Very high ping on one out of two computers; has persisted for several days
I am experiencing a very strange situation.
I have two widows PC's which i use to stream Geforce Now. One is connected to the router by WIFI, and the other by ethernet. Both have normal (1-5ms ping) to the router.
However, the machine that is connected by ethernet is showing 150-250ms to the GFN servers & 120ms when running a speedtest. The wifi connected computer is experiencing 15-20ms, as usual.
Looking at the traceroute log on the problem machine, it says it is failing to reach the Geforce now server in the first attempt. That's about all i could derive from it. If anyone could advise the next appropriate course of action, i would be very grateful!
I have rebooted every in-house network related device (several times) & all drivers are up to date.
