Не работает интернет на Windows 10

Based on my knowledge so far about this situation, I can give you some steps to follow and troubleshoot for it, try it out and then let me know the result

- Step 1: Check for Valid IP & DNS Resolution

• Open Command Prompt (Admin) and run:

ipconfig /all

You should check all of this informations bellow:

• Do you have a valid IPv4 address like 192.168.x.x or 10.x.x.x?
• Does Default Gateway point to your router?
• Is DNS Server something valid (like 1.1.1.1 or your router)?

If not skip and move to Step 3.

If yes, then run:

• ping 8.8.8.8
• ping google.com
  • If ping 8.8.8.8 works but ping google.com so it failed on DNS issue.
  • If both fail, it’s a deeper connectivity issue.

- Step 2: Full Network Stack Reset

• Even if you've already tried some resets, let's do a clean sweep.
• Open Command Prompt (Admin) and run these:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Then reboot your computer.

- Step 3: Driver & Adapter Check

Go to Device Manager:

• Expand Network adapters
• Right-click your Wi-Fi/Ethernet adapter → Uninstall device
• Check the box for "Delete the driver software for this device" if available.
• Reboot.

Windows will reinstall the default driver. If not:

• Use another PC to download the latest driver from the manufacturer (Intel/Realtek/etc.)
• Install it manually via USB.

- Step 4: Disable Proxy or VPN

Check if there’s a proxy or VPN interfering:

• Open Settings → Network & Internet → Proxy
• Turn off "Use a proxy server"
• If using any VPN software, uninstall it for now.

- Step 5: Safe Mode with Networking

Boot into Safe Mode with Networking:

• Press Win + R, type msconfig, go to the Boot tab, check Safe Boot with Network.
• Restart and see if the internet works.

If it works in Safe Mode, then a third-party app, firewall, or antivirus might be interfering.

- Step 6: BIOS/UEFI Reset + Firmware Update

Sometimes odd network behavior is tied to outdated or corrupted firmware.

• Restart PC → enter BIOS (usually F2, Del, or F10)
• Find the "Reset to default" or "Load optimized defaults" option
• Save and exit

*You can also check the manufacturer's site for a BIOS update.
