Hi Vlad,

You can try the below steps to fix the Internet connection problem.

1. Update the network adapter driver

An outdated or incompatible network adapter driver can cause connection problems. If you recently upgraded to Windows 10, it's possible that the current driver was designed for a previous version of Windows. Check to see if an updated driver is available.

1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. In Device Manager, select Network adapters > the network adapter name.
3. Right-click (or press and hold) the network adapter, and then select Update Driver Software > Search automatically for updated driver software. Follow the steps, then select Close.
4. After installing the updated driver, select the Start button > Power > Restart if asked to restart, and see if that fixes the connection issue.

2. Uninstall the network adapter driver and restart

Consider this approach if your network connection stopped working properly after a recent update.

1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. In Device Manager, select Network adapters > the network adapter name.
3. Right-click (or press and hold) the network adapter, and then select Uninstall > Delete the driver software for this device check box > OK to confirm you want to uninstall it.
4. After uninstalling the driver, select the Start button > Power > Restart.

After your PC restarts, Windows will automatically look for and install the network adapter driver. Check to see if that fixes your connection problem.

3. Temporarily turn off firewalls

Sometimes firewall software might prevent you from getting connected. You can see if the connection issue is caused by a firewall by turning it off temporarily, and then trying to visit a website you trust.

Make sure you turn it back on as soon as you can. Not having a firewall turned on makes your PC more vulnerable to hackers, worms, or viruses.

To turn off all firewalls

1. In the search box on the taskbar, type Command prompt, right-click (or press and hold) Command prompt, and then select Run as administrator > Yes.
2. At the command prompt, type netsh advfirewall set allprofiles state off, and then press Enter.
3. Open your web browser and visit a website you trust and see if you can connect to it.
4. To turn on all firewalls you might have installed, at the command prompt, type netsh advfirewall set allprofiles state on, and then press Enter.

4. Run these networking commands in a command prompt window

1. In the search box on the taskbar, type Command prompt, right-click (or press and hold) Command prompt, and then select Run as administrator > Yes.
2. At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
   • Type netsh winsock reset and press Enter.
   • Type netsh int ip reset and press Enter.
   • Type ipconfig /release and press Enter.
   • Type ipconfig /renew and press Enter.
   • Type ipconfig /flushdns and press Enter.

I hope this helps in solving your issue.
