I am not knowledgeable enough to do a Window Reinstall.
My PC is around 12 years old.
Windows 10, 64 bit
It appears that you are experiencing intermittent internet connectivity issues on a Windows 10 PC. Since you have ruled out problems with your ISP and your router's Wi-Fi is working fine on other devices, the issue likely lies within your PC or its settings. Here are some steps that you can try to resolve the issue:
1. **Update Network Drivers**:
- Open Device Manager (you can search for it in the Start menu).
- Expand the "Network adapters" section.
- Right-click on your network adapter and select "Update driver".
- Choose "Search automatically for updated driver software" and follow the prompts.
2. **Check for Windows Updates**:
- Go to Settings > Update & Security > Windows Update.
- Click "Check for updates" and install any available updates.
3. **Disable Power Saving for Network Adapter**:
- Go back to Device Manager and Network adapters.
- Right-click on your network adapter and select "Properties".
- Go to the "Power Management" tab.
- Uncheck "Allow the computer to turn off this device to save power".
- Click OK.
4. **Run the Network Troubleshooter**:
- Go to Settings > Update & Security > Troubleshoot.
- Select "Internet Connections" and run the troubleshooter.
5. **Reset TCP/IP Stack**:
- Open Command Prompt as Administrator (search for "cmd", right-click, and select "Run as administrator").
- Type `netsh int ip reset` and press Enter.
- Type `netsh winsock reset` and press Enter.
- Restart your computer.
6. **Check for System File Corruption**:
- Open Command Prompt as Administrator.
- Type `sfc /scannow` and press Enter. Wait for the process to complete.
7. **Disable IPv6**:
- Go to Control Panel > Network and Sharing Center > Change adapter settings.
- Right-click your network connection and select "Properties".
- Uncheck the box next to "Internet Protocol Version 6 (TCP/IPv6)".
- Click OK and restart your computer.
8. **Check for Hardware Issues**:
- If possible, try connecting your PC to the internet using a different network adapter. This could be a USB Wi-Fi adapter or a different Ethernet card. If the problem resolves, your current network adapter may be failing due to its age.
9. **Reset Network Settings**:
- You've mentioned using Network Reset, but it's worth trying again after performing the above steps. Go to Settings > Network & Internet > Status > Network reset.
10. **Create a New User Account**:
- Sometimes, issues can be related to a corrupted user profile.
- Go to Settings > Accounts > Family & other users.
- Click "Add someone else to this PC" and follow the prompts to create a new user account.
- Log in with the new user account and check if the issue persists.
11. **Check for Malware Again**:
- Run another thorough scan with Malwarebytes.
- Consider using another antivirus tool to get a second opinion.
If none of these steps resolve the issue, you might consider backing up your data and performing a clean installation of Windows 10. Since you mentioned that you are not comfortable doing this yourself, it might be worth reaching out to a professional or a knowledgeable friend to assist you. A fresh install can often resolve persistent issues, especially on an older system that may have accumulated various software conflicts over the years.
