external peripherals, such as modems, concentrators and routers, are connected, are under voltage and have started completely. Try to reset these devices by disconnecting them for a few minutes, then reconnecting them.

Check the lights of the device to determine if it records a connection to the network and your computer. If a light does not light up, see the documentation provided with your device or contact your FAI.

Check your internet service

If all the above settings are properly configured and you still cannot connect to the Internet, contact your FAI. It is possible that its service is temporarily disturbed.
