How to fix bad local network connections?

Question

When I try to use my desktop for mostly any local internet connection it doesn't connect to the device properly or at all. An example of this would be using a quest 2 with air link but it being very delayed. It does connect to it but with high latency, my computer handles the quest completely fine when connected through a proper usb c cable so it can't be a performance issue. Other devices on the network connect fine to other local devices so i doubt it is a router issue I also have another windows 11 laptop on the network and all of its local connections work correctly. An example of my local networking not working properly would be when I use OpenSpeedTest, it does not allow other devices to connect BUT it works fine when I booted through an Ubuntu live install. The things I have tried to fix this issue are :booting into windows with safe mode and networking on, network resetting, checking router settings, uninstalling and reinstalling the network driver, changing ip configuration settings, using another network adapter via usb with it not working, using ip clearing commands in command prompt with administrator privileges, and making sure I'm using the private network setting with the proper sharing options on. This issue has been going on ever since I've gotten the computer and I don't know what could possibly be the issue, any help would be appreciated.

Thank you for providing detailed information about the issue you are experiencing with your local network connections. Based on the troubleshooting steps you have already taken, it seems that the issue may be related to the network adapter or its driver.

Here are some additional steps you can try to fix the issue:

1. Update the network adapter driver: Go to the manufacturer's website and download the latest driver for your network adapter. Install the driver and restart your computer.

2. Disable IPv6: Sometimes, disabling IPv6 can help resolve network connectivity issues.

To do this, go to Control Panel > Network and Sharing Center > Change adapter settings. Right-click on your network adapter and select Properties. Uncheck the box next to Internet Protocol Version 6 (TCP/IPv6) and click OK.

3. Disable firewall and antivirus temporarily:

Sometimes, firewall and antivirus software can interfere with network connectivity. Try disabling them temporarily and see if it resolves the issue.

4. Reset TCP/IP:

Open Command Prompt as an administrator and type the following commands one by one:

netsh winsock reset,

netsh int ip reset,

ipconfig /flushdns.

Restart your computer and check if the issue is resolved.

If none of these steps work, you may need to contact your computer manufacturer or network adapter manufacturer for further assistance.
