i ping my router, modem, and either local gateway or VPS continuously. if all have the same issue (packet loss, latency spike), then the problem is somewhere from the router inwards.
from here, it's a bit tougher for me. introduce a switch inbetween computer and router and ping another computer on switch to eliminate router. run iperf from router directly to computer or from another computer on switch (or directly connected) to test NIC hardware. beyond that, i'm out of ideas
I do have a wired router that I can use as a switch between the router and PC. I'll play around with that, thanks.
I removed the video card, as it was causing some minor video aberrations.
I don't want to change too many variables at one time, though.
UPDATE: After I removed the video card, I saw both time and Ethernet bugs. So that's not it.
I swapped the Ethernet cables for a system that works and the one in question after the problem PC lost connectivity. Instant fix! I could have sworn I did that before. So it could be either one bad port in the router or the entire router. Next I'll remove the current router and replace it with the older, wired one and run for a while.
I find it difficult to believe that the router causes time changes of six hours, though.

Thank you for contacting the Intel community.
Honestly, I have never heard if a processor can cause Ethernet issues, most likely Ethernet issues can be cause for a bad NIC, router issues, interference, bad Ethernet cable etc, also this could an issue on the NIC slot as well but I doubt it is the processor.
You can try doing some more tests on the processor with the Intel® XTU, with the XTU you can monitor, stress a system.
To really test if the processor can cause this problem which I doubt is to try with another processor, this will be the best way to do it.
No, I'm not sure, and that's a good point. The current cables are Belkin cat-6, bought maybe six months ago. This problem comes and goes with no apparent pattern, so I forgot that I had swapped cables before. But now that I'm using my old wired router -- both are blue Linksys from days gone by, with the wireless one having been flashed with DD-WRT -- both the time and Ethernet problems have disappeared. I need to use this new configuration for some time to make sure it is really gone.
