Fix network connection issues in Windows 10

   

• Restart your modem and wireless router. This helps create a new connection to your Internet service provider (ISP). When you do this, everyone that is connected to your Wi-Fi network will be temporarily disconnected.

The steps you take to restart your modem and router can vary, but here are the general steps:

1. Unplug the power cable for the router from the power source.
   
2. Unplug the power cable for the modem from the power source.
   Some modems have a backup battery. So if you unplug the modem and lights stay on, remove the battery from the modem.
   
3. Wait at least 30 seconds or so.
   If you had to remove the battery from the modem, put it back in.
   
4. Plug the modem back into the power source. The lights on the modem will blink. Wait for them to stop blinking.
   
5. Plug your router back into the power source.
   Wait a few minutes for the modem and router to fully power on. You can usually tell when they’re ready by looking at the status lights on the two devices.
   

On your PC, try to connect again.

• Generate a wireless network report. This report can help you diagnose the problem, or at least provide you with more information to give to others who might be able to help.

1. In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator & click on  Yes.
   
2. At the command prompt, type netsh wlan show wlanreport.
   
3. Make sure it’s not a problem with your cable modem or Internet service provider (ISP).If it is, contact your ISP. In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.
   
4. At the command prompt, type ipconfig.Look for the IP address listed next to Default gateway. Write down that address if you need to. For example: 192.168.1.1
   At the prompt, type ping  and press Enter. For example, type ping 192.168.1.1 and press Enter. The result should be something like this:

            Reply from 192.168.1.1: bytes=32 time=5ms TTL=64

            Reply from 192.168.1.1: bytes=32 time=5ms TTL=64

            Reply from 192.168.1.1: bytes=32 time=5ms TTL=64

            Reply from 192.168.1.1: bytes=32 time=5ms TTL=64
                      Ping statistics for 192.168.1.1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 4ms, Maximum = 5ms, Average = 4ms

•   If the ping is successful and you see results similar to the results above, but can’t connect to the Internet on your PC, there may be a problem with your modem or Internet service provider (ISP).

Run the Network troubleshooter followed by networking commands
