High Ping on 1 PC only
Discussion
I have a hard wired and wireless (mesh) network at home.
My office PC is connected directly to the router. I also have a gaming PC and server in another room which are connected via an unmanaged switch to the router.
The gaming machine and server are returning a ping of 8-10ms using speedtest.
The office machine is getting 30ms.
These are consistent results.
I've switched ports, switched cables, tried using the same cables/ports on a laptop (8ms result) so I have concluded it's the PC.
Removed the VPN software that I was using and that got the ping down for a while but then it went back to 30. Updated the NIC drivers which again worked for a while before reverting. Uninstall and re-install of drivers also worked for a while.
Running out of ideas. Help.

I had some more thoughts.
Tested in Chrome, IE and Edge. All get the same result (ie slightly slower).
Disabled and enabled the NIC, back to 7-8ms pings.
I'll see how long this lasts. Thinking its a memory leak type issue where the NIC gets clogged up after a while.
It will be better to test pings from the command line, not from a browser.Tested in Chrome, IE and Edge. All get the same result (ie slightly slower).

Try pings to your router or to the internet e.g. 8.8.8.8.
e.g. ping -n 100 8.8.8.8 to try for 100 seconds. FWIW, I get avg=16ms.
It will also show you fluctuations in performance.
What he said ^^
Run the same test from the machines at command line and compare the results. Ideally I’d even avoid using 8.8.8.8 as that’s a load balancer so it could still send you somewhere different; ideally run a trace route from one of your machines to 8.8.8.8 or similar and do your pings against the first hop outside of your home.
The next question from there of course is “but what problem are you trying to solve”. Is something not working?

There are a few software packages that enable multi-player real-time collaboration, for this you obviously need very low latency.
30ms doesn't really cut it for this but it's fine for most other things.
I've been using cmd line for some testing, the web stuff is just convenient for other devices than windows.
I restarted the NIC 1.5hrs ago now. I d/l a little app that pings an ip (I used 8.8,8,8) every 5 minutes and records the results. It started at 8ms and is now at 9ms.
I'll continue to monitor.

Ping your router's internal address instead and see if that increases. This will help establish if it's the NIC on the PC causing the issue.
If it does, I'd install Wireshark and capture the NIC in question to see if it is sending or receiving an unusual amount of traffic. The definition of unusual is a difficult one to explain - experienced Network Engineers know what looks right and what doesn't, but I'd be looking for a high number of packets being sent or received for a start - in the thousands per second for a Gigabit NIC, and the amount of broadcast traffic. Some broadcast traffic is inevitable and essential to the proper operation of a Ethernet network, but think of it like background noise - there will always be a bit and that's OK, lots of it and it drowns the sounds you actually want to hear.
