My gaming pc is cruising right along with and downloading at speeds which are consistent with my connections, 100 down. Now when I download with my other PC, it is downloading very slow ...early DSL slow. Both are on a gigabit network fed from my main router, a ASUS 68u to a switch in my room which has bother PC's plugged into it, also gigabit. Adapters in both PC's say 1 Gbps and both PC's say the same thing when I run speedtest.net It's only when I download, one is drastically worse than the other. This is probably why my OBS streaming quality is shot. I swapped cables from one to the other and still the same thing as well as several different ports on the switch. 6700k - running great 3570k - not so much any ideas where I should check, or is the motherboard adapter foobar ?
