I'm having trouble with my internet connection. I'm using an ethernet cable and it's strange because when I restart the router, the connection works for about a minute before it drops again. Other devices on my network are working fine. What might be causing this issue?

It sounds like there might be an IP address conflict on your local network. Try setting all your computers to use DHCP instead of static IPs, unless it's really necessary. You may also want to check your router's DHCP range and exclude the conflicting IP. Most routers set DHCP allocations between 100-200, so you could use IPs from 2-99 for static assignments. Good luck!
Given that your other devices work fine and you lose connection after just a minute post-reboot, it might be a local IP conflict or even a corrupted network stack on your Windows machine. Here’s what you can do:
1. **Flush the Network Stack:** Open Command Prompt as Administrator and run:
- `netsh winsock reset`
- `netsh int ip reset`
- `ipconfig /release`
- `ipconfig /renew`
- `ipconfig /flushdns`
2. **Check for Static IP Conflict:** Navigate to Control Panel > Network and Sharing Center > Change adapter settings. Right-click your Ethernet adapter, go to Properties, then IPv4, and make sure both options for obtaining an IP and DNS server address automatically are checked.
3. **Disable Energy Efficient Ethernet:** In Device Manager, under Network adapters, right-click your Ethernet controller, go to Properties, uncheck 'Allow the computer to turn off this device to save power', and set 'Energy Efficient Ethernet' to Disabled in the Advanced tab.
4. **Driver Rollback:** If this started after a Windows Update, consider rolling back the driver in Device Manager.
If none of this works, try switching to another port on the router or a different ethernet cable to rule out hardware issues!
