Hi Eric,
Sorry to hear you're having internet issues but thanks for writing into the forum!
So it sounds like your wireless works fine but when plugged in with an ethernet cable you're seeing packet loss starting at the first hop (your router) and going through to the final hop (in this case google.com). You also clarified that you are getting packet loss when plugged directly into the modem, correct?
This is going to be mostly more troubleshooting steps and the name of the game with troubleshooting is to eliminate as many parts of the system as possible until you narrow down where the issue is. You already know that it's an issue when you're plugged in with a cable and only on your gaming machine so this narrows things down quite a bit.
I would say a good place to start is to make sure that your TCP/IP stack is functioning as it should. Here are some steps that you can follow:
In the search on the taskbar, type CMD, right-click the command prompt result and then select Run as administrator and confirm.
At the command prompt:
- Type ipconfig /release and press Enter.
- Type ipconfig /flushdns and press Enter.
- Type ipconfig /renew and press Enter. (this will stall for a moment)
- Type netsh int ip reset and press Enter. (don’t restart yet)
- Type netsh winsock reset and press Enter.
Now restart your machine using Start > Power > Restart and check in PingPlotter to see if this makes a difference. If not the next thing to try is finding the IP address of your NIC card to see if the packet loss happens there. You can find your NIC IP by doing (once again in CMD) an ipconfig command and looking for the IPv4 address (likely 192.168.x.x or 10.x.x.x). Plug this IP into PingPlotter and see if you see the packet loss here. If you do then it's an issue with your NIC, if not then it has to be something between the NIC and the router/modem. If you haven't tried a known-good ethernet cable now is the time but it sounds like you likely already have.
If you're still having issues let us know and we're happy to continue to troubleshoot with you.
Let us know if you have any more questions and good luck!
Thanks,
