bad internet while rest devices are fine

Hi,

When you're experiencing slow internet on your PC while other devices on the same network are working fine, it could be due to several reasons, including but not limited to VPN remnants, misconfigured settings, hardware issues, or potentially unwanted software. Here's a structured approach to troubleshoot and hopefully resolve your internet lag issues:

1. Check for VPN Remnants

• Even though you've deleted the VPN, it's possible that some network settings altered by the VPN installation are still in effect. Check your network adapter settings to ensure no proxy or VPN connections are configured:
  • Go to Settings > Network & Internet > Proxy in Windows and ensure the proxy is off unless you specifically require it.
  • Check your VPN settings or applications to ensure nothing is running in the background.

2. Scan for Malware

• A virus or malware can significantly slow down your internet by using bandwidth in the background. Use a reputable antivirus program to run a thorough scan of your system. Windows Defender, which comes built-in with Windows 10 and 11, is a good starting point.

3. Network Troubleshooter

• Windows includes a network troubleshooter that can automatically find and fix problems.
  • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Internet Connections.

4. Check for Background Processes

• Some applications or processes might be using your network in the background, causing slow speeds.
  • Open Task Manager (Ctrl + Shift + Esc) and check the Network column under the Processes tab for any applications using a significant amount of your bandwidth.

5. Update Network Drivers

• Outdated or corrupted network drivers can cause internet issues.
  • Update your network adapter's driver by going to Device Manager > Network adapters. Right-click your network adapter and select Update driver.

6. Reset Network Settings

• Resetting your network settings can resolve any misconfigurations:
  • Go to Settings > Network & Internet > Status > Network reset. This will remove and reinstall all your network adapters and set other networking components back to their original settings.

7. Check Your Wi-Fi Signal

• If you're using Wi-Fi, try moving closer to the router or removing physical obstructions. If possible, connect via Ethernet to see if the issue persists, which can help determine if it's a Wi-Fi signal problem.

8. Limit Bandwidth Usage

• Windows 10 and 11 have a feature that allows you to limit bandwidth for updates:
  • Go to Settings > Update & Security > Delivery Optimization > Advanced options and set a limit for how much bandwidth is used for downloading updates in the background.

9. Router and Modem Reset

• Though other devices are working fine, a quick reset of your router and modem can sometimes resolve peculiar issues affecting only one device.

10. Consult Your ISP

• If none of the above steps work, there might be an issue with your ISP's connection to your PC specifically, though this is less common. It's worth contacting them if you suspect the problem might be on their end or if you've exhausted other solutions.

By methodically going through these steps, you should be able to identify and resolve the issue causing slow internet on your PC. If the problem persists, consider seeking assistance from a professional technician who can diagnose the issue in person.

though i did delete the vpn and nor it shows on settings i find it suspicious that it downloaded weeks after clicking download,

i don't know how to reset the router, says i am not the administrator when opening device manager, plus the internet keeps disconnecting while writing this and takes long just to connect again, i tried following others solutions to their same problem still none work , i don't know what to do at this point i'll just leave it to be.

maybe downloading an anti virus would work idk
